The research paper is based on the the latest softwares of the managing inventory, its research subject is about simulating the most appropriate inventory quantity and ordering quantity by statisticing the probability of the random require quantity. its purpose is to provide the relied basement for determining the most appropriate inventory quantity and ordering quantity, the deterring policy quality will be raised, so the damage caused by unfit inventory quantity and the benefit of the entrerpreneur will be raised. the research method is by building the inventory management information system, the system includes automated management of parts entering and going out the datasbase. requesting the records of parts entering and going out the datasbase and displaying the sygonal when the inventory quantity is short out. computer calculating the fix period remaining, requesting remaining at any time and displaying if goods need ordering, all the partsof certain a product going out of basement and at the same time checking if the storaging quantity is enough. then simulating the most appropriate inventory quantity and ordering quantity simulating method is as follows : statisticing the random required quantity. calculating the probability, standing for the values with data range producing random data by function accordingly calculating the random required quantity. thenext step is simulating all the projects after pressing in the simulating conditions. finally selecting the best
本文通過分析國內外關于庫存管理軟體的發展情況,提出在線統計貨物出庫情況的基礎上利用模擬方法確定最優存儲方案,其目的是為制定合理的貨物安全庫存量和訂貨量提供可靠的依據,提高企業管理人員的決策質量,從而減小資金的佔用和缺貨損失,提高企業的經濟效益。通過研製庫存管理信息系統使庫存信息管理自動化,也就是實現貨物入出庫管理計算機管理、自動查詢貨物入出庫情況並在缺貨時給予提示、使用計算機貨物余額定期結算、貨物余額實時查詢並顯示是否需要訂貨、裝配出庫管理使得只要輸入需要裝配產品代號和數量,組成它的所有零件就會自動檢庫和出庫。然後對安全庫存量和訂貨量進行模擬,模擬方法是首先自動統計貨物在過去某一段時間內的需求量,計算出概率,用隨機數的范圍表示其概率數值的大小,利用隨機函數產生隨機數、從而間接的產生隨機需求量,給定模擬天數和其他模擬條件模擬各種方案,從眾多的存儲方案中找出最優存儲方案。Underlying the assumption that the stock price accords with the model of the stock price fluctuating sources, by comprehensivily applying the stochasitic differential theory and no - arbitriagc thcory, this paper, under the conditions that the risk - free rate r is constant or ito stochasitic process, successively works out the option pricing about the stock price model with that the short - term profit function is piecewise lecture function arid that one with that the short - term profit function is possion jump process, derivats counterpart partial differential equation of option pricing. the outcome states : 1. when the short - term profit function is unusual flunctuating sources bring out a piecewise lecture function, this amendment on the lognormal distribution model does not improve the option price, because this partial differential equation of option pricing is the same one underlying the lognormal distribution model ( see equation 2. 14 )
本文基於股價符合波動源模型的假設,綜合運用隨機微分理論等數學原理和無套利理論等金融理論,依此對短期收益率函數為分段階梯函數和possion跳躍過程的股價波動源模型分別在無風險利率是常數和隨機過程的條件下作了期權定價,推導出了相應的期權定價偏微分方程,結果表明: 1 、由異常波動源帶來的短期收益率函數是分段階梯函數時,這種對股價對數正態分佈模型的修正不能改善期權價格,因為基於這種模型的期權定價偏微分方程與基於股價對數正態分佈模型的期權定價偏微分方程完全相同(見方程2 . 14 ) 。In this paper, the pce principle, method and technical achievement of traffic engineering in domestic and overseas from 1940 to 1993 are analyzed, compared and evaluated. moreover, the use condition and limitation of the studying achievement are elaborated. based on it, in view of the complexity of the vehicle kinds and mixed traffic in domestic highway traffic, the physics method on influence space of vehicle is put forward according to the achievement of studying the road capacity and the mass traffic observation data of 177 section of highway
本文首先對1940到1993年以來,國內外在交通工程研究中涉及到的車輛當量換算系數計算的原理、方法和技術成果進行了分析、比較和評價,闡述了這些研究結果的使用條件和局限性。在此基礎上,鑒於我國公路交通中車種多,車型復雜以及混合交通等的特點,通過對我們以前研究通行能力積累的成果和實地177個不同路段所採集到的大量交通觀測數據的分析和研究,利用數理統計和隨機場理論,提出了一種汽車道路作用空間的物理分析方法來研究車輛當量換算問題。In this paper, through the statistical analysis of the random factors in the stage of sub - critical propagation of cracks, the statistical correlation equations between the two material coefficients are obtained and can be generalized. furthermore, it can be concluded that cracks propagation rate is influenced greatly by material coefficients in the condition considered in this study
本文主要通過對亞臨界裂紋擴展階段各種隨機因素的統計分析,找到了可以推廣應用的,體現兩材料系數之間具有強負相關性的統計相關式,並驗證了在一定條件下,材料系數是影響裂紋擴展速率的主要因素。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。分享友人
