摘要
在提出相似理论基本原理的基础上,着重介绍了权重值的计算方法,进而给出了系统相似度的概念和公式,并通过实例探讨了利用相似理论计算机电产品相似度精确值及预测新产品可靠性的方法,最后指出了在具体的计算过程中需要考虑的一些问题。
The calculation of the weight value is introduced based on the principle of similarity theory. The concept and equation of the system similarity are proposed. The methods to calculate the similarity of an electromechanical product and to predict the reliability of a new product using the sitsimilarity theory are discussed with an example. Some issues that should be considered in the calculation are presented.
