Large scale Socio-Technical Systems (LSTSs) operating over networks (such as the electricity system , the railways , the airspace system , Internet…) have radically changed our daily lives over the past few decades and also transformed the way our Societies work . They represent a phenomenon that is conducive to enthusiasm , which contributes to the democratization process of societies everywhere, offering new features and services over the coming years , consequences and sources of new techniques and technologies : in this light , LSTSs appeared as a natural field for investigation by our Academy .
They have undergone considerable development already (and continue to do so) not only in terms of technological progress in their on area (photovoltaic arrays to produce electricity commercially , high speed trains (TGVs in France) for rail transport , mobile phones for inter-personal communications…) but also thanks to new ICTs , themselves being sources of change in the way they work and the scope of services they offer.
