Abstract

Among all systems, the series system is having the lowest optimal replacement time, while the parallel system is having the greatest optimal replacement time. This paper is comparing the standard age replacement strategy (SARS) with two newly introduced strategies (strategies A and B) for some multi-unit systems, so as to investigate the advantages of each of the three strategies (SARS, strategy A and strategy B). For simple illustration of the proposed replacement cost models under SARS, strategy A and strategy B, two numerical examples were provided, and the results obtained will be important to engineers, maintenance managers and plant management, in selecting and applying the best strategy for preventive maintenance of a particular multi-unit system.
