Smart technology is a vital key to make cities more efficient in terms of resources usage, which is indispensable to support sustainability and resilience in cities. Nevertheless, limited studies suit the African situation regarding this matter. Also, there are no strategies adopted to define sectors' priorities. This strategy is vital to enable the application of smart technologies and policies of new cities in Upper Egypt. Accordingly, this paper presents a Fuzzy Assessment Model for Sectors Priorities (FAMSP) to distinguish and prioritize sectors in terms of smartness. A focus-group survey was then done to determine the Importance of the sectors (IS) and the low cost of sectors (LS). Results obtained from the survey were applied in the fuzzy model. Fuzzy sectors priorities, FSP is the output of applying the IS and the LS in the model. Finally, this study aims to test the (FSP) through Spearman's and Kendall's tests. Obtained results proved that the proposed model can be used successfully in determining and ordering sectors priorities to be transformed into smart sectors.
