Multimethod approach to modelling of complex sociotechnical systems

Abstract

Systems Engineering has to solve increasingly complex problems through the implementation of solution systems. Solving contemporary complex problems requires Systems Thinking to address the emergent and evolutionary behavior. System Dynamics, Cognitive Work Analysis and Systems Engineering all have their roots in the systems approach and Systems Thinking, albeit with a different focus. Integrating System Dynamics and Cognitive Work Analysis through Model Based Systems Engineering process provides an approach to model complex sociotechnical systems. This paper describes and demonstrates an integrated multimethod modelling approach with these methodologies. The modelling approach should assist in addressing Systems Engineering’s three evils; complexity, understanding and communication.
