Through analysis on records in the information database in power plant, we can get performance data that are more close to reality. This paper use weighted average method to analysis records.
因此研究了采用机组实际运行数据分析获得的方法，采用加权平均方法从数据库大量记录中提取性能数据。
The fuzzy weighted average operations are common ones in the assessment and decision analysis when the value and weight are described to triangular fuzzy number.
定义了满足权重要求的模糊权重向量，利用三角模糊数的截集，给出了模糊加权平均数的计算原理、步骤和一种简便的近似方法。
At the same time, gas turbine blades, bearing materials and cutting tool materials were evaluated by Weighted Average, Improved Grey Relational Analysis (IGRA)and Fuzzy Assessment, respectively.
此外，运用加权平均法、改进灰色关联度法和模糊综合评价法分别对候选燃气涡轮叶片材料、轴承材料和刀具材料进行了评价。
