In this paper, based on bifuzzy theory, we study the multiobjective programming problem under bifuzzy environment and present the expected value model to the problem. Furthermore, to the proposed model, the concepts of non-inferior solution are defined, and their relations are also discussed. According to practical decision-making process, a solution method, called the method of main objective ...

Aged earthworks constitute a major proportion of European rail infrastructures, the replacement and remediation which poses serious problem. Considering scale networks involved, it is infeasible both in terms track downtime money to replace all these assets. It is, therefore, imperative develop rational means managing slope infrastructure determine best use available resources plan maintenance ...

The rapid development science technology fierce market have made importance performance management increasingly prominent in corporate management. purpose to explore deal with some effects various factors on employee tap potential employees, improve performance, also bring qualitative leap organization. improvem...

Design, implementation and operation of solar thermal electricity plants are no more an academic task, rather they have become a necessity. In this paper, we work with power industries to formulate a multiobjective optimization model and attempt to solve the resulting problem using classical as well as evolutionary optimization techniques. On a set of four objectives having complex trade-offs, ...

Scalarization approaches to purposely generating epsilon-efficient solutions of multiobjective programs are investigated and a generic procedure for computing these solutions is proposed and illustrated with an example. Real-life decision making situations in which the solutions are of significance are described.
