| Popis: | International audience; Object-Oriented Technologies, such as Java, provide efficient features to develop software applications. In particular, they allow the development costs to be reduced. However, issues highlighted by the “Object- Oriented Technology in Aviation” group have to be handled to guarantee a high level of safety, in order to use such technologies in avionics software. In particular, the risk of Object-Oriented Technologies design faults has to be reduced to an acceptable level. These risk reduction actions must be preceded by forecasting the actual risk level of the developed application. The paper aims at presenting a method used to forecast the risk of the presence of these Object-Oriented Technologies faults in a given program. The approach proposed is based on Bayesian networks. Its principles are introduced. It is illustrated on an example of faults: the Accidental Overriding (AO). We highlight that our approach takes into account the complex relationships existing between the various object-oriented features: inheritance, distribution of the attributes and methods, etc. To conclude, we show how the obtained data can be analysed to specify design guidelines allowing an acceptable risk level to be reached. |
