ObjectivesThe main objective of IJOR is to promote research and application of operations research theory and application in new economy and society. IJOR aims to help professionals working in the field of operations research, academic educators, industry consultants, and practitioners to contribute, to disseminate and to learn from each other’s work. The global dimension is emphasised in developing operational research theory and applications to meet the accelerating technological changes and changes in global economy. IJOR aims to act as a forum for exchanging innovative ideas and sharing practical experiences in teaching and learning of operations research theory, models and applications.ReadershipIJOR is a forum to help professionals, academics, researchers and practitioners, working in the field of operations research theory and applications in the emerging economy and society, to discuss of important ideas, concepts and disseminate information and to learn from each other's work.ContentsIJOR publishes original papers, review papers, technical notes, and book reviews. Special Issues devoted to important topics in operational research will occasionally be published. The applications of operations research techniques such as forecasting, investment, location, logistics, maintenance, marketing, purchasing, production, inventory, project management, reliability and scheduling are welcome. Articles that deal with finance, government, health services, manufacturing, education, energy, mining, sports, and transportation are encouraged. Computer applications in operations research theory and applications including decision support systems, AI and expert systems, heuristics, networks, mathematical programming, multi-criteria decision methods, problems structuring methods, queues, and simulation would be suitable for IJOR.
