法律约束情形下电子产品回收再制造研究

E-product remanufacturing under product take-back regulation

面对政府制定的法律约束,企业需对旧产品进行回收处理.传统文献虽然考虑了法律约束的情形,但很少将其量化到模型中.基于此,将政府制定的最小回收率作为约束条件处理,并将回收率作为决策变量,分析回收率约束对企业实施回收再制造的影响.研究表明,当旧产品逆向运营成本取极端值时,在法律约束情形下,制造商要么选择回收所有旧产品,要么选择政府制定的最小回收率.然而,当逆向运营成本取值不那么极端时,制造商的最优决策由逆向运营成本与新产品生产成本的组合决定.此外,以苹果公司为案例背景,依据现实数据对模型进行验证,实例分析表明模型具有较强的稳健性与实用性.

The manufacturer should be involved in the collection of used products under product take-back regulation issued by the government. Research on environmental regulation is not uncommon, but with collection rate constraint consideration has received limited attention. Therefore, we use the collection rate as a decision variable and analyze the effect of constraint on the remanufacturing strategies. Research results show that the manufacturer adopts the maximum（minimum） collection rate when the inverse operating cost falls on the two opposite ends of the spectrum. Otherwise,combinations of inverse operating cost and new product manufacturing cost lead to the optimal solutions. In addition, we use Apple company as the case to verify the proposed model through real data. Numerical results show the robustness and applicability of the proposed model.
