OptimizeToursRequest 会应用以下限制条件：
- 装运，这会影响装运方式
- 车辆，会影响车辆路线的计算方式
- 在全球范围内，这同时影响了车辆和货运。
本指南重点介绍一个基本的装运限制条件，即时间范围。
时间窗口是您在
OptimizeToursRequest 消息（REST、gRPC），以便指定
对配送活动施加时间限制。这种限制会影响
配送时间、配送方式以及车辆分配
。有了这些约束条件，优化器会优先考虑
最能满足运送时间限制的车辆。
配送限制：时间范围
您可以指定何时可在Shipment.VisitRequest自提或送餐
消息，如下所示：
具有时间范围限制的请求示例
此处的示例展示了三种不同的运单，每一种都有自己的
送货时间。为简单起见，此示例将时间范围设置为 deliveries
，但时间范围也可应用于上车点。可以设置多个时间范围
但在本示例中，每次提交时只使用一个 VisitRequest。

具有时间范围限制的响应示例
在示例响应中，车辆的开始时间和结束时间为 17:35:50，
分别是 18:17:24这些时间反映了优化器最大限度地缩短时间
必须操作请求中指定的车辆（如 costPerHour），
满足所有时间范围限制条件的要求。使用 17:35:50 作为开始时间
使车辆无需在上门地点等待
的访问时间窗口开始计算。这在响应中显示为零 waitDuration
值。

已为车辆的 visits 订购时间范围，以便采用
最早的时间范围会优先投放。
shipments[2]在 17:50 送达shipments[1]在 18:00 送达shipments[0]在 18:07 送达
示例请求指定了硬性时间范围限制，要求
可在这些时间范围内完成的交付。如果完成运单的
VisitRequests不可行，或者
优化程序会跳过装运。如果运单的
penaltyCost 时，优化器会将其添加到响应中报告的费用中
metrics。否则，skippedMandatoryShipmentCount
OptimizeToursResponse 消息（REST、gRPC）增加。
如果您通过将“shipment[1]”的窗口移几小时而更改时间范围
则结果会有所不同，如下面的

在此示例中，较晚的时间段导致 shipment[1] 被跳过，
因为完成装运需要额外的车辆操作时间
超过发货的罚金。
shipment[1] 的处罚费用显示在 metrics.costs 中及其索引中
出现在 skippedShipments 中。
软性时间范围限制
如费用模型参数简要所述，您可以将时间范围应用于 软约束条件。软约束条件与硬性约束条件有以下不同：
- 硬性约束：不能违反，且优化器不提供 解决方案，即使这意味着跳过 送货。
- 软约束：可能会违反，这意味着优化器可能会 提供违反软约束的解决方案。不过，优化器 并会针对所有违规行为支付费用。您需要以 额外属性，通常是 。
通过使用 softStartTime 或 softEndTime（而不是
startTime 或 endTime，通过设置
costPerHourBeforeSoftStartTime 或 costPerHourAfterSoftEndTime。
在自提或配送期间使用软时间范围限制 在指定时间范围内，但不在该时间范围内自提或送餐 绝对必填。您可以结合使用硬时间窗口约束和软时间窗口约束 以表达业务目标例如：
- 硬性时间范围：表示客户的营业时间，例如： 上午 9 点至下午 5 点。
- 软时间窗口：指明送货或自提的时间范围 与发送给客户的通知匹配，例如上午 9 点至下午 1 点。
在本示例中，之前因配送时间而跳过的运单 开始太晚的开始时间限制会降低。另一个 每个运单都有其时间范围结束时间也随之减少

仅具有硬性时间范围限制的样本完全跳过了
shipment[1]，减少其送货时间范围会导致商品送达
早于其时间范围开始时间。同样，
其他运单允许 shipment[2] 在其时限过后送达
结束。
同时，费用和总运费都发生了变化：
totalCost：从 81.283 下降到 64.797- 已完成的运单总数：增加了 2 个到 3 个
优化器找到了一个更便宜的解决方案，因为 与上一个示例相比，限制放宽了。
最后，metrics.costs 属性还包含一个新键，用于指示
根据约束的乘积和
错过了送货时间。具体来说：
costPerHourBeforeSoftStartTime/2.0 和- 从实际投放到时间段开始的时间间隔： 2.83583 小时
结果：
model.shipments.deliveries.time_windows.cost_per_hour_before_soft_start_time：
5.6716666666666669。
通过这些指标，您可以进行费用分析，
