Sustainable development is a process of development that "satisfies the needs of the present without diminishing the ability of future generations to meet their own needs". The content of the dissertation is to circumscribe the above-described idea through the state of two European capitals through its approaches.
The conceptual description contributes for its understanding and justification through its specific areas, reaching out to cities, which I will outline in more detail. A more detailed description of it, to illustrate its importance and actuality, is presented as a separate paragraph, reaching the concept of the Smart City initiative.
The interpretation of Smart City and a sustainable city encounters limits, there is no exact definition. In the absence of this, Smart City as a whole, then its sub-dimensions are defined, explained and discussed in detail. Hereinafter, I compare the conceptual anomalies of sustainable city and Smart City, highlighting their differences and the existing parallels between them.
After the expansion of the concept, I pay attention to the "Smart" factors of the city, and then I present existing practical examples to illustrate the possibilities of its implementation through the cities examined.
The "Degree of Smartness" is used to illustrate the development of the aforementioned cities, which is based on a software based on fuzzy logic. Before concretizing the calculation, the mathematical principles of the method are presented. Next, I briefly describe the software used and then the results obtained.
From the outputs, the cities are compared, highlighting the backward, critical areas that I seek for practical solutions to catch up with. Finally, the dissertation ends with the final conclusion.
