Hello,
I am currently formulating an optimization model that integrates vehicle routing problem and vaccine supply chain. The model includes delivering vaccines to vaccination centers and on-spot locations representing individuals requesting to be vaccinated at home. The objective function includes maximizing the amount of doses delivered to both customers but, since the number of doses demanded by vaccination centers is significantly larger than on spots'. the model will just focus on delivering to vaccination centers and ignore the other since its effect on the objective function value is negligible. I tried to solve this by multiplying the on spot's term by a factor representing the ratio between both demands to make them equally important to the model. but I kept getting biased results. So, I formulated 2 different objective functions where each objective maximizes one customer doses why having a constraint that forces the vehicles to deliver a specified percentage of the demand of the other customer.
my question is: can I consider this model as bi-objective and treat the objectives as conflicting ?since maximizing one of these objectives will be on the account of the other taking into account that both objectives have the same unit.
Relevant answer
Answer
Dear Yury
I guess that you can use the SIMUS method, that allows for using as many objectives as you want, it does not matter if some of them are contradictory.
This method is based on Linear Programming, but does not prouce optimal solutions (no MCDM method can do that either), as different from LP that can give you optimal results, but based on only one objective.

n commerce, supply chain management (SCM), the management of the flow of goods and services,[2] between businesses and locations, and includes the movement and storage of raw materials, of work-in-process inventory, and of finished goods as well as end to end order fulfillment from point of origin to point of consumption. Interconnected, interrelated or interlinked networks, channels and node businesses combine in the provision of products and services required by end customers in a supply chain.[3]
Supply-chain management has been defined as the "design, planning, execution, control, and monitoring of supply-chain activities with the objective of creating net value, building a competitive infrastructure, leveraging worldwide logistics, synchronizing supply with demand and measuring performance globally".[4][5]SCM practice draws heavily on industrial engineering, systems engineering, operations management, logistics, procurement, information technology and marketing,[6] and strives for an integrated, multidisciplinary, multimethod approach.[7] Marketing channels play an important role in supply-chain management.[6] Current[when?] research in supply-chain management is concerned with topics related to sustainability and risk management,[8] among others. An important concept discussed in SCM is supply chain resilience. Some suggest that the “people dimension” of SCM, ethical issues, internal integration, transparency/visibility, and human capital/talent management are topics that have, so far, been underrepresented on the research agenda.[9] Supply chain management (SCM) is the broad range of activities required to plan, control and execute a product's flow from materials to production to distribution in the most economical way possible. SCM encompasses the integrated planning and execution of processes required to optimize the flow of materials, information and capital in functions that broadly include demand planning, sourcing, production, inventory management and logistics -- or storage and transportation.[10]
Although it has the same goals as supply chain engineering, supply chain management is focused on a more traditional management and business based approach, whereas supply chain engineering is focused on a mathematical model based one.[11]

What is your view in relation to Lean Manufacturing impacting the recovery from COVID19? Can we blame lean for stock less production, which lead to shortages in supply chain? Or is lean going to be a critical factor in the recovery process?
Relevant answer
Answer
I think your are correct Just In Time Methodology means you are not holding inventory which is good from a monetary point of view and also good from a space point of view. However, when supply chains are strained this causes constraints because you are running hand to mouth.
However, in other ways lean has been utilised during this pandemic for the greater good. We combined it with digitalisation methodology to implement Online Lean Training which has been pretty successful we have had over 9,000 completed attempts on our training since 2020. This combined with other engagement and motivation strategies has allowed us to improve a lean engagement and adherence to the Lean Systems and Tools. This is essential during this period i.e. ensuring we have effective problem solving, working in a standardised manner, identifying anomalies and improvements and implementing Kaizens.
If you are interested have a look below at two of the conference papers we recently published and we have another currently under review, hopefully for publication this year.

