Research And Implementation Of Distributed Intelligence Quality Management For Coal Industry

As the rapid development of world economy, informatization, globalization, multipolarity as megatrend become more and more obvious. what's More, Informatization is called the engine to speed up modern world economy and the equalizer to coordinate social development. Informatization together with economy globalization, pushes global industry to divide deeply and economic structure to adjust, changes the world market and world economy competitive Structure, which makes global informatization become inevitable trend in the world economy development. The coal is a vital basic industry of Chinese economy, and also an important mark for China's national economy and society level and synthesis strength.In the year of 2006,the output of coal mine in China is about 2.325 billion ton, compared with the same period of last year increase by 8.09% and the consumption of coal is 2.3 billion ton, increase by 9.26% compared with the same period of last year,large-scale coal enterprises achieve profits of 67.7 billion Yuan, increase by 25.3% compared with the same period of last year. However, the informatization construction of coal industry in China is still in a low lever, Added with low investment. In summary, so long as we speed up the step of coal informatization in China, it will become more and more competitive in the world.This thesis takes Fujian coal-power limited liability company as the develop background for coal industry, Firstly, it introduces the design of the distributed application system of coal industry, secondly, it explains how to design and implement the quality manage system, which is a subsystem of the distributed application system of coal industry. The quality manage system can not only acquire measure data in measure department automatically, but decide which grade of quality the product is according to documents of enterprise. Meanwhile, with its user-defined structure, The system also have strong report function. It is not only cut down the labor of statistician but prevent errors by handwork. what's more, it makes unified planning transformed into reality. Finally, this thesis draws into technology of coal blending which have close relation with quality manage of coal industry. To expend the traditional linear weighted model for coal blending, the thesis first prove in theory the index marks of finished product of coal blending have linear correlation with single coals which take part in coal blending,and furthermore, it builds a new model for coal blending which takes fare as influent factor into objective function and set weight coefficient for every single coal. As result, we can save excellent quality coal and make best use of faulty coal by means of adjust the parameter of weight coefficient. which makes coal blending become more practical.
