Abstract:

The system degradation process was modeled by random coefficient regression model, in which the covariate was considered based on the accelerated failure time model, and the product quality was also considered in the model. The integrated cost model of condition-based maintenance and economic production quantity was proposed based on renewal reward theory. The optimal value of decision variables could be obtained by analyzing the integrated cost model. The optimal critical level of preventive maintenance and the optimal lot size were obtained by analysis of numerical case. Result shows that the optimal lot size decreases gradually with the increasing of covariate, but the optimal critical level of preventive maintenance does not change. Influence of optimal results caused by relevant parameter is explained by sensitive analysis.

Key words: degradation process    economic production quantity    accelerated failure time model    covariate    renewal reward theory
