应用层次分析法(AHP)对煤炭供应商从经济性、煤质要求、价格、商业信誉等几个方面进行综合评判,并用软件实现评判结果,给煤炭采购单位选择供应商提供参考,最后用一个算例说明方法的有效性。由于我国的能源结构决定了我国的电力工业是以燃煤火电为主。发电企业是煤炭需求的最大用户。目前发电用煤占我国煤炭产量的50%以上,这一比例在将来相当一段时间内会继续保持。虽然目前煤炭价格持续下降,但是燃料成本在发电企业的总成本中依然不低于65%。从节约成本,增加利润的经济性来看,选择合适的煤炭供应商或最优的煤炭供应方式十分必要。
Analytic hierarchy process (AHP) is used to evaluate the coal supplier from several aspects such as economy, coal quality, price, business reputation and so on, and to judge the result by software, to provide a reference for the coal supplier to choose the supplier. Finally, An example illustrates the effectiveness of the method. As China’s energy structure determines the power industry in our country based on coal-fired power. Power generation companies are the largest users of coal demand. At present, coal for power generation accounts for over 50% of China’s coal output, a proportion that will continue to be maintained for a considerable period of time in the future. Although coal prices have been declining, the cost of fuel remains at a minimum of 65% of the total cost of power plants. From the cost-saving, profit-making economic point of view, the choice of the right coal supplier or the optimal supply of coal is necessary.
