Performance Modeling and Analysis of Refrigeration System of a Milk Processing Plant using Petri Nets

Abstract

This paper described the performance modeling of the refrigeration system of a milk processing plant using Petri nets and obtained a quantitative analysis in terms of availability under varying operating parameters. For the modeling and simulation of the system, a Petri module of GRIF software was used. In the current study, an effort was made to use reliability, availability, and maintainability (RAM) tools, which can be quantitative or qualitative methods and software that reduce the uncertainties involved in random failures and consequent shutdowns of the plant. Finally, an attempt was made to provide a specific direction for determining maintenance strategies to meet operational objectives economically considering spare parts and repair facilities.
