ere has been consensus that logistics as well as supply chain management is a vital research eld, yet with few literature reviews
on this topic. is paper sets out to propose some hot issues in the current research, through a review of related literature from the
perspective of operations management. In addition, we generate some insights and future research directions in this eld.
1. Introduction
Organizations adopt numerous business improvement
methodologies to improve business performance. Logistics
as well as supply chain management has been regarded to be
the crucial factor for the companies to obtain competitive
edge. In fact, logistics as well as supply chain management
has received attention since the early 1980s, yet conceptually
the management of supply chains is not particularly well
understood, and many authors have highlighted the necessity
of clear denitional constructs and conceptual frameworks
on supply chain management. In this paper, we provide a
tutorial on the current research of operations management of
logistics and supply chain. We rst clarify the conception of
logistics and supply chain management in this paper, which
denes the scope of our related research papers. e core of
this paper is that we provide several hot issues in this eld
with examples to show how these researches contribute from
dierent research angles. Finally, we conclude the paper with
the insights obtained from our analysis and future study
directions in this eld.
e paper is organized as follows. In the next section, we
specify the denitions of the terms of logistics and supply
chainusedinourpaper,withacomparisonbetweenthesetwo
popular conceptions. In Section 3, which is the core section of
this paper, we provide several hot topics in current research
with detailed examples. In Section 4,weprovideinsightsand
further research directions.
2. Conception and Scope
2.1. Logistics. Logistics is the management of the ow of
goods between the point of origin and the point of consump-
tion in order to meet some requirements, for example, of cus-
tomers or corporations. e resources managed in logistics
can include physical items, such as food, materials, animals,
equipment, and liquids, as well as abstract items, such as time,
information, particles, and energy. e logistics of physical
items usually involves the integration of information ow,
material handling, production, packaging, inventory, trans-
portation, warehousing, and oen security. e complexity of
logistics can be modeled, analyzed, visualized, and optimized
by dedicated simulation soware. e minimization of the
use of resources is a common motivation in logistics for
import and export.
Note that the above denition of logistics is not uni-
ed, although it might be indeed, in current environment,
a commonly acknowledged one. For example, Council of
Logistics Management (now renamed as Council of Supply
Chain Management Professionals) referred to logistics as “the
process of planning, implementing, and controlling the ecient,
eective ow and storage of goods, services, and related
information from point of origin to point of consumption for
the purpose of conforming to customer requirements,” w h i c h
includes inbound, outbound, internal, and external move-
ments and return of materials for environmental purposes.

Aswecansee,theconceptoflogisticsfocusesontheprod-
uct ow, which is the meaning by which this word has been
translated in Chinese. It also puts emphasis on the activities of
handling product, which include the storage, transportation,
distribution, and packaging and processing. Although busi-
ness logistics involves many activities, the traditional research
of operations management on logistics mainly relates to
the elds of logistics facility, transportation, and inventory
planning.
2.2. Supply Chain. Compared to “logistics,” there appears
to be even less consensus on the denition of the term
“supply chain management.” Kathawala and Abdou [1]point
out that SCM “has been poorly dened and there is a high
degree of variability in people’s minds about what is meant.”
Nevertheless, we present a rather widely adopted denition,
which is given by Mentzer et al. [2]whichisratherbroad,
not conned to any specic discipline area, and adequately
reecting the breadth of issues that are usually covered
under this term: “Supply chain management is dened as
the systemic, strategic coordination of the traditional business
functions and the tactics across these business functions within
a particular company and across businesses within the supply
chain, for the purposes of improving the long-term performance
of the individual companies and the supply chain as a whole.
e terms of “logistics” and “supply chain” are usually
comparative in academy and industry, since both of them are
closely relevant to the product circulation during its whole
lifecycle,andbothhavebeenregardedasthecentralunitof
competitive analysis of model management science. Gener-
ally speaking, supply chain is a more broadened conception
with a wider range which can involve other similar subjects,
such as network sourcing, supply pipeline management, value
chain management, and value stream management [35].
