To aid in this process of model description and comparison, the CISNET has developed the Model Profiler, an Internet-based application. Each CISNET team has a private model profile Web site on which it maintains model profile information and controls what parts of the profile are shared with other teams. By using a core documentation format that is the same for each group, the published profile information can be compared among models. The system allows modelers to describe their models, and allows interested readers to read about, compare, and contrast simulation models.
