  1. This paper takes mobile engineering department equipment management of daqing petrochemical parent company as an example, and studies the design and application of equipment management system of daqing petrochemical parent company, for the implement of computerizing the equipment entire process management with the equipment management system and completing the synthesis management, the records management, the expense management, the fixed asset management, the specialized management and the information management with the computer system and making in the manual management some qualitative and stochastic ingredients transforming into the quantitative standard management. so it guarantees that we can perform advanced predicting management in the entire process of the matter movement and the value movement of equipment and complete the equipment servicing transition from the compulsory servicing and afterwards servicing to the preventive servicing, improving work quality, efficiency and modernized degree which the equipment manages and assisting enterprise ’ s equipment management decision - making and the whole realization of management goal and enhancing the enterprise ’ s interior equipment utilization and realizing its maximum profit

    本文以大慶石化總廠機動工程部的設備管理為例，對大慶石化總廠設備管理系統的設計與應用進行研究，旨在通過設備管理系統實現設備全過程管理計算機化，由計算機系統來完成設備的綜合管理、檔案管理、費用管理、固定資產管理、專業管理及信息管理，使人工管理中一些定性的、隨機的成分轉變為定量的規范的管理，保證大慶石化總廠對設備的物質運動和價值運動的全過程實行先進的可預知性管理，並逐漸將設備維修從目前的以強制性維修及事後維修為主過渡到以預防性維修為主，提高設備管理的工作質量、效率和現代化程度，輔助企業的設備管理工作決策及經營管理目標的整體實現，提高大慶石化總廠內部設備的利用率及實現其最大的經濟效益。
  2. With dramatic advance and wide application of the internet and information systems, we can easily attain large quantities of data that is also in rapid increment daily. thereby it becomes impractical to handle these data manually. we wish that computers can automatically process these data and extract potentially useful knowledge from them to help us arrange managements and make decisions

    隨著網際網路和信息系統的迅猛發展和廣泛應用，人們可以輕易地獲得海量的數據，並且這些數據還在日益不斷地增長中，對這樣的數據仍然採用傳統的人工處理方法變得不切實際，於是希望計算機能夠自動地幫助我們處理這些海量的數據，並提取出隱含的有價值的知識，輔助管理和決策，這就需要研究者對機器學習，特別是數據庫知識發現作更加深入和廣泛的研究。
  3. 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。
  4.
