ABSTRACT
In this chapter, we continue our evaluation of the development of methods for tackling large-scale systems (LSS). In particular, the models of LSS summarized in the sequel are distinguished by the degree to which they reflect the internal structure of the overall system. Then we focus on the concept of system decomposition and disclose the effective tool of overlapping decomposition. The process of actual tearing of the system may be performed from either conceptual or numerical reasons. Conceptual reasons correspond usually with the boundaries of physical subsystems. Numerical reasons require to develop a universal decomposition technique.
