Abstract:

This paper statistically establishes the feasibility of using Simulated Annealing as compared to traditional method for the wide range of deteriorating systems and hence presents a Simulated Annealing assisted hybrid tool to determine optimal PM schedule for maximizing availability of deteriorating systems. The proposed method carries out initially the Weibull analysis on the failure data collected, checks for feasibility of PM and if PM is found feasible it searches for global optimal schedule for PM using SA. The results obtained from SA are statistically compared with those obtained using traditional method (Integrated Graphical model) using inferential statistics. As the findings are quite encouraging, the proposed hybrid tool can be conveniently used for deciding PM strategy.
