Maintenance, reliability and performance optimization for remanufacturing and sustainability

这项研究计划建议调查再制造、更新或二手物品的维护、可靠性和性能优化问题。再制造，即通过拆卸、清洁、修理和更换部件以及重新组装，将使用过的或报废/报废的产品恢复到类似新的状态的过程，已被证明对制造商和消费者都具有经济和环境吸引力。再制造的可行性在很大程度上取决于退回产品的数量和质量。这些退回产品的退化状况和状态影响从这些产品中拆卸回收的部件的可靠性和成品率。在再制造过程中使用这些部件还需要升级和翻新活动，这可能会增加所生产的再制造二手产品的成本。此外，制造商倾向于提供慷慨的保修范围，以吸引消费者。所有这些物流、生产、销售和支持决策对环境和成本的影响都很大，因此需要开发数学模型来分析这些问题，并在再制造商和消费者的决策过程中告知他们。

This research program proposes to investigate the maintenance, reliability and performance optimization issues for remanufactured, refreshed or second-hand items. Remanufacturing, the process of restoring used or end-of-life/end-of-use products to like-new conditions by disassembly, cleaning, repairing and replacing parts, and reassembly, has proven to be attractive economically and environmentally for both manufacturers and consumers. The viability of remanufacturing is heavily conditioned by the quantity and quality of the returned products. The condition and state of degradation of these returned products affect the reliability and yield rates of the components recovered by disassembly from these products. Using these parts in the remanufacturing process also requires upgrading activities and reconditioning that can increase the cost of the remanufactured second-hand products produced. Moreover, manufacturers tend to offer generous warranty coverage in order to attract consumers. The environmental and cost implications of all these logistics, production, sales and support decisions are high and therefore require the development of mathematical models to analyze these problems and inform remanufacturers and the consumer in their decision-making process.
