Grounded on the theory of circulation economy, this article uses Monte Carlo method to simulate the profits of six industry chains in YM Group and the whole system they combine, in the background of coal enterprise economic system. These six industry chains include coal, power generation, alumina, coal chemical, gangue brick, and cement.
