Limitations
The specific simulation software and techniques available in 2002 might differ from current standards. The focus was on maintenance systems, which may have unique characteristics.
Reliability & validity
The reliability of the findings is based on a systematic review of literature. Validity is strengthened by the expert evaluation of simulation factors, though it is limited by the scope of the reviewed literature and the time of publication.
Think critically
How might the increasing complexity of simulation software and hardware influence the perceived need for rigorous statistical validation?
Design Principles
"The fidelity and reliability of simulation outputs are directly proportional to the rigor applied in model verification, validation, experimental design, and output analysis."
Simulation is a powerful tool for optimizing complex systems like maintenance operations. However, without proper verification, validation, experimental design, and output analysis, the insights gained can be misleading, leading to poor decision-making in production and resource allocation.
What This Means for Your Design
When you use computer simulations to test ideas for a product or system, make sure you check that the simulation itself is accurate and that you've tested it in a way that gives you trustworthy results.
