Problem Class |
The problem definition. It contains the Jobs to be assigned and the
Resources available to assign them to.
Inheritance HierarchyNamespace: VRSolver
Assembly: VRSolver (in VRSolver.dll) Version: 1.13.0.0
SyntaxThe Problem type exposes the following members.
ConstructorsProperties| Name | Description | |
|---|---|---|
 | JobPartsCount |
The total number of JobParts (not the number of Jobs).
|
| LeaveStartLocationAsLateAsPossible |
If true then resources leave their starting locations so as to
minimise any idle time at the first job i.e. leave later (start
location windows permitting). If false then the resource leaves the
starting location when the start location window opens. NB work time
starts when the resource leaves the starting location.
|
| MaxDrivingTime |
The maximum driving time for each resource.
(Set to less than zero to ignore this constraint).
This is a global setting and applies to all resources. To set a value
for an individual resource use MaxDrivingTime in the Resource class.
This is a hard constraint that will always be satisfied.
|
| MaxWorkTime |
The maximum work time for each resource.
The work time is the time from when the resource leaves the start
location until it returns to its end location.
(To ignore this constraint set it to a value less than zero).
This is a global setting and applies to all resources. To set a value
for an individual resource use MaxWorkTime in the Resource class.
This is a hard constraint that will always be satisfied.
|
| TotalDistanceWeight |
The weight for minimising total distance traveled by all resources.
The weight is per the unit of distance that is set in the TravelTime
matrix.
|
| TotalLatenessWeight |
The weight for minimising Lateness for jobs that have soft windows.
The weight is per minute.
|
| TotalWorkTimeWeight |
The weight for minimising the total working time for all resources.
The working time for a resource is the time from when the resource leaves the start
location until it returns to its end location.
This is a global setting which applies to all resources. To set a
weight for an individual resource use MaxWorkTimeSoftConstraintWeight in the
Resource class. The weight is per minute of work time.

Methods| Name | Description | |
|---|---|---|
 | AddJob |
Adds a Job to the problem.
|
| AddResource |
Adds a Resource to the problem.
|
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetJob |
Gets a Job using a Job ID.
|
| GetJobPart |
Gets a JobPart using a JobPart ID.
|
| GetResource |
Gets a Resource using a Resource ID.
|
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
 | Load |
Load a problem from a file.
|
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| Save(String) |
Save the Problem to a file.
|
| Save(String, Boolean) |
Save the Problem to a file.
|
| SaveAsByteArray |
Save the Problem to a byte array. The Problem is converted to
a JSON format and then the JSON format is converted to a byte array.
|
| SaveAsByteArray(Boolean) |
Save the Problem to a byte array. The Problem is converted to
a JSON format and then the JSON format is converted to a byte array.
|
| SetAllowAssign(String, String) |
Allows the Job to be assigned to the selected Resource if it
was previously not allowed by calling SetNotAssign.
|
| SetAllowAssign(Job, Resource) |
Allows the Job to be assigned to the selected Resource if it
was previously not allowed by calling SetNotAssign.
|
| SetFixAssign(String, String) |
Fix a job assignment to the selected resource i.e. the solver will ensure this
assignment is made and the job is not assigned to a different
resource.
|
| SetFixAssign(Job, Resource) |
Fix a Job assignment to the selected Resource i.e. the solver will ensure this
assignment is made and the Job is not assigned to a different
resource.
|
| SetNotAssign(String, String) |
Ensures the solver will not assign the job to the selected resource.
|
| SetNotAssign(Job, Resource) |
Ensures the solver will not assign the Job to the selected resource.
|
| SetTravelTimes |
Sets the TravelTime matrix.
|
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
Fields| Name | Description | |
|---|---|---|
 | Jobs |
The Jobs that have been added to the problem. To add new Jobs use
the AddJob(Job) method.
|
| Resources |
The Resources that have been added to the problem. To add new
Resources use the AddResource(Resource) method.
