The objectives of flood control, power generation, water supply and ecology for reservoir operation are neither completely coordinated nor opposed, its optimal decision-making is very complicated. This study proposed a method multi-objective optimization multi-attribute decision making (MODRO). correlation analysis was used to analyze the competitive relationship among extracted objectives, mod...

In this paper, a multi-objective method is used to optimize a heat recovery steam generator (HRSG). Two objective functions have been used in the optimization, which are irreversibility and HRSG equivalent volume. The former expresses the exergetic efficiency and the latter demonstrates the cost of the HRSG. Decision variables are geometric and operational parameters of the HRSG. The result...

Linear bilevel programming is a decision making problem with a two-level decentralized organization. The leader is in the upper level and the follower, in the lower level. This study addresses linear bilevel multi-objective multi-follower programming (LB-MOMFP) problem, a special case of linear bilevel programming problems with one leader and multiple followers where each decision maker has sev...

In practice, there are many problems which decision parameters are fuzzy numbers, and some kind of this problems are formulated as either possibilitic programming or multi-objective programming methods. In this paper, we consider a multi-objective programming problem with fuzzy data in constraints and introduce a new approach for solving these problems base on a combination of the multi-objecti...

Due to moving and transactions costs, most housing buyers do not routinely move in response to small changes in income or housing price. In this paper, the ‘‘own–rent,’’ ‘‘move– stay,’’ and length-of-stay decisions are modeled as multi-period optimization in the presence of transactions costs. The empirical section uses the American Housing Survey to provide a unique 12-year panel of household ...