In the wake of disruption in supply chains fueled by circumstances outside and beyond our control, the discourse then is not necessarily centered on how to build lean supply chains. Extant literature suggests that organizations that practice lean philosophy are more vulnerable to risks and disruptions and thus may take a long time to recover, and bounce back to a state of normalcy. In light of the above assertion, practitioners, academics and experts in recent times are changing the direction of supply chain discourse laying emphasis on building a more resilient organization. Thus, creating organizations that can withstand shocks both from within and outside their control is the expected 'norm'. Building resilient organization necessitates management to undertake activities such as having redundant supplies, facilities, inventories, having slack resources, among others. These practices are in contravention with lean philosophy. Although lean is a great tool that aids in eliminating waste, under the prevailing situations in today's supply chain, is it logical and or, empirically relevant to suggest that lean's potency rather seems insignificant?
Relevant answer
Answer
I think Lean has its place. Within the Factory Walls Lean is still a necessity, maybe even more so at the moment. Volumes have been affected by parts shortages due to the pandemic. However, turnover / profit can be increased by reducing waste, utilising the Kaizen process, driving the reduction of waste in the process and improving quality and improving FTT.
But I agree in some instance it can be a hindrance. Especially if the organisation is running hand to mouth with parts i.e. Just In Time Methodology.

Since many suppliers were disrupted due to the COVID-19, disruption risk arouses reserachers' attention. The literature I have ever read can be divided into two parts. The first one is the probability that a disruption risk event happens, and the second one is the severity of disruption on a supply chain. They may use Bayesian network to locate the most risky node or risk triggers, or use Perti-net to identify the risk propagation path through calculating changes in parameters like on-delivery rate and pocuremnet cost. I would like to know if there are any different methods applied in supply chain disruption analysis, or are there any new/hot research branches of a supply chain from the disruption risk perspective. Thank you all for your apply!
Relevant answer
Answer
Bayesian network can use to identify the relationship between variables and to calculate probabilities. But If we consider down stream SC, it's mainly covering through 7 segments as follows,
RAW Material
Inbound logistics
Inbound warehousing
Manufacturing
Outbound warehousing
Outbound Logistics
Customer
COVID 19 conditions are affected to all above sectors.
Out of which with my experience and knowledge, Inbound and out bound logistics created the main bottleneck to trigger this supply chain disruption.
We can analyze above 7 segments in detail separately with available data in the market. This will give you a better picture about the condition and where it has disrupted mostly in this chain.

During the last half year in the U.S. the consumer price index has risen between 5 and 6%, the highest percentage increase seen since 1990-91. Given the enormous amount of economic and social change and uncertainty unleashed by the covid pandemic, are people's inflationary expectations also rising in this new and very different environment of the 2020s? Are supply chain disruptions, a switch back toward relatively more goods consumption, rather than services, all likely to persist into the future as the U.S. economy, along with those of the rest of the world, struggles to stay ahead of the covid pandemic with all its new incarnations ( delta, omicron, etc)?

The Supply chain council's SCOR model is a very famous and widely used model in many scientific publications for assessing supply chain performance. The model is as simple as it is effective and consists of five main processes: source, plan, make, deliver and return.
This model is certainly very intuitive and effective when analysing a manufacturing industry supply chain, but it starts to falter when considering other sectors.
In particular, if you want to use this model to analyse a retailer's supply chain, how can you translate the "make" process? Although the SCOR model is also used in many articles to study retailer supply chains, I have not been able to find any references that help me understand how to translate the "make" process in contexts other than manufacturing.

Background of the problem for people non familiar with transfusion:
Every day, hospital transfusion services must guarantee they have enough blood to meet patient transfusion demand. This is very like managing a food stock in a refrigerator but even easier (just one product, one expiration date).
Assumptions:
- RBC (red blood cell) units are kept on a refrigerator with enough capacity
- Maximum expiration date for RBC is 42 days.
- We make a routine order to the blood bank provider (our grocery store) every day from Monday to Friday. We can make additional orders if we run out of stock.
- We practice first in first out.
The model should satisfy the following targets:
- Minimize the expiration rate (the number of RBC units expiring every certain time)
- The less time on the refrigerator the better (eat fresh)
- Avoid extraordinary orders as much as possible (some extraordinary order might be considered to cope with transfusion peaks of demand)
- Note: I have purposely simplified the problem (no considerations of ABO group distribution, crossmatched reserved units, or reduced expiration date of the irradiated blood…).
Non controlled external factors:
- Transfusion rate
- Average remaining time to expiration of the received blood.
What we are looking for is the optimal number of RBC units we must order on a routine basis (M-F) which is the only factor we can adjust to optimize the equation. Resulting figure must be recalculated when transfusion rate or average expiration date of the received units change.
Intuitively, I see how the number of extraordinary orders and RBC freshness are at opposite sides of a balance, because if a higher number of extraordinary orders is tolerated, then it should result in a smaller but fresher RBC inventory. On the other hand, in order to avoid extraordinary orders, you need a greater inventory thus increasing the average age of your products and the risk of expiration.
Any idea or suggestion? Any available script on Excel/SPSS/Stata/R/SQL? Any related bibliography?
I can provide raw data for simulations on demand if someone want to make a collaboration.

