Contemporary approaches to control system specification and design applied to KAON

Large data acquisition and control systems have evolved from early centralized computer systems to become multi-processor, distributed systems. While the complexity of these systems has increased our ability to reliably manage their construction has not kept pace. Structured analysis and real-time structured analysis have been used successfully to specify systems but, from a project management viewpoint, both lead to different classes of problems during implementation and maintenance. The KAON Factory central control system study employed a uniform approach to requirements analysis and architectural design. The methodology was based on well established object-oriented principles and was free of the problems inherent in the older methodologies. The methodology is presently being used to implement two systems at TRIUMF. (Author) 12 refs
