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.”
