报告内容摘要


报告内容:

Choice-Based Facility Location (CBFL) arises in various industrial and business contexts, focusing on strategically locating service facilities to improve market competitiveness or achieve strategic objectives. The problem stands on a decentralized perspective, where individual customers make their own decisions regarding which company or facility to visit, based on their specific preferences. In this regard, the company is unable to dictate customer allocation to facilities in a centralized manner but instead must rely on designing effective service profiles to attract and retain customers. In this seminar, we will start by exploring the practical applications of CBFL, including the placement of parcel locker stations for last-mile delivery, the design of omnichannel fulfillment networks, and the strategic planning of urban park-and-ride transportation systems. Overall, CBFL can be classified into two streams, i.e., CBFL under static competition and CBFL under leader-follower competition. Static competition focuses on a single company with the assumption that competing companies will not change their services during the planning horizon. This stream has been studied extensively, giving rise to a large number of decision models. To facilitate the decision-making of partitioners, this talk provides a unified model, which can represent most of the CBFL problems and can be solved efficiently by decomposition algorithms. On the contrary, leader-follower competition studies multiple companies, and each company is assumed to maximize its own objective. There exist interactive decisions at the company level. The related problems are typically formulated using bilevel programming. In this talk, we discuss a general bilevel model for CBFL under leader-follower competition. Efficient algorithms are proposed and tested on various datasets to draw managerial implications.
