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In this dissertation, two kinds of optimization, methods are proposed. firstly, only these linking weights corresponding to the control rules that affect the control performance significantly are updated in order to reduce the compute works and speed up the training progress. secondly, the updating step is adjusted adaptively in accordance with the error and the change of error of the system based on the t - s model to get better performance
針對模糊神經網路控制器一般存在著在線權值調整計算量大、訓練時間長、過度修正權值可能導致系統劇烈振蕩等缺點，提出了兩種模糊神經網路控制器的優化方法：在線自學習過程中僅對控制性能影響大的控制規則相關的權值進行修正，以減小計算量，加快訓練速度；基於t - s模糊模型，根據偏差及偏差變化率大小動態自適應調節權值修正步長，抑制控制器輸出的劇烈變化，避免系統發生劇烈振蕩。When the paper uses the optimization regulation, it divides the management time into " t " stages according to ten days to make up the decision having many stages of the reservoir ' s optimization regulation, and it takes the reservoir ' s retain quantity of water or retain status of water and confiscated quantity of water a s condition variable, takes the water quantity of drawing off or quantity of electricity as decision variable. when the confiscated quantity of water can be known or be forecasted in every stage during the period of management, that is to say the confiscated water process can adopt the determined process, we can make up determine dynamic plan model with many stages and take the minimal lacking water as objective function
在動態規劃方法中把水庫的整個調度期，按句劃分為t個時段，以水庫的蓄水量s或蓄水位z和入庫水量q作為狀態變量，以水庫放水量q或電站出力n或發電量e作為決策變量，構成一個多階段決策過程，當計劃調度期內各時段的入庫徑流量已知或可以預報，即入庫徑流過程可以採用確定性徑流過程時，分別按缺水量d最小作為目標函數建立多階段確定性動態規劃數學模型。On such a basisthe commonly used monomial error accumulating totals correction method is introduced. the author proposes a coordinate transformation method to deal with its drawbacks of maths model imperfection, not applicable to lange - angle deviation and adding to the difficulties of equipment. while orientating the order of matrices according to the principle of the accordance between coordinate ' s rotating order and the physical process of device measuring, a strict maths model of the influence of axis system deviation on surveying angles is concluded and the corresponding correction method is induced. its far - reaching meanings are as follow : ( 1 ) the maths model of the influence of axis system deviation on surveying angles established by the new method is concluded after considerations for the three deviations simultaneously. changes under all circumstances are included, so it is theoretically a perfection of maths method

具體來說，在機理層面上，揭示高強度人類活動作用下的流域水循環及其伴生過程演變機理與規律；在模型方法層面，構建流域「天然人工」二元水循環及相關過程綜合模擬系統，形成水資源高效利用的基礎理論與方法；在應用基礎層面，提出缺水地區水資源高效利用和水循環整體調控的定量標準與模式。The technological risk is shown as selecting type mistake of the software and the system supplier ' s choice risk mainly ; transform risk display and means the risk appeared in order to change and manage various kinds of required management ideas of the means, management way, and in order to meet the needs of erp system, revitalize risks of organizing brought to institutional framework and business procedure ; control project risk display to implement cycle lengthen, implement cost increase, implementation quality and implement result up to goal preconcerted ; human resources risk show as lack effective consultant of implementation, lack the risk with staff of the implementing ability mainly
技術風險主要表現為軟體選型錯誤以及系統供應商的選擇風險；變革風險主要表現指為改變管理手段、管理方式所要求的各種管理觀念轉變所出現的風險，以及為了適應erp系統的需要，對組織結構以及業務流程進行重新調整所帶來組織風險；項目監控風險主要表現在對實施周期延長、實施成本的增加、實施質量以及實施效果沒有達到預定的目標；人力資源風險主要表現為缺乏有效的實施顧問指導、企業缺乏具有實施能力的員工的風險。The simulation results indicate that the parallel robot control can achieve much better effect than the traditional method by means of fuzzy control only if the abundant control experience and correct inference rules are available. as the simulation result showing, the anfis achieves the same satisfying effect with successful fuzzy control without requiring any control experience. the anfis can adjust the parameters of fuzzy inference system automatically and eliminate the influence of interfere signal on the base of adequate training samples
在缺乏實驗條件的情況下，通過對不同控制策略的模擬比較研究，說明了在具備系統的先驗知識和成熟的模糊規則的基礎上，對並聯機器人採取模糊控制能取得比採取傳統控制要好得多的效果，而anfis則能在毫無經驗的情況下，通過自動調整隸屬函數參數，自動建立符合系統變量特徵的控制模型和模糊推理規則，並能夠排除噪聲等干擾信號的影響，取得了與依賴專家知識進行控制一樣的效果，這也是模糊神經網路控制的優勢所在。Because there are some shortcomings on tuning the parameters of conventional pid controller, which include the difficulty to make sure the direction of tuning, the possibility to cause the crash of system and the requirement of the system ' s model parameters, a new self - tuning algorithm of pid based on wavelet is proposed in this paper, which is using some wavelet items to describe the state of system through studying the connection between the step response of system and the wavelet transform of the step response and simulating it by use of matlab
由於常規pid控制器參數調整中存在不少缺陷，如調整方向難以確定，容易引起系統崩潰，有些方法需要知道預先確定系統模型參數等。針對這些情況，本文通過研究小波變換的特點以及控制系統單位階躍響應和響應的小波變換之間的關系，在應用hatlab軟體進行了大量模擬研究的基礎上，找到了表徵系統狀態的小波指標，提出了一種基於小波變換的pid參數自調整演算法，為研究小波變換在控制領域的應用提供了新的思路。分享友人
