Description / Abstract:
Scope of This Book
As stated earlier, this book will cover most of the areas shown
in Figure 1.1, with the exception of cost, which was covered
briefly in the last section. With such a new subject, the book aims
to bring Systems Engineering and Quality Management procedures to
bear on NFF and illustrate their use with a number of use
cases.
With the plethora of definitions and terminology used in the NFF
area, chapter 2 deals with terminology, and aims to give a
consistent set of definitions for the book, something that will
hopefully be embraced by the community. This is followed by chapter
3 on the importance of the human in the loop. Sometimes engineers
or technologists forget that a piece of equipment or a technology
is not, in itself, the solution to a problem. It is only when the
humans that operate the system buy in, and totally understand and
accept new methods, that success is achieved.
Next, the book tackles NFF and systems effectiveness, looking at
its component parts of availability and safety in chapters 4 and 5,
respectively. The ideas expressed in chapter 5 are, perhaps, the
most speculative in the book but aim to give current thinking in
regard to NFF and safety.
The book then moves on to aspects of management. Operating
policies are discussed in chapter 6 before chapter 7 proposes a
benchmarking tool for NFF. The use of this tool will allow
organizations to see at what level they are addressing the NFF
problem and what is involved in moving to the next level.
The complexity brought about by modern embedded electronics
poses unprecedented challenges in maintenance and repair,
threatening customer satisfaction and causing increased warranty
costs. This, of course, has an impact on the testability of an item
and may result in the incorrect fault detection and hence
contribute to the NFF phenomenon. In light of this, a look at
system and diagnostic design is taken in chapter 8; with the right
technology, to increase diagnosis, being examined in chapter 9.
The book concludes with chapter 10, which gives an overall
summary and thoughts on future direction.
