The solutions to the power projection, transportation, and operational needs of the Navy as it faces the 21st century must account for reduced manning levels. This leads natu- rally to increased use of computers, automation, and intelligent systems in the concept and design of the next genera- tion of ships. In addition to the acknowledgedhardware needs, the prob- lem of autonomic and autonomous control of shipboard systems and missions are amenable to and will, in fact, require software solutions. Despite current tech- nolom, large, reliable software systems are difficult to achieve because correct- ness in requirements analysis, design, implementation, testing, modification, and maintenance of software are difficult. Software is also difficult to quantize and display; hence, the effort and costs involved in its development are easily underestimated. This paper describes an approach to the problem of providing structure, in the form of a software architecture, to the software performing autonomous control of missions and their related tasks. In concert with the need to reduce complexity, the architecture must support simple, rapid reconfigura- tion of code should vehicle capabilitiesor mission requirements change. Building upon recent efforts with control of Autonomous Underwater Vehicles (AUVs), we propose a tri-level control system architecture called the Rational Behavior Model (RBM) as an approach to autonomous and autonomic control of surface ship missions and systems.
