        讲座题目：When to Offer Upgrades?

        内容简介：In this paper, we build a capacity and revenue management model from a consulting project. We consider a firm that sells multiple product models corresponding to multipleclasses of demand (customers). Each class of customers requests for one particular productmodel, and the firm can offer customers free upgrades to more expensive models when there isinsufficient stock of the preferred ones. However, customers may not accept the upgrades due totheir preferences on their desired models. Customers arrive over time. The firm needs to decidewhether or not to offer upgrades upon the arrival of each individual customer. We formulate theproblem using a Markov decision process model and prove that the optimal profit function isanti-multimodular. Based on this property, we prove that the structure of the optimal upgradepolicy can be described by dynamic thresholds that depend on the inventory levels of all products. Importantly, we show that, with the possibility that customers would reject upgrades, itis optimal to offer upgrades before the stockout of the desired models. Offering upgrades onlyafter stockout could lead to significant profit loss.
