RCS applications and its computing principles cover a wide range of systems and techniques. The expert system directs applications in intelligent command or control systems. Such applications include process control, pervasive computing, as well as vision, robotics, and embedded systems. Although RCS has emerged from variant versions over the years, it presently has the immense capability to comprehend the sophisticated and complex Intelligent System Design. Developed by NIST, the software system is engineered for reference model architecture, as opposed to any form of system design specification.
