 VehicleFleetManager vehicleFleetManager,
 StateManager stateManager,
 ConstraintManager constraintManager)

Method Details

setShipmentInsertionCalculatorFactory

public InsertionStrategyBuilder setShipmentInsertionCalculatorFactory(JobInsertionCostsCalculatorFactory shipmentInsertionCalculatorFactory)

setServiceInsertionCalculator

public InsertionStrategyBuilder setServiceInsertionCalculator(JobInsertionCostsCalculatorFactory serviceInsertionCalculator)

setBreakInsertionCalculator

public InsertionStrategyBuilder setBreakInsertionCalculator(JobInsertionCostsCalculatorFactory breakInsertionCalculator)

setInsertionStrategy

public InsertionStrategyBuilder setInsertionStrategy(InsertionStrategyBuilder.Strategy strategy)

setRandom

public InsertionStrategyBuilder setRandom(Random random)

setRouteLevel

public InsertionStrategyBuilder setRouteLevel(int forwardLooking,
 int memory)

setRouteLevel

public InsertionStrategyBuilder setRouteLevel(int forwardLooking,
 int memory,
 boolean addDefaultMarginalCostCalculation)

setFastRegret

public InsertionStrategyBuilder setFastRegret(boolean fastRegret)

setPositionBasedRegretK

public InsertionStrategyBuilder setPositionBasedRegretK(int k)

Sets the number of positions to consider for position-based regret.

Parameters:

k - number of positions (-1 or Integer.MAX_VALUE for all positions)

setTopRoutesToExpand

public InsertionStrategyBuilder setTopRoutesToExpand(int m)

Sets the number of top routes to expand for position-level analysis in fast mode. Routes beyond this count are only considered at route-level (best position only).

Parameters:

m - number of routes to expand (default: 3)

setLocalLevel

public InsertionStrategyBuilder setLocalLevel()

setLocalLevel

public InsertionStrategyBuilder setLocalLevel(boolean addDefaultMarginalCostCalculation)

considerFixedCosts

@Deprecated
public InsertionStrategyBuilder considerFixedCosts(double weightOfFixedCosts)

Deprecated.

This method no longer has any effect. Fixed costs are now handled via IncreasingAbsoluteFixedCosts and DecreasingRelativeFixedCosts added as soft route constraints to the ConstraintManager. See Jsprit.Builder for an example.

setActivityInsertionCostCalculator

public InsertionStrategyBuilder setActivityInsertionCostCalculator(ActivityInsertionCostsCalculator activityInsertionCostsCalculator)

setConcurrentMode

public InsertionStrategyBuilder setConcurrentMode(ExecutorService executor,
 int nuOfThreads)

build

public InsertionStrategy build()

setAllowVehicleSwitch

public InsertionStrategyBuilder setAllowVehicleSwitch(boolean allowVehicleSwitch)
