考虑批量生产的设备视情维护策略优化研究

针对目前市场环境对批量生产中的交付时间、产品质量以及企业信誉愈发看重的情况,提出了考虑三者联合的设备维修策略.首先,在已知产品质量和设备劣化状态存在一定函数关系的情况下,将其衍生至次品率上并将单位周期生产结束后的设备状态与生产时间相结合,进行预防性维护和设备更换的维修方式选择.其次,根据时间阈值和预防性维护阈值,以经济...

Optimization of equipment condition-based maintenance strategy considering batch production

In view of the increasing emphasis of the current market environment on the delivery time, product quality and enterprise reputation in mass production, an equipment maintenance strategy considering the interaction among these three factors was proposed. First of all, if product quality and equipment deterioration state were known to have a certain functional relationship, it was derived to the defective rate, and the equipment state after the end of the unit cycle was combined with the production time to choose the maintenance mode of preventive maintenance and equipment replacement. Then, according to the time threshold and the preventive maintenance threshold, the optimal economic benefit was taken as the final objective to establish the total maintenance cost model in consideration of batch production. Aiming at the proposed optimization model, the Monte Carlo simulation method and the central combination design method in response surface analysis were combined to solve the model. Finally, the effectiveness and reliability of the model were proved by a computing example.
