Systems Science is the study of general principles governing systems of widely differing types, and the use of systems ideas and methods in interdisciplinary research and socio-technical system design and management. Systems science draws on the natural and social sciences, mathematics, computer science, and engineering to address complex problems in the public and private sectors.
