A hierarchy of the credibility assessment is introduced and the state-of-the-art survey is presented with respect to this hierarchy. A glossary is provided to alleviate the lack of standard terminology. The future research calls upon looking at the <q>global picture</q> when conducting a simulation study and being concerned with all of the eleven credibility assessment stages not just model validation and programmed model verification.application/pdfenIn CopyrightTechnical reportTR-86-31http://eprints.cs.vt.edu/archive/00000038/01/TR-86-31.pdf
