Based on the classical EPQ model, and considering the quality-contingent demand and periodic perfect preventive maintenance strategy, the decision model of economic production quantity is constructed with the goal of maximizing profit per unit time. In the construction of enterprise unit time profit model, the dynamic preventive maintenance cost, recovery cost, defective repair cost and product demand rate are constructed according to the actual problems of quality-contingent demand and equipment degradation. Due to the complexity of the objective function, this paper uses genetic algorithm to solve the model numerically, and verifies its rationality by comparing and analyzing EPQ decision-making without considering the quality-contingent demand.
