  1. 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
  2. Is acknowledged as an effective model for obtaining standardized and repeatable results ; the higher the level you achieve, the more notable the cost savings

    是公認的可以獲得標準可重復的結果的有效模型，您所達到的級別越高，成本節省的越多。
  3. By default, mysql uses the repeatable read isolation level for all transactions

    默認情況下， mysql對所有事務使用repeatable read隔離級別。
  4. Specifies that a scan is performed with the same locking semantics as a transaction running at repeatable read isolation level

  5. Transactions must be run at an isolation level of at least repeatable read to prevent lost updates that can occur when two transactions each retrieve the same row, and then later update the row based on the originally retrieved values

    當兩個事務中的每個事務都要檢索相同的行，然後又根據最初的檢索值更新行時，可能發生更新丟失。此時，事務必須至少以的可重復讀的隔離級別運行，以防止更新丟失。
