| Popis: | 100 With a high demand of notebook computers in recent years, a bulk of wastes will be generated in the next few years accordingly.Notebook computer wastes contain not only valuable materials and parts, but also hazardous substances as well. Due to the environmental impact of these wastes, effective management such as reusing, remanufacturing, and recycling, is an essential issue for the participants in the supply chain and life cycle. The objective of this research is to develop a mathematicalmodel to determine the optimal handling of used notebook computersin order to obtain the optimal profit by considering reusing, remanufacturing, and recycling handling methods based on the current Taiwan system. The system consists of part supplier, manufacturer, government, collection site, reuser site, remanufacturer, and recycler. The study deals with the flows of material and cash in the model. The result shows that the optimal profit is obtained by sending all the used products to the reuser site. Then, some tests are presented to understand the effect of parameters on the total profit of system, such as returned product percentage, used product price, used part price,Advanced Recycling Fee, and number of used partsrecycled. In addition, this study applies the concept of Switzerland waste handling to the Taiwan system. We find that the Taiwan system can hold higher product return rate than Switzerland system; however, when the product return rate keep increasing, both systems cannot hold and need to modify. We believe that the results of this study can serve as a reference for the policy-making with used products handling and subsidy. |
