- W2358966891 abstract "In order to increase the market competence of a coal operation and its capabilities in coal quality promotion and optimize profit from coal production,an optimization model on commercial coal ranks based on the theory of systems engineering was proposed under the constraints of market demand in Jizhong Energy Xingtai Mining Area,with system engineering theory and method,analysis of production rate,quality of coal,break-even point etc.to get the maximum profit,combined with the actual mining,commercial coal types were optimized,the result showed that the annual profit of the mining area could be raised by more than 27%." @default.