In addition, we can see that the conception of logistics has
no relationship with organization, which is the opposite of
supply chain, since supply chain is made up of multiple orga-
nizations, usually companies. An important issue in supply
chain management is that companies will not seek to achieve
cost reductions or prot improvement at the expense of their
supply chain partners but rather seek to make the supply
chain as a whole more competitive. Hence, the contention
that it is supply chains, and not a single company, that
compete is a central tenet in the eld of supply chain man-
agement [6]. A central research metho dology for supply chain
management is game theory (and also incentive theory for the
scenario of incomplete information).
3. Hot Issues
Due to the extensive research ranges in operations manage-
ment of logistics and supply chain management, we cannot
possibly make a comprehensive review in one paper. In this
section, we point out several of the most important issues
and hot topics in recent research, which draws great attention
from both academy and industry.
3.1. Inventory and Transportation Management on Specic
Fields. As has been pointed out in the previous section,
theoperationsresearchonlogisticsmanagementstillmainly
focuses on the traditional domain, that is, the inventory
(including production planning) and transportation manage-
ment. However, a noticeable phenomenon is that most papers
are putting emphasis on specic elds with remarkable fea-
tures captured into their models and thus making new con-
tributions to the literature.
For example, the inventory management of perishable
products (also referred to as deteriorating product) is a rather
old and mature eld in logistics and supply chain manage-
ment, with replenishment policies for inventory being the
main focus of study. Whitin [7] investigated such a problem,
where fashion goods deteriorating at the end of certain
storage periods were considered. Since then, considerable
attention has been paid to this line of research. Nahmias
[8] provides a comprehensive survey of research published
before the 1980s. Studies in recent years on the deteriorating
inventory models can be found in Raafat [9] and Goyal and
Giri’s [10] papers, in which relevant literature published in the
1980s and 1990s is reviewed, respectively. A more updated
review is given in Blackburn and Scudder’s [11]paper.How-
ever, new models can still be developed to capture the current
management feature and obtain new managerial insights.
Generally, two types of perishable loss, quantity loss and
quality loss, may take place for a perishable product. e
majority of the literature has dealt mainly with only one
typeofloss.Inthisregard,Caietal.[12]adoptastochastic
modeltostudyasupplychaininwhichadistributorprocures
from a producer a quantity of a fresh product. During the
transportation process, the distributor has to make an appro-
priate eort to preserve the freshness of the product, and his
success in this respect impacts both the quality and quantity
of the product delivered to the market. Cai et al. [13]further
extend the model into a 3-stage supply chain with outsourcing
transportation involved.
Another important eld is transportation. It is generally
known that the research on VRP (vehicle routing problem)
and its various extensions has been extensive. However,
other new domains on transportation can still be interesting
topics. For example, the remarkable growth in intermodal
transportation over the past decade has not been matched
by a comparable level of academic activity, and, hence, the
research on intermodal transportation appears to have a great
potential. Chang [14] explores one of the intermodal opera-
tional issues: how to select best routes for shipments through
the international intermodal network. e problem is for-
mulated as a multiobjective multimodal multicommodity
ow problem with time windows and concave costs, and an
ecient heuristic is proposed. Vermaa and Verter [15]present
a rst attempt for the development of an analytical frame-
work for planning rail-truck intermodal transportation of
hazardous materials by developing a biobjective optimization
model to plan and manage intermodal shipments to represent
the current practice; the routing decisions in the model are
driven by the delivery times specied by the customers.
Bruns and Knust [16]studytheproblemofloadplanning
for trains in intermodal container terminals. e objective
is to assign load units to wagons of a train such that
the utilization of the train is maximized and setup and
Discrete Dynamics in Nature and Society 3
transportation costs in the terminal are minimized. Bruns et
al. [17] further study the problem of robust load planning
for trains in intermodal container terminals. e goal of
load planning is to choose wagon settings and assign load
units to wagons of a train such that the utilization of the
train is maximized and setup and transportation costs in the
terminal are minimized. Garc´
ıa et al. [18]adoptanewhybrid
approach by combining OR techniques with AI search meth-
ods in order to obtain good quality solutions for complex
intermodal transport problems, by exploiting the benets
of both kinds of techniques. e solution has been applied
to a real-world problem from one of the largest Spanish
companies using intermodal transportation.
