为研究我国废旧电子产品(WEEE)立法的问题,分析了供应商、制造商、零售商、需求市场及回收商的行为,分别建立了变分不等式模型,并在此基础上建立了五级再制造闭环供应链网络均衡模型.模型考虑了政府对于制造商的惩罚政策与对于回收商的补贴政策.通过修正投影算法求解算例,仿真分析了旧材料转化率、回收率、惩罚及补贴政策对闭环供应链网络均衡结果的影响.结果表明,随着政府对于回收商的补贴的增加,不但回收商的回收量提高,闭环供应链的新材料需求量、旧材料需求量、销售量均增加;相反,随着政府对于制造商未完成的回收量的罚款增加,回收量、新材料需求量、旧材料需求量、销售量均降低;追求高回收率的政策并不总是有效的;而提高WEEE的旧材料转化率对于闭环供应链有利.
為研究我國廢舊電子產品(WEEE)立法的問題,分析瞭供應商、製造商、零售商、需求市場及迴收商的行為,分彆建立瞭變分不等式模型,併在此基礎上建立瞭五級再製造閉環供應鏈網絡均衡模型.模型攷慮瞭政府對于製造商的懲罰政策與對于迴收商的補貼政策.通過脩正投影算法求解算例,倣真分析瞭舊材料轉化率、迴收率、懲罰及補貼政策對閉環供應鏈網絡均衡結果的影響.結果錶明,隨著政府對于迴收商的補貼的增加,不但迴收商的迴收量提高,閉環供應鏈的新材料需求量、舊材料需求量、銷售量均增加;相反,隨著政府對于製造商未完成的迴收量的罰款增加,迴收量、新材料需求量、舊材料需求量、銷售量均降低;追求高迴收率的政策併不總是有效的;而提高WEEE的舊材料轉化率對于閉環供應鏈有利.

To examine issues regarding waste electronic and electrical equipment (WEEE) legislation in China,the behavior of the supplier,the manufacturer,the retailer,the demand market and the collector are analyzed and the variational inequality models are established,and a five-tier remanufacturing closed-loop supply chain network equilibrium model is developed. The model considers the penalty policy to manufacturers and the allowance policy to collectors by the government. A modified projection method for variational inequality is used to solve numerical examples. It demonstrates the influence of the changing of parameters for the closed-loop supply chain equilibrium result. The result shows that the equilibrium quantity results increase with the increase of the allowance given by the government whereas they decrease with the increase of the penalty to manufacturers. It indicates that it is not efficient for the policy of pursuing a high collection rate. However,the increase of the WEEE old material 's recovery rate may benefit the closed-loop supply chain.
