In some projects charged by our lab such as national 863 project - " crop planting management components based on weather analyse ", anhui provincial 95 key project - " agricultural meteorology disaster evaluation system base on gis in anhui province " and the project " small coal mine security management and decision system based on gis in anhui province ", this paper combines the theory and arithmetic of rough set with gis and data mining in idss, investiges the application of rough set theory to precision analysis of attribute data and logical operation in gis, analyzes the logical operation based on rough set ( logical union, logical intersection, logical complement, mixed logical operation etc. ), so that it can give a method y to research the gis attribute data and the uncertainty of attribute data after superposition operator, so as to express the roughness and illegibility of attribute data more accurately
在完成試驗室所承擔的國家863項目「基於氣象分析的農作物種植管理軟構件」 、省95攻關項目「基於gis的安徽省重大農業氣象災害測評系統」和「基於gis的安徽省小煤礦安全管理決策系統」等項目中，將粗糙集理論和演算法與gis 、智能決策系統中的知識發現等相結合，對粗糙集理論在gis屬性數據和邏輯運算精度分析中的應用情況進行了研究，分析了基於粗集的gis邏輯運算（邏輯並、邏輯交、邏輯補、混合邏輯等） ，從而為研究gis屬性數據及其疊加運算后屬性數據的不確定性提供了一種方法，能比較準確地表達屬性數據的模糊性和粗糙性。 -
Now information is obtained easier and easier. but when much information pushes to people, which makes people faced with data tragedy, how to get useful information from many data is a prodigious task. rs is brought out by the way of a new method to reduce the data. this paper researches rs and reduction arithmetic based on rs, establishes data mining model based on rs. rough neural network is put forward which combines rs and neural network. this net model is applied in the research of forecasting system about quantity of heat. the net model is validated through the data of coal analysis
本文在深入研究了粗糙集理論及其基於粗糙集理論的約簡演算法，建立了基於粗糙集理論的數據挖掘模型，在此基礎上，將粗糙集與神經網路相結合，提出了一種粗糙集神經網路，並將其作為基於神經網路的燃煤發熱量預測系統的網路模型，解決了基於神經網路的燃煤發熱量預測系統的技術問題，並結合具體電廠的煤質分析數據驗證了粗糙集神經網路模型的有效性。 -
