We develop aircraft design concepts using the latest in probabilistic concepts for acceptance criteria. We help airframe designers evolve from margin-of-safety oriented designs, to designs for an optimum of probability of failure. For the past decade, we have pioneered the integration of state-of-the-art reliability methods and failure models to develop better ways to design, manufacture, and maintain engineering systems. We develop reliability technology to quantify reliability and safety, identify key variables, and integrate cost and risk assessments into engineering decisions.
