摘要

In this article, a multi-state system with time redundancy where each system element has its own operation time is considered. In addition, the system total task must be performed during the restricted time. The reliability optimization problem is treated as finding the minimal cost system structure subject to the reliability constraint. A method for reliability optimization fOr systems with time redundancy is proposed. This method is based on the universal generating function technique for the reliability index computation and on genetic algorithm for the optimization. It provides a solution for the optimization problem fOr the complex series--parallel system and for the system with bridge topology. Two types of systems will illustrate the approach f systems with ordinary hot reserve and systems with work sharing between elements connected in parallel. Numerical examples are also given.
