The redundancy allocation problem: a taxonomic literature review

Reliability, which can be described as the probability that a system operates on a continuous basis without failure for a pretedetermined mission time, is an important measure of system performance. Being parallel to the increasing complexity of systems, the results of the system's unreliability have become severe in terms of cost, effort, lives, etc., therefore the need for developing more reliable systems have become very important. In this content, reliability optimization problem is an important type of optimization problems because of its wide practical applications in real-world such as manufacturing systems, telecommunication systems, transportation systems and electrical power systems. In this study, a special type of reliability optimization problems which is called as the redundancy allocation problem is discussed, and a comprehensive literature survey in this field is presented based on a novel classification methodology. To analyze the latest trends in this area, the main focus is especially on papers which are presented in the last decade.
