Simulations enables the user to test the DCR graphs and verify that the process works as expected.

Render graph while simulation

When simulating a graph the DCR graph is shown and updated during simulation.

Simulation without rendering

Starting from version 1.3 we now support simulations without rendering the graph. Instead we now focus on displaying the task list, log and swim lane of the simulation as illustrated below.

Simulation with swim lane
Non-technical users find this model easier to understand as the focus is on the tast available rather than the rules as displayed in the DCR graph.

Save simulations

When ending a simulation the user is asked if he wish to save the simulation. Simulations can be saved for documentation and analysis purpose. The Document generator can be used to output your graph as a Word or PDF document and the document will include representative graphs.

Save Simulation
When saving a graph you'll be asked to indicate whether the graphs is
  • a happy path
  • neutral
  • an unhappy path The term "a happy path" is often used in the busines process community to refer to the fastest or simplest or even sometimes naive execution of your process. The happy path often has value as it makes it easier to understand the process.

An un-happy path is something that should not happen, e.g. imagine an expense report process where you can pay the employee before manager approval. This is an un-happy path, something that should not be possible. By describing un-happy paths the tool can analyze the graph and ensure this behavior is not possible. We're currently working on this tool.

The videos below show how to simulate a simple graph and how to simulate graphs with auto users:

Simulation history

When you end each simulation you're asked if you would like to save your simulation for later analysis or usage.

The Simulation History displays the saved simulations:

Simulation History
Simulations that are representative is included in the documentation about the graph.

When clicking on a saved simulation you can replay the simulation and see the swimlane diagram.
