三次设计中望目特性信噪比的讨论与改进

A discussion and improvement of signal to noise ratio on definite purposed character in three stage design

以实例说明了三次设计的望目特性信噪比计算式在工程应用中的不足 ,提出了明确目标和模糊目标两种望目特性信噪比的修正计算式 ,通过实例表明了望目特性信噪比的修正计算式的实用性 。

Living examples are taken to explain the deficiency of computational formula, used in engineering application, for signal to noise ratio on definite purposed character in three stage design. The revised computational formulas for two kinds of signal to noise ratio on definite purposed character——definite objective and fuzzy objective were put forward. The practicality of revised computational formula for signal to noise ratio on definite purposed character was demonstrated by means of living examples in order to popularize and put in use in engineering practice.
