Bio: Jiawei Zhang is an Associate Professor of Operations Management and Harold MacDowell Faculty Fellow at the Stern School of Business, New York University. He received a B.S. degree in Applied Mathematics and an M.S. degree in Operations Research from Tsinghua University, and a Ph.D. in Operations Research from Stanford University. His research interests include mathematical programming and ...

Operations Research present state and future trends are analyzed from the Fuzzy-Sets-based methodologies point of view. Then, in a more particular perspective, some specific topics of Fuzzy-Sets-based models in Operations Research, such as fuzzy optimization, preference modelling, linguistic modelling and decision models, as well as some other well known Operations Research specific topics, are...

We examine our progress in scheduling remanufacturing operations by reviewing the literature in detail. We individually examine published research in scheduling disassembly, remanufacturing/repair, and reassembly operations and their integration. The objective functions/performance criteria, quantitative methodologies, and complexities/issues are examined. Finally, an overall assessment of our ...

Twente. Beta is the largest research centre in the Netherlands in the field of operations management in technology-intensive environments. The mission of Beta is to carry out fundamental and applied research on the analysis, design, and control of operational processes.

Practitioners of Operations Research (OR) traditionally concentrate on mathematical and computational aspects of quantitative models, sometimes resulting in risky implementation or early model obsolescence. We propose an approach, inspired by system concepts and technology management, which includes softer influences, such as decision frequency, model life cycle and technological stage of manag...

This paper presents an approach to model-based diagnosis that rst compiles a rst-order system description to a propositional representation, and then solves the diagnostic problem as a linear programming instance. Relevance reasoning is employed to isolate parts of the system that are related to certain observation types and to economically instantiate the theory, while methods from operations ...

The special issue of Business Systems Research (SI of BSR) is co-published by the Slovenian Society INFORMATIKA – Section for Operational Research (SSI – SOR) and contains developments and new techniques in operations research (OR) models and their practical uses in various fields of business and economics. Seven papers that investigate developments and new techniques in operations research (OR...

We consider student use and perception of video tutorials that were produced to serve as virtual office hours for an undergraduate Operations Research (OR) course. The video tutorials complemented the traditional classroom experience by offering different example applications, presentations of solution methods, and examples for different cases of an OR problem (e.g., maximize versus minimize ob...

Human beings are critical to the functioning of the vast majority of operating systems, influencing both the way these systems work and how they perform. Yet most formal analytical models of operations assume that the people who participate in operating systems are fully rational or at least can be induced to behave rationally. Many other disciplines, including economics, finance, and marketing...
