Abstract

Growing concern about the increasing number of disasters, safety is the main criterion to design every system. In this paper a complex bridge system is considered which includes five independent components whose longevity follows modified Weibull distribution function. The main aim of this paper is to enhance the system reliability by reduction method, warm duplication method and cold duplication method. In each method four sets of components are considered for improvement and their reliability functions reformulated. The three methods are compared with a numerical example.
