In standard VRP problems, a node (pickup or drop-off) typically has a single time window defined by opentimets and closetimets. However, in many real-world scenarios, a location might be accessible during multiple disjoint time intervals. For example, a warehouse might be open for deliveries from 0800 and then again from 1400, closing for a lunch break in between.

The Capacitated Vehicle Routing Problem with Time Windows (CVRPTW) extends the classic VRP by incorporating two key real-world constraints: vehicle capacity and time windows. Time windows, which restrict when a customer can be serviced, are crucial for modeling realistic scenarios and significantly impact solution feasibility and cost.
