报告摘要：This paper considers the operational management problems under a newly introduced choice model that captures the effect of focality. The offered assortment is separated into the focal set and the non-focal set in this model due to the bias of focality, which is identified by the focal sets and an assortment dependent focal parameter. This focal multinomial logit model generalizes the famous multinomial logit model and some well-studied consideration-set choice models. In this work, we focus on the threshold focal set and various focal parameter settings, including the constant, cardinality and linear focal multinomial logit models, as well as a broader model that satisfies certain regularity conditions and subsumes the above models. We characterize the computational complexity and propose polynomial-time exact or approximation algorithms to solve the assortment optimization problem under different focal parameters. We then study the optimal strategy for the joint price and assortment optimization problem.
