The engineering of large, complex systems is a difficult task. In the increasingly competitive arena of defense contracting, there is a need for easy‐to‐use tools to analyze tasks quickly. A multi‐year project at Boeing uses hierarchical model‐based reasoning and distributed systems to develop tools for early analysis of complex systems. These tools assist the earliest efforts of systems engineers to test alternative concepts, to derive system requirements, to identify potential problems, and to explore key system design issues. The Process Flow modeling tool (pFlow) is a hierarchical, graphics‐based modeling and simulation tool. A Systems Prototyping Environment (SysPro) provides virtual communications, a thread‐based computing paradigm for the UNIX TM operating system, and computer language wrappers to assist engineers in evolving new systems. Moreover, it provides a formalized specification and migration path toward a final system design.
