讲座题目：A General Multiple Depot Vehicle Scheduling Problem
讲座内容：We study a general multiple depot vehicle scheduling problem in this paper. Given a fleet of vehicles based at multiple depots and a set of trips to be served, we aim to find a set of routes such that the total transportation cost is minimized and all trips are fulfilled. We call this problem “general” because many practical features have been considered, including heterogeneous vehicles, service start time windows, split loads, and the toll-by-weight scheme. These features, on the one hand, greatly increase the applicability of this problem; on the other hand, however, make the problem very challenging to solve. Based on the concept of cover, we formulate a set partitioning model for this problem. To solve the model, we propose two exact algorithms, namely, a branch-and-price algorithm and a branch and Benders decomposition algorithm. Both algorithms are built upon a branch-and-bound framework. Particularly, we design a column generation procedure equipped with an efficient label setting method to solve subproblems involved in algorithms. Computational experiments have been conducted, and the results have substantiated the effectiveness and efficiency of our approaches.
