本研究的目的是进行比较评估的四个决策方法，涉及到考虑环境和经济方面的洗衣机的寿命结束阶段，并建议优先回收和生态设计的洗衣机。选择的四种方法是：二维图，生态效率，货币方法和多属性决策（MADM）。生命周期评估（LCA）被用来量化的环境方面的组件在一个定义的产品系统，和销售价格以及与处置的组件相关的成本被认为是其经济方面的评价。二维图、货币方法和多属性决策都显示了类似的结果。然而，生态效率方法的结果却大不相同。当在部件的寿命终止阶段做出考虑环境和经济因素的决策时，建议同时使用所有这四种方法，因为所有四种方法都有各自的优缺点。通过同时应用几种方法，决策者可以更好地做出选择环保和经济高效部件的决策。
The objective of this study was to carry out comparative evaluation of four decision-making methods that involves consideration of both environmental and economic aspects in the end-of-life stage of a washing machine, and to suggest priorities for recycling and ecodesign of the washing machine. The four methods chosen were: two-dimensional diagram, eco-efficiency, monetary method and multi-attribute decision-making (MADM). A life cycle assessment (LCA) was used to quantify the environmental aspects of components in a defined product system, and sales prices as well as costs associated with the disposal of the components were considered for the evaluation of their economic aspects. The two-dimensional diagram, the monetary method and the MADM all showed similar results. However, the results of the eco-efficiency method were quite different. When making decisions that consider both environmental and economic aspects of a component in its end-of-life stage, it is recommended to use all these four methods concurrently because all four methods have their own pros and cons. By applying several methods simultaneously, decision makers are in a better position to make decisions about choosing components that are environmentally friendly and economically efficient.