There are notable supply chains related to traditional and regional products that are still untouched by contemporary progress in supply chain management. The basic problem in SCM for these products lie in the lack of a descriptive reference model to even initiate SC research. Although SC mapping is still in an early stage in terms of design, it has been applied to bring out visualization of processes as well as complete industry SCs. Hence a question has been raised seeking the compatibility of SC mapping approaches for solving SC visualization problem. Do other methods available produce better results in visualization when compared with SC mapping approaches?
Relevant answer
Answer
SC mapping remains a good method of visualisation especially in traditional activities characterised by stability and repetitiveness of practices. Also, each modern or traditional activity is characterised by specificities and particularities that are perfectly captured by SC mapping.

Current consumption and production patterns are increasingly founded in global value chains (GVC). Typically, GVCs are structured in several tiers distributed across countries and including a wide set of activities (design, production, distribution, etc). Given the current situation of industrial development and energy transition, comprehensive assessments are required to understand how supply chains work and where they are located. In this sense, which are the most appropriate indicators for mapping supply chains? According to the high availability of trade data (e.g., from Comtrade database), could the trade performance indicators (e.g., relative trade balance or Balassa index) be suitable for identification of net exporters or importers of commodities within the supply chain under evaluation?

I'm using ubiquitin-AMC as the substrate for deubiquitination assays with several different deubiquitinases. Normally I'd do the assay in 50 mM HEPES (pH 7.5) and 150 mM NaCl, which I know works well. However I'm about to use two new deubiquitinases with estimated pI of 7.2 and 7.8 respectively, potentially crashing out at pH 7.5. I need to change the assay pH but every paper I find uses Ub-AMC at pH 7.5. Does anyone have any experience with it at alternative pH? I'm worried it won't be as active or the assay will be distorted
(NB: I know I could buffer samples at a range of pHs and check if they're in solution and if fluorescence is impacted, but reagents are running low and I don't trust supply chains right now)

I am currently busy with my PhD on omnichannel supply chain integration. I am struggling with the correct “terminology” in terms of omnichannel. It seems that most authors simply use “channel” or “online/offline channel”. However, since I am investigating omnichannel from a supply chain perspective, my supervisors feel that “channel” is too broad. For example, depending on the part of the omnichannel process I am discussing – the website could serve as both a communication OR distribution channel. My supervisors feel that it would dilute the managerial recommendations at the end of the study since channel is ambiguous. The suggestion at this stage is to use the word “omnichannels” instead of channels (as it is more inclusive than merely using channel).
For example:
“Shopping by means of a variety of omnichannels is no longer novel but has become universal for both consumers and retailers (Cummins, Peltier & Dixon, 2016: 12). Customers expect consistent, uniform, integrated services and experiences, regardless of the omnichannel they use. Customers are willing to move seamlessly between their preferred omnichannel depending on their current situation, the time of day, or the product category.”
My question(s) for other authors writing within the field of omnichannel retailing:
1) Do you think the ambiguous use of “channel” dilutes the understanding of omnichannel retailing?
2) How do you explicitly differentiate between the different uses of “channel” (as touchpoints and fulfilment channels) to clear up the ambiguity WITHOUT creating reader fatigue?
Attach is a table with a summary of the terms used across omnichannel. I attempted to answer my own question with this table – but ended up creating more questions than answers.
I thank you in advance for your time and input in this regard.

