A dynamics model for evaluating operation benefit of water conservancy economic system, which corresponds to energy index in the engineering power system, is established according to the optimal control theory The reasonableness and feasibility of the model are witnessed by computational results of Jiangsu water conservancy economic system
The economy also has effect on water environment, which involve water demand and contamination. This paper adopts wavelet neural network model to predict and analyze the area water demand and contamination elimination, to evaluate the effect of environment on economy.
In this paper the possibility of mutual interaction between modern controltheory and economic system research is explored.First,the course of economictransformation and the rapid development of national economy bring about manyproblems which need to be tackeled with the help of modern control theory.Onthe other hand,modern control theory can provide economists with useful tools.The author also suggests some possible links between the two fields.(
This paper discusses rural population-land-economy system and its operation model and onthis basis analysizes the actuality and characteristics of this system in Jiangsu Province.The author also putsforward some countermeasures and suggestions from strategy transformation,population migration,re-source exploition and zoning co-operation and provides some information in the lysising of the entropy in-crease of Chinese population-land-economy system.
The supply capability in coal development is a comprehensive index of coal capital construction and prodtlction, the capacity of supply and marketing and transportation. The solution of the contradiction between supply and demand depends mainly on the economical system. Therefore,when studying the coal supply capability,we should consider it as a system. Based on the principle and methods of system dynamics(SD),this paper considers the major factors affecting the supply capability in coal development to be ...
