The planning of nautical tourism development and especially, the planning of its supporting infrastructure development, is important topic of the maritime spatial planning. The focus of research is the integration of multicriteria analysis and stakeholders within concept modeling that will provide support to the spatial planning specialists in the design of plans related to the development of anchorage capacities for small vessels. It examines economic, environmental, ecological, social, and civil engineering concerns related to the use of coastal water. It is a complex and ill-defined civil engineering problem because of multiple stakeholders with diverse interests, numerous conflicting goals and criteria, huge quantities of information and data, limited resources, etc. The research is concentrated on an integral approach to sustainable decision-making within maritime spatial planning by the modeling decision support concept to the processes of identification, validation, comparison, and the selection of locations for anchorage construction, based on multicriteria methods, goal analysis, and the logic of the decision support system. The concept is tested on the island of Šolta, Croatia, and has been proven as being an applicable, consistent, efficient, and effective methodology for the planning of the anchorage locations.
In environmental projects, decision-making can be a complex and challenging task due to the in-built existence of compromises between environmental, socio-political, and economic factors. This paper explores a systematic approach to developing a decision support concept that includes the analysis of wastewater treatment problems, knowledge acquisition, and the identification and evaluation of criteria that bring forth an optimal solution to the location selection of wastewater treatment plants (WWTPs). The objective of this research is to develop a decision support concept (DSC) to aid in the planning phases of complex engineering projects, such as the construction of WWTP. The development of the concept starts with an assessment of the issue and an identification of relevant stakeholders accepting their different views and attitudes in an attempt to resolve this issue. The DSC was tested on a real case project—WWTP location selection within the town of Kutina, Croatia. Results indicate that it is possible to develop such a concept based on multicriteria methods on which decision-makers can rely.
Planning of sustainable urban renewal is one of the key issues for city development. Particular emphasis is placed on the problem of the sustainable urban renewal of areas that are made up of a large number of private cadastral parcels that cause ownership fragmentation. Urban renewal is most often carried out to realize a large project where it is necessary to determine the optimal way of its realization. This paper proposes a methodology for assessing the index of fragmentation for the purpose of sustainable urban renewal planning. The methods used to solve the task are Simple Additive Weighting method (SAW) for ranking alternative solutions (i.e., cadastral parcels, spatial elements and areas of future construction), and the Fuzzy Analytic Hierarchy Process method (FAHP) for defining the criteria weights. In the process of defining the index of fragmentation model as well as the weighting determination, a group of experts was involved. The proposed model was tested on the field of the construction of the University of Split campus, for which implementation was planned in several periods. The obtained results show that the proposed methodology can provide support in analyzing the spatial–functional capacities of the existing land, and for decision making in optimizing the realization of urban projects.
Land fragmentation is one of the main obstacles to sustainable agricultural and rural development. The main goal of sustainable agriculture development is the production of food by the synergy of economic, social and ecological requirements. The ineffective and defective legislation and even its complete absence have led to land degradation globally. The most adaptable and globally recognized method that has the effect to solve the existing land fragmentation and to prevent the trend of even more intensive land fragmentation is the method of land consolidation. Land consolidation is carried out in a way that each participant in the process of land consolidation gets new land of equal value, with land value reduction for general and common needs of settlements and participants of consolidation. The value of the land included in consolidation process is determined and shown in land consolidation assessment which is conducted by land classification in the defined classes, and the value in the land consolidation evaluation is shown in the estimation units. The estimation unit is the relative relation between the exemplar cadastral parcel and the cadastral parcel which need to be valued, taking into account all the relevant factors that can affect the land valuation. This paper proposes a model of land classification in the evaluation classes based on the Fuzzy Logic Method. The paper aims to develop an expert system that would improve and optimize the process of relative valuation of agricultural land as one of the critical steps in the implementation of the land consolidation. The proposed expert system would provide effective support in conducting the negotiation procedures and planning of land consolidation implementation with the involvement of different stakeholder groups with different requirements and wishes. The model will be validated for agricultural land on the island of Hvar in the Split-Dalmatia County.
