Dependability as a criterion for distributed systems design

摘要

This paper deals with an approach developed within our laboratory whih aims to help to design intelligent or integrated systems. Its objective are the choice of the best material architecture and task sallocation. These systems are composed of communication networks and intelligent instruments. This approach is based on a functional modelling which provides a set of tasks. From this set, several allocations are considered. Thanks to the evaluation of criteria of cost, availability and reliability, the best architecture is determined. The originality of the paper deals mainly with the use of dependability as a criterion durin the design phase of distributed systems.
