Abstract: Considering the importance of simulation method to the research of modern logistics system, an extensible simula- tion technology is proposed, which is driven by discrete events and utilizes modeling theory of virtual scenario. The technique of state information collecting & identification, task management mechanism basedon work scheduling, the rules for the establishment of 3D rendering evironment as well as the strategy of object-oriented 3D-modelling is elaborated. On this basis, several key technologies are particularly analyzed, including the drive mechanism of discrete events, the autonomous principles of objects behavior and equipment motion simulation under time advance, etc. Numeric algorithm synthesizing Gaussian integration, iterative method and Newton’s method is introduced to figure out the absolute coordinates of equipment. The logistics simulation platform constructed on the basis of visualization technology has the advantages of expandability, openness and universality. Additional instance is presented finally, to illuminate the effectiveness and feasibility of applying the platform mentioned above to logistics industry.
