Resource price is measured with fuzzy mathematic method at first, and then environment price is calculated with the method of average increase cost.

To analyze the impact of demand information delay on order variation and average costs in a supply chain,a two stage supply chain with ARMA(1,1) demand,which consists of one retailer and one manufacturer,is considered.

For example,the average change rate is written as average cost.

Study on Incremental Cost and Economy of Water Saving and Reuse System in Green Building District;

As to the common problem reflected by society that the cost of building energy-saving is too much expensive,this paper discussed the influence of building shape coefficient on incremental cost of building energy-saving through typical design cases for low building,multilayer building and high-rise building,and proposed some suggestions and measures for the building sharp coefficient control.

The incremental cost as a result of energy-saving or ecological technology for green buildings will lead to the fluctuation and change of the cost of real estate market.

According to the theory of agile manufacturing,the paper discusses two methods of solving historical cost:one is establishing virtual enterprise to decrease the accumulation of historical cost,and the other uses historical cost instead of increment cost by adopting the flexible manufacturing technology.
