1.3 Intended application

The proposed integrated management solution of smart sustainable cities aims at tackling four main
types of problems, namely inadequate safety and security protection, increasingly worsened urban
environment, damaged city infrastructure, and natural or man‐made emergency events. In this
Technical Report, these four types of problems are represented as theoretical events through a
uniform event information model. They are detected by sensors, recorded by observations,
analysed and processed by models, and finally settled by a decision made according to nodes. The
goal of IMSSC is achieved by the direct management of information resource carriers, events,
sensors, observations, models, and nodes. The roles of the different information resources in IMSSC
are presented in Figure 3:

These information resources represent the crucial infrastructure for real‐time monitoring of city
dynamic processes. However, these resources have not yet been efficiently used due to the lack of
a unified management of the observation resources and information carriers, the rapid and smooth
processing of information, as well as the real‐time publishing and sharing services. As a consequence,
the interconnection among the different city departments has not been established yet. This is a
missed opportunity for every city administration as events like traffic congestion, urban flooding,
and pipeline leakage that existed before perpetuate. The operational efficiency of cities is not
always as satisfying as it could be, affecting negatively citizens' quality of life. Therefore, it is
imperative to perform IMSSC to resolve all the challenges described above.
