CIRCA: a cooperative intelligent real-time control architecture

Most research into applying AI techniques to real-time control problems has limited the power of AI methods or embedded reactivity in an AI system. An alternative, cooperative architecture is presented. It uses separate AI and real-time subsystems to address the problems for which each is designed. A structured interface allows the subsystems to communicate without compromising their respective performance goals. By reasoning about its own bounded reactivity, cooperative intelligent real-time control architecture (CIRCA) can guarantee that it will meet hard deadlines while still using unpredictable AI methods. With its abilities to guarantee or trade off the timeliness, precision, confidence, and completeness of its output, CIRCA provides more flexible performance than previous systems