3.2. Sourcing and Marketing in Supply Chain. Sourcing is the
rst step in a supply chain. e research on sourcing has
been extensive in recent years. is leaves open room for a
supplier to improve eciency over time by further optimizing
the production processes. In general, OEMs’ shiing of more
development and engineering work, which require complex
tasks and customized products, to their suppliers implies a
signicant potential for a supplier to accumulate knowledge
and experience from learning, thus reducing costs over time
[1921]. is dynamic change of supply costs aects the
negotiation of sourcing contracts.
A noticeable issue is the utilization of auctioning in the
sourcing strategy. One of the rst researches in this regard
might be Chen’s [22], which studies a procurement problem
with one buyer and multiple potential suppliers who hold
private information about their own production costs. An
optimal procurement strategy is considered for the buyer who
rst species a payment for each possible purchase quantity
andtheninvitesthesupplierstobidforthiscontract.e
auctioncanbeconductedinmanyformatssuchastheEnglish
auction, the Dutch auction, the rst-priced auction, sealed-
bidauction,andtheVickreyauction.ChenandVulcano[23]
study a supply chain where an upstream supplier auctions
his inventory or capacity as a bundle, which formulates the
problem as a two-stage supply chain comprising a single
supplier and two resellers. Huh and Janakiraman [24]study
periodic-review inventory replenishment problems with auc-
tions and other sales channels and show that the optimality of
(s, S) inventory replenishment policies extends well beyond
the traditional sales environments studied so far in the
inventory literature. Chen et al. [25,26] study a supply chain
in which a single buyer wishes to procure a package of
products or services from various competing suppliers that
possess private cost information and show how the buyer
can optimize his/her prot and at the same time coordinate
the channel by using a contract scheme involving auctions,
audits, and prot sharing.
For a supplier that provides critical and customized
components, the demand closely depends on, and hence is
susceptible to, the variation of the nal product demand. In
the automotive industry, unstable and uncertain domestic
volume of individual models is cited as one of the biggest
challengesfacedbymanufacturersduetoincreasedconsumer
choices [27]. e consumer electronics industry is notorious
for risk stemming from short product life cycles and high
demand uncertainty [28]. Furthermore, there is typically
moreuncertaintyaboutthefuturedemandthanaboutthe
current demand. is demand uncertainty adds another
source of future uncertainty, besides possible supplier switch-
ing (in a short-term relationship), that inuences the decision
of initial capacity investment.
Marketing is another end in supply chain. e collabora-
tion with marketing science massively extends the domain of
supply chain management. Pricing, promotion, and channel
management are the three most important areas in this
regard. Pricing and promotion are the central issues in mar-
keting management, let alone under consideration of the sup-
ply chain environment. Li and Graves [29] explore the pricing
decisions during intergenerational product transition, by
formulating the dynamic pricing problem and deriving the
optimalpricesforboththeoldandnewproducts.eoptimal
initial inventory for each product is also determined, and a
heuristic method is discussed. Li and Zhang [30]studythe
preorder strategy that a seller may use to sell a perishable
productinanuncertainmarketwithheterogeneouscon-
sumers. ey nd that accurate demand information may
improve the availability of the product, which undermines
the seller’s ability to charge a high preorder price. As a result,
advance demand information may hurt the seller’s prot
due to its negative impact on the preorder season. Sainathan
[31] considers pricing and ordering decisions faced by a
retailer selling a perishable product with a two-period shelf
life over an innite horizon. Sinitsyn [32]investigatesthe
outcome of a price competition between two rms, each
producing two complementary products. It is found that each
rm predominantly promotes its complementary products
together, which is correlationally supported by data in the
shampoo and conditioner and in the cake mix and cake
frosting categories. Liu et al. [33] examine the ecacy of cost
sharing in a model of two competing manufacturer-retailer
supply chains who sell partially substitutable products that
may dier in market size. Some counterintuitive ndings sug-
gest that the rms performing the advertising would rather
bear the costs entirely if this protects their unit prot margin.
