RELIABILITY ANALYSIS METHOD APPLIED TO AN AUTOMOTIVE SYSTEM
The electronic Engine Control System (C.E.M) developed by Alfa Romeo may be regarded as an example of a complex, highly innovative system, which requires a new approach to conventional methods used in the automotive field for reliability analysis. This paper shows the work undertaken b Alfa Romeo to define data collection procedures and formulae to elaborate the statistical parameters of reliability models, in order to gain suitable feed-back data. A particular point of procedures is that starting from the general system reliability target; this method permits assignment of special targets for each component of the system; the method has been checked by present application also in system and components other than the C.E.M. In particular, the comprehensive C.E.M. program for field reliability performances, consisting first of 10 taxi-cars, then 27 prototypes and present running 1,000-vehicle test-fleet, has been designed and used as a practical application for these procedures and study.
