香港特區一直奉行寬松開放的入境政策，方便訪客來港經商、探親觀光或旅遊度假。香港特區歡迎真正的商人及企業家前來，投入資本及運用專業知識在港營商。外籍人士如具備香港所需而又缺乏的特別技能、知識或經驗，並獲與市值薪金大致相若的條件聘用，或能夠對本港經濟作出重大貢獻，可獲準來港工作和投資。The problem has been studied from two sides, firstly, from the viewpoint of applicability, based on the development strategic objectives of the oil company, with the aim to unify the exploration and extraction decisions of the resources in an integrated framework, and integrate the macro economic and technical objectives with micro economic and technical models of an oil well, an integrated non - linear dynamic optimal control model has been constructed, the objective is the benefit maximum of the exploration and extraction of the resources, and the optimal strategies are obtained by changing the problem into a non - linear mathematical programming problem, on the other hand, from the more macro level, based on the analysis of the characteristics of the exploration and extraction activities of oil and gas resources, a conclusion is easily deduced that the procedure is full of randomicity, then discovering procedure of oil deposit is proved to be a poisson process, and the reserves process is a supermartingale process, so the model of exploration discovery rate and the reserves model could be constructed
本文從兩個側面對此問題進行了研究，首先從實用性出發，以公司層次的戰略性規劃目標為基礎，將勘探階段與開發階段的工程技術及經濟方面的決策整合在一個模型框架內，同時將宏觀層次的經濟技術目標與單個油氣井生產的微觀技術經濟模型相結合，以油氣資源勘探與開發的經營效益最大化為目標，建立了一個非線性確定型綜合動態優化模型，通過將原非線性最優控制問題轉化為一非線性數學規劃問題進行了求解。其次從相對更宏觀的層次上，通過對油氣資源勘探與開發的特點分析，認為具有很強的隨機性，證明了勘探活動發現油氣藏的過程為一泊松過程，所發現的油氣藏儲量為一上鞅過程，在此基礎上，建立了油氣藏勘探發現率模型及儲量模型，在油氣價格服從幾何布朗運動條件下，以油氣開採收益最大化為目標，建立了一個油氣資源勘探與開發的隨機最優控制模型，採用動態規劃方法得到了值函數的hjb方程，並針對方程的特點，以及方程及其變量所對應的經濟學意義，對最優策略的求解進行了一些討論。It can be known that using pr ( product rule ) method combining with fs ( frame structure ) method can make knowledge expression more convenient and practical. using the " loose & tight coupling " style not only maked for the refresh, expand and administration of knowledges but also can improve the efficiency of system inference. aiming at different inference phases and problems, combining rbr ( rule _ based reasoning ) with fm ( fuzzy matrix ) reasoning by using different inference mechanism is easy to realize solve strategy of the fuzzy inference mechanism
通過該系統的具體開發可知，採用產生式規則和框架系統相結合的方式，可以使領域知識的表達更加方便、實用；應用松緊耦合的方式建立系統知識庫，不僅有利於知識的更新、擴展與管理，而且能提高系統推理的效率；針對制動器設計過程中不同的推理階段和問題，採用不同的推理機制，將rbr / cbr推理與模糊矩陣推理技術相結合，易於實現不精確推理中問題的求解策略；利用人工智慧技術，結合cad / cae手段，是kbe設計方法比較可行的一種實現方式。Further, in light of the mathematic functions among price, efficiency and equity, the effects / impacts of water pricing methodologies on efficiency and equity in water resources reallocation have been analyzed, the results are that different pricing methods have distinguish impacts on efficiency for water resources uses while they have few impacts on equity for incomes due to reallocation of water resources. fourthly, because the regional water resources have some features of river basin, an integrated water resources management ( iwrm ) has been suggested for the efficient management of regional water resources, where the basic criteria and intensions of iwrm have been analyzed. in order to the iwrm for regional water resources, the enabling environments, the institutional roles and the management instruments will be needed
再根據交易中的水價與效率及公平性關系的數學模型，分析不同的水價制定方法對水資源再分配（水權交易）的效率與公平性影響，提出的不同的定價方法對水資源使用效率有顯著影響，而對公平性基本沒有影響；針對區域水資源具有流域特徵的實際情況，提出了區域水資源綜合管理（ iwrm ）的模式，分析了iwrm的基本原則和包含的內容，進行了為實施iwrm的關鍵措施和體制安排，要實現區域水資源的綜合管理就必須具有寬松的環境、充分發揮管理機構的作用和靈活運用先進的管理手段；根據區域水資源的特點和可持續利用原則，進行了區域張仁田:區域水資源可持續利用研究水資源開發利用戰略方針的研究，按照制定的19項戰略方針，對一特定的區域進行了不同水用戶水資源需水量的中、長期預測，其中包括生態環境需水量，並採用iqqm模型進行供需平衡分析，提出在工程設施保證、技術措施和體制及法律保障到位的情況下，遠期能夠實現供需平衡。分享友人
