此示例展示了如何使用基本费用参数对分配给车辆的经停点的顺序进行基本优化。它可确保以最具成本效益的顺序在指定时间范围内访问所有停靠站。
示例请求
此示例请求包含以下关键参数：
populatePolylines和populateTransitionPolylines：将这些参数设置为true可获取车辆路线的编码多段线路径。globalStartTime和globalEndTime：定义必须完成所有活动的 24 小时时间段。如需详细了解时间窗口，请参阅时间窗口这一关键概念。shipments：定义三批货物，每批货物都从一个共同的仓库位置提货，并运送到一个唯一目的地。由于您未设置penaltyCost，因此所有配送都是强制性的。vehicles：定义一辆具有共同起点和终点的车辆。提供costPerKilometer和costPerHour，以指导优化器找到最便宜的路线。如需详细了解费用，请参阅费用模型这一关键概念。

示例响应
响应包含一个顶级 routes 字段，用于表示建议的路线，每辆车对应一条路线。由于本指南中的示例请求仅指定了一辆车，因此 routes 仅包含一条 ShipmentRoute 消息。

以下字段描述了完整的车辆路线：
visits：此数组按优化后的顺序列出了所有取货和送货。在此示例中，优化器确定最高效的顺序是先从配送中心取走所有三批货物，然后再进行配送。transitions：此数组列出了每次访问之间的行程段。由于所有三个上车点都在同一位置，因此前三个过渡的travelDuration为“0”。routePolyline：顶级折线表示车辆的整个路径，从起点到终点。您还可以在每个transition对象中找到表示各个行程段的较小折线。 注意：您可以使用交互式多段线编码器实用程序直观呈现这些多段线以及任何其他多段线。
