Abstract: Model‐based systems engineering (MBSE) approaches are based on a paradigm shift from document‐centric engineering to model‐based engineering. Although MBSE methods are intended to apply across the entire system life cycle, one area that has not received much attention to date is the role of test and evaluation. Test and evaluation activities provide information that reduces the uncertainty about system performance, effectiveness, and suitability. This uncertainty reduction becomes particularly important within the context of defense systems, which can cost billions of dollars. This paper describes a methodology that uses an MBSE framework and Monte Carlo simulation to define uncertainty reduction goals for test planners to use in developing test strategies and detailed test designs for evaluating technical performance parameters. As tests are completed, physical models can be updated with test data and additional analyses conducted with combat models to determine if the system meets user requirements. The methodology is demonstrated through a simple case study involving a series of tests to predict the landing performance of an aircraft. ©2012 Wiley Periodicals, Inc. Syst Eng 16:
