A component-based framework for modeling and simulation (M&S) is proposed as a solution for handling the complex problem of analyzing the validity of a M&S enabling product. Validity refers to the degree that a model and its behavior are suitable representations of the real system and its behavior with respect to an intended purpose of model application. A set of properties related to simulation limitations and capabilities is proposed. Structured by a formal framework, those properties allows simulation user specifying their expected degree of validity to reach their intended purpose. Then compatibility rules are specified and signature matching is used to check the compatibility between the M&S enabling product and its intended purpose.
