<p>According to population growth and consequently students growth and on the other hand lack of educational spaces, imbalance in supply (students) and demand (educational centers), it causes high population density of students in classrooms, beyond standards. In addition, imbalanced population density causes accessibility problems to these centers and also spending a lot of students’ time and money. The mentioned problems are due to weaknesses in the construction of schools in appropriate locations. Lots of urban dilemmas such as traffic, pollution, Social and cultural issues and security can reduce by choosing appropriate location for construction of schools. There are different methods for determining the appropriate locations for the construction of schools, among which the most important is the hierarchical process analysis method. In this study, using Fuzzy logic in the geographical information system (GIS), space Distribution and Location of deployment and Functional radius of the elementary schools in the Qazvin city have investigated  and also in the network analysis method, areas out of schools coverage have been specified. Then, using Fuzzy Analytical Hierarchy Process, layers, criteria and also effective sub-criteria in choosing location of elementary schools, weighted and combined each other and appropriate and inappropriate locations for construction of elementary schools, especially in areas that placed out of schools coverage, have obtained. Results show that the elementary schools of the Qazvin city aren’t enough for covering all of the total area, and some of the northern, eastern and western neighborhoods despite having the necessary student density, are deprived of having elementary school and also are out of the coverage of existing schools.</p>

Hierarchy Process

Analytic hierarchy process (AHP) is one of effective decision making methods used in order to take a complex issue. Through AHP, an uncstructured complex issue can be simplified into a structured parts in a hierarchy. AHP method is used to determine the priority of problems that have a multi criteria quality. In this final thesis, the researcher will discuss about the acceptance of research title in nursery faculty in Andalas University as Prodi’s secretary consideration material which is submitted by the student. In all three selected alternatives, they must meet the requirement of these five criterias which consist of phenomenon, research object, research method, purpose and significance of the research, and finally reference. The result of this research is a qualified research based on previous criterias which is enlisted from priority through analytical hierarchy process analysis method. Thus, this decision support system is expected to be able to help Prodi’s secretary to easily determine alternative of the best title which will be submitted by the students to meet the expected qualification set by the university

Hierarchy Process

Decisions usually involve the getting the best solution, selecting the suitable experiments, most appropriate judgments, taking the quality results etc., using some techniques.  Every decision making can be considered as the choice from the set of alternatives based on a set of criteria.  The fuzzy analytic hierarchy process is a multi-criteria decision making and is dealing with decision making problems through pairwise comparisons mode [10].  The weight vectors from this comparison model are obtained by using extent analysis method.  This paper concern with an alternate method of finding the weight vectors from the original fuzzy AHP decision model (moderate fuzzy AHP model), that has the same rank as obtained in original fuzzy AHP and ideal fuzzy AHP decision models.

From January 2020, the International Maritime Organization has regulated ship emissions to reduce sulfur content. As an alternative to this, LNG bunkering was proposed, and infrastructure and ships were deployed. Therefore, we used analytic hierarchy process AHP techniques to determine optimal methods of LNG bunkering for shipyard safety. First, we conducted a literature survey on the concept and type of LNG bunkering, global LNG bunkering trends, and features of Japan and South Korea cases and compared them. Thereafter, an expert survey was conducted, and survey data was analyzed using AHP techniques. Finally, we derived optimal methods applicable to shipyard industry. The analytical results revealed that the derived priority of the optimal LNG bunkering method of shipyard was in the order of the STS method, TTS method, and the PTS method. The result of this study can serve as a theoretical basis to make LNG bunkering safer and more economical in shipyards to prepare for the expansion of demand of LNG-fueled ships and LNG. However, this study inevitably has limitations of ranking reversals paradox as it was conducted by experts, assuming no weights to STS, TTS, or PTS.

The application of analytical hierarchy process (AHP) to the risk analysis of port construction project was investigated. Firstly, the happening probabilities of various risk factors during port construction were calculated. Secondly, the aftereffects of the risks were concluded by consulting the experts. Thirdly, the weight of each risk factor was obtained by AHP. Finally, the total risk of port construction project could be evaluated by fuzzy comprehensive evaluation. This risk analysis method was applied to evaluate the total risk of a real port construction project, and the exemplification verified its feasibility.

Recently river corridors in Guangzhou are being focused on as important natural networks in urban environment as well as cultural and recreational resources. The study area of this research is the Licheng section of the Zengjiang River Greenway. We attempt to do a comprehensive evaluation of its built environment by visitor experience. The main research contents were divided into 6 aspects: facilities, green space, signs and maps, transport, security and management, and recreational activities in external environment. Through the analysis, we identified six human dimensions of visitor experience in the studies: cleanliness, aesthetic, comfort, safety, suitability and hydrophilic property. As a result of this research, some problems on the evaluation were grasped by the hierarchy process analysis based on the above six categories. We concluded by discussing solutions of these problems, and suggested some proposals in design to meet the visitors’ requirement for the future construction of greenway. The Zengjiang River Greenway has served as a model for riparian greenways elsewhere in the Pearl River Delta.
