By comparing the standard material flowing diagram and actual material flowing diagram, the main reason obtained of high energy consumption per ton steel is the unreasonable material flow.

The books logistics of universities and colleges exist such problems as that the idea of modern books logistics has not been set up,the information flow is not smooth and the standardization degree is low.

Based on the fundamental theory of logistics and that of outsourcing and fuzzy mathematics, the dissertation is about a tentative research on the optimal selection of books logistics outsourcing and service provider in China at present.

A concept of standard material flow diagram of steel manufacturing process is proposed.

Many measures to reduce the energy consumption and the proposal of standard material flow diagram at Xuanhua Steel are presented,based on the idea and theory of systematic energy saving and analysis of the practical energy consumption and flows.

Based on the concept of standard materials flow diagram (SMFD) of steel manufacturing process, the concept of SMFD of alumina manufacturing process was put forward and the SMFD of Bayer sinter combination method was constructed.
