Вот тут http://mbse.gfse.de/ ребята из немецкого отделения INCOSE дают определение model для model-based systems engineering: A model is an approximation, representation, or idealization of selected aspects of the structure, behavior, operation, or other characteristics of a real-world process, concept, or system (IEEE 610.12-1990), i.e. an abstraction. A model usually offers different views in order to serve different purposes. A view is a representation of a system from the perspective of related concerns or issues (IEEE 1471-2000).
