In this podcast from the Carnegie Mellon University Software Engineering Institute, Douglass Post and Richard Kendall, authors of "Creating and Using Virtual Prototyping Software: Principles and Practices" discuss with principal researcher Suzanne Miller experiences and insights that they gleaned from applying virtual prototyping in CREATE (Computational Research and Engineering Acquisition Tools and Environments), a multiyear DoD program to develop and deploy software for systems like ships, air vehicles, ground vehicles, and radio-frequency antennas. CREATE enabled engineers and scientists to design these complex systems and to accurately predict their performance.
