I and my colleague, Dr. Gökhan Akel are working on an edited book named "Digital Business and Optimizing Operating Strategies". It will be published by the IGI Global. The call was launched today, I wanted to share it with the RG community. We aim to recruit qualified chapters from various regions to make it international as possible. The official "call for chapters" page is:
Hello Peers,
I am deciding to change my research interest area to operations management. Based on your research and knowledge, what are the hottest topics and areas in OM (sustainability and supply chain management) that are being investigated these days (no pandemic, please)?
Textbooks about the managerial aspects of Digital Transformation and Industry 4.0 for academic teaching with exercises and case studies.
Dear Researchers,
I am interested to start some collaborative research work in Project Management/Operations Management Domain and publishing in ABDC/Scopus Q1/Q2 category journals.
My Google Scholar Profile and Scopus profile is for your reference.
Similar minded and similar research interest people can collaborate.
Could you recommend any recent research topics in Operations Management (OM)?
In your opinion, Which OM research topics will have the most influence in the coming decade?
Thanks for your attention. I’m looking forward to your kind reply.
What are some of the books that can be used at Business School (introductory level) that clearly delineate Operations Management and Supply chain Management courses? My interest is in how we can provide more value to our students rather than teaching similar topics in both courses.
Journal of Industrial & Management Optimization (JIMO) is an open access journal. You pay a substantial amount to publish a paper. When you go to the website of its publisher, American Institute of Mathematical Sciences (AIMS Press), it seems that it is not really based in the United States. I am not sure if it is a legitimate professional organization or if it is a predatory publisher. They have a large number of open access journals. On the other hand, their handling of papers is terrible: extremely slow and low-tech, which is not typical for predatory journals. It may take 13 months to get an editorial rejection, for instance. Furthermore, they don't have an online submission system with user profiles on it, you just submit the paper on a website, and they give you a URL to check your paper's status, which makes your submission open to anyone who has the URL. It has an impact factor of 1.3, which makes me puzzled. Any comments on this organization and the journal will be appreciated.
I am looking for examples from firms that have acknowledged the role of behavioral operations management/behavioral newsvendor models, cognitive biases in operations management, etc. It could also include some quotes from managers of the firms. Kindly provide some newslinks. Thanks a lot.
In the last month’s record if output=Rs. 20000, human input=Rs.10000, material input=Rs.2000, capital input=Rs.1000, energy=Rs.500 and other expenses=Rs.1000, calculate total factor productivity.
I am an MSc student studying Maritime Operations Management at Liverpool Johns Moores University. I am presently conducting a research project in assessing the impact of Brexit. The overall aim of this dissertation is to assess the impact of Brexit on ports in England. In order to achieve the research aim, this questionnaire is designed to be completed by experts who are working in the Maritime Industry or in the ports of England.
All the questionnaires answered will not be kept in any record, therefore, the responses will remain confidential only to be used by the researcher for the sole purpose of this reason only. It takes around 5 minutes to answer the questions.
Please send me a message if you have any question.
Thank you, I really appreciate your support.
I am interested in doing my doctoral research on a model for the strategy of operations in services but I want to be sure if one does not exist today
More specifically, I would like to find papers with a robust research methodology and providing the research questionnaire.
Thank you.
Some journals give reviewers 60 days, others give 40 days, 30 days, or 20 days to review a paper. MDPI journals give only 10 days, but it can be extended if the reviewer needs more time. In my opinion, 10 days might be too short, but 60 days is excessive. Allowing 60 days for a peer review is adding to the response time unnecessarily, and disadvantaging the authors. I can thoroughly review a paper in a day (if I dedicate myself to it), or two at most. A reviewer should only accept a review request if they are not too busy to do it in the next 10 to 20 days. I have encountered situations in which a reviewer agrees to the review, but does not submit the review at the end of 60 days, wasting those valuable 60 days from the author. What do you think the allowed time for reviewers should be?
Good Day to All,
As the world is becoming more VUCA it is difficult to manage the business operations.
In this scenario, how can we develop a simple yet effective solution for process owner and business leaders to face the Volatility; Uncertainty; Complexity and Ambiguity in business operation is a million dollar question.
Therefore I invite the members of RG to share their insights and thoughts over the impact of VUCA in business practices and how to develop viable solution that are easy to implement.
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.
Assume we have 5 service blocks in a system that requires the same resource unit. Say service block A and service block B have a service time of 1 minute each. Now I decide to combine these two blocks calling it service block X with a service time of 2 minutes. What should happen to the overall service time of the system? Will it go lower or will it remain the same? and why? Any proof from literature?
My experiment shows that the overall service time reduced.

