Now days, internal combustion engines are used in most of the automobiles and mechanical machineries. The piston is a part without which no internal combustion engine can work i.e., piston plays a vital role in almost all types of vehicles. So, the reliability of piston manufacturing system is most essential for the proper functioning of vehicles. In this paper, fault tree method is used to analyze the reliability of piston manufacturing system. Also, risk reduction worth is adopted as a measure of importance for identifying the crucial element that has significant impact on the reliability.
Keywords: reliability, piston manufacturing system, fault tree analysis 1. Introduction
Several researchers have used fault tree analysis (FTA) method to analyze the vast majority of industrial system reliability problems. FTA is a deductive failure analysis which focuses on one particular undesired event and which provides a method for determining cause of this event [1]. Factors that contribute to the events are traced to the smallest sub-divisions termed as basic events. The cascading effects of several sub-systems may be linked together and multiple effects may be captured through logical AND and OR relationships. Head event probability is determined from basic events in the fault tree. Tanaka and Fan [2] presented the approach based on a fuzzy fault tree model and determined the maximum possibility of system failure from the possibility of failure of each component within the system according to the extension principle. Hessian et al. [3] discussed FTA for system design, development, modification, and verification.
