廢棄電子產品逆物流網路模式設計

本研究以電子廢棄物（electronic waste, e-waste）回收後並再生處理作為考量，設計一成本最小化之電子廢棄物逆物流網路模式，以求解電子廢棄物逆物流網路中，拆解處理中心、回收中心、維修中心、及再製工廠之設施區位選擇，與再生產品之最適數量規劃，以達成廢棄物減量及保護自然資源之目標。此模式為一混合整數規劃模式（Mixed Integer Programming, MIP）。其逆物流網路階層分為收集中心（collection center）、拆解處理中心（disassembly center）、回收中心（recycling center）、維修中心（repairing center）、焚化廠（含垃圾掩埋場）（disposal sites）、再製工廠（assembly factory）、主要市場（primary market）及二手市場（secondary market）等。此模式，針對不同產業之處理流程，調整相關階層及參數，並轉換成合適的逆物流供應鏈網路架構，達成資源回收與再利用之妥善規劃。

This research develops a mixed integer programming (MIP) to solve the optimal design of reverse logistics for e-waste. The objective of the model is to minimize the total operation cost considering variety of resource recovery, multi-echelon, and demand. The reverse logistics network comprised of collection centers, disassembly centers, recycling centers, repairing centers, disposal sites, assembly factories, primary markets and secondary markets. The total cost includes facility cost, recovery cost, processing cost, remanufacturing cost, and transportation cost. Numerical experiments are conducted to illustrate the model capability for reverse logistics. The proposed model could also assist in determining the facility location, route and flow of different varieties of recyclable products in the multi-product, multi-echelon and multi-facility decision making framework through proper parameter settings.
