In this paper,a new forecast DSS was developed to meet the need of the economy development condition,in this DSS′s construction,a new concept basic model library was proposed based on which,the model libraries were generated to adapt the conditional variation of circumstances and to raise the reliable degree of predictio.

A basic model of reaction dynamics consisting of 60 chemical reactions among 19 active compounds,and a simplified model including only 27 reactions were developed for seeking reaction mechanism.

The key of the research in Collar's Pattern Auto-generation Expert System is to establish a collar's 3D basic model and to get the 2D structure and pattern of the collar on the basis of this.

The results show that in cases of inhomogeneous topologies with lane droping or high on-and off-ramp volumes the basic model has significant dev.

The present paper introduced a few basic models,indicated the applied range and limi ts,discussed the further research.

The basic models of optimal system is deduced in this paper which consists of production time, waiting time, total cost, profits, profit rate in system.
