The Study of Vehicle Routing Model in Emergency Situations

Abstract:

A Vehicle routing model for logistics planning is developed in this paper. The model addresses the dynamic time-dependent transportation problem that needs to be solved repetitively at given time intervals during ongoing aid delivery. The model generates plans incorporating new requests for aid materials, new supplies and transportation means that become available during the current planning time horizon. The plan indicates the optimal mixed pick up and delivery schedules for vehicles within the considered planning time horizon as well as the optimal quantities and types of loads picked up and delivered on these routes. The mathematical model is a hybrid that integrates the multi-commodity network flow problem and the vehicle routing problem. Based on the analysis and calculation of an example, the results indicate that the model is effective and feasible.
