The Joint Modeling and Simulation System a Common Modeling Architecture for the Dod

The Joint Modeling and Simulation System (J-MASS) is developing an architecture which will enhance the modeling and simulation (M&S) capability of the Department of Defense (DoD) community. The development standards and software tools implemented by J-MASS supports a disciplined approach to the development, configuration, operation, and analysis of digital models and simulations. J-MASS is an object-based modeling system designed to enhance supportability and maintainability. J-MASS will provide a library of verified and validated software components and models of weapon systems developed by the RDT&E community, models of threat systems developed by the intelligence community, and models of environmental effects provided by the scientific community. Because the models developed under J-MASS will have software components that are designed to consistent standards, the components can be reused to rapidly build other models and simulations. This ability to readily access and reuse existing models and components will result in large savings to the DoD in an era of shrinking budgets. J-MASS will truly provide the DoD with a common modeling architecture.