What Is the Impact of Omni Channel Commerce on Supply Chains
What Is the Impact of Omni Channel Commerce on Supply Chains
By Marina Aleksic / June 30, 2020
As retailers move from traditional brick-and-mortar shops selling to a mix of brick-and-mortar and online stores, they face numerous supply chain challenges. Retail stores sell directly from stock. While some online retailers can do the same, many rely on third-party distributors and suppliers to ship and fulfill them.
The catch is that online merchants will send several individual orders to consumers on the same day, while department stores only provide walk-in customers with products out of stock.
What is Omni Channel Supply Chain
Omni channel supply chain serves consumers across various channels. However, omni channel solutions provide one-touch integration across all channels to provide a superior customer service experience.
Omni channel solutions give consumers the flexibility to ship items to their homes or stores from ecommerce sites. Consumers can also choose to complete online purchases, and then pick the item from the store itself. If an item is not available at the store, consumers can order it from their smartphone and wait for it to be delivered.

Relevant answer
Answer
Hi Sanjeevkumar,
A one year masters does not stop you from going for a PhD. However, you need to clarify if it was a taught (professional) masters or a research masters program as this will determine which direction your further studies will go.
If you had a taught program, you will have to continue in a taught program e.g. if had an MBA, you can proceed with a DBA or any other professional program. However, to continue with a research PhD, you will need to get a research based masters program.
Various universities in Europe have different choices for particular courses, thus, do not rule out the possibility of pursuing your PhD in Europe as possibilities abound. So, go to any school of your choice's website and check for their requirements for the course of your choice. However note that a PhD is not necessarily about the course but the topic you are interested in. Your research interest might be supply chain but you could find a supervisor who is interested in the topic under engineering, environmental or any other department. Just don't stereotype yourself. As I always say, opportunities abound.

Hi,
My current qualitative research (for my master thesis) looks at how a company can respond better to scarcity in its supply chain. My theoretical framework consists of the whole supply chain risk management process and defines characteristics that I'm comparing to determine if missing one of the characteristics could explain the success or lack of success. But before I could answer the 'why' it was a success or not, I need to analyze 'if' it was a success.
The company has a lot of data available. I defined a few variables that determine 'success' (e.g., percentage the company can fill regarding customer demand). Is there a methodology that describes how to look at the available data? The closest methodology I could get was descriptive statistics, but I'm not sure if it covers everything I want to do. Can somebody help me with this?
Relevant answer
Answer
Your statement “The company has a lot of data available” is true but the shortcomings in the supply chain are mainly due to variables external to the company (if management is good enough).
Let's take an example from the recent experience of the pandemic and the difficulties on the global / local market for goods; o climatic reasons: shortage of food / feed; or even purely political reasons.
Maybe, it could be better to focus on one type of market and analyze a broad and qualitative economic / political variables.

In my study,I have 1 independent variable (Big data analytics capabilities )and 1 dependent variable (sustainable supply chain performance) and 3 moderators Total 49 questions were included in the survey and I got a sample size of 73 respondents. my target respondents (CIOs) and IT managers Now after CFA many of the factor loadings are exactly 0.5 then .5 but the standard is .6 so is it possible that I consider factor loading with .5. Please argue with references. Thanks
Relevant answer
Answer
Hello Baraah,
low loadings are most often a sign of model misspecification and model misspecification most often results on lack of knowledge what a common factor model really means. The consequence is that a heterogeneous set of measures that reflect completely different thing (but share some "topic" or "domain") are pressed in a factor model.
See these threads as a bit of background and references
I guess this is the case in your model, too. Can you present (as an attachment) the items of at least some of the "factors".
And apart from that: Don't follow these strange .6 rules of thumb. A CFA model is a model that claims a certain data/response generating process. Hence, there are two things to consider:
1) Is the model correct and do the data give me some sign that something is wrong (=misfit)?
2) Even if I have no counterevidence and even if the structure is correct: Can I have confidence that the latent variable reflects the latent attribute that I think it represents? Loadings and other structural or relational coefficients give you some hint about this. They are validity coefficients. Hence, you must ask yourself the question: "given my assumed understanding of the latent attribute and the question wording of the item: Is it reasonable to get a relationship/effect estimate of size ".xx"). Coefficients of .5 or .6 may be reasonable but in many other cases, they are not (e.g., when the indicators are crystal clearly formulated and have a small conceptual difference to the latent attribute).

