The overall objective of the DSoS project is to develop significantly
improved means for composing a dependable system of systems (SoS) from a
set of largely autonomous component computer systems. The focus of the
project will be on the design, placement and properties of the linking
interfaces (LIFs) that form the common boundaries between component
systems. More specifically, the project will : identify the properties
of LIFs that are needed to achieve the planned objectives of an Sos;
develop methods for reasoning about the management of an SoS composed of
systems from different domains of management; explore the use of
LIF-based fault tolerance mechanisms to enhance the dependability of
SoSs; develop validation techniques for ensuring that the specified
dependability requirements of an Sos are achieved; evaluate the
strengths and weaknesses of the LIF-based approach using a series of
case studies based on current industrial practice.