Gao et al. [34] show that the weather-conditional rebate
program can increase sales by price discriminating among
a customer’s postpurchase states. Taking advantage of the
early sales, it can also reduce the inventory holding cost and
ordering cost and hence can increase the retailer’s expected
prots.
In addition, channel management is also an important
interface between marketing and supply chain. Chen et al.
[25,26]studyamanufacturersproblemofmanaginghis
direct online sales channel together with an independently
owned bricks-and-mortar retail channel, when the channels
compete in service. ey identify optimal dual channel strate-
gies that depend on the channel environment described by
factors such as the cost of managing a direct channel, retailer
inconvenience, and some product characteristics. Brynjolf-
sson et al. [35] investigate local market structures for tradi-
tional retailers and then match these data to a dataset on con-
sumer demand via two direct channels: Internet and catalog.
eir analyses show that Internet retailers face signicant
competition from brick-and-mortar retailers when selling
4 Discrete Dynamics in Nature and Society
mainstream products but are virtually immune from com-
petition when selling niche products. Guo [36] investigates
optimal disclosure strategies/formats in a channel setting
with bilateral monopolies and shows that retail disclosure
leads to more equilibrium information revelation. Chiang
[37] extends the single-period vertical price interaction in a
manufacturer-retailer dyad to a multiperiod setting, in which
a manufacturer distributes a durable product through an
exclusive retailer to an exhaustible population of consumers
with heterogeneous reservation prices. e open-loop, feed-
back, and myopic equilibria for this dynamic pricing game
are explored and compared to the centralized solution.
3.3. Green Logistics and Supply Chain. Green logistics refers
to a logistics form which plans and implements green
transport, green storage, green packaging, green circulation
processing, green recovery, and other activities via advanced
logistics technology. It aims to reduce environmental pollu-
tion and resource consumption arising from logistics activ-
itysoastorealizea“win-win”consequenceinlogistics
development and eco-environmental conservation. As an
important avenue for realizing the sustainable development
strategy, greater attention has been given to green logistics
which will play an important role in industrial upgrading,
transformation of economic structure, promotion of logistics
development level, and other relevant aspects. Green supply
chain is the supply chain management with similar objectives
and core implications. Green logistics as well as supply
chain management is also usually referred to “sustainable”
management.
A typical eld in green logistics and supply chain man-
agement is reverse logistics, sometimes called closed-loop
supply chains, in which there are reverse ows of used prod-
ucts (postconsumer) back to manufacturers. ere has been
substantial research into production planning and inventory
management in remanufacturing systems. Simpson [38]rst
studies a periodic review inventory system with stochastic
and mutually dependent demands and returns and provides
the optimality of a three-parameter inventory policy. Kelle
and Silver [39] consider a dierent model with independent
demand and return processes, where all returned products
should be remanufactured. Inderfurth [40] shows that the
optimal policy derived by Simpson [38] is still optimal in
thecaseofxedcostwhenleadtimesforremanufacturing
and manufacturing are identical. Van der Laan et al. [41]
analyze a push control strategy and a pull control strategy
in a hybrid system and compare them with the traditional
systems without remanufacturing. Teunter et al. [42] explore
the superior inventory strategies for hybrid manufactur-
ing/remanufacturing systems with a long lead time for man-
ufacturing and a short lead time for remanufacturing. Wang
et al. [43] analyze the impacts of the amount of products
manufactured and the proportion of the remanufactured part
to the returned products on the total cost of the hybrid
system, showing that the cost could be reduced signicantly
if these two critical values are optimally set. Other related
works include Kiesm¨
uller [44], Tang and Grubbstr¨
om [45],
Aras et al. [46]. For a comprehensive review, I refer the reader
to Fleischmann et al. [47], Dekker et al. [48], and Ilgin and
Gupta [49].
