Contribution à l'évaluation quantitative de la sureté de fonctionnement des systèmes d'automatisation en phase de conception

Abstract : This work concerns the evaluation of dependability used as an explicit criterion for the design of automation systems. This document is organised in the following way: A first part defines the concepts of automation systems and distributed intelligence base automation systems, and then Lays down the general problem about their design. Dependability and the main notions about dependability are introduced. A second part presents several representations which may be used when designing a system. A third part deals with the usuai methods used to quantify the different aspects of dependability. Among them, the methods which deal with availability and reliability/security are more developed. Finally, the binary decision diagrams are tackled as a tool to evaluate these aspects of dependability. A fourth part presents the proposed method for the design of automation systems. It uses a combinatory research in order ta optimise the designed architecture thanks to criteria about dependability. A last part iIlustrates the proposed method on two examples.
