如何将时间窗口约束和容量约束添加到 VRP？

[英]How to add both time window constraint and capacity constraint to VRP?

原文 2019-01-25 09:37:09 7 1 python/ or-tools/ vehicle-routing

I have just started working on VRPs with Google's OR Tools.我刚刚开始使用 Google 的 OR 工具处理 VRP。 I would like to impose multiple constraints on my VRP ie instead of just adding just one among time window constraint or capacity constraint, I would like to have both the constraints to solve my problem without taking into account the cost.我想对我的 VRP 施加多个约束，即不是只在时间窗口约束或容量约束中添加一个，我希望在不考虑成本的情况下同时使用这两个约束来解决我的问题。 How to achieve this?如何实现这一目标？