A typical feature in reverse logistics and closed-loop sup-
plychainsisthequalityuncertaintyofacquiredusedproduct,
which is usually expressed by a random remanufacturing
yield and has been studied in some recent papers. Inderfurth
[50] shows that the uncertainty in returns and demand can
be an obstacle to an environmental-benign recovery strategy
within a reverse logistics system. Inderfurth and Langella
[51] develop heuristics for the problem of obtaining parts
for remanufacturing by disassembling used products or
procuring new ones, under the consideration of random
disassembly yields. Galbreth and Blackburn [52] explore
acquisition and sorting/remanufacturing policies in the case
of a continuum of quality levels for cores with xed quality
distribution. e main premise is that remanufacturing costs
will go down if only the returned products with better
quality are remanufactured. Ketzenberg et al. [53] explore
the value of information in the context of a rm that faces
uncertainty with respect to demand, product return, and
product remanufacturing yield by rst analyzing a simple
single-period model and then proving that the results carry
over multiperiod setting. C¸ orbacioˇ
glu and van der Laan [54]
analyze a two-product system with end-product stock con-
taining both manufactured and remanufactured products
while the remanufacturable stock may contain products of
dierent quality. Zikopoulos and Tagaras [55] investigate the
production problem in a reverse supply chain consisting of
two collection sites and a refurbishing site and examine how
the protability of reuse activities is aected by uncertainty
regarding the quality of returned products. Denizel et al. [56]
propose a stochastic programming formulation to solve the
remanufacturing production planning problem when inputs
of the remanufacturing system have dierent and uncertain
quality levels and capacity constraints.
Although the research on remanufacturing systems is
vast, there are only a few papers that consider a market-driven
acquisition channel for used products. Guide and Jayaraman
[57] and Guide and van Wassenhove [58]arethersttoinves-
tigate this eld, pointing out the importance of used product
acquisition management to deal with the uncertainty in
timing,quantity,andqualityofthereturnedproducts.Guide
et al. [59] develop a quantitative model to determine the
optimal acquisition prices of used products and the selling
price of remanufactured products, assuming that the quantity
of return items can be fullycontrolled by the acquisition price.
Bakal and Akcali [60] extend the model of Guide et al. [59]
into the case of random remanufacturing yield and analyze
the impact of yield on the remanufacturing protability.
Karakayali et al. [61] study the problem of determining the
optimal acquisition price of the end-of-life products and the
selling price of the remanufactured parts under centralized
as well as decentralized remanufacturer-driven and collector-
driven decentralized channels.
3.4. Behavior Operations. e decisions under the con-
sumers’ behavior are important for the rms to gain com-
petitive edge and obtain more prot. e customer’s behav-
ior can be loss averse, risk averse, regretful, and strategic,

increasingly important. K¨
ok and Xu [62]studyassortment
planning and pricing for a product category with heteroge-
neous product types from two brands by modeling consumer
choice using the nested multinomial logit framework with
two dierent hierarchical structures: a brand-primary model
in which consumers choose a brand rst and then a product
type in the chosen brand and a type-primary model in which
consumers choose a product type rst and then a brand
within that product type. Nasiry and Popescu [63]study
the dynamic pricing implications of a new, behaviorally
motivated reference price mechanism based on the peak-end
memory mode, which suggests that consumers anchor on a
reference price that is a weighted average of the lowest and
most recent prices. ey nd that a range of constant pricing
policies is optimal for the corresponding dynamic pricing
problem. Nasiry and Popescu [64] further characterize the
eect of anticipated regret on consumer decisions and on rm
prots and policies in an advance selling context where buyers
have uncertain valuations. Tereyaˇ
goˇ
glu and Veeraraghavan
[65] propose a model that addresses pricing and production
decisions for a rm, using the rational expectations frame-
work.eyshowthatrmsmayoerhighavailabilityof
goods despite the presence of conspicuous consumption and
scarcity strategies are harder to adopt as demand variability
increases. Parlakt¨
urk [66] considers a rm that sells two
vertically (quality) dierentiated products to strategically
forward-looking consumers over two periods, setting the
prices dynamically in each period. It is found that the loss
duetostrategiccustomerbehaviorcanbelesswithtwo
product variants compared to the single-product benchmark,
which indicates that product variety can serve as a lever when
dealing with strategic customers. Cachon and Swinney [67]
consider a retailer that sells a product with uncertain demand
over a nite selling season, with three types of consumers:
myopic, bargain-hunting, and strategic consumers. ey nd
that the retailer stocks less, takes smaller price discounts,
and earns lower prot if strategic consumers are present than
if there are no strategic consumers, and a retailer should
generally avoid committing to a price path over the season.
