Study On The Fuel Management In Electricity Generation Enterprises Under The Condition Of Coal Supply Marketization

At present, with the open price of coal market, the sharp increase of coal price make the firepower generation factories in dilemma. In order to alleviate the contradictory between the coal and power, and reduce the electricity generation cost caused by the coal price increase, there are twice coal-electricity linkage in our country, which haven't solve the difficulty of electricity generation firms as well as dispute over the coal and electricity firms radically. Nowadays, the electricity price is operated under marketization yet, so the enhancement of fuel supply management and the reduction of inventory cost will be the important way to ensure the effective operation. This paper begins with the fundamental EOQ model of inventory management, combines with the frequent fluctuation of coal demand and price change, then introduces the modern production management model and concept such as MRPⅡand JIT into the study of fuel inventory management, at last brings out the improved EOQ model based on price changes. Meanwhile, in order to improve the harmonious development of the coal and electricity power industries, the paper have a deep research into the perfection of the coal-electricity linkage system, which is in expectation of some good effects of this policy.
