交付周期 lead-time

交付周期是指从订货到交货的时间，有时也说成是lead-time range。

Lead time: the lag between when an order is placed and the item is delivered.

在车间里它通常被称为“大门到大门”时间。这个概念还可以应用于产品从开始设计到结束的过程。为了降低制造成本，厂商会想办法 缩短交货周期（reduce / shorten the lead-time），而购货方则要跟进交付周期（follow up the lead-time）。

A lead time is the latency between the initiation and completion of a process. For example, the lead time between the placement of an order and delivery of new cars by a given manufacturer might be between 2 weeks and 6 months, depending on various particularities. One business dictionary defines "manufacturing lead time" as the total time required to manufacture an item, including order preparation time, queue time, setup time, run time, move time, inspection time, and put-away time. For make-to-order products, it is the time between release of an order and the production and shipment that fulfill that order. For make-to-stock products, it is the time taken from the release of an order to production and receipt into finished goods inventory.

例句1

Airbus senior vice president Brian Fleet said that having this facility close to the FALC is the most efficient industrial solution which will save transportation costs, reduce lead-time and risks in handling, and ensures quicker response time to our customers.

空客高级副总裁布莱恩•弗里特表示，配备达到空客中国总装线（FALC）标准的设备是最有效的工业解决方案，这可以节约运费，缩短交付周期，降低操作风险，并确保能尽快给客户回应。

例句2

A conventional definition of lead time in a supply chain management context is the time from the moment the customer places an order (the moment the supplier learns of the requirement) to the moment it is ready for delivery. In the absence of finished goods or intermediate (work in progress) inventory, it is the time it takes to actually manufacture the order without any inventory other than raw materials.

在供应链管理环境中，交付周期的传统定义是从客户下订单的时刻(供应商了解需求的时刻)到准备交货的时刻。在没有成品或中间(在制品)库存的情况下，这是在没有除原材料以外的任何库存的情况下实际制造订单所需的时间。

例句3

In the manufacturing environment, lead time has the same definition as that of Supply Chain Management, but it includes the time required to ship the parts from the supplier. Shipping time is included because the manufacturing company needs to know when the parts will be available for material requirements planning purposes.

在制造环境中，交付周期与供应链管理中的定义相同，但它包括从供应商处装运零件所需的时间。运输时间包括在内，因为制造公司需要知道零件何时可用于物料需求计划。

例句4

As the definition indicates, any task, project, or assignment has a lead time. The period between a manager delegating a task to their employee completing the task is a lead time, as is the amount of time it takes for a contractor to fulfill their obligations to their clients.

正如定义所示，任何任务、项目或分配工作都有一个交付周期。经理将任务委托给完成任务的员工之间的时间是一个交付周期，这是承包商履行其对客户的义务所需的时间。
