Value concept in the value engineering reveals the relationship of positive and negative function and cost,and provides scientific standard for comprehensive analysis of behavioral value.Things have two sides—two-way evolution.In development,we should see what are lost while winning,and which one is important.In economic development,which are valuable,which are worthless,which are significant to most of people,which are meaningless for most of people? And what is the cost in ecology,society,and humanity.Why is it meaningless for wealth creation? It interferes with the further development of the future.We need to consider the development of value engineering.
