A Future System Design Technique Based on Functional Decomposition, Supported by Quantifiable Design Aims, and Guidelines for Minimum Maintenance Costs,
ROYAL AIRCRAFT ESTABLISHMENT FARNBOROUGH (ENGLAND)
The increasing cost and complexity of modern fast-jet aircraft, coupled with the long development period which takes place while technology is charging rapidly, make it necessary to consider a new approach to system design. Such an approach should be based on a structural top-down procedure, in which the rather general requirement can be changed into a detailed documented design in a controlled manner. One important aspect of design is cost, and in particular cost-effectiveness and life-cycle cost. At least some of the design aims can be based on cost-effectiveness reasoning, and it is necessary to have an appreciation of the background to this. Reliability-dependent maintenance costs can amount to much more than the original purchase price, and hence it is essential to be aware of the possible cost-drivers, and include maintenance aspects in the design approach from the beginning. This paper describes some of the work carried out at RAE on these aspects. Author
