《价值工程》杂志1987年第6期发表了笔者文稿《VE述著中某些不妥观点的探讨》,现作如下补充。日本教授玉井正寿、秋山兼夫等人各自的有关价值工程著作中,均有二个不同概念的价值系数。它们的前部阐述价值工程的基本原理时,指出价值系数(V)等于功能(F)与成本(C)之比,即V=F/C,价值工程的目的是要尽可能提高价值系数,即V的值越大越理想;但是,在著作的后部叙述功能 “Value Engineering” magazine in 1987 the sixth issue of the author of “VE described in some of the wrong perspective,” is now supplemented as follows. Japanese professor Tamaki Ishii, Akiyama and husband and others in the respective works of value engineering, there are two different values ​​of the value of the coefficient. In their introductory section on the fundamentals of value engineering, it is pointed out that the value factor (V) equals the ratio of function (F) to cost (C), ie V = F / C. The purpose of value engineering is to maximize the value factor, That is, the larger the value of V, the more ideal; however, the function is described later in the book
