Dynamic multi-stage failure-specific cooperative recourse strategy for logistics with simultaneous pickup and delivery

This study proposes a novel dynamic multi-stage failure-specific cooperative (DMS-FSC) recourse strategy for solving the route failure which occurs in the VRPSPD. In the case of simultaneous transportation, the proposed DMS-FSC strategy allows a pair of cooperative vehicles to revisit each other’s customers with unmet demands by dividing the whole transportation route into multiple stages. An extended genetic algorithm with a new multi-stage paired vectors representation scheme is offered to more effectively deal with the proposed DMS-FSC strategy. It explores a more ideal <i>a priori</i> transportation plan for the VRPSPD by incorporating an acceptance criterion based on simulated annealing.<br>
