Defining Flow Simulation Properties

The PowerDesigner flow is mapped to the SIMUL8 route. The route is not an object but a symbol that is why it has no SIMUL8 properties. However, the queue object that is added to each route symbol during generation, has SIMUL8 extended attributes.

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

Name

Internal code

Value

Description

Add queue

AddQueue

True

Add queue on the flow. A queue is a place where work to be done can wait until appropriate resources or processes are available. If the source is the start object or the main simulation diagram, a queue is always added to prevent the loss of work items (display of an error dialog box during the simulation)

Capacity

QueueCapacity

-1

Maximum count of work items that can be in this queue (-1 = no limit). When the maximum count is reached, further items are blocked (stay in the objects that feed the queue)

Finance capital cost

QueueFinance CapitalCost

0

Capital cost of the queue. Financial results are displayed in the SIMUL8 Finance > Income Statement window

Finance cost by time unit

QueueFinanceCostByTimeUnit

0

Usage cost of the queue by unit and by time unit

Initial item count

QueueInitialItemCount

0

Initial count of items in the queue at the start of the simulation run

Min wait time

QueueMinWaitTime

0

The minimum time a work item must stay in the queue

Routing out percent

RoutingOutPercent

100

Only for a decision output flow: the work items coming from the decision are distributed to destinations according to percentages you specify