In design and construction, there are many factors that can influence the occurrence of technical risk, which, as a consequence, affects the duration, quality and cost.
Technical risk is risk due to technical factors.
Example:
1. Low qualification of a specialist leads to low quality of project documentation.
2. Lack of BIM department.
3. Location of the facility (remoteness from the main manufacturing plants, difficulty in transporting equipment, etc.)
4.Use of new technologies, etc.
Dear all
I am working on an inventory model in closed-loop supply chain system to optimize the cost of the system. There are lots of model to optimize the cost of the system, but I am looking forward to incorporate the concept of the Analytics to handle the real time inventory.
Looking forward to hearing from you.

iv) assumes that all inventory records must be verified with the same frequency.
Dear colleagues,
I'm working on methodology of transforming existing organization for manufacturing companies. Could you please guide me on how to approach the following questions:
1. How to split task between operational routines (repetitive tasks, business as usual) and dynamic routines (transformations, NPD, innovation etc.) for different functions (sales, manufacturing, HR, etc.)?
2. How to calculate optimal number of people involved into each type of activities in different functions (e.g. dynamic routines in sales)?
3. How to approach motivation for different combinations of task types and functions? What KPI or other ways of performance control should be used for each of these combinations?
Thank in advance!
(Proposal) Oil Refinery Production: What is the company's goal?
----------------
[Purpose: get Engineers & Scientists thinking outside their box ... think -large- problems. What's possible today vs. needs for tomorrow?]
Question: Are you interested in increasing your sales income by several orders of magnitude? Are you willing to think outside the box? If so, please read on. This is a large proposal, the size of NASA's Apollo Space program back in the early 1960s.
A new level of Computers and Software will be required for this Oil Production proposal. Today's Computers are Algebraic, i.e. bare bones, conceived designs that run similar to a 'model T' car. They 'run' along at a '30 mph' clip. We need fast super Computers like the Wright Brothers 'Airplane' that can run at a '3,000 mph' clip. These super Computers need 'Automatic Differentiation' based technologies; i.e. smart thinking abilities. NASA realized this when starting the Apollo space program; spent tons to get it and put us on the moon.

Oil production depends on many factors; e.g. Supply, Demand, present inventory, etc. An oil company may have many refineries with many distillation units. How can a company simulate extracting products 'a', 'b', and 'c' from its crude oil? Assume the company wants product 'a' on the west coast, 'b' in the middle of US, and 'c' on the east coast. Assume the company has refineries 'x' on west coast, 'y' in middle US, and 'z' on east coast. How does one model such a company's oil production so as to produce/refine the 'right' amounts of each product at each refinery site in order to meet the company's goal of maximizing profits?
Partial Differential Equations (PDEs) will be used to model the crude oil distillation for each distillation unit at each site; i.e. many PDEs must be solved at once! Are there computers large enough to handle such problems today? Are there plans for some super computer that will be able to handle many (1,000s) PDEs at once?
With maintenance of distillation units being continual, e.g. fix one, stop another, this will be a constant problem when trying to simulate the next day's crude oil work load. For example, assume a company has 600 distillation units overall. That means a computer program would be required to solve 600 PDEs ASAP; i.e. 10 hours of PDEs. My past experience with modeling in FortranCalculus™ language/compiler, I was taught that a modeling requiring 'Tmod' time to execute the model, would require around 2'Tmod' time for the optimal solution. That would then get us into the 20 hr. time range for 600 PDEs. Too long! Need faster computers and solvers to get into reasonable solution times. Ideas how this could be done today? For more, visit http://fortrancalculus.info/apps/fc-compiler.html ... Solves Algebraic Equations through Ordinary Differential Equations.
Many people thought that the Wright Brother's idea of an 'airplane' would never fly. But, what if it did? What if Oil sales income doubled or more? Would crude oil prices increase? (Everyone is going to want more for their piece of the pie, right?) How would this effect your company?
John D Rockefeller was quoted saying, "If you want to succeed you should strike out on new paths, rather than travel the worn paths of accepted success."
Any future John D Rockefeller's reading this proposal? Are you interested in increasing your company profits by several orders of magnitude? Does your company have a company goal or objective that all employees know about and follow? If so, continue reading on this proposal by reading my article "Company Goal: Increase Productivity?" (a dozen pages). Go to web page eBook on Engineering Design Optimization using Calculus level Methods, A Casebook Approach and click on the 'download' link, its free!

