How to run a simulation

 
Quickstart tutorial 4-How to run a simulation
 

Introduction

Running a simulation enables you to observe the results of a process according to a specific set of inputs.

When you created your simulation snapshot, a new simulation profile was created for Quickstart Finance Loan Application (To Be) process. You can now run a simulation based on that profile. The simulation profile for this simulation was produced when you created the simulation snapshot. Therefore it will take its initial settings from the simulation preferences that you updated in a previous exercise.

The Loan Application (To Be) process determines whether a customer's loan request will be approved. Each application is passed into a particular path, depending on the approval decision. Regardless of which path is taken, a certain number of tasks will be performed for each application.

When you run a simulation, items called tokens arrive at the input of the process and move along the process connections, into and out of the activities that makes up the process. By default, the minimum number of tokens that are required for a single successful run of the process are set to arrive during simulation. In the case of this simulation, a single token is scheduled to arrive. You will change the number of tokens arriving for the simulation in a later exercise, but for now, you will run the simulation with a single token.

How to run a simulation

To run a simulation of the Loan Application (To Be ) process, complete the following steps: 
 
Step 1

Ensure that the Loan Application (To Be) simulation profile is open in the simulation editor. If it is not open, double-click the simulation profile in the Project Tree to open it.

Step 2

  1. At the top of the Attributes View, click the Simulation Control Panel tab. The Simulation Control Panel opens.
  2. On the Simulation Control Panel toolbar, click the Run icon. The simulation starts and runs until completion, based on the default attributes. Note the simulation animation shown in the Simulation editor as the data and control passes from one activity to another through the process flow.
  3. You can control the simulation by clicking the various icons in the Control Panel toolbar.
    1. To pause the simulation, click the Pause icon.
    2. To stop the simulation, click the Stop icon.
    3. To run the simulation in steps, click the Step icon. Note: You will not need to run simulations in steps in this tutorial. For more information simulation controls, including running your simulation in steps, see Simulation controls in the help documentation.

When the simulation is complete, the animation stops and the results of the simulation are displayed in the Simulation Control Panel, as in the following image on the right:

 

Data is displayed about the process as a whole, as well as the individual tasks and connections in the process. Click the Processes, Tasks, and Connections tabs to view the data generated in this simulation.

 

Later in this module, you will learn how to perform detailed analysis on your simulation results. First, you will learn how to set the attributes for specific simulations and their component tasks.
