DIRECT PRODUCT PROFITABILITY AND RETAIL SHELF‐SPACE ALLOCATION MODELS
首次将直接产品盈利性（DPP）方法整合到货架空间优化模型中，帮助零售商在给定产品组合下更合理地分配货架空间，而非仅依据销售额或毛利率。
Given an assortment of k products, a retailer must make an important decision on the percentage of space allocated to each of them. Optimization models for this problem have previously shown that an item's space should not simply be given in proportion to its sales or its gross margin (GM). Calculations of Direct Product Profitability (DPP) have improved upon the GM concept, but the present paper is the first (of which we are aware) to integrate the DPP approach into a shelf‐space optimization model.
