Design for Reliability (DFR) has become a worldwide goal regardless of the industry. The engineering managers are intent on harvesting the value proposition for competing globally while significantly lowering the life cycle costs. The DFR principles ... are based on proactively preventing hardware failures, software failures, and product malfunctions. Most experienced engineers are expert in a segment of the field, and need to understand the entire field. This is obvious from the NASA Challenger accident, and millions of automobiles recalled by Toyota, GM, and Volkswagen. This science of engineering requires creativity and innovative skills to aim at zero failures and elegant solutions that cost less, which is the aim of this course.

(ENME737) An enabling discipline consisting of technologies and methods to assess the reliability of a product in its actual life cycle conditions to determine the advent of failure and mitigate system risk. PHM permits the reliability of a ... system to be evaluated and predicted in its actual application conditions. In recent years, prognostics and health management (PHM) has emerged as a key enabling technology to provide an early warning of failure; to forecast maintenance as needed; to reduce maintenance cycles; to assess the potential for life extensions; and to improve future designs and qualification methods. In future, PHM will enable systems to assess their own real-time performance (self-cognizant health management and diagnostics) under actual usage conditions and adaptively enhance life cycle sustainment with risk-mitigation actions that will virtually eliminate unplanned failures.

General Mechanical
In the course of engineering design, project management, and other functions, engineers have to make decisions, almost always under time and budget constraints. Managing risk requires making decisions in the presence of uncertainty. This course ... will cover material on individual decision making, group decision making, and organizations of decision-makers. The course will present techniques for making better decisions, for understanding how decisions are related to each other, and for managing risk.
