Modelling methodology for engineering of complex sociotechnical systems

Abstract

Different systems engineering techniques and approaches are applied to design and develop complex sociotechnical systems for complex problems. In a complex sociotechnical system cognitive and social humans use information technology to make sense of a situation in support of decisions. The complex dynamic system elements, their interaction and, the complex environment make sociotechnical systems difficult to develop. A modelling and assessment methodology in support of the Systems Engineering process is required to understand the sociotechnical system’s behaviour and underlying structure. It must capture the dynamic interaction as well as the effect of humans performing work in a complex environment. Cognitive Work Analysis and System Dynamics are two complementary approaches that can be applied in support of each other within this context.
