The usual aim of computer-aided design is to bridge the interface between design and production. However, an interface also exsists between design and maintenance. The author of this paper introduces some concepts, which are currently being considered, for improving design for maintainability with manual design processes and indicates their potential development for use with c-a.d, systems.
Computer-aided design in the electronics industry is evolving from a collection of discrete programs into integrated design systems which aim to bridge the interface between design and production. An interface also exists, however, between design and maintenance.. This has always been a difficult and neglected area because the designer works on the same firm as the producer, whereas the maintainer is often part of the customer's organisation. If computer-aided design can help to bridge this gap between designer and maintainer, great improvements in maintainability of the resulting equipment could be possible. This paper introduces some concepts which are under consideration for improving design for maintainability for use with manual design processes and indicates their potential development for use with computer-aided design systems.
There are two main approaches to better maintainability. These are: a. to improve manual testing and fault finding, b. to exploit automatic testing and fault finding. The manual fault-finding approach further sub-divides into:
a. improved documentation in service, b. improved equipment design by better documentation development. Each of these approaches depends on the others. Each will be briefly described in relation to manual design before considering their extension into computer-aided design.