I am currently testing a model that involves cross-level interactions. The dependent variable (corporate financial performance, a formative scale) and the independent variable (corporate sustainability performance, a formative scale) are measured at the firm level, and the moderator is a country-level variable. What software and/or statistical package can evaluate this model? I feel that I need a tool that combines the strengths of PLS and HLM.

In the last 25 years, outsourcing has emerged as one of the key globally focused supply chain strategies . After the mid-1990s, the importance of supply chain management (SCM) increased noticeably among practitioners. As a result, the study of supply chain and outsourcing has increased exponentially. In developing markets, with increasing customer demands, outsourcing non-core business
functions has become a commonplace supply chain strategy for many companies and organisations.

Hi everyone, I'm trying to map various business model canvases. The most widespread is the one proposed by Osterwalder and Pigneur (2010), but there are other ones, such as the Service Logic Business Model Canvas (Ojasalo and Ojasalo, 2015) or the triple layered business model canvas (Joyce and Paquin, 2016). Do you know and/or can you recommend any other one? Thank you, Luca

Good day,
I have been using systematic reviews to investigate and analyse specific knowledge areas (Product-Service Systems) and industries (medical devices) through the lens of Circular Economy business models.
I'm applying systematic literature review (Tranfield2003, Moher2009) of cases considering mainly secondary sources - published case studies for PSS and internet entries for medical devices. A deductive content analysis (Elo2008, Hsieh2005, Mayring2000) is used to analyse such cases.
I understand that systematic review of cases is widely used in Medical areas. I would like to know if anyone knows some widespread work on Operations management / Design research that makes use of a systematic review of cases to investigate a specific topic.
Also, is there any reference for such a methodology that I could borrow from medical areas or that already has been adapted to fields connected to social sciences?
Thanks for your time and let me know if I can be any more specific.

I am trying to optimize a function that is non-linear in parameters, three in number. I am using Genetic Algorithms (GA) for this purpose. Thus, I have a function of time that is non-linear in three parameters as time-series data. I am using the ga() function of the GA package in R language for the purpose. However, as I see, the initial values that I set for the parameters heavily influences the parameters computed by the ga() function. I also read the following article:
Scrucca, L. (2013). GA: a package for genetic algorithms in R. Journal of Statistical Software, 53(4), 1-37.
In section 4.4 Curve Fitting, if I use the following initial values (min, max): a(1000, 10,000), b(0,10), and c(0.5, 10) instead of the ones used, that is a(3000, 4000), b(0, 1) and c(2, 4) I get completely different results from the ones obtained by the paper. I get a=2772, b=.0235, c=4.07 as against a= 3534.741, b=0.01575454, c= 2.800797 in the paper.
My understanding is that global optimization techniques such as GA would be able to find out global optima irrespective of initial values although it might take more or less iterations depending on the initial values of parameters. Why is this not happening in case of my function and also the example that I cited?
Thanking you all in advance.

