PSE prospective: Paradigm transition towards Complex Thought in a global world under pressure
Résumé
Many people confront and acknowledge irreversible anthropogenic changes as many global world limits are exceeded. As contributors, process system engineering research activities must undergo a transition within a novel paradigm more fit for addressing the general complexity of all impacted systems. This paper explores three shifts, covering methodological, epistemological and metaphysical intertwined aspects. About methodologies, we discuss energy savings, process intensification and sustainable growth issues, and suggest simultaneously keeping systemic and multiscale approaches and dropping Cartesian reductionism for producing knowledge and engineering expertise that will enable attenuation and adaptation solutions to better address the current challenges. But for that, underlying epistemological and metaphysical aspects must also be revisited. A participative PSE process is proposed to investigate systems in transition, in the spirit of the complex thought paradigm and constructivism, and to head towards not only sustainable but also desirable solutions for people.
