Most BPMN diagrams contain some tasks which involve decision-making which can be modeled in DMN. These tasks take input data acquired or generated earlier in the process and produce decision outputs which are used later in the process.

Enterprise Architect provides a model pattern to illustrate how DMN and BPMN integrate. Simply search the model patterns for the example called "DMN Delivery Cost Calculation". The BPMN Integrate with DMN Delivery Cost Calculation Example demonstrates how to integrate DMN's Business Knowledge Model into BPSim configuration. The right hand pane of the model pattern provides a detailed explanation to help you get started.

DMN specification's "Annex A. Relation to BPMN" defines the relationships between DMN and BPMN.

The specification can be download from: Decision Model and Notation
Enterprise Architect supports the integration of DMN into the BPMN model, via integration of DMN into BPSim Simulation in two ways:

• The Business Knowledge Model acts as a global function.
• Decision Service as a system to accept input and outputs.

Yes, it is possible to supply a dataset. For DMN simulation, each Item Definition can define multiple data sets and the user can select one for each Input Data for each simulation. In this way, the user can conduct a what-if analysis based on a variety of different input datasets.

To see an example of this process, use the model wizard and search for "BPMN Integrate with DMN Complete Example".

For BPSim integrated with a DMN model, the data set can be defined in BPMN 2.0's Data Object, please refer to the (DataObject Applicant Data and Requested Product, double click and view the property).

BPSim currently does not support recording the output. However, on completing the simulation, the user can "replay" to debug the model by viewing the simulation step by step.

BPSim defines a big range of distributions to suit real business scenario for probability configuration. The detailed list can be found here: https://www.bpsim.org/
Please refer to: 6.3.5 Distribution Parameters.

There is no concept of "weight" on a Sequence Flow in BPMN, however, condition parameters can be set on Sequence Flow and control the flow of process logically.

Please refer to the example "BPMN Integrate with DMN Complete Example", which defined two property parameters: Strategy and Routing.

• Property "Strategy" was assigned in task "Decide bureau strategy" and used in 3 Sequence Flows
• Property "Routing" was assigned in task "Decide routing" and used in 2 Sequence Flows

View the property parameters and references through: Double click the BPSim Artifact to open the "Configure BPSim" window | click "Configure" tab | click 4th button on the toolbar to open the "property parameters" dialog.
