在眾多行業之中,存貨管理與運輸業兩者是在供應鏈裡,碳排放量最多的。這些行業會產生大量的碳排放,讓物品保持良好的狀態,尤其是損耗性產品。最近,許多研究人員致力於減少碳排放,這與行業製定的碳政策有關。本研究考量到了單一供應商和購買者之間的供應鏈協調,結合了供應商管理庫存系統來管理,並且思量到了庫存與碳排放的決策。供應商使用兩種不同的情況將產品交付給買方的運輸方案,第一種情況是供應商通過一次設置-單次交付策略運輸產品,而第二種情況是一次設置-多次交付策略。碳排放成本也是根據碳稅政策計算的。這項研究的目的是在考慮最佳輸送量和每個生產週期有固定輸送次數的情況下,有效地將降低總成本並盡量減少總碳排放量。最後經由數值範例分析、敏感度分析,以了解各個參數對本模式之影響,並做出結論。
Inventory management and transportation are the main activities in supply chains that generate carbon emissions in many industries. The industries will produce carbon emission significantly to keep maintaining their item well, especially deteriorating items. Recently, there are many carbon emission issues causing enterprises and researchers to focus on reducing carbon emissions. This study considers supply chain coordination between single supplier and buyer, mixing with Vendor Managed Inventory system to manage inventory decision considering carbon emission and deteriorating items. The transportation scenario of supplier delivering the product to the buyer using two different cases, the first is when the supplier transports the products by single-setup-single-delivery policy, and the second is single-setup-multiple-delivery policy. Carbon emission cost is also calculated under carbon tax policy. The aim of this study is to minimize the total cost and reduce the total carbon emission considering the optimum delivery quantity and the number of deliveries per production cycle. Numerical example and the sensitivity analysis will be provided to show the solution of the proposed model.
