An important problem in reliability theory is to determine the reliability of a complex system give the reliabilities of its components. In real life, the system and its components can be found in a range of states varying from perfect functioning through various levels of performance degradation to complete failure. The focus of this research is to develop properties of system structure function and to develop computational methods for estimating system reliability measures. Multi-level modular decomposition methods are also being developed for such systems. A product must be designed for manufacturability and must be insensitive to variability present in the production environment and in the field when used by the customer.
Simultaneous engineering focuses on the integration of engineering design and manufacturing.
The purpose of this research is to develop customer-focussed reliability models which capture the total experience by the customer with the product. .
