Problem statement: The purpose of this study was to compute fuzzy reliability and fuzzy availability of the serial process in butter-oil processing plant for various choices of failure and repair rates of sub-system.This plant consists of eight sub-systems out of which two are supported by standby units with perfect switch over devices and considered that these two sub-systems never fail.The effect of coverage factor on the fuzzy availability also studied.Approach: In this study the chapman-Kolmogorov differential equations were formed using mnemonic rule from the transition diagram of the butter-oil processing plant.These equations were solved for steady state recursively and results were obtained by computer program.Results: Result in the study analyzed fuzzy availability for various values of system coverage factor, failure and repair rates.Industrial implications of the results also briefly discussed.Conclusion: The findings in the study suggested that the management of butteroil processing plant's sensitive sub-system is important to improve its performance.
