Abstract: To solve the joint decision problem of category optimization,pricing and inventory control in a vertically differentiated products,the joint decision model of subset selecting,pricing and inventory under deterministic demandcase and stochastic demand based on the theory of consumer's maxmum utility and newsvendor model were developed respectively.A heuristic algorithm was developed based on the structure of optimal product assortment to find the optimal solution.The effectiveness of the proposed method was verified with numerical analysis,and the influence of store traffic and variation coefficient of demand on retailer's decision were researched.The results showed that the optimal product assortment in the risky case was a subset of the optimal riskless assortment.With the uncertainity of demand,the scale of optimal product assortment and retailer's profits was  decreasing in coefficient of demand variation,while the optimal price and inventory were fluctuated with the increasing of coefficient of demand variation.
