“…Next, we note that the statement and algorithm suggested in the paper hold for arbitrary natural ( ≥ 2). This enables formulating and solving the relatively complex AHP problems with large number of criteria and huge number of alternatives like those in [1][2][3][4][5][6].…”

36 years ago, Thomas Saaty introduced a new mathematical methodology, called Analytic Hierarchy Process (AHP), regarding the decision-making processes. The methodology was widely applied by Saaty and by other authors in the different human activity areas, like planning, business, education, healthcare, etc. but, in general, in the area of management. In this paper, we provide two new proofs for well-known statement that the maximal eigenvalue λmax is equal to n for the eigenvector problem Aw=λw, where A is, so-called, the consistent matrix of pairwise comparisons of type n×n (n≥ 2) with the solution vector w that represents the probability components of disjoint events. Moreover, we suggest an algorithm for the determination of the eigenvalue problem solution Aw=nw as well as the corresponding flowchart. The algorithm for arbitrary consistent matrix A can be simply programmed and used.

“…A review of these applications has been done for example by Vaidya and Kumar [23]. With respect to mining-related problems, noteworthy AHP applications include [24][25][26][27][28][29]. Dey and Ramcharan [24] proposed an AHP based analytical framework for site selection for the expansion of a limestone quarry operation, Ptak [25] employed AHP to construct an evaluation method for the assessment of rock mineral deposits whose development could affect Nature 2000 areas, Gupta and Kumar [26] examined the application of AHP for the selection of an appropriate stoping method for mining underground ore deposit, Sobczyk and Badera [27] studied the possibilities of predicting which of the specified hard coal deposits are relatively less contentious with regard to local economic, social and environmental determinants, Blachowski [28] used AHP in combination with GIS to assess the accessibility of a brown coal deposit for development with respect to environmental and land use functions, and Malinowska and Matonóg [29] tried to estimate the sinkhole hazard in former and present mining areas with AHP.…”

The Lower Silesia area in SW Poland is characterized by a geological structure that is conducive to mining activity. The exploitation of rock raw materials plays an important role in this sector of the economy. By the end of 2017, there were in total approximately 400 current concessions for the exploitation of rock raw materials in the analysed area (Polish Geological Institute, MIDAS database—Management and Protection System of Polish Mineral Resources). The conducted mining activity results in waste, which in the greatest amount occurs in the process of obtaining crushed road and construction aggregates, natural aggregates, carbonate raw materials for the cement and lime industry, as well as stone elements for construction and road engineering. At the end of 2016, the mining plants accumulated 26,569,600 Mg of waste. As part of the European Regions Toward Circular Economy (CircE) project, research was conducted on the volume and composition of the mining waste of rock raw materials in the years 2010–2016 within Lower Silesia. This research used the methods of statistical, descriptive and spatial analysis to identify mining plants with the highest potential for using their wastes. In the course of this study, 6 mining plants with the highest potential of using their waste for industrial production purposes were selected. In order to objectively select these plants, the methodology of qualitative multi-criteria analysis was developed, and 7 criteria were selected for assessing the economic potential of using waste from the mining of rock raw materials. An additional result of this research is a database and graphical presentation of changes in the spatial distribution of generated waste in the Lower Silesia region in the years ranging from 2010 to 2016.

“…In this research, the fuzzy logic method based on WLC was used to combine various data layers. In order to conduct environmental capability evaluation using this method, according to function (3) (Eastman 2006), each standardized layer needed to be multiplied by the final weight that was related to it, and at the end, all layers were to be added up (Blachowski 2015).…”

Environmental capability evaluation for nuclear power plant site selection: a case study of Sahar Khiz Region in Gilan Province, Iran

2016

Due to the increasing population and the growing need for providing energy from a clean and non-fossil resource, there is an increasing interest in nuclear energy all over the world. As a fact, environmental capability evaluation should be considered for establishment of new nuclear power plants, not only to increase the safety against environmental risks, but also to achieve sustainable development. This study focuses on environmental capability evaluation for the nuclear power plant site selection in the coastal area of Gilan Province (Sahar Khiz). Considering the natural potentials and limitations of the area, the existing laws and regulations set by the International Atomic Energy Agency, United States Nuclear Regulatory Commission and Department of Environment, ecological and socioeconomic criteria were the main object of this study. At first, the Boolean logic method was used to prepare layered maps and identify selected zones, using geographical information system (GIS) and the ''AND'' operator. Then, the fuzzy logic method based on weighted linear combination (WLC) was applied for site selection of the new nuclear power plant. Four main criteria (physical, biological, social and economic) and 15 sub-criteria have been chosen for site selection process, from all selected criteria and sub-criteria. After preparing the raster maps of the ecological and socioeconomic sub-criteria, the fuzzy logic was used to standardize data layers between zero and one. Then, a relative weight was assigned to each criterion using Expert Choice software and the analytical hierarchy process (AHP) method. At the end, to combine all subcriteria, fuzzy logic method based on WLC was used in GIS environment, and the final map of environmental capability was prepared. The results of this study were compared to the results using the Boolean logic method, showing high coverage between the two methodologies, while the fuzzy logic method based on WLC combined with the AHP method had more flexibility and more accuracy comparing with the Boolean logic method.
