A STRUCTURED FRAMEWORK FOR RELIABILITY AND RISK EVALUATION IN THE MILK PROCESS INDUSTRY UNDER FUZZY ENVIRONMENT

This paper aims at proposing a novel integrated framework for studying reliability and risk issues of the curd unit in milk process industry under uncertain environment. The considered plant’s complex series-parallel configuration was presented using Petri Net (PN) modeling. Fuzzy Lambda-Tau (?-?) approach applied to study analyze aspects plant. Failure dynamics has been analyzed with respect increasing/ decreasing trends tabulated indices. Availability plant shows trend an increase spread values. For improving system’s availability, analysis done identify most critical failure causes. Using traditional FMEA approach, sheet generated on basis expert’s knowledge/experience. Fuzzy-Complex Proportional Assessment (FCOPRAS) within identification causes associated different subsystem/components In order check consistency ranking results, Technique Order Preference by Similarity Ideal Solution (FTOPSIS) FCOPRAS approach. Ranking results are compared checking robustness related decision making which would be useful designing finest maintenance schedule unit. Overheating/moisture lead winding (MSCP5), visible sediment jam filter (MBFP3), improper quality oil (H4), blade breakage (CTK4), wearing gears (PFM11), cylinder leakage (CFM7) were recognized as contributing system unavailability. supplied manager framing suitable time-based intervals policy
