META-SYNTHESIS APPROACH TO EXPLORING CONSTRUCTING COMPREHENSIVE TRANSPORTATION SYSTEM IN CHINA

1 Introduction Transportation is a basic and indispensable element in social economic development Great achievements have been reached intransportation in China since the adoption of reform and opening policy in 1978 To meet the continuously increasing demands from the socioeconomic development for a harmony andwell-off living society, a national integrative transportation system instead of separate planning by individual transport mode has been under consideration to deal with old and emergin…

A message-driving formalism for modeling and simulation of multi-agent supply chain systems

To acquire a competitive advantage in the expanding market, manufacturing enterprises should be able to manage their supply chains as effectively as possible. It is now becoming popular to model supply chains as multi-agent systems and use discrete event simulation to learn more about their behaviors or investigate the implications of alternative configurations. In order to enhance the computational efficiency and keep the simulation credibility, this paper proposes a message-driving formalism for the simulation of multi-agent supply chain systems. Through the message-driving formalism, the problem of shared variables is addressed and the parallel operation of agents is implemented. Simulation experiments with a prototype implementation show that the message-driving formalism is able to provide credible results in significantly less simulation time.
