APPLICATION OF THE FITRADEOFF METHOD IN A PORTFOLIO PROBLEM IN THE CONTEXT OF REVERSE LOGISTICS FOR WHOLESALE

ABSTRACT The study investigates options to support the reverse logistics for wholesalers in a company. This big company, which do not have the name presented in this paper aims to improve the process of returning unsold items. At the moment, the process contained several rework-related losses. Hence, in this study two methodologies have been applied. The VFT has been used to structure the problem considering the multiple objectives presented by the Decision-Maker, in special those that are considered by sporting multinational. Also, the FITradeoff method has been used to identify the alternatives that should compose the portfolio of options concerning the reverse logistics. The portfolio problematic has been applied since it has been desired to obtain the subset of option to support the problem, constrained by monetary resources. Using the VFT, ten alternatives which were evaluated in ten criteria have been defined, and support by the FITradeoff method. As result, the alternatives five alternatives have been selected to compose the portfolio.摘要：本研究针对某企业批发商端的逆向物流支持方案展开探索。本文未披露名称的该大型企业，旨在优化滞销商品的退货流程，但当前流程存在多项与返工相关的损耗。为此，本研究采用两种方法论开展研究：其一为价值聚焦思维（Value-Focused Thinking, VFT），结合决策者提出的多重目标（尤其是该体育跨国企业所考量的目标）对问题进行结构化梳理；其二为FITradeoff法，用于筛选可纳入逆向物流方案组合的备选方案。由于受资金资源约束，需获取可支撑该问题的方案子集，因此采用组合优化问题建模方式。借助价值聚焦思维，本研究界定了10项备选方案并设置10项评估准则，随后通过FITradeoff法完成评估。最终筛选出5项备选方案以组成最终方案组合。
