Abstract

Reliability analysis of infrastructure such as water main systems has become a vital need for engineers and decision makers to have an accurate prediction of service life of the system and assessing the factors that are affecting it most. In this paper, Monte Carlo simulation method will be used for reliability analysis and service life prediction of a pipeline system. As an extension to the previous works, two limit state functions are considered. It will be shown that how different individual failure modes affect the probability of system failure.

Sensitivity analysis is also carried out to show the effect of changing basic variables on the reliability and service life of the system. It will be concluded that the applied methodology can consider different failure modes for estimating service life of the system and it can also provide a reliable guide for rehabilitation and maintenance plans. In addition, the results of the system reliability analysis in this study can be useful for designing more reliable new pipeline systems.
