在价值工程活动中,功能分析是价值工程的核心。功能评价是功能分析的重要内容。功能评价的目的是确定价值工程活动的重点对象,为发挥创造能力、进行设计构思、提出改进设想、提高产品价值打下基础。功能评价的方法很多,大致可分为两类:一类是价值标准评价法,包括理论成本标准法、实际成本标准法等;一类是技巧评价法,包括 In value engineering activities, functional analysis is the core of value engineering. Functional evaluation is an important part of functional analysis. The purpose of functional evaluation is to identify the key objects of value engineering activities, and lay the foundation for the development of creative capabilities, design concepts, suggestions for improvement, and product value enhancement. There are many methods for functional evaluation, which can be roughly divided into two categories: one is the value standard evaluation method, including theoretical cost standard method, actual cost standard method, etc.; the other is skill evaluation method, including
