Introduction -- Reflections and theoretical contributions regarding trainers’ practices and simulation -- Airliners Flying -- Piloting nuclear reactors -- The simulator of critical situations in Anesthesia -- Surgical virtual simulation: the first steps of a new training -- Simulation to train hot rolling mill operators in metalwork.Drawing on decades of industrial experience, this insightful and practical guide uses case studies and an interdisciplinary perspective to explain the fundamentals of simulation training to improve performance of high-risk professional activities. It seeks to identify those conditions under which simulation training has been shown to improve professional practice while employing extensive real examples. Simulation Training: Fundamentals and Application helps readers to develop their own synthesis of the simulation learning method and to use such training to enhance their skills and performance. Case studies demonstrate five specific theatres of professional practice - the nuclear-power industry, aeronautics, surgery, anesthesia, and metallurgy – and then detailed analysis highlights the common factors and key results. The authors' background as  Human Factors Consultant, Physicist, Psychologist, and Occupational Didactics expert has enriched studies of humans in work situations, work organization and management. Authors have also been involved in pedagogical conception of experimental training on simulators based on their professional experience. The book is useful to practitioners, researchers and students, both in industry and in university. It is clearly cross disciplinary as it presents and discusses applications in engineering, professional practice (airline pilots) and medicine.
