求解,具有实际意义.
本文采用优选法的分批试验法,对文献[8]的算法作了进一步的简化,从而提出一个更简
捷的算法.文中举例说明这种算法的应用,并和文献结果进行了比较.
Abstract:
The optimization problem for system reliability with redundancy is essentially
nonliear integer programming. For solving this kind of problems, the existing exact
and approximate methods require a considerable amount of computation time. Consequently,
simpler heuristic methods attract one's attention.
It is pointed in this paper that solving reliability optimization problems by direct
optimization technique might be worth to be considered. By suitably relaxing the
engineering constraints it is possible and practical to simplify the solution of reliability
optimization problems.
Using the technique of batch test, the algorithm in [8] is further simplified, and
a rapid heuristic algorithm for optimal redundancy allocation is presented. Applications
to this algorithm were illustrated by two examples, and compared with other reference.