Another stream of research focuses on the risk attitude
of the rms in the supply chain. Lau’s [68]mightbethe
rst piece of work that studies the newsvendor boy problem
under mean-variance framework, which takes the variance
ofsystemprotorcostintotheutilityfunction.Otherrecent
works employing similar methodology to investigate supply
chainproblemincludeH.S.LauandA.H.L.Lau[69]on

coordination, and Wei and Choi [72] on wholesale pricing
and prot sharing scheme.
4. Insights and Future Directions
Fromtheaboveanalysis,wecanabsorbthefollowinginsights
and future directions in the area of operations research of
logistics and supply chain management.
First, the logistics issue regarding the people’s livelihood
becomes a hot spot. e traditional research in this regard is
relatedtoperishableproduct,fashionproduct,andelectronic
product, which have short life cycle. Nowadays, such topics
might include city logistics, emergency logistics, and agricul-
ture supply chain.
Second, new directions on logistics and supply chain
management can be brought about by the development of
economy and technology. A typical example is the informa-
tion technology which leads to the research on e-business and
related distribution channel choice. Nowadays, the common
usageofRFID,cloudtechnique,andbigdatacanbeimpor-
tant research directions for future study.
ird, the environmental related research will continue
to be big issue. With the steady increase in global population
and economic scale, resource crisis, ecological damage, envi-
ronmental pollution, and other issues have drawn universal
concern. It has been the consensus of the international
communitytoattainsocioeconomicsustainabledevelopment
through a greener economic pattern and lifestyle. Many
countries create a new outlook in industrial and technical
competition by increasing investment in the green logis-
tics and supply chain eld, formulating and implementing
variousbills,plans,andstrategies,andstrengtheningthe
implementation of green economic development strategy. In
the future, the range of this topic will not only be just reman-
ufacturing, reverse logistics, and closed-loop supply chain.
Low-carbon issues can be an important research direction.
Finally, multimethodology is an important direction for
future study. Traditionally, major research methodologies in
operations management can be classied into several cate-
gories, such as theoretical modeling, computation and sim-
ulations, surveys, cases, event studies, and behavioral exper-
iments. In recent years, there is an emerging trend towards
combining multiple research methodologies to explore
research problems in logistics and supply chain management.
For example, in addressing the issues of supply chain coor-
dination, some papers establish the respective models and
verify the ndings by real-world cases and some papers con-
duct behavioral experiments with the goal of exploring the
real-world relevance of some theoretical models. Moreover,
the number of the papers with new applications of the
existing methodology, such as cooperative game and behavior
operations, is expected to grow continuously.

Supply chain management (SCM) is a critical management function in any organization. After the pandemic in 2019, the global supply chain faced drastic disruptions, compelling policymakers worldwide to seek ways to manage them. Integrating artificial intelligence (AI) technologies into supply chain processes has revolutionized it. Predictive analytics is a vital tool that helps supply chain managers anticipate future trends and make informed decisions. Based on statistical principles and machine learning algorithms, predictive analytics encompasses techniques such as linear regression, decision trees, cluster analysis, time series models, and logistic regression. Unlike traditional supply chains, which often lack visibility, supply chains integrated with predictive analytics offer enhanced transparency. Mastering these intelligent technologies becomes imperative for organizations seeking to thrive in today's dynamic market landscape. This chapter provides readers with a comprehensive grasp of predictive analytics and its indispensable role in SCM processes.

