目前大型煤炭企业大多通过星型网络进行销售，其中运销公司作为网络中心，连接多个矿井与客户，维持煤炭企业和部分客户间的联盟关系。在煤炭交易中，矿井和客户通过随机抽样检测质量，确定交易价格。随机抽样影响了双方对煤炭质量的认同，并可能导致煤质纠纷。在研究中，通过对长期积累矿井和客户历史交易数据进行挖掘，提出应用贝叶斯概率方法，计算矿井和客户的信誉度及双方对煤质化验结果的适配度，使运销公司为矿井和客户推荐合适的交易方，减少了煤质纠纷，并确保了交易双方的利益。
目前大型煤炭企業大多通過星型網絡進行銷售，其中運銷公司作為網絡中心，連接多箇礦井與客戶，維持煤炭企業和部分客戶間的聯盟關繫。在煤炭交易中，礦井和客戶通過隨機抽樣檢測質量，確定交易價格。隨機抽樣影響瞭雙方對煤炭質量的認同，併可能導緻煤質糾紛。在研究中，通過對長期積纍礦井和客戶歷史交易數據進行挖掘，提齣應用貝葉斯概率方法，計算礦井和客戶的信譽度及雙方對煤質化驗結果的適配度，使運銷公司為礦井和客戶推薦閤適的交易方，減少瞭煤質糾紛，併確保瞭交易雙方的利益。

At present , the sale relation in large coal enterprise forms a star-like network , in which the sale and transportation company plays a center role , connecting multiple mines and customers and maintaining the alliance be-tween the coal enterprise and customers .In coal trading , mines and customers examine the coal quality through ran-dom sampling to determine the transaction price .But the random sampling affects their identification of the coal qual -ity, and may lead the disputation on coal quality .In this study, through mining the long-term accumulated transac-tion data between mines and customers , a Bayesian probabilistic method is proposed to calculate the credibility of the mines and the customers , the relative adaption degree on coal quality between the two dealers of transaction , and to recommend the suitable dealer for a possible transaction , thus significantly reducing the coal quality disputation and ensuring the profit for both parties .
