The phenomenon known as urban heat islands (UHIs) is becoming more common and widespread, especially in large cities and metropolises around the world. The main cause of these temperature variations between the city center and the suburbs is the replacement of large tracts of natural land with artificial (built-up) surfaces that absorb solar heat and radiate it back at night. UHIs have been the subject of numerous studies, most of which were about defining the main characteristics, factors, indexes, etc., of UHIs using remote sensing technologies or about determining mitigating activities. This paper provides a comprehensive overview of the literature, as well as a bibliometric analysis, to discover research trends related to the application of decision support systems and multi-criteria decision-making for UHI management, with a special emphasis on fuzzy theory. Data collection is conducted using the Scopus bibliographic database. Throughout the literature review, it was found that there were not many studies on multi-criteria analysis and decision support system applications regarding UHIs. The fuzzy theory application was also reviewed, resulting in only a few references. However, this topic is current, with an increase in published papers, and authors see this as an opportunity for improvement and further research. [ABSTRACT FROM AUTHOR]

The paper proposes a Model of priority ranking of cadastral parcels for planning the implementation of urban consolidation, which is a continuation of the published research on the assessment of fragmentation and assessment bonitet values of cadastral parcels. The research deals with one segment of the Spatial Decision Support System and is one process in the planning of urban consolidation. Comparison criteria were identified for the evaluation and priority ranking of cadastral parcels. The subject of the research is private cadastral parcels in the area of large public project construction. The goal of the research is to find the optimal way to compare conflicting and incomparable criteria for the evaluation of private cadastral parcels and, at the same time, a way of fitting the opinions of stakeholders in the implementation planning process of urban consolidation. Due to the complexity of the task and realizing certain spatial criteria, unique models were developed. Special attention was paid to the participatory approach to problem-solving, in which all groups of stakeholders were identified, and the way of expressing their views was defined. The Complex proportional assessment (COPRAS) method and the Analytic Hierarchy Process method (AHP) methods were used to solve the problem. The defined models were tested in the field of construction of a large public project Campus at the University of Split. [ABSTRACT FROM AUTHOR]
