Defining Process Simulation Properties

The PowerDesigner atomic process is mapped to the SIMUL8 work center, whereas the composite and implemented by processes are mapped to the SIMUL8 component.

The following simulation properties only apply to the atomic process; composite and implemented by processes do not have SIMUL8 extended attributes.

From the Simulation tab of the process property sheet, you can display the following SIMUL8 extended attributes:

Name

Internal code

Value

Description

Finance capital cost

FinanceCapitalCost

0

Capital cost. At the end of simulation, the accumulated data on the flows of money are displayed in the SIMUL8 Finance > Income Statement window

Finance cost by time unit

FinanceCostByTimeUnit

0

Usage cost of the process by time unit

Cost by unit

FinanceCostByUnit

0

Usage cost of the process by work unit

Replicate

Replicate

1

Effective number of processes performing the same tasks. Using the Replicate number is a way to copy the process

Priority

ResourcePriority

50%

If two processes both require the same resource before they can start work, the process with the highest priority will be given the resource first (from 0 to 100)

Release

ResourceRelease

true

If false, it means that resources must wait with the work item if the process is "blocked" (i.e. if it cannot send the work items to the next simulation object)

Bound lower

TimingBoundLower

10

Lower bound for the uniform timing distribution type. Samples from a uniform distribution are equally spread between the lower bound and the upper bound

Bound upper

TimingBoundUpper

11

Upper bound for the uniform timing distribution type. Samples from a uniform distribution are equally spread between the lower bound and the upper bound

Distribution

TimingDistribution

Average

Statistical distributions provide a method of simulating the variations that occur in timing in the process. Other values: Exponential, Fixed, Normal, Uniform

Standard deviation

TimingStandardDeviation

0

Standard deviation for the normal timing distribution type. For the average distribution type, this standard deviation value is set to: average value / 4

Note

For more information on how to display the process property sheet, see Process Properties.


  • The resource flow object supports the resource attributes of the process (resource min/max number, resource require)

  • Routing out properties cannot be modified, since they are set by PowerDesigner
