Multiple instance sub process dialog box

Multiple instance sub processes

A "MultipleInstanceSubProcess" is a repetitive SubProcess. Unlike "ActivityLoopingSubProcesses", several parallel instances of a given "MultipleInstanceSubProcess" can exist.

The "MultipleInstanceSubProcess" dialog box contains three tabs: "Common", "Simulation" and "Parameter".

The "Common" tab of the "MultipleInstanceSubProcess" dialog box

The "Common" tab of the "MultipleInstanceSubProcess" dialog box is used to enter general information relative to a "MultipleInstanceSubProcess".

The "Common" tab of the "MultipleInstanceSubProcess" dialog box

Key:

· "Name": This field represents the name of the MultipleInstanceSubProcess.

· "IsTransaction": This field is a boolean indicating whether or not the MultipleInstanceSubProcess behaves like a transaction.

· "AdHoc": This field is used to determine whether the activities contained in the MultipleInstanceSubProcess are controlled and sequenced in a particular order.

· "Ordering": This field is displayed when the "AdHoc" field is set to "True". The "Ordering" field is used to define the type of sequencing of a Multiple InstanceSubProcess' sub activities. It can have one of the following values:

o Sequential

o Parallel

· "Condition": This field contains an expression representing the stop condition of the loop.

· "FlowCondition": This field is used to define the method used to transfer data between the different instances of the loop. It can have one of the following values:

o None

o One

o All

o Complex

The "Simulation" tab of the "MultipleInstanceSubProcess" dialog box

The "Simulation" tab of the "MultipleInstanceSubProcess" dialog box is used to enter information relative to the simulation of a MultipleInstanceSubProcess.

The "Simulation" tab of the "MultipleInstanceSubProcess" dialog box

Key:

· "Status": This field represents the status of the MultipleInstanceSubProcess during a simulation. It can be determined when a process is executed by an execution engine and can have one of the following values:

o None

o Ready

o Active

o Cancelled

o Aborting

o Aborted

o Completing

o Completed

· "Start Quantity": This field is used to define the number of occurrences of a given MultipleInstanceSubProcess during a simulation.

· "Counter": This field is used by the execution engine to count the number of time a loop is carried out.
