Description

This object is new at ArcGIS 9.3.

Remarks

NAVRPSolver is a Network Analyst solver that computes an optimized set of routes for a fleet of vehicles to service a set of input orders. The NAVRPSolver can also honor time windows, multiple route capacities, travel duration constraints, route zone and route seed point constraints, specialties constraints, and paired order constraints. The NAVRPSolver honors all of the settings of the INASolverSettings interface except for IgnoreInvalidLocations. If invalid locations are present, the solver will return an invalid input error, along with the appropriate GP messages identifying each error.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

                                       AutomationException

Indicates the type of internal matrix to be created.

Remarks

The InternalODCostMatrixType property specifies a value of type esriNAODCostMatrixType. This enumeration constrains how the VRP solver uses and manages an internal NAODCostMatrixResult object during a Solve.

A client using the internal OD cost matrix pattern should set this property to esriNAODCostMatrixFull whenever the set of barrier locations, restrictions, usage of hierarchy or attribute parameter values have changed since the last Solve operation. This ensures that the internal OD cost matrix is fully recalculated based on any new barrier locations or solver settings. Otherwise, setting this property to esriNAODCostMatrixUpdate will ensure that the internal cost matrix is updated with new OD cost entries for locations added since the last Solve operation.

Remarks

The ExternalODCostMatrix property can be used to specify an externally-created NAODCostMatrixResult object or custom object that implements the INAODCostMatrix interface for use within the VRP solver Solve operation.

Remarks

The TimeFieldUnits property specifies the unit of time to associate with the time-based input and output field values of NAClasses within a VRP NAContext. Examples of such time-based fields include the ServiceTime field on the Orders NAClass and the CostPerUnitTime field on the Routes NAClass. This time unit need not agree with the time unit of the impedance cost attribute. For example, the client may use an impedance cost attribute based on minutes but use seconds for the time-based field values.

getDefaultDate

public Date getDefaultDate()

                           AutomationException

The date to use for time windows without dates.

Remarks

The DefaultDate property is used to specify the default date portion of date-based fields (where FieldType = esriFieldTypeDate) within the NAClasses of a VRP NAContext. Fields of type esriFieldTypeDate can actually be used to specify both date-time values (e.g., June 1, 2008, 8AM) and time-only values (e.g., 8AM). Time-only values will be interpreted by the VRP solver as having a date portion equal to the DefaultDate property value.

For example, if a date-based field value within a particular NAClass of a VRP NAContext is set as the time-only value 8AM and the DefaultDate property value is set as June 1, 2008, then the VRP solver will interpret this date-based field value as June 1, 2008, 8AM.

The DefaultDate property cannot be before January 1, 1900 or after December 31, 9999. By default, the DefaultDate property is set equal to the current date when the solver is created.

getCapacityCount

public int getCapacityCount()
                     throws IOException,
                            AutomationException

The number of dimensions for object sizes.

Remarks

Capacities are used to model cumulative quantity constraints on the routes. These constraints typically arise from physical measurements and limit the total pickup and/or delivery quantities of orders associated with a route. The CapacityCount property specifies the number of different capacities that are being constrained. For example, if you are constraining weight and volume, the CapacityCount would be 2. Following this example, a route feature with its Capacities field value set to “2000 500” would indicate that it can transport a maximum weight of 2000 units (pounds) with a maximum volume of 500 units (cubic feet). An order feature might have its DeliveryQuantities field value set to “10 5” indicating that the weight of the order is 10 and its volume is 5.

The units for capacities are not specified in the VRP solver; furthermore, the ordering of the capacities in the string is arbitrary. This means that within a VRP analysis, capacities always need to be listed in the same sequence (in this example, weight and then volume) among all routes and orders. The number of tokens in these strings cannot exceed the CapacityCount property value.

getTimeWindowViolationPenaltyFactor

                                                  AutomationException

The penalty factor for time window violation in the objective function.

Remarks

A time window violation occurs when a route arrives at an order, depot, or break after a time window has closed. The violation is the interval between the end of the time window and the arrival time. This property is used for calibrating time window violations within the solver objective function. For example, a penalty factor value of 5.0 means that a minute of time window violation increases the solver objective function value by the cost of five minutes of work time. The higher the penalty factor, the more the solver will favor solutions with smaller time window violations versus reducing overall route duration for the fleet. This penalty factor must be zero or positive, and cannot exceed one billion. The penalty influences the solver objective function during the optimization process, but is not included in the output route operating costs. The default value for this property is 1.0.

                                                AutomationException

The penalty factor for excess transit time in the objective function.

Remarks

Excess transit time is the amount of time exceeding the time required to travel directly between the paired orders. The excess time results from breaks or travel to other intermediate orders or depots between visits to the paired orders. This property is used for calibrating excess transit time between order pairs within the solver objective function. For example, a penalty factor value of 5.0 means that one minute of excess transit time increases the solver objective function value by the cost of five minutes of work time. The higher the penalty factor, the more the solver will favor solutions with less excess transit time between paired orders versus reducing overall route duration for the fleet. The penalty influences the solver objective function during the optimization process, but is not included in the output route operating costs. The default value for this property is 1.0.
