Although modern logistics networks (LNs) plays a major role in effective cutting the cost of enterprise, studies that deal specifically with the dynamics of logistics networks are few, which is very common in circumstance of e-commerce. In order to provide a vehicle for dynamic modeling and analysis of logistics networks operations in vague and uncertain environments, we present our ongoing work on developing a multi-agent model for intra-organizational logistics management and using Lagrangian relaxation to decompose the problem into a set of subproblems.

Logistics system, being one of the most important sectors that offer substantial supports to national economy, its reliability and stability has a direct impact on the healthy development of national economy. With demand of modern integrated logistics service upgraded, the traditional chain-like structure of logistics system is being developed into a networked one. Taking the perspective of logistics service, the research conducts a deep analysis on the connotation of logistics network service and the basic structure of logistics network based on service relationship. Then the reliability of service provider/demander of logistics network is calculated. The research puts an emphasis on calculation of integrated logistics service reliability offered by logistics network with network-optimizing functions to fulfill optimal allocation of resources and concludes with some research suggestions.
