摘要

This paper presents an integrated planning between the three core functions of shop floor management; main-tenance, production scheduling, and quality. The methodology is based on the conditional reliability of com-ponents and its effect on system operation. The objective is to minimize the system operation cost of the combined decision and investigate the cost-effectiveness of the integrated policy over the non-integrated plan-ning. The integrated approach helps the decision-maker to find maintenance actions for individual components, production schedule and sampling parameters for process quality inspection. Mathematical models for inte-gration and a flow chart for the combined methodology of the three functions are presented. Metaheuristic approaches, simulated annealing, and genetic algorithm are used for optimization. A simulation study at different levels of component degradation (service age) and schedule tightness factor is presented. Besides, we present an experimental analysis of varying model parameter values for the integrated planning and compare the results with the independent (non-integrated) planning approach. The results show the improved operational performance of the integrated planning and a lesser operating cost than the non-integrated planning. The pro-posed approach is dynamic as quality control parameters and production decisions will change as per the maintenance decision.
