Reliability optimization in cable system design using a fuzzy uniform-cost algorithm

Reliability optimization methods for computer-aided design of a rapid-transit-system transmission line, previously proposed by the authors (1981), were useful for simple systems with a small number of sections. There is a combinatorial explosion in the time complexity for the computation of the configuration vector and the solution runs into difficulty very quickly with an increased number of sections. Use is made of a fuzzy optimization algorithm. This aspect is addressed here so that a more general problem can be solved. The strategy is to divide the system into smaller blocks and find solution sets for the smaller blocks using an efficient search strategy, which are then searched for an overall minimal solution
