Smart cities, multi-system approach to system modelling

In the following contribution an attention is devoted to the system description of the urban and economic function of settlements considered as the “Smart Cities”. There is a general approach respecting main urban properties and functions as objects of smart control of basic functions from the system theory point of view. There is an introduction to methodology of description of multi-system functions of settlements with number of quasi-independent parts, given by organization of public sectors or by geo-morphological conditions creating different production function of parts. In this description the genetic code of individual parts is respected as well as Systems Identity and the synergy in resulting production function.
