This book presents the proceedings of the Eighth National Conference of the Italian Systems Society. The contributions underline the need for Systemics and Systems Science in order to address multiple, changing systems involving several coherent versions. The conference focused on identifying,...

Information and communication technologies (ICT), which are transforming most areas, develop non-linearly. Failure to take into account the nonlinear principles of complex dynamic systems hinders the development of balanced innovation strategies. Companies and governments lose the ability to...

We present an analytical solution for the connectivity of a network model with a "non-simultaneous" linking scheme. Despite its simplicity, this model exhibits node-space correlations in the link distribution, and anomalous fluctuations behavior of the time series of the connectivity variable,...

Since Lėon Walras neoclassical economists hold an inalterable belief in a unique and stable equilibrium for the economic system which however remains to this day unobservable. Yet that belief is the corner stone of other theories such as the "Efficient Market Hypothesis" as well as the...

This paper questions the dynamic stability of supplier-buyer networks. We investigate a simple rewiring process, by which firms change suppliers if it increases profit, within an otherwise classical production network model with market clearing, profit-maximization, and complete information. We...
