Prof. Ruiz

Short Biography:

RUBEN RUIZ is a Full Professor of Statistics and Operations Research at the Polytechnic University of Valencia, Spain. He is co-author of more than 100 papers in International Journals and has participated in presentations of more than 180 papers in national and international conferences. He is editor of the Elsevier journal Operations Research Perspectives (ORP) and co-editor of the JCR-listed journal European Journal of Industrial Engineering (EJIE). He is also an associate editor of other important journals like TOP and Applied Mathematics and Computation as well as a member of the editorial boards of several journals, most notably European Journal of Operational Research and Computers and Operations Research. He is the director of the Applied Optimization Systems Group (SOA) at the Instituto Tecnológico de Informática (ITI) where he is or has been the principal investigator in several public research projects as well as privately funded projects with industrial companies. His research interests include scheduling and routing in real-life scenarios.



In this talk, we demonstrate that it is not enough with having groundbreaking research in order to have a high-quality paper published. More often than not, we find that papers are not properly written and ideas are not adequately put on paper. Doing good science is not necessarily correlated with writing good papers. However, the task of writing good papers is often relegated and is not actively learned in Ph.D. programs. Furthermore, there is the issue of knowing all the little details and quirks of the editorial system. The talk goes into detail about the writing process, studying how each part of the paper should be written, with particular attention to papers written in the operations research/management science area. Title, abstract, introduction, methods, results, and references are covered in detail. Later, we analyze the process from journal selection, submission, and peer review, including how to cope with the referee's comments. At the end of the talk, we give useful hints coming from the experience of the editorial work of the speaker.
The contents of the talk are equally interesting to both newcomers to scientific writing as well as to experienced researchers which might find valuable advice at some parts of the process.

 Prof. Gen

Short Biography:

Mitsuo Gen received his PhD in Engineering from Kogakuin University, PhD degree in Informatics from Kyoto University and is Senior Research Scientist at FLSI and Visiting Prof. at TUS. He was faculties at Ashikaga Institute of Technology for 1974-2003, at Waseda University for 2003-2010. He was visiting faculties at University of California at Berkeley for 1999.8-2000.3, Texas A&M University for 2000.1-3 & 2000.8-9, Hanyang University in S. Korea for 2010-2012 and National Tsing Hua University in Taiwan for 2012-2014. His research field is Evolutionary Computation, Manufacturing Scheduling and Logistics Systems. He is coauthor of the following books: Genetic Algorithms and Engineering Design, 1997 and Genetic Algorithms and Engineering Optimization, 2000, John Wiley & Sons, New York; Network Models and Optimization: Multiobjective Genetic Algorithm Approach, 2008 and Introduction to Evolutionary Algorithms, 2010, Springer, London.


In the real-world of scheduling systems, there are many combinatorial optimization problems (COPs) imposing on more complex structure, nonlinear constraints, and multiple objectives. The COPs make the problem intractable to the traditional approaches because of NP-hard ones. Flexible Jobshop Scheduling Problem (FJSP) is a generalization of the jobshop and parallel machine environment, which provides a closer real manufacturing systems.

In order to develop an efficient algorithm whose reasonable computational time for NP-hard COPs, we have to consider 1) quality of solution, 2) computational time and 3) effectiveness of the nondominated solutions for multiobjective COP. As a subset of metaheuristics, Evolutionary Algorithm (EA) is a generic population-based metaheuristic such as Genetic Algorithm (GA), Particle Swarm Optimization (PSO), and Estimation of Distribution Algorithm (EDA). EA is a very powerful and broadly applicable stochastic search and optimization technique which is effective for solving various NP hard problems.

In this keynote talk, we will summarize the real-world manufacturing scheduling models based on FJSP and a variant of hybrid EA algorithms for solving FJSP, fuzzy-FJSP and large scale FJSP. For expanding GA to hybrid metaheuristics, a sequent of the advanced developments will be introduced such as hybrid GA with PSO and Cauchy distribution for a fuzzy FJSP (IEEE Trans. Semicon. Auto., 2018) and hybrid cooperative co-evolutionary algorithm for a large-scale FJSP (IEEE Trans. Fuzzy Systems, 2019).

In the present work, we study the problem of optimal management of defined contribution pension funds, during the distribution phase, under the effect of inflation, mortality, and model uncertainty. More precisely, we consider a class of employees, who, at the time of retirement, enter a life assurance contract with the same insurance firm. The fund manager of the firm collects the entry fees to a portfolio savings account and this wealth is to be invested optimally in a Black-Scholes type financial market. As such schemes usually last for many years, we extend our framework, by: (i) augmenting the financial market with an inflation-adjusted bond, and (ii) taking into account mortality of the fund members.  Model uncertainty aspects are introduced as the fund manager does not fully trust the model he/she faces. By resorting to robust control and dynamic programming techniques, we provide: (a) closed-form solutions for the case of the exponential utility function, (b) a detailed numerical study of the qualitative features of the problem at hand that elucidates the effect of robustness and inflation on the optimal investment decisions.

1- Data access on various digital platforms, is changing the nature of Information Systems (IS) research. These research studies often characterized by the use large datasets, comprising of structured and unstructured data, from various platforms. The questions that such studies address, in turn, may attempt to use methods from computational science like sentiment mining, text mining, network science and image analytics to derive insights. However, there is often a criticism of weak theoretical contribution in many of these studies, due to a lack of generalizable findings. We provide directions to contribute back to the IS discipline, whereby findings can explain more about the phenomenon surrounding the interaction of people with technology artefacts and the ecosystem. Our directions attempt to address this gap in extant literature and provide insights on the methodological adaptations required in “big data studies” to be converted into “IS research” and contribute to theory building for the nomological network.

2- Most researchers fail to make an impact in publishing in a reputed journal because of fundamental shortcomings of their study and how they have developed it. As an editor, these shortcomings are somewhat generalizable, and applies to many manuscripts which are mostly desk rejected. An editorial perspective would be shared surrounding how to carve out an impactful research for management scholars who would want to publish their findings in top platforms for research dissemination.

As environmental and social obligations are a critical focal point in today’s industrial sector, a supply chain formed on sustainable platforms enables more collaboration prospects.  Sustainability in all aspects boosts the professional image and helps it gain competitive advantages. Sustainable techniques and resources also assist to increase the efficiency of buildings, vehicles, machinery and man-power, resulting in significant cost savings. Because of the complexities in the real-world supply chain problems, uncertainty is a significant factor to consider.  Further, due to the several goals of company(ies), multiple objectives or multiple attributes need to be chosen in a supply chain problem. Therefore, multi-objective or multi-attribute decision making problems play a vital role in supply chain management problems.
