CONTENT • Abstract • Introduction • Literature: Reverse logistics Product recalls and refurbishing Other relevant literature • The reverse distribution model • The solution approach • Computation results • Summary and conclusions
Literature: Reverse logistics 1/3 • 逆物流處理之四個主要基本原則: 1. Reduce 2. Substitution 3. Reuse 4. Recycle
Literature: Product recalls and refurbishing 3/3 • Refurbishing: 主要對於回送後的產品進行所需之改變,使其顧客滿意。 ( Lund, 1984 ) • 其議題包含:Recycling, Reduction, Reclamation, Recovery, Reuse, Remanfacturing. (Guintini and Ansel, 1995)
The reverse distribution model 2/5 • Product: This includes products that: have been recalled, recycled, disposed, or hazardous. • I––{i/i is an origination site}. • J––{j/j is a collection site}. • K––{k/k is a refurbishing facility site}. Includes a refurbishing site, a recycling plant, a decontamination plant, or the original manufacturing site.
The reverse distribution model 3/5 • Cijk––Total variable cost of transporting a single unit of recalled product from origination site i through collection site j and onto refurbishing site k. • Fj––Cost of opening a collection site j. 成本 • Gk––Cost of opening a refurbishing site k. • ai––Number of hazardous products residing at origination site i. • Bj––Maximum capacity of collection site j. 容量 • Dk––Maximum capacity of refurbishing facility k. • Pmin––Minimum number of collection sites to open and operate. • Pmax––Maximum number of collection sites to open and operate. 數量 • Qmin––Minimum number of refurbishing facilities to operate. • Qmax––Maximum number of refurbishing facilities to operate.
The reverse distribution model 4/5 The decision variables for the model are: • Xijk––fraction of units at origination site i that is transported through collection site j and onto refurbishing site k. • Pj 1 if collection site j is open; 0 otherwise: • Qk 1 if refurbishing facility k is open; 0 otherwise: 小部份直接 從I→K之產品 開放與不開放
