Dr Simone Bortolami, Draper Laboratory
Complex one-of-a-kind systems are usually built to stringent performance and/or reliability requirements. Nevertheless, they remain vulnerable to catastrophic events that are often a combination of individually nonfatal events and/or processes. Also, the reliability of such systems does not commonly involve catastrophe, but rather an unexpected degradation of performance affecting the cost of maintenance and/or ownership. Thus, reliability does not necessarily mean loss of the use of a system, but also a costly decay of performance below a set threshold. For many years to date, Physics of Failure (PoF) has been the practice in several fields of engineering primarily involved with their design for life expectancy, e.g., fracture mechanics, fatigue, corrosion, etc. More recently, new simulation-based approaches have been used to address mission reliability by evaluating the impact of single failures to the key outputs of the system during its operation.
RAPSODE is a proposed approach that uses behavioral models of the system’s dynamics and embedded PoF models to evaluate the outcome of all combinations of failure and/or degradation sources, which are different for different environments and mission goals. RAPSODE uses causal networks to identify all possible failure/degradation states. At the design stage, RAPSODE can help isolate, among all critical paths, the ones with the highest influence on mission reliability, thereby driving targeted laboratory tests and fault-tolerant design. RAPSODE can also help analyze complex systems with a human-in-the-loop. Attendees will find this presentation useful in understanding the novel methodology adopted by RAPSODE in delivering powerful DfR solutions for complex systems.
Simone Bortolami, Ph.D. has extensive experience in research and development with focus on disruptive solutions. Throughout his career, he has generated and executed projects for a variety of industry and government applications. Presently, he is a lead scientist at Draper in Cambridge, MA, focusing on instrumentation and algorithms for inertial navigation, guidance, and control. From 2009 to 2012, he was director and head of three rotorcraft research centers for AgustaWestland, a multinational conglomerate with 13K+ employees and the third largest helicopter manufacturer in the world. From 2005 to 2009, he was a principal at Draper, focused on dynamics and control of spacecraft, reliability, and gravity gradiometry. From 1997 to 2005, he was senior scientist on the faculty of Brandeis University, Waltham, MA, focused on computational human neurophysiology and human space orientation. From 1994 to 1997, he was a fellow at the Harvard Medical School and an adjunct assistant professor at the Massachusetts General Hospital focused on neurophysiology and biomechanics. From 1992 to 1994, he carried out his Ph.D. research at the Radio and Geo-astronomy division of the Harvard-Smithsonian Center for Astrophysics, Cambridge, MA in and Spacecraft Dynamics and Control. Dr. Bortolami also holds a Master of Science in Mechanical Engineering from the University of Padua, Italy, 1990, and he is a certified PE in Mechanical, Industrial, and Environmental Engineering. He is the author of 40+ international publications on both human neurophysiology and spacecraft dynamics and control, which have been referenced 300+ times internationally. He has been a reviewer for several international journals in human physiology as well as subject matter expert for government agencies in aerospace engineering.
This meeting will be held on Wednesday, March 9, 2016 at MIT Lincoln Laboratory, Lexington, MA (Forbes Road location). It will begin with personal networking at 5:30 PM. The presentation will follow at 6:00 PM. Refreshments, compliments of the Reliability Chapter, will be available. You do not need to belong to IEEE to attend this event; however we welcome your consideration of IEEE memberships as career enhancing technical affiliations. We request that you register to attend by Friday, March 4, so we can plan the refreshments.
