ortools.constraint_solver.pywrapcp.GlobalVehicleBreaksConstraint Class Reference

Detailed Description

GlobalVehicleBreaksConstraint ensures breaks constraints are enforced on
all vehicles in the dimension passed to its constructor.
It is intended to be used for dimensions representing time.
A break constraint ensures break intervals fit on the route of a vehicle.
For a given vehicle, it forces break intervals to be disjoint from visit
intervals, where visit intervals start at CumulVar(node) and last for
node_visit_transit[node]. Moreover, it ensures that there is enough time
between two consecutive nodes of a route to do transit and vehicle breaks,
i.e. if Next(nodeA) = nodeB, CumulVar(nodeA) = tA and CumulVar(nodeB) = tB,
then SlackVar(nodeA) >= sum_{breaks [tA, tB)} duration(break).

Member Function Documentation

DebugString()

ortools.constraint_solver.pywrapcp.GlobalVehicleBreaksConstraint.DebugString

(

self

)

Reimplemented from ortools.constraint_solver.pywrapcp.Constraint.

Definition at line 6295 of file pywrapcp.py.

InitialPropagateWrapper()

ortools.constraint_solver.pywrapcp.GlobalVehicleBreaksConstraint.InitialPropagateWrapper

(

self

)

This method performs the initial propagation of the
constraint. It is called just after the post.

Reimplemented from ortools.constraint_solver.pywrapcp.Constraint.

Definition at line 6301 of file pywrapcp.py.

Post()

ortools.constraint_solver.pywrapcp.GlobalVehicleBreaksConstraint.Post

(

self

)

This method is called when the constraint is processed by the
solver. Its main usage is to attach demons to variables.

Reimplemented from ortools.constraint_solver.pywrapcp.Constraint.
