Physics-Based Model | A mathematical representation of the physical laws governing the behavior of the system of interest. | NAFEMS-INCOSE SMSWG T&D Focus Team |
Physical Model IPM (Ideal Physical model) | A collection of tangible components, whose physical attributes mirror those of the system being modeled. | NAFEMS-INCOSE SMSWG T&D Focus Team |
| Process | Set of interrelated or interacting activities which transforms inputs into outputs. | ISO 9000 |
| Process Model | Model that defines the functional decomposition and the flow of inputs and outputs for a system. | Modeling & Simulation Coordination Office |
Processor in the Loop (PIL) | A simulation approach that allows designers to evaluate production code running on a dedicated processor in conjunction with a simulated plant. | NAFEMS-INCOSE SMSWG T&D Focus Team |
