Abstract: This papaer has analyzed some problems on value engineering and presented a set of solutions. Firstly, in funcion scoring process, when one function compares with itself,the function score should be 0.5 point,not the commonly used 1 of zero point. Secondly, the formulate of the most adoptable area method has been simplified as K=F2-C2, K has been used as an indicator for deciding both which runction should be improved and how to improve.Finally, for calculating the multi-base coefficient, a new method named as integrative-base has been suggest-ed.

Key words: Value, Engineering, Functional analysis, Most adoptable area, Integrative base
