This paper presents a survey of vehicle routing problems with multiple synchronization constraints. These problems exhibit, in addition to the usual task covering constraints, further synchronization requirements between the vehicles, concerning spatial, temporal, and load aspects. They constitute an emerging field in vehicle routing research and are becoming a “hot” topic. The contribution of the paper is threefold: (i) It presents a classification of different types of synchronization. (ii…

A generic heuristic is described that allows to solve many important types of VRPMSs, concerning spatial, temporal, and load aspects.

A Greedy Heuristic for the Vehicle Routing Problem with Time Windows, Synchronization Constraints and Heterogeneous Fleet

Although the complexity of the AHTS-routing problem is higher than the VRPTWSyn, the proposed method could produce a diverse set of feasible solutions, which in the future may be improved by a meta-heuristic-based algorithm.
