The Model Description Documentation Recommended Practice for Ground Vehicle System and Subsystem Simulation defines the recommended information content to be included for documenting dynamical models used for simulation of ground vehicle systems. It describes the information that should be compiled to describe a model for the following user applications or use cases: (1) exchange, promotion, and selection; (2) creation requests; (3) development process management; (4) compatibility evaluation, (5) testing-in-the-loop simulations with hardware and/or software; (6) simulation applications; and (7) development and maintenance. For each use case, a Model Description Documentation (MDD) template is provided in the appendices to facilitate model documentation. In addition, an example of a completed model documentation template is provided in the appendices. Increased use of dynamical modeling and simulation for engineering development and testing of the functional performance of ground vehicles has resulted in a need for standardizing documentation of the dynamical models used. Multi-disciplinary global engineering teams spanning domains within organizations and collaborations between commercial businesses (OEMs and suppliers), government agencies, and research institutions often need to support usage of simulation models of entire ground vehicle systems and/or related subsystems. This requires a minimum level of model documentation to efficiently facilitate, integrate, and manage modeling and simulation work activities. Specifically, model documentation is essential to permit exchange and development of models as well as application and management of modeling and simulation processes. The recommended practice for model description documentation presented in this technical report will help to: (1) create a common language, (2) increase productivity of processes, (3) promote uniform testing, and (4) reduce costs.
