Abstract

This paper considers the problem of real-time dispatching of a fleet of heterogeneous automated guidedvehicles (AGVs) with battery constraints. The AGV fleet is heterogeneous in terms of material handlingcapabilities; some can tow loads, some can lift loads while others manipulate loads with the assistance ofa robotic arm. Transport requests arrive in real-time and include a soft time window, with late deliveryincurring tardiness costs. Transport requests need to be assigned to a capable AGV based on requiredmaterial handling capabilities with the objective to minimize a weighted sum of tardiness costs of transportrequests and travel costs of AGVs. In this paper, an AGV-specific linear dispatching rule (LDR) learningapproach is proposed to assign AGVs to randomly arriving transport requests in real time over a finitehorizon. The proposed approach is compared with a heuristic policy from practice by using real-worlddata provided by our industry partner.
