Supplier selection and allocating orders to supplier is a complex multi objective problem which includes both quantitative and qualitative factors. In order to achieve an efficient solution in the quantitative factors, a Multi Objective Fuzzy Linear Programming [MOFLP] model with fuzziness in objective, resources, technological coefficient and resources for the proposed weighted additive model ...

This paper brings together results which are required in order to extend the global games approach to settings where the game structure is endogenous. More precisely, it shows that the selection argument of Carlsson and van Damme [2] holds uniformly over appropriately controlled families of games. Those results also give proper justification for the inversion of limits which is often implicit i...

Multiple-input multiple-output (MIMO) systems are anticipated to be widely employed to address the ever increasing capacity demands for wireless communication systems. MIMO technology is one solution to attain this by transmitting multiple data streams from multiple antennas. Increasing the number of transmit and receive antennas enables to improve system performance , but the multiple RF chain...

 Simulation and optimization are two arguably most used operations research (OR) tools. Optimization intends to choose the best element from some set of available alternatives. Stochastic simulation is a powerful modeling and software tool for analyzing modern complex systems. This capability complements the inherent limitation of traditional optimization, so the combining use of simulation an...

nitrogen is produced mainly from its most abundant source, the air, using three processes: membrane, pressure swing adsorption (psa) and cryogenic. the most common method for evaluating a process is using the selection diagrams based on feasibility studies. since the selection diagrams are presented by different companies, they are biased, and provide unsimilar and even controversial results. i...
