We have improved the reserves valuation method with several interest models. it uses a new mathematical method to analyze the reserves of the risk caused by the fluctuations in interest rate, and enables a new way to the risk managements of interest rates in insurance companies
本文通過對傳統條件下準備金提留演算法進行改進，以及選擇適當的利率模型，實現了montecarlo模擬在準備金分析上的實證應用，提出了在隨機利率條件下，利率風險準備金提留的一種比較新穎的數理方法。 -
According to the principle i. e. the investor obtains only the expected minimum benefit when npv is zero, based on the analysis of various factors effecting the cash flow of gas investment, the parameters related with the reserves are expressed as the function of reserve scale, and the mathematical model is developed to determine the gas minimum economic resources taking the resources as a variable and given npv is zero, which pro vides a decision making method for gas exploration invest merit
根據投資凈現值為零時投資者只獲得最低期望收益的原理，在分析影響天然氣投資現金流量各因素的基礎上，將與儲量相關的參數表示為儲量規模的函數，並以儲量規模作為變數通過令凈現值為零得到確定天然氣最低經濟儲量規模的數學模型，從而為天然氣勘探投資提供一種決策方法。 -
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。
