摘要
设计的多解性和相对性要求通过评价来确定最佳设计方案。技术经济评价法是德国工程师协会技术准则VDI2 2 2 5中推荐的方法。模糊评价法是近年来我国现代设计领域常用的一种方法。前者便于找出设计方案的弱点加以改进 ;后者适用于将定性的模糊信息定量化。对同一设计问题 ,两者的评价结论是否一致 ?比较了它们的原理、特点与应用范围 。
It is demanded to determine the optimal designing scheme by means of evaluation due to multi-solution character and relativity of the design.The technology-economical evaluation method was a method recmmended in technology criterion VDI 2225 by German Association of Engineers.Fuzzy evaluation method is a kind of method being used frequently in recent years on the domain of modern design in our country.The former method is convenient for finding out weak points of designing scheme and making additional improvement.The later is applicable to quantify the qualitative fuzzy information.But whether the evaluation conclusions of both method are coincident with a same problem of design or not?After the principle,characteristics and scope of application of these two methods are being compared,it is found out that their main difference lies in the weighted coefficient in dertermining the concerned economical evaluation factor.
