Aircraft designers strive to achieve optimal weight-reliability tradeoffs while designing an aircraft. Since aircraft wing skins account for more than fifty percent of their structural weight, aircraft wings must be designed with utmost care and attention in…

Generally fuzzy control system (FCS) is worked in washing machine. For the fuzzy set theory , membership functions are the building blocks. In a fuzzy set , fuzziness is determined by its membership functions. The shapes of membership functions are important…

The main objective of this paper is to propose a new hybrid algorithm for solving the Bi objective green vehicle routing problem (BGVRP) from the BicriterionAnt metaheuristic. The methodology used is subdivided as follows: first, we introduce data from the GV…

A multi-objective linear programming problem is made from fuzzy linear programming problem. It is due the fact that it is used fuzzy programming method during the solution. The Multi objective linear programming problem can be converted into the single object…

The main purpose of this paper is to build a new approach for solving a fuzzy linear multi-criterion problem by defining a function called “error function”. For this end, the concept of level set is used to construct the error function. In addition, we introd…

In this paper, the statistical averaging method and the new statistical averag ing methods have been used to solve the fuzzy multi-objective linear pro gramming problems. These methods have been applied to form a single objective function from the fuzzy multi…
