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.

Variable Weights Synthesis and Additive Standard Multifactorial Functions;

With this variable weight vector,the result of variable weights synthesis is the weighted mean minus the half of weighted variance.

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.

This paper focuses on multifactorial decision-making with variable weights.

At the same time improved invariable weight aggregate,changed the weight value according to the factors configuration.

In order to avoid the appearance of the problem that the system collectivity function is affected by the serious flaw of single value, the synthetic method of variable weight is combined with the Expanded Weight of Arithmetic Average(EWAA)and the Language Hybrid Aggregate(LHA)arithmetic operators.
