Simulation Results for a Scenario
When the parameters of the various process objects have been entered, you can run the simulation.
The Simulation Outputs property page displays:
• The Average Cost of processing an instance. It includes the cost of tasks and the cost of resources.
This cost is obtained by dividing the Total execution cost of the process by the number of instances processed. The Total execution cost of the process is the sum of the resource costs plus the sum of the costs of each task. See Results for tasks.• The Average performing time is the average task execution time for each instance. This time therefore includes the waiting time and the effective working time for each of the tasks performed by an instance.
Global Results
In addition to Average cost and Average actual work time, the overall results show:
• The Average processing time corresponds to the average time spent by an instance to go through the whole process. This time therefore includes waiting time, effective working time and downtime due to scheduling.
• The number of Instances processed.
This result must be identical to the number of instances specified at the start of the simulation.Results for tasks
The results for the tasks are given in seconds. They are also available in the form of a report. See Scenario Reports.
The results of a simulation for each task are:
• The Average performing time is the average execution time for a task. This value includes the average time declared at the input to perform the treatment plus the average waiting time.
• The Average queuing time is the average time spent waiting for instances arriving earlier to be processed by available resources. This time does not include any possible interruption time.
• The Average interruption time is the time spent waiting for the resource performing the task to become available again after a schedule-related interruption.
• The number of Instances processed by the task.
Note that the Total cost of a task is the unit cost of the task multiplied by the number of instances it has processed.
Results for resources
The Resources Results displays for each resource its Utilization.
Utilization is the percentage of time a resource has been occupied out of the total time allocated to it. Note that the Total cost of a task is the hourly cost of using the resource multiplied by the time the resource has been occupied.
