Based on the "shortest path matrix", with the indexes "weighted mean travel costs" and "economic potential",the author studied the optimization of highway network in Hunan province and the evolution of spatial pattern from 1984 to 2004.

This hydrate has the highest economic potential.

The comprehensive reusable potential prediction models include the following: the prediction model of economic potential,based on the economics profit and loss balance principle,can determine the closing economic limitations of.

In the passage the author establishes an economical model to explain the graduate unemployment phenomenon and illuminates three kinds of consciousness that are needed in the exertion of the model.

An economical model is established for traditional machining center, high speed machine tools as well as virtual axes machine tools.

Based on the latest data of X oil field,an interactive computer-based economics model is established using the principle and methods of the system dynamics.

According to the principle and methods of the system dynamics,it draws the SD flow diagrams,then establishes an interactive computer based economics model with DYNAMO computer language.

Then an interactive computer based economics model is established with DYNAMO computer language.
