在理想的电子商务环境中，当安排客户订单并计算出发货日期时，应立即保留可用性，而不能用于将来的订单。然而，实际上，用于调度订单的可用性数据不是真实的时间可用性（物理可用性），而是存储在IT系统中的可用性信息（系统可用性）。IT系统中的可用性数据（可用性的静态视图）通常仅周期性地刷新（与真实的可用性同步），因为真实的更新数据库是非常昂贵的。由于这种可能不准确的可用性视图，某些订单无法在承诺的发货日期发货。因此，对于某些客户订单，产品的发货日期晚于承诺的发货日期，导致客户不满。因此，订单履行流程中的关键决策之一是适当平衡IT系统（例如，IT费用）和承诺发货日期的准确性。在这项工作中，我们研究了可用性新鲜率（IT系统）如何影响客户服务水平。我们开发的仿真模型有助于做出关于可用性更新率的关键业务决策，并避免昂贵的IT投资。
In an ideal e-business environment, when a customer order is scheduled and a ship date is computed, the availability should immediately be reserved and not be available for future orders. However, in reality the availability data that are used for the scheduling the orders are not real time availability (physical availability), but they are availability information stored in an IT system (system availability). The availability data in the IT system (static view of availability) is typically refreshed (synchronized with real time availability) only periodically since it is very expensive to update the database in real time. Due to this potentially inaccurate view of the availability, some orders cannot be shipped on the promised ship date. Therefore, for certain customer orders, products are shipped later than the promised ship date resulting in customer dissatisfaction. Therefore, one of key decisions in order fulfillment process is to properly balance IT system (e.g., IT expense) and accuracy of promised ship date. In this work, we study how availability fresh rate (IT system) impacts customer service level. The simulation model we develop helps making critical business decision on refresh rate of availability, and avoiding expensive IT investment.
