A heuristic method for optimum redundancy allocation in non-coherent systems
Abstract This paper presents a heuristic method for optimum redundancy allocation in non-coherent systems. The method uses two forms of redundancy, namely parallel and series forms. System reliability of non-coherent systems cannot be generally improved by using only parallel redundancy. So use of series or parallel redundancy, whichever gives better system reliability, is recommended. The proposed method retains all the advantages of the most recommended [2,4,5] heuristic reliability optimization techniques. The method is general and can be used with linear or non-linear, separable or non-separable constraints.
