Complexity Reduction, a Pragmatic, Semantic Approach


An increasing need for shared communication in disparate domains as well as the production of increasingly dynamic, large-scale systems has always been at the heart of the practice of systems engineering.

As a branch of general systems theory, systems engineering was developed to address practical considerations posed by diverse organizations, environments and cultures within which systems are designed, developed and operated. System design and evaluation standards, prototypes, languages and semantics are discussed in the context of pragmatic system complexity reduction.

Types and categories of complexity are used in this discussion to focus on complexity and the reduction of complexity. Formal and theoretical foundations of systems science and systems engineering provide the basis upon which many effective systems engineering tools were built. Some of the classical tools of systems science and systems engineering that manage complexity are described. Based on these classical tool components and principles, abstract relation types (ART) were developed to enhance the understanding and application of these tools.

A pragmatic approach is presented that is designed to reduce complexity, as well as compare relative complexity reduction between and among methods. The direct value of systems engineering techniques as they are applied in any context, is rooted in the ability of systems engineering techniques and practitioners to reduce the cognitive complexity associated with the systems' problem of interest.

    Great! Very concise presentation on complexity issues within the realms of cognicent and computational capabilities, interfacing between systems, and new ideas for addressing highly complex systems by using both resources correctly and efficiently. The challenge has been put forward to consider benefits to and from the Semantic community in using these techniques. Really enjoyed the presentation!
