SGER: Production Planning Models for Companies with Remanufacturing Capability

小行星9520438 本研究旨在解决产品在其生命周期结束时的再制造问题。这是一项旨在整合保护环境质量问题并同时保持经济制造的研究。特别是，该研究将寻求开发具有再制造能力的生产系统模型，该模型可用于探索不同需求模式、生产和处置成本以及政府行为对再制造政策经济可行性的影响。 再制造涉及翻新和/或部分重建从市场返回的产品，在其生命周期结束时，使其具有新产品的功能。这项研究是探索性的。要开发的模型的基本组成部分将包括产品分级、拆卸、分类、清洁、修理和组装。关于装配操作，假设手动装配。该模型还假设再制造和新装配在同一设施中同时进行。 该模型在充分开发后将用于确定最低成本采购和生产计划。该模型的输出将包括（1）要拆卸的产品数量，（2）要重复使用或处理的每个组件的数量，（3）要再制造的每个产品的数量，以及（4）为了满足市场需求而制造的新组件和每种类型产品的数量。 世界上许多地方日益认识到，由于对已达到其生命周期终点的产品处置不当而造成的环境退化问题。虽然拟议的研究不会消除这个问题，但它确实通过开发一种方法来将旧组件的重用集成到制造中来减轻影响。对环境的影响，资源的使用和保护，以及制造成本的节省，从研究可以是非常显着的。将开发的模型将为实现完整的模型铺平道路，这些模型可供公司用于评估将环境问题纳入制造决策和流程的成本和效益。

9520438 Uzsoy This research is aimed at addressing the problem of remanufacturing of a product at the end of its life cycle. It is a research that is aimed at integrating issues on preserving environmental quality and at same time maintain economic manufacturing. In particular, the research will pursue the development of a model of a production system with remanufacturing capability which can be used to explore the effects of different demand patterns, production and disposal costs, and government actions on the economic viability of remanufacturing policies. Remanufacturing involves the refurbishing and/or partially rebuilding a product returned from the market at the end of its life to give it the functionality of a new product. This research is exploratory in nature. The basic components of the model to be developed will include product staging, disassembly, sorting, cleaning, repair, and assembly. With respect to assembly operations, manual assembly is assumed. The model also assumes that both remanufacturing and new assemblies are carried out simultaneously in the same facility. When fully developed, the model will be used to determine a minimum cost procurement and production plan. Output from the model will include (1) the quantity of a product to disassemble, (2) the quantity of each component to reuse or dispose of, (3) the quantity of each product to remanufacture, and (4) the quantity of new components and products of each type to make in order to satisfy market demand. The problem of environmental degradation resulting from improper disposal of products that have reached the end of their life cycles is increasingly being recognized in many parts of the world. Whereas the proposed research will not eliminate the problem, it does, however, lessen the impact by developing a methodology to integrate the reuse of old components into manufacturing. The impact on environment, resource usage and conservation, and manufacturing cost savings to be derived from the research can be q uite significant. The models to be developed will pave the way for the realization of complete models that can be used by companies to evaluate the costs and benefits associated with integrating environmental concerns into manufacturing decisions and processes.
