  1. The main contributions of this dissertation are listed as the followings : l ) deducing and proving the " three in one " theory of natural monopoly, that is, from the angles of economies of scale, economies of scope and economies of network, giving an explanation of natural monopoly ; 2 ) putting forward the concept of " strict superadditivity " and proving that total value function and total revenue function of network economy have strict superadditivity ; 3 ) summarizing the emerging characteristics in the market definition of natural monopoly, that is, in the monopoly industry, " market " tends to be more and more smaller than " industry " ; 4 ) expounding that the objective patterns of regulatory reforms of the railway industry in china are explicit regulation with partly characteristics of implicit regulation ; 5 ) proving the idea that the structural reforms of the railway industry in china should be hierarchical ; 6 ) demonstrating the theoretical bases for whether infrastructure management should be separated from transpo rt operation ; 7 ) expounding and proving that the interior of the railway industry in china should implement the differential property rights reform pattern

    本文的研究特點在於： （ 1 ）在規模經濟、范圍經濟的基礎上進一步推導並證明了網路經濟與自然壟斷的關系，即自然壟斷可以從規模經濟、范圍經濟、網路經濟三個角度來解釋論述； （ 2 ）明確提出了一個與鮑莫爾、潘澤與威利格等人提出的「成本劣加性」相類似的概念? ?價值優加性，並證明了網路經濟的總價值函數和總收益函數具有嚴格優加性； （ 3 ）概括了自然壟斷市場界定中所出現的新特徵，即在壟斷產業中， 「市場」正越來越小於「產業」 ； （ 4 ）進一步論證了中國鐵路產業規制創新的目標模式是兼有部分內生規制特點的外生規制； （ 5 ）在中國鐵路產業的結構改革中應體現分層次的思想； （ 6 ）明確論述了內容提要鐵路路網公司等自然壟斷環節是否分割的理論基礎; （ 7 ）提出並進一步證明了中國鐵路產業內部應實行差異化的產權改革模式。
  2. The author first summarizes the researches on rbd, both at home and abroad, such as its definition, function, formation, driving force, product series as well as its relationship with cbd. then the author provides several strategies for developing city rbd, including making better use of government macro regulation, retaining unique features, enhancing image formation and publicity and strengthening administration of rbd. the fourth part employs the relevant theories of rbd discussed above to analyze the subjective and objective requirements of rbd development in jinan

    文章的第四部分以濟南市商業遊憩區的發展為實證，運用前面所論述的城市商業遊憩區形成發展的相關理論，分析了濟南市商業遊憩區發展的主、客觀需求，界定了濟南市商業遊憩區的范圍，闡述了濟南市商業遊憩區發展的供給條件、需求條件、支持條件等動力條件，最後文章分析了濟南市商業遊憩區的發展趨勢，認為濟南市商業遊憩區將論城市商旅聯動及其商業遊憩區的發展成為遊客在濟南的首選中心旅遊區，而且將形成良性發展循環。
  3. A ptas is designed for the problem when the batch capacity and the number of machines are both constant. 1. definition and assumption definition l + o ( ) cost : each transformation potentially increases the objective function value by 1 + o ( ), we shall say it produces 1 + o ( ) cost

    在以下兩方面發展了brucker ， foto等人的成果，一是工件具有了到達時間和分批加工的復雜狀況，二是機器環境有單臺機器變為同型機，並給出了它的一個ptas演算法。
  4. In spite of different methods to a fuzzy optimal solution to the two classes of fuzzy linear programming, these methods have similar ideas : first is to fuzzify the objective function and constraints, i. e., to display the definition of fuzzy membership function. second is to transfer the fuzzy linear programming into one general linear programming, based on the fuzzy decision, then we can obtain the fuzzy optimal solution by solving this linear programming

    雖然求這兩類模糊線性規劃的模糊最優解的方法並不相同，但其思想具有相似性：首先是把目標函數或約束條件模糊化，給出他們的隸屬函數的定義；然後給出模糊判決，在此基礎上，規劃最終都可化為求一個普通規劃的解，這個解可看成模糊線性規劃的模糊最優解。
  5. To solve the problems of adaptive determinition of the cluster number, flexible objective function definition and approximate optimal computation in clustering analysis, a ga - based divisive hierarchical clustering algorithm ( gadhc ) was proposed, which integrated some features of divisive hierarchical clustering algorithm and binary genetic clustering algorithm

    摘要針對聚類中自適應確定聚類個數、目標函數靈活定義及優化的近似計算等問題，綜合了分裂式層次化聚類演算法能根據相似度閾值自適應地確定聚類個數的特點及二進制遺傳聚類演算法具有較強的搜索近似最優解能力及目標函數定義靈活的特點，提出了一種基於遺傳演算法的分裂式層次化聚類方法。
