Abstract: The purpose of this paper is to deal with the simulation modelling and performance optimisation for the skim milk powder production system of a dairy plant using genetic algorithm (GA). This analysis is based on Markov birth-death process, the mathematical formulation of the system is carried out to derive first order Chapman-Kolmogorov differential equations by assuming that the failure and repair rate of each subsystem follows exponential distribution. The proposed method is used to compute long run availability using normalising condition, initial boundary conditions and recursive method. It provides the optimum system availability level for different combinations of failure and repair rates parameters of the subsystems of the skim milk powder production system of a dairy plant concerned. The results are presented and discussed with the plant personnel to adopt and practice suitable maintenance policies/strategies to enhance the productivity and quality of skim milk powder production system of the dairy plant.

Keywords: Markov process; Markov modelling; Chapman-Kolmogorov differential equations; long run availability; performance optimisation; skim milk powder production system.
