abstract soil nutrient management with efficient fertilizer use has an important role on maximizing yield and environmental effects. in this study game theory is applied to identify the nutrient proportion for corn production in kooshkak in fars province, iran, in 2008-2009. cost of fertilizer combinations and production of corn are the players of the game. a goal programming was applied to obt...

Here, we propose a mathematical model to analyze bimatrix game under entropy environment. In this new approach, the entropy function for each player are considered as objectives to the bimatrix game. This formulated model is named as Entropy Bimatrix Game Model which is a multi-objective non linear problem. To solve this kind of model, we have introduced a new solution technique, which determin...

this paper presents a framework for long term transmission expansion planning in competitive, electricity markets. transmission lines and phase shifters are taken into account as expansion options. maximization of the network users' benefits, with satisfying security constraints are considered as the criterion for transmission expansion planning. the elements of the objective function are the...

For many applications it is desirable to construct expert systems to be used as decision aids. It is often essential that the algorithm make decisions at least at the quality level of the best human experts according to some measure. The algorithm should not only incorporate human expertise and its related uncertainty, but also be able to exploit an opponent's uncertainty. In many instances, du...

this paper uses integrated data envelopment analysis (dea) models to rank all extreme and non-extreme efficient decision making units (dmus) and then applies integrated dea ranking method as a criterion to modify genetic algorithm (ga) for finding pareto optimal solutions of a multi objective programming (mop) problem. the researchers have used ranking method as a shortcut way to modify ga to d...

This paper proposes an improved approach to our previous work [11]. [11] uses Stackelberg game to model the interactions between electricity retailer and its customers and genetic algorithms are used to obtain the Stackelberg Equilibrium (SE). In this paper, we propose a bi-level programming model by considering benefits of the electricity retailer (utility company) and its customer. In the upp...

the problem of lot sizing, sequencing and scheduling multiple products in flow line production systems has been studied by several authors. almost all of the researches in this area assumed that setup times and costs are sequence –independent even though sequence dependent setups are common in practice. in this paper we present a new mixed integer non linear program (minlp) and a heuristic meth...
