Availability Analysis and Performance Modeling of a Milk Pasteurization System using Petri Nets

Abstract

This paper presents the performance modeling of a refrigeration system in a milk processing plant using Petri nets, providing a quantitative analysis of availability across different operating parameters. The modeling and simulation were carried out using the Petri module of the GRIF software. In this study, an effort was made to apply Reliability, Availability, and Maintainability (RAM) tools, incorporating both quantitative and qualitative approaches to minimize uncertainties related to random failures and plant shutdowns. Additionally, the study seeks to offer guidance for developing cost-effective maintenance strategies, taking into account spare parts management and repair facilities to achieve operational goals.
