Original Equipment Manufacturers (OEM) that assemble multiple durable products are actively engaged in adopting remanufacturing practices. This study addresses the introduction of a new business proposal, which is carrying out remanufacturing of components from acquired returns by an OEM through the set-up of required Reverse Flow Capacities (RFC), which are capacities for dismantling the returns and capacities for remanufacturing various components. Hence, by incorporating the activity on remanufacturing of components, an OEM creates a new cheaper source for obtaining components, in addition to the conventional sources of manufacturing and/or purchasing. The components obtained from any of these three sources can be used to assemble the multiple durable products for satisfying demands. The study refers to this problem as “Multi Products–Component Remanufacturing (MP-CR) problem”. Furthermore, it is identified that the incorporation of MP-CR problem has tremendous potential in the Indian automobile sector. With these, this study address two strategic issues and an operation issue for the incorporation of new MP-CR problem to an OEM. The first strategic issue is the determination of RFC that must be set-up. This strategic issue is addressed in synchronize with the operational issue of determining the optimal Inventory & Production Plans (I&PP) for assembling multiple products for a given planning horizon. In addition, once the optimal RFC is determined, the second strategic issue is the determination of optimal period (called as Breakeven Period (BEP)), after which the OEM would reclaim the capital investment for setting-up the optimal RFC. In order to address these three interrelated decisions, a systematic methodology is proposed. In the proposed methodology, first an Integer Linear Programming Model is developed for the existing system of the OEM to determine the optimal I&PP. Next, this model is extended to determine the optimal RFC and corresponding optimal I&PP. The solution from both proposed models are used for obtaining the Breakeven Period (BEP), which indicates when the capital investments breakeven. Finally, the proposed methodology is demonstrated by developing suitable data observed from an Indian Automobile OEM.

确定OEM的多产品组件再制造问题的最佳反向流量和盈亏平衡期的方法

组装多种耐用产品的原始设备制造商（OEM）积极参与采用再制造实践。这项研究解决了引入新业务建议的问题，该建议正在通过OEM所需要的逆向流动能力（RFC）的设置来对OEM所获得的退货进行组件的再制造，这是用于退货的能力和再制造各种能力。组件。因此，除了传统的制造和/或采购来源外，通过合并零部件再制造活动，OEM为制造零部件创造了新的更便宜的来源。从这三种来源中的任何一种获得的组件均可用于组装多种耐用产品，以满足需求。该研究将该问题称为“多产品-组件再制造（MP-CR）问题”。此外，可以确定的是，MP-CR问题的合并在印度汽车领域具有巨大潜力。利用这些，本研究解决了将新的MP-CR问题并入OEM的两个战略问题和一个运营问题。第一个战略问题是确定必须建立的RFC。该战略问题与确定最佳库存和生产计划（I＆PP）的运营问题同步进行，以针对给定的计划范围组装多种产品。此外，一旦确定了最佳RFC，第二个战略问题就是确定最佳期限（称为盈亏平衡期（BEP）），之后，OEM会收回建立最佳RFC的资本投资。为了解决这三个相互关联的决定，提出了一种系统的方法。在提出的方法中，首先为OEM的现有系统开发了整数线性规划模型，以确定最佳的I＆PP。接下来，扩展该模型以确定最佳RFC和相应的最佳I＆PP。两种提议模型的解决方案都用于获得盈亏平衡期（BEP），该盈余表明了资本投资何时达到盈亏平衡。最后，通过开发从印度汽车OEM处观察到的合适数据来证明所提出的方法。首先，为OEM的现有系统开发一个整数线性规划模型，以确定最佳的I＆PP。接下来，扩展该模型以确定最佳RFC和相应的最佳I＆PP。两种提议模型的解决方案都用于获得盈亏平衡期（BEP），该盈余表明了资本投资何时达到盈亏平衡。最后，通过开发从印度汽车OEM处观察到的合适数据来证明所提出的方法。首先，为OEM的现有系统开发一个整数线性规划模型，以确定最佳的I＆PP。接下来，扩展该模型以确定最佳RFC和相应的最佳I＆PP。两种提议模型的解决方案都用于获得盈亏平衡期（BEP），该盈余表明了资本投资何时达到盈亏平衡。最后，通过开发从印度汽车OEM处观察到的合适数据来证明所提出的方法。