Is there any other factors that help Operations Management researchers decide about which type to of SEM (i.e. PLS-SEM or CB-SEM) to use other than sample size. Small sample size has been used as a determinant for using PLS-SEM. Is there any other facotrs that must be taken into consideration before choosing any of these two analysis methods?
Problem Statement:
A television manufacturer has decided to produce and sell two different types of TV sets, small and big. They assure that the small will give a profit of $300 per unit and the big a profit of $500 per unit. They have one production plant with four departments: molding, soldering, assembly and inspection. Each TV set is processed in sequence through these four departments. Each department has a limited capacity given by a maximum number of working hours per year. We assume that they can sell all the TV sets they are able to produce and the market is not a restriction.
Objective function:
•Max Z= 300x1+500x2……….(1)
Subject to the following constraints:
•x1+5x2<=4000………………(2) [Molding capacity]
•x1+x2<=1200………………..(3) [Soldering capacity]
•2x1+x2<=2000………………(4) [Assembly capacity]
•2x1+5x2<=5000……………..(5) [Inspection capacity]
x1,x2>=0……………………..(6) [Non-negativity Constraints
The dual is given by:
Min Z= 4000u1+1200u2+2000u3+5000u4
s.t. u1+u2+2u3+2u4>=300 [Small TV Sets]
5u1+u2+u3+5u4>=500 [Big TV Sets]
u1,u2,u3,u4>=0
My question is: What is the physical interpretation of the dual variables or u? Is it cost/hr or profit/hr for a specific operation?
If I consider cost, then the objective function is OK. But in case of constraints, cost cannot be greater than profit. Again, if I consider profit, then the constraints are OK. But the objective function profit cannot be minimized. I have gone through many books, but still I am confused. If anybody kindly helps me, I shall be highly obliged.

For my research work I, have identified following variables (eight variables namely inventory level, forecasting, finance capabilities, procurement policy, quality, manufacturing capability and process, logistics, and demand management), can anyone explain how can convert to the dimension.
Interesting project - reminds me of the problems I faced when forecasting sales when scheduling production - there I tried to do several things to reduce the impact of uncertainty.
1. Apply effort to reduce the uncertainty associated with the most important items.
2. Separate uncertainty into those where I could improve my knowledge of the item (sales trends and seasonality) and where I could not improve my knowledge ("random" fluctuations due to weather etc.)
3. Improve "agility" appropriately (so as to speed response) when actuals differed significantly from forecast - holding inventory at a sub assembly level, buffer stocks.
4. Flag and investigate situations where the actual was an outlier - such as a customer changing the product that it bought routinely (despite sale saying that this was a purely random blip!!).
Also, I think that the quality management knowledgebase may be a good source of ideas.
The Popular sayings, " What gets measure gets attention” or “What you measure is what you get," inform that measurement is an important concept to reach our targets and meet our goals! This time, Performance measurement is considered to be a means to bring organization excellence among others. following this, a number of CPMS ( Contemporary Performance Measurement Systems) has been developed to the extent that selection of appropriate performance measurement systems becomes challenging. Therefore, would you suggest me the best manufacturing company which implemented CPMS and can be used as a benchmark for future adoption?
I'm doing a research within a MTO environment. The capacity levels within this company are based on historical data. The order realization of past year is used as input for the "product mix (named by the company)" to measure capacity and set capacity levels for the next year, on product family level (in volume).
When the product mix change time over time, due to the MTO environment, the historical data (the product mix) is not representative for future demand. So, the capacity levels are not reliable what results in lower operations performance and accepting too much or too less orders.
Do any of you know a approach of method to determine these capacity levels in a MTO environment or how to calculate this product mix in MTO. Could this by using e.g. forecast techniques? Sources that wrote about this topic are scarce.
The critical theory can use the human view of the employee, to develop a more accurate process management. What do you think?
Is there a standard in how to determine or calculated a resource planning as input for S&OP and MPS? Without an accurate resource planning will be a S&OP and MPS also not be reliable. I can't find any paper which describe this process. Same problem for product mix calculation/forecasting.
The single-supplier multi-retailer joint replenishment game can be stated as follows: a number of independent retail facilities know demands of a single product. They order goods from the same supplier. All shipment from supplier's warehouse to retailers are direct. Both of transportation costs and linear inventory holding costs are supported by the retailers.
A group of retailers would like to form and alliance and replenish their inventory jointly to save on delivery costs. Now, the questions are:
1. Which are the alliances that are more likely to be formed?
2. How should the retailers fairly apportion their achieved savings?
