Alain Leroy started his career in offshore engineering and was for ten years with the insurance industry. However, he has worked for most of his career in reliability engineering, focusing mainly on the implementation and use of novel approaches and techniques for assessing dependability parameters in the oil and gas industry. He has delivered courses on reliability at both basic and high levels.Jean-Pierre Signoret has been in charge of the research and development of methods and tools in reliability engineering, as well as of practical studies related to reliability modelling. He is still involved in the development of several international standards, including IEC and ISO, related to dependability, functional safety, reliability data collection, and production assurance. As a member of TPA, he gives short courses in various universities on this topic.