Two important indicators that In my opinion need to be added are:
  1. Quality: What is the quality of goods or services, ordered from a vendor. Statistical Process Control (SPC) methods come handy in terms of this indicator. Are batches, delivered by a certain vendor within our quality limits or there are non-conformaties? Have vendors been informed about our SPC approaches, such as, specification, control limits, sampling methods, in-control or out-of-control rules, etc. ?
  2. Lead time: How reliable are vendors in terms of delivery of goods or services, ordered from them. Are vendors delivering goods, according to agreed lead times or there are some deviations? How often those deviations happen?

One of the ideas that came to me was that supply chains could function like a human body - Thinking, Anticipating, Reacting, and Responding to problems/issues.
I dug some details and discovered that very little research is being conducted in this field. I am not sure whether to move forward on my research in sentient supply chains or just stick to Supply chain Automation (Artificial Intelligence and Machine Learning). Yes, 10PL might be too far as of now, but I believe its not unattainable.

Laxman Marathe Indeed, the bottleneck defines the throughput only for a simple linear sequence of events or processes. The best analysis of this kind is presented in the famous and well-known book by Goldratt, E., Cox, J., 2004. 'The Goal.' 3-rd Ed., North River Press, Great Barrington, MA, p. 384.
A well-known book by W. Hopp and M. Spearman 'Factory Physics', McGraw-Hill, 3rd edition (2008) illustrates in detail how to structure the firms' environment so that it attains the speed and low cost of high-volume flow lines while retaining the flexibility and customization potential of a low-volume job shop. The authors compare and contrast common problems, including shop floor control, long-range aggregate planning, workforce planning, and capacity management.
A book by Kolker, A., 'Healthcare Management Engineering: What Does This Fancy Term Really Mean?' Springer, NY, 2012 provides multiple examples of applications management engineering/operations research methodology in Healthcare /Hospital settings. The last section 'Summary of some fundamental management engineering principles' includes a summary of the general management principles that play a role of laws of physics in natural sciences. Specifically,
  • The higher the degree of randomness in arrival rate and service time, the lower the unit's operational performance in terms of queue size, wait time, and unit's utilization.
  • Reduction of process variability is the key to patient flow improvement, increasing throughput, and reducing delays (illustrated in section 2.3.6).
Discrete event simulation is the best-known methodology for the analysis of the throughput, variability, and interaction of the various manufacturing or service units. Thus, all points in your post are already well-known and no “bottleneck gurus” are needed at all for a competent factory manager.

In daily life single period and multi period inventory system is very necessary things. When the selling period is fixed that is we cant sell things outside that fixed time then it is called may be single period. Lets talk about it what is the actual definition.
Relevant answer
Answer
Single period inventory models are used typically for determining the optimal order quantity for a perishable product. The most famous example is the Newsboy (Newsvendor) problem, in which the demand for newspapers for a given day is random, there is a cost of overstocking (unsold papers) and understocking (lost profits). The objective is to minimize the expected daily cost and the decision variable is the number of papers to buy (for reselling). this model is useful for any other item that cannot be stocked to be sold in another period, you have to sell it during the period or it is wasted. Many products fit this category: Christmas trees, Halloween costumes, or any other item that is special day or event themed. Fresh produce and meat can be though of in this category as well.
On the other hand, multi-period models are used for items that can be stocked for long periods of time, and demand in subsequent periods can be satisfied from the inventory. The basic EOQ model is the simplest of these models.

Maybe have a look at how the transition from offering products to offering services (e.g., rental cars instead of car ownership) reduces the incentives for manufacturers to produce products for the scrap yard. Companies can then make profit not by intentionally convincing consumers to buy new product generations as fast as possible (smartphone industry: every 2-3 years), but by intentionally building durable products to be shared by users. This will lead to entirely different supply chains and keeps resources in the loop. I wrote about this only a bit in my new paper (Dancing...). Another interesting question is culture: For example, Starbucks with their throw-away coffee cups are not successful in Italy, where it has been a tradition to drink coffee "al banco", i.e. to share espresso cups, which is circular per se.
