In this paper, an idea of using space-time block coding (STBC) in multi-user cooperative diversity has been exploited to improve the performance of the transmission in wireless local area networks. The theoretical and simulation results show that, using STBC approaches can always achieve the better performance than existing techniques without introducing the space-time coding. By analyzing the ...

Large-scale projects often have several activities which are performed by subcontractors with limited multi-resources. Project scheduling with limited resources is one of the most famous problems in the research operations and optimization cases. The resource-constraint project scheduling problem (RCPSP) is a NP-hard problem in which the activities of a project must be scheduled to reduce the p...

many studies have been conducted to determine the efficiency of two-stage network structures in the recent years. the two-stage network with additional inputs to the second stage, in which the second stage is independent of the first stage are one of these structures. thus, there is a need for a model capable of calculating the efficiency of two-stage structures as well as efficiency of each st...

The concept of “oil to electricity” is crucial for expanding the share electricity in final energy consumption as well encouraging efficiency and emission reduction. Initially, a multidimensional strategy analysis conducted government, ports, ships concerned. From an economics perspective, mathematical model substitution benefit based on multiagent cooperative game theory under cap trade carbon...

This paper investigates advertising level, pricing and production quantity decision problems in a supply chain when demand and production cost disruptions occur simultaneously. The supply chain consists of one manufacturer and one retailer where customer demand depends on the retail price and advertisement expenditure. The authors examine this problem in two game-theoretic models: a cooperative...

in this paper, a new approach based on game theory has been proposed to multi responses problem optimization. game theory is a useful tool for decision making in the conflict of interests between intelligent players in order to select the best joint strategy for them through selecting the best joint desirability. present research uses the game theory approach via definition of each response as ...

Energy storage (ES) can be a good option to reduce power curtailment and increase the total profits of an integrated energy system. This article addresses sizing problem for ES renewable plants in wind-solar-storage system (IWSSS). A basic IWSSS model is first constructed analyze operation relationship among each part. nested game established study capacity problem. The outer layer non-cooperat...
