Abstract: The temporal constraints of the Synchronized Pickup and Delivery Problem (SPDP) impose a complex scheduling problem for the service times at the customer locations. This makes the efficient feasibility checking of routes intricate. We present two different route feasibility checks for the SPDP and compare their practical runtime on a huge number of randomly generated routes. Furthermore, we generalize the concept of forward time slack, which has proven a versatile tool for feasibility testing of VRP variants, to the SPDP.
