This paper develops a deterministic inventory model for perishable items with a mixture of back orders and lost sales under inflation and time discounting, where the backlogged demand rate is dependent on the negative inventory level during the stock out period. the main differences from the existing related models are that the present model takes the maximum present value of profit in a repeatable order cycle as the objective function and proposes a more practical constraint of maximum customer - waiting time to ensure a proper customer service level. then the existence and the uniqueness of the solution to relevant systems are examined and a solution algorithm is shown to find the optimal replenishment policy. at last, some numerical examples are presented to illustrate the applicatioh of the model
本文建立了一種考慮通貨膨脹與時間價值的變質性物品的庫存模型，在模型中允許短缺發生且拖后的需求速率與在缺貨期間已經發生的缺貨量有關.和已有相關模型的主要區別在於本模型把一個可重復的訂貨周期內的最大平均利潤的凈現值作為目標函數，且增加了在缺貨期間最長顧客等待時間的限制，以確保庫存系統擁有較高的服務水平.然後討論了模型最優解的存在性與唯一性，並提供了尋求模型整體最優解的演算法.最後用實例說明了此模型在實際中的應用 -
This paper evaluates the underground water resources and its safe levels of miming, and then studies the availability of molepipe drainage, a kind of practical underground water regulation technique. starting with the elevation of underground water resources and a safe level of mining through variable system theory, this paper analyzes the conditions of underground water resources based on the well - studied determination method of determining the two hydrographical coefficients : rainfall infiltration replenishment rate and irrigation replenishment rate. then considering irrigation, rainfall, drainage and other related factors, a mathematical model is set up for the calculation of underground water storage, exploitation on water regulation
論文從灌區的地下水資源及其可開采量評價分析方面入手，在對兩個主要的水文地質參數即降雨入滲補給系數、灌溉入滲補給系數確定方法研究的基礎上，對灌區的地下水資源狀況進行分析，依據灌區的灌溉、降雨、排水條件及各種現狀因素，建立了地下水資源量計算的數學模型，西安理工大學工程碩士專業學位論文計算得到青銅峽灌區地下水的最大補給量和可開采量;另外對在開發利用地下水資源過程中的地下水位的調控進行了初步的探討，在銀北灌區開展對暗管排水調控地下水位的試驗研究。
