Abstract (in Japanese) (See Japanese page) 
(in English) One of the most significant problems in reliability theory is an optimal arrangement problem on the assumption that component reliabilities are given. The problem involves finding a component arrangement to maximize system reliability, namely, the optimal arrangement. It is useful to obtain the optimal arrangement when we design a practical system. In this paper, we develop an algorithm for efficiently finding the optimal arrangement of a connected-(r,s)-out-of-(m,n): F lattice system based on the depth-first branch-and-bound method. We evaluate the performance of the algorithm with the derived conditions by performing numerical experiments.
