The model of project investment decision-making based on comprehensive weight and its use;

Aiming at these problems, this text put forward the investment decision-making model which is based on the comprehensive weight, this model considers the relation of all index comprehensively, and calculates the comprehensive weight of all index, then gets the comprehensive att.

Through the investigation on the structure and ecological benefits of shelter-belt on farmland in Ningxia and the analysis of comprehensive weight index, that the important roles played by large net, multi-shelter belt and mixed multi-tree-species in the construction of protection forests is explained.

Method integration and variable weight synthesis in solving hybrid objective systems;

In this paper, we firstly analyze the effect of variable weight synthesis.

Objective function of variable weight synthesis is introduced as the foundation on which the optimal design for the parameters of speed control system is made by genetic algorithm.

The integrating entropy assessment is combined with the weights given by experts to attain the comprehensive weights for evaluation.

Consider that it has to take cost to promote survivability,a synthetic tradeoff model of the survivability of networking air defense missile systems and combat cost .

Considering that it has to take cost to promote aircraft survivability, a synthetic tradeoff model of aircraft survivability and life circle cost is built.

Research on variable weight synthesizing model for condition evaluating on large steam turbine;

A synthetic method to assess the software requirement risk is proposed by applying the grey relational analysis and variable weight synthesizing theory.

Aiming at large-size steam turbine DEH governing system is complex and difficult to evaluate their conditions, a method of variable weight synthesizing condition evaluation of DEH system is firstly proposed on the basis of analysis on the condition effecting factors of DEH system.
