This research represents a comprehensive exploration of optimization policies pertaining to burn-in, quality control, and preventive maintenance for light-emitting devices. Utilizing a MATLAB-based computational model, we embarked on an in-depth investigation of the complex interplay and dependencies between these policies. Our findings illustrated that, with optimal burn-in time, cut-off threshold, and replacement interval, the total cost per usage duration was significantly reduced. Additionally, we investigated the system performance with and without quality control. It was observed that an increase in burn-in time corresponded to an increase in cost. The absence of quality control resulted in a similar pattern with the replacement period, where the cost remained constant after a certain replacement period. Conversely, the implementation of quality control indicated a direct relationship between burn-in time and cost, and an inverse relationship between replacement period and cost.
