本文基于Topsis法对柴油机整机性能进行综合评价。该方法是一种有效的多目标决策方法逼近于理想解的评价方法。采用Topsis的评估方法,能有效回避传统评估方法中将多评估参数综合成单一效能量度值的困难,为柴油机整机性能综合评价提供了一种新的途径。 This article based on the Topsis method of diesel engine performance evaluation. This method is an effective multi-objective decision making approach to the evaluation of ideal solutions. Using Topsis assessment method can effectively avoid the difficulty of integrating multiple assessment parameters into a single performance measurement value in the traditional assessment methods, providing a new approach for the comprehensive evaluation of the whole diesel engine performance.
