I have made a computer simulation, which is a model of a machine process step in a real factory. This factory keeps track of certain KPIs (key performance indicators), like utilization (% of time in use), throughput (#orders per hour), and lateness (% of orders processed too late)
My model also computes these KPIs. The values typically differ slightly, but I would like to know whether these discrepancies are acceptable.
How would I be able to check this? Is there a specific method I could use?
Example values: Utilization model: 81.5%, 79.2%, 90.2%, 87.6% Utilization actual situation: 84.7%, 77.6%, 84.3%, 85.5% We are talking about a minimum of 500 orders daily, to give you an impression, all resembled in just 3 KPIs.
