Flexibility: a multi-disciplinary literature review and a research agenda for designing flexible engineering systems

JH Saleh, G Mark, NC Jordan - Journal of engineering design, 2009 - Taylor & Francis
Flexibility, despite its popularity, is not yet an academically mature concept–compared with
optimality and robustness, for example. Flexibility is nevertheless recognised as a critical …
