FUZZY PROGRAMMING APPROACH FOR A COMPROMISE ALLOCATION OF REPAIRABLE COMPONENTS

The present paper, considered the allocation problem of repairable components for a parallel-series system as a multi-objective optimization problem for two different models. In the first model, the reliability of subsystems are considered as different objectives. While in the second model, the cost and time spent on repairing the components are considered as two different objectives. Selective maintenance operation is used to select the repairable components and a fuzzy programming algorithm is used to obtain compromise allocation of repairable components for the two models under some given constraints. A numerical example is also given to illustrate the procedure.
