摘 要：Many firms face a problem to select an assortment of products and determine their prices to maximize the total profit subject to a capacity constraint. Customers' purchase behavior follows the Multinomial Logit choice model. Our analysis shows the capacity is always fully used and the nested structure is lost when price sensitivities are product-differentiated. We propose a nonrecursive polynomial-time algorithm for the joint assortment and multi-product price optimization.
