Design of Optimization Model for Cable Network Among the District in Urban Community;

Taking technology system of municipal solid waste (MSW) treatment and disposal in China as a case, Mento-Carlo numerical simulation and sensitivity analysis are studied in several typical scenarios by using the material flow and economy optimization model constructed previously.

Based on the characteristics of economic development and serious water pollution of the middle and lower Hanjiang River, an optimization model for discharge outlet distribution on the river section is developed so as to make full use of the water environment capacity and save investment.

In this paper,we try to construct an optimal model to establish the internal relationship among ra.

It is pointed out that sum-product priority vectors are the solutions of optimal model under certain deviation criteria.

The integration pattern of regional tourism information system was introdwed and an optimum model for tourism information transmission was built in order to achieve the best possible result in terms of high speed,maximum reach,and lowest cost.

The analysis of temporary increase and permanent increase in money supply using IS-LM model——in comparison with DD-AA model;

With the traditional IS-LM model and the comparative static analysis,this paper investigates fiscal policies capability in smoothing economic fluctuation since China s reform and opening-up.

This paper sets up simultaneous equation based on the IS-LM model,using historical data between 1980 and 2000,and makes the regression analysis by the method of two stage least squares.
