Configuring and running simulation : Validating the simulation project
 

Validating the simulation project

The Simulation perspective provides an advanced validation framework, which lists common configuration errors for selected simulation components. You cannot run the simulation unless you rectify these errors.
From the Simulation Control Editor, you can identify the erroneous simulation components, which are highlighted with a red square; for instance, .
Table 72 lists the common validation errors, where they occur, and their resolution.

Simulation Project
The absolute start time is not specified.
Specify a relative start time for the At time option in the Scenario tab of the simulation project’s Properties view.
The absolute completion time is not specified.
Specify a relative stop time for the At time option in the Scenario tab of the simulation project’s Properties view.
Scenario
A scenario configured with system start time and absolute end time.
From the Scenario tab of the simulation project’s Properties view for the selected scenario, select any available option other than system time (for simulation start) and At time (for simulation stop).
Absolute start time for a scenario is greater than absolute stop time.
From the Scenario tab of the simulation project’s Properties view for the selected scenario, specify a relative time for simulation stop higher than the relative time for simulation start.
For a process with absolute start time, the scenario is set to system start time.
From the Scenario tab of the simulation project’s Properties view for the selected scenario, specify an absolute time for the simulation start.
Absolute start time for a scenario is greater than absolute start time for any of the added processes.
From the Scenario tab of the simulation project’s Properties view for the selected scenario, specify an absolute time for the simulation start lesser than the absolute start time for each process.
Process
The absolute start time is not specified.
Specify a relative time for the At time option in the Instances tab of the process’ Properties view.
Process instance count is unlimited with simulation stop time set to completion of process instances.
Specify a process instance count in the Instances tab of the process’ Properties view.
Process / Workstep
For Uniform randomizing method, the maximum duration is lesser than the minimum duration.
Specify the maximum duration for Uniform distribution type greater than the minimum duration.
Performer / Resources
Cost of the performer or resource is zero.
From the General tab for the added performer’s (individual, group, and adapter) and for the added resource’s (consumable and non-consumable) Properties view, specify value greater than zero in the respective cost fields.
Non-consumable Resource
Specified count of the resource is zero.
From the General tab for the added non-consumable resource’s Properties view, specify count greater than zero in the Availability box.
Consumable Resource
The resource has no defined unit of measure.
From the General tab for the added consumable resource’s Properties view, specify a unit in the Unit box.
Group Performer
The group performer has a virtual group size equal to zero.
From the Members tab for the added group’s Properties view, specify the virtual member count greater than or equal to one.
Path
The path contains only one workstep.
From the General tab for the defined path’s Properties view, specify the path length greater than one.
Workstep
The consumption count for an added non-consumable resource is greater than the available count.
From the Resources tab for the workstep’s Properties view, specify the count of the added non-consumable resource less than its available count.
