Optimal Allocation of Complex Equipment System Maintainability

Abstract

The maintainability allocation of equipment system is a multi-objective programming problem with multiple constraints. Based on the defects of traditional algorithm, it is difficult to conquer all the constraints at the same time, and it is difficult for the result to reflect different satisfaction levels on the targets. This paper proposes a method in combination with genetic algorithm (GA) and satisfaction function. Firstly, use GA to solve the optimal solution of the single target; secondly, get the satisfaction level of the total target through that of the single target; finally, obtain satisfactory solution of the problem with GA. Results show that the method can effectively solve the defects above, which is significant to the optimal allocation of equipment system maintainability.
