摘要

再製造已被證實，除了可以節省40%至60%的成本外，其生產只使用約20%的能源，因此再製造是公認可以能減少大量的浪費，有效改善環境問題的方法之一。
再製造生產流程會受到製程中某些不確定因素的影響，使得整體製造成本增加，這也引發了本研究之動機。本研究以電腦周邊產品為例，探討回收品供需及品質隨機的情況下，利用兩階段隨機規劃之數學模式建構最佳收購及產能模式，且針對不確定性對決策與績效指標的影響進行討論。對電腦周邊產品再製造時之回收品品質、生產成本、利潤進行分析及探討後得知，需求與供應的隨機會對再製造系統的成本及利潤造成影響，不同產品不同的回收品品質亦會影響生產者的決策。相信本研究之成果可對於企業在未來實施再製造生產製程評估時之參考。

It has been confirmed that, in addition to save 40-60% of the cost, remanufacturing uses only about 20% of energy in its production, and therefore it can be recognized that remanufacturing can reduce lot of wastes and is one of effective methods to improve environmental problems.
There are several uncertainty factors occurred in the remanufacturing processes and they would result in an increase in the overall manufacturing cost, which motives our research. This study uses computer peripheral products as examples to explore the uncertainty of the supply and quality of cores with stochastic product demands. A mathematical model with two-stage stochastic programming is built for developing the optimal acquisition and production model. In addition, we will discuss the effect of uncertainty on remanufacturing decision-making and several performance indicators. According to the research results, it can be found that random demand and supply of computer peripheral products will affect re-manufacturing system cost and profit and different product quality of recycling materials will also affect the decision of producers. We believe that the results of this study can be a reference for those enterprises performing re-manufacturing production in the future.
