摘要以一種有向帶權類依賴圖作為面向對象系統的uml類圖的抽象表示，結合信息熵技術針對軟體構件進行內聚耦合性及獨立性度量。Expanding capital operation, as an important part in development strategy, is closely related with the long - term development of listed companies, therefore, listed companies should hold strategical view in planning and making - decision in conducting expanding capital operation. based on sustainable development principle, the dissertation analyses the essence of expanding capital operation and its basic models according to the theories of capital operation ; combined with existing situation of china ' s listed companies, analyses internal causes and external factors which lead expanding capital operation falling into dire straits, and advances that using strategy is a breakthrough point to solve the problem. then, with the logical line of strategical management " analysis of strategical environment - settlement of strategical targets - drawing - up and choosing strategical model - implementing and controlling strategy - assessing strategy ", brings strategy into expanding capital operation process, analyses factors effecting expanding capital operation, and constructs decision - making model for choosing strategical styles ; in the implementation stage, focus on fixing exchange price and the whole integration management ; at final, using conglomerate m & a strategy as an example, utilizing entropic measure method, regression - analysis, variance - analysis and spss digital - statistic software, constructs a model to illustrate the relationship between diversified m & a strategy and economic performance of listed companies, puts forward the suitable expanding capital operation style for china ' s listed companies, and gives some suggestions
本文以公司持續發展為原則，根據資本運營理論，分析外擴型資本運營的內涵及其三種基本模式；並與我國上市公司的實際情況相結合，分析目前上市公司外擴型資本運營陷入困境的內在原因和宏觀因素，提出以戰略為支撐是我國上市公司外擴型資本運營走出困境的突破點；然後以"戰略環境分析-戰略目標定位-戰略制定及模式選擇-戰略實施與控制-戰略評價"的戰略管理邏輯主線，將戰略引入上市公司外擴型資本運營的各個階段，分析了影響上市公司進行外擴型資本運營的內外部因素、確立戰略性經營目標，構建我國上市公司外擴型資本運營戰略模式的決策模型；在戰略實施階段，重點研究交易價格的確定和全面整合管理；最後，以目前我國上市公司外擴型資本運營中常見的混合併購模式為例，運用熵測量法、回歸分析、方差分析等計量方法及spss大型數據統計軟體，構建模型，研究上市公司混合併購戰略與經濟績效的關系，在分析結果的基礎提出適合我國上市公司發展的外擴型資本運營模式及相關的建議。By analyzing expression between a and fuzzy entropy from the view of analytics, this paper analyses the relationship of between a and fuzzy entropy and the changing trend of fuzzy entropy function with the increase of a, then discusses the sensitivity of the parameter a to classification result such as total nodes, rule number, classification accuracy of fuzzy decision tree, proposes an experimental method of obtaining optimal a, it is proved by experiment that the optimal value a obtained by this method can make the classification result of fuzzy decision tree best, and therefore provides the academic evidence of selecting parameter a in order to gain the best classification result
本文在visualc + +軟體開發平臺及模糊id3演算法的基礎上，從解析的角度出發，通過分析參數與模糊熵之間的函數關系式，討論了隨著的增加，模糊熵函數的變化趨勢，進一步分析了參數對模糊決策樹的分類結果在訓練準確率、測試準確率、規則數等方面所表現出的敏感性，探討了得到最優參數的實驗方法。實驗證明，利用這一方法得到的最優參數的值，可以使模糊決策樹的分類結果達到最好的效果，從而為人們用模糊決策樹進行分類時選取參數以獲得最優的分類結果，提供了良好的理論依據。
