Research on Rational Distribution of Cement Industry——Model and Its Application Ma Yunchang;Lin Renzong;Chou JienqiangThe rational distribution of cement industry is of great importance to the development of cement industry and even of the national economies as a whole. In this paper, the methods of systems engineering are first applied to the cement industry distribution of ottr country, with a mathemat- ical model provided for this purpose according to the special conditions of our country. The model proposed consists of three sub-models which are constructed by the methods of discomposition and cooridination. A computer programme has been given to be applied in the pra- ctical computation of the model proposed by the authors. The resu- Its show that the model is rational and practical. A good econo- mical effect can be obtained by using the model to the cement in- dustry distribution of our country.
