Simulation Modelling Practice and Theory Reliability–redundancy allocation problem with cold-standby redundancy strategy Mostafa Abouei Ardakan ⇑, Ali Zeinal Hamadani Department of Industrial and Systems Engineering, Isfahan University of Technology, 84156-83111 Isfahan, Iran a r t i c l e i n f o a b s t r a c t Article history: This paper considers the mixed integer non linear optimization of reliability redundancy Received 18 September 2013 allocation problem (RRAP) to determine simultaneous reliability and redundancy level of Received in revised form 10 December 2013 components. In the RRAP, it is necessary to create a trade off between component reliabil Accepted 15 December 2013 ities and the number of redundant components with the aim of maximizing system reli Available online 21 January 2014 ability through component reliability choices and component redundancy levels. RRAPs have been generally formulated by considering an active redundancy strategy. A large Keywords: number of solution methods have been developed to deal with these problems. In this Reliability optimization Reliability– paper, a cold standby strategy for redundant components is used, for the first time, to redundancy allocation problem Cold- standby redundancy strategy model the RRAP; a modified genetic algorithm is developed to solve the proposed non lin Genetic algorithm ear mixed integer problem; and three famous b
