The withdrawal of criminal cases will result in criminal proceedings end,it is likely to fall victim choose to pursue the request,and at last led to the victim "secondary victimization".

In this system, a new hybrid layered voltage control models is set up, the discrete events are taken as the drives of the system, and the synthetic objects are achieved.

Arising from the randomly discrete events and the modeling methods in the discrete systematic simulation, the modeling is created on the basis of the analysis of technological process of loading and unloading in harbors as well as the operational management system.

To solve the optimization problems of discrete events under dynamic environment in the real world,particle swarm optimization(PSO) algorithm is studied,which is used widely to solve the optimization problems in the dynamic environment or discrete operation at present,and a dynamic discrete PSO algorithm is proposed.