Perencanaan (planning) merupakan fungsi dasar manajemen yang penting. Fungsi ini membantu menentukan langkah-langkah yang diperlukan untuk mencapai berbagai tujuan organisasi. Perencanaan mencakup keputusan awal tentang apa yang harus dilakukan, kapan, di mana, bagaimana, dan siapa yang akan melakukannya. Perencanaan adalah proses yang melibatkan pemikiran sebelum bertindak. Fungsi manajemen lainnya seperti pengorganisasian, pengarahan, koordinasi, dan pengendalian dilakukan setelah perencanaan. Proses perencanaan mencakup beberapa tahap: pengumpulan informasi, penetapan tujuan, pengembangan strategi, peninjauan alternatif tindakan, evaluasi tindakan, peninjauan batasan, dan pelaksanaan rencana (Daft, 2021; Powley, Edwards, 2012).

Purpose The research proposes a customised framework for improving logistics service quality (LSQ) in Tanzania's railway transportation, focusing on customer engagement and integrating customer-desired services. Design/methodology/approach The survey method obtained data from railway customers regarding the LSQ offered. Both probability and purposive sampling techniques were used to get the sample size. The open- and closed-ended questionnaires gathered the pertinent data. The data were analysed qualitatively and quantitatively using the IBM® SPSS® 21.0 and AMOS 21.0 software packages, respectively. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were performed to analyse data and establish relationships between variables. Findings This study anticipated that the LSQ framework during the period of reviewing literature included three variables for freight transporting customers (tangible components, ways of fulfilment and information actions) and eight variables for passengers (tangible, reliability, assurance, responsiveness, comfort, empathy, connection and convenience). EFA and CFA dropped some factors. The retained factors were used as inputs to develop a framework. The qualitative analysis also established the improvement of customer’s desired services (CDS) and LSQ, which were the framework's processes for improving the LSQ. Ultimately, the study developed the LSQ framework for railway transportation. Research limitations/implications The study was conducted on Tanzania’s railways, which incorporated challenges in the Tanzanian context. However, many challenges in the developing countries are relatively the same. Therefore, modifications can be made to adopt the developed framework and be used in other countries to cover the geographical and other challenges in particular countries. Originality/value Tanzania’s railway infrastructures are somehow not fully utilised to meet the actual needs of the transportation sector. For example, one of the railway companies has a built capacity of 4 million tonnes carrying capacity per year, but the actual cargo transported by the railway is 200,000 tonnes. This comes from several challenges within the railway companies, including the quality of their services, thus leading to a need to develop a LSQ framework.

This paper studies the preorder strategy that a seller may use to sell a perishable. product in an uncertain market with heterogeneous consumers. By accepting preorders, the seller is able to obtain advance demand information for inventory planning and price discriminate the consumers. Given the preorder option, the consumers react strategically by optimizing the timing of purchase. We find that accurate demand information may improve the availability of the product, which undermines the seller's ability to charge a high preorder price. As a result, advance demand information may hurt the seller's profit due to its negative impact for the preorder season. This cautions the seller about a potential conflict between the benefits of advance demand information and price discrimination when facing strategic consumers. A common practice to contain consumers' strategic waiting is to offer Once guarantees that compensate preorder consumers in case of a later price cut. Under price guarantees, the seller will reduce price in the regular season only if the preorder demand is low; however, such advance information implies weak demand in the regular season as well. This means that the seller can no longer benefit from a high demand in the regular season. Therefore, under price guarantees, more accurate advance demand information may still hurt the seller's profit due to its adverse impact for the regular season. We also investigate the seller's strategy choice in such a setting (i.e., whether the preorder option should be offered and whether it should be coupled with price guarantees) and find that the answer depends on the relative sizes of the heterogeneous consumer segments.

