Constructing a model of shelf space allocation in product categories

In retailing, shelf utilizing is one of main methods in goods display. About shelf space allocation problem, allocating product categories to shelf space should be discussed first. In the past, most researches only have considered how to allocate product items within the same product category to shelves but seldom studied about the product categories allocation problem. If product categories allocation is unfitted in retail stores, retailers will spend a lot of costs of product categories reallocation. In this paper, a Distance-Weighted Adjacency-Based is proposed to resolve the product categories allocation problem.
