Design for Reliability in Complex Mechatronic Systems: Concepts, Methods and Tools

A complex mechatronic system must be able to perform its specified functions in a wide spectrum of environments during its operation, storage and transportation. Thus the reliability requirements and expectations must be addressed right from the design process and sustained during the product development cycle. Further, full system level testing of complex electromechanical systems such as single shot missiles or torpedoes is often infeasible, time-consuming or very costly and thus the organization may resort to a subsystem level test methodology, which is less expensive than full system tests. The system reliability is then estimated from the system-subsystem modeling. This presentation attempts to cover the concepts, methods and tools that aid in achievement of reliability in a system and process design, i.e. Design for Reliability. Thus the achievement of desirable standards of reliability can be obtained by careful analysis in the system design phase, i.e. Reliability is built in through quality of design.