A manufacturer must choose to delegate component procurement to her tier-1 supplier, or to control it directly. This paper examines how asymmetric information regarding production costs affects the optimality of delegation versus control, by abstracting from other known drivers. Assuming that firms use simple quantity discount or price-only contracts, as is common in practice, either delegation or control can yield strictly higher expected profit for the manufacturer. Delegation is optimal when the manufacturer is uncertain about the tier-1 supplier's cost and believes that it is likely to be high, when the tier-1 supplier has better information about the tier-2 supplier's cost than does the manufacturer, and when the suppliers' costs are strongly correlated. Conversely, control is optimal when the manufacturer knows the tier-1 supplier's cost or believes that it is likely to be low and when the manufacturer has better information about the tier-2 supplier's cost than does the tier-1 supplier.

Economic, marketing, and legislative drivers increasingly are leading companies to take back and recover their products after use. The arising product flows pose novel challenges for supply chain management. This book addresses decision making in reverse logistics. It covers a wide range of aspects, related to distribution, production and inventory management, and supply chain management. For each topic, it highlights key managerial issues in real-life examples and explains which quantitative models are available for addressing them. By treating a broad range of issues in a unified way, the book offers the reader a comprehensive view on the field of reverse logistics.

In this paper, the problem of robust load planning for trains in intermodal container terminals is studied. The goal of load planning is to choose wagon settings and assign load units to wagons of a train such that the utilization of the train is maximized, and setup and transportation costs in the terminal are minimized. However, in real-world applications, many of the parameters needed for the model are not known exactly. Since feasibility of the resulting load distribution has always to be guaranteed, we decided to use a robust approach. In particular, we apply the concepts of strict and adjustable robustness to enhance the load planning problem. Based on a formulation developed in Bruns and Knust (OR Spectrum 34:511-533, 2012) for the deterministic load planning problem, we propose mixed-integer linear programming formulations for most of the respective robust counterparts, dependent on the type of uncertainty. An experimental study shows that most of the robust problems can be solved within runtimes of a few minutes, which is good enough for real-world applications. Furthermore, our results indicate that robust solutions may improve the planning considerably, and that it is promising to add robustness even to large mixed-integer programs with many and diverse technical constraints.

Remanufacturing requires that used products (cores) be obtained from the end-user at the end of their current life cycle so that the value-added may be recovered and the products returned to functional use again. The acquisition of cores to be remanufactured in such recoverable manufacturing systems is a complex set of activities that requires careful coordination to avoid the uncontrolled accumulation of core inventory, or unacceptable levels of customer service. The authors report on current industry practice via an extensive survey of North American remanufacturing firms. The authors propose a formal framework for Product Acquisition Management (PrAM) to coordinate, monitor, and provide an interface between reverse logistics and production planning and control activities. Finally, a series of managerial guidelines for the organization of PrAM activities is proposed. We conclude that managers should take actions that consistently reduce the variance inherent in a remanufacturing environment.

I consider pricing and ordering decisions faced by a retailer selling a perishable product with a two-period shelf life over an infinite horizon. In the first period, the product is “new”; in the next, it becomes “old.” The new product is perceived by customers to have a higher quality than the old product. Every period, the retailer makes three decisions: prices for the new and old products and how much new product to order. I first show, with some simple cases, that demand uncertainty can make the sale of the old product profitable. I then consider a more realistic case with dynamic demand substitution among customers. I recognize that the retailer's decisions may be constant or may vary across different periods, under different contexts. For instance, varying the price of the new product can sometimes be difficult due to the negative impact it generates among customers. I find that (i) the benefit obtained from selling the old product with constant decisions is much higher than the benefit from allowing all the decisions to vary; (ii) the former benefit increases with a higher procurement cost, a higher quality of the new product, and higher demand volatility; however, the latter benefit is non-monotone in these parameters; (iii) most of the latter benefit can be obtained by just changing the order quantity; and (iv) as the inventory of the old product increases, when all the decisions vary, the optimal price of the new product may increase or decrease.
