Proposal for Obtaining Quisu-Optimal Arrangement of the 3-dimensional-consecutive-(r_1,r_2,r_3)-out-of-(n_1,n_2,n_3):F system

Abstract (in Japanese) (See Japanese page) 
(in English) In this study, we consider the component assignment problem of the 3-dimensional-consecutive-(r_1,r_2,r_3)-out-of- (n_1,n_2,n_3):F system. This problem generates all possible component assignments, evaluates system reliability under each component assignment, and then determines the optimal arrangement. However, when the number of components is large, this problem is going to be the combinatorial explosion problem, and thereby, it may fail to find the optimal arrangement within a reasonable time. Therefore, this study proposes obtaining method for quisi-optimal arrangement using Genetic Algorithm with an adding necessary condition. And, we show the results of optimal arrangement when n_1=r_1+1,n_2=r_2+1 and n_3=r_3+1.
