Production characteristics and the optimization of development schemes of fractured gas reservoir with edge or bottom water;

Study on Scheme Optimization of Solid Waste Disposal in City;

In water pollution control planning,scheme optimization involves various evaluation indexes and different dimensions,and it is difficult to determine the weight of the evaluation indexes,so the digital information of indexes data can not be reflected objectively by using the common methods of water quality planning.

Three mathematical models of disposal scheme optimization are established.

In project optimization of water system management in mining subsidence,principals of problem optimal solution by Hopfield neural networks was applied.

With respect to group decision making problems with multi-granularity linguistic comparison matrices,a new approach based on two-tuple linguistic representation to group aggregation and alternative selection is proposed.

With regard to a kind of multiple attribute group decision making problems with linguistic assessment information, a new approach to group aggregation and alternative selection is proposed.
