Multiobjective Optimization for a Standby System by the Surrogate Worth Trade-off Method

Abstract

This paper deals with the multiobjective optimization problems for a standby redundancy system through the application of the Surrogate Worth Trade-off method. A multiobjective mathematical model is formulated and the problem considered is to optimize system reliability, cost weight and volume, for a given mission time, subject to multiple constraints. The preferred solution of the decision maker is obtained by using the Surrogate Worth Trade-off method. An illustrative numerical example is provided to indicate the efficiency of the proposed method.
