This paper deals with the routing planning of the delivery vehicle navigation in logistics,and proposes an improved particle swarm optimization algorithm suitable for the point-to-point model of vehicle routing planning.

This paper adopts a high-level Petri nets-based approach to build the multi-agent model of a supply chain, especially discusses the main ideas of approach and the steps for building the aggregation model by using sub-agent substitution, and gives an example.

Study of Enterprises Model Integration Based on XML and Web Service;

Based on general research of information model integration, incorporating with the service management requirement of operation-oriented network management, the paper proposes a management information model based on three-level abstraction.

Application of AMESim in integrated model of suspension and steering;

Project management integrated model for product lifecycle management;

In order to simulate and predict the eutrophic status of the Miyun Reservoir and its watershed,an integrated model was developed based on GIS and RS technology,which was composed of non-point source(NPS) simulation model,aquatic ecological-hydrodynamic model,and river water quality model.

Then with Lumped model, we simulated the concentration of xylose and xylitol in columns by material equilibrium and isotherms.
