Dynamic Service Network Design Model of Same-day Parcel Express in Network-Alliance Mode

The dynamic service network design problem (D-SNDP) for same-day parcel express is studied based on highway passenger express network within the network-alliance mode. D-SNDP issues focus on the principle of generalized resources especially high-quality resource sharing or complementarity. Discrete time-space networks are applied to reconstruct a dynamic service network by putting into time dimension. Then, a conceptual model and an integer programming design model of dynamic service network are both proposed with multi-arcs given with multi-commodity of same-day parcel express. This model is minimizing the total operation costs of networking with constrains on service elements, including space, cost, capacity etc. The revenue-sharing model for alliance using the generalized resource contribution coefficient V is also proposed at same time. A case analysis shows that the design model and revenue sharing model indeed play a role in improving the efficiency of network resource allocation and promoting cooperation among alliance members.
