Abstract: In this paper, a redundancy optimisation problem, in which element lifetimes are fuzzy random variables (FRVs), is formulated by using fuzzy stochastic programming model. Subsequently, a new method is developed to solve the model based on the concepts of mean value of FRVs, chance-constrained programming and binary integer programming. Furthermore, an illustrative numerical example is also solved to clarify the methods discussed in this paper and major types of system performance are investigated.
