Assessing/ranking the innovative advantages of countries is a problem of current interest. However, the set of tools used for this purpose are very narrow and often prone to criticism. The aim of this study is to somewhat extend the arsenal of methods used to this end. For this purpose, based on a data set from the Global Innovation Index, this study develops a special multi-objective decision-making problem, the aim of which is to identify the “best countries” in the sense of their innovative advantage. Moreover, applying ranking methods (in our case the Markov-chain method and analytic hierarchy process) to this multi-objective decision-making problem, we obtain new alternative ratings/rankings of the innovative advantages of countries.

The state of Himachal Pradesh in India is one of the most important hotspots when it comes to landslides; and Kandaghat, a tehsil in the Solan district of Himachal Pradesh having religious and tourism importance, is substantially affected by frequent landslides causing road blocking. In the present study, the analytic hierarchy process (AHP) and certainty factor (CF) techniques, which form part of the geographic information system (GIS)-based landslide susceptibility models, were used to prepare a landslide susceptibility map for the Kandaghat region, for which, as a preliminary step, an inventory of 214 live landslides was prepared from the Bhukosh data directory. The landslide inventory was cross-verified on the Google Earth platform. About nine landslide causative factors (slope, curvature, aspect, soil, rainfall, land use–land cover, lithology, drainage density and lineament density) were considered for the study area, and against the backdrop of these, the corresponding thematic maps were prepared and used in turn for the preparation of the final landslide susceptibility map. Based on the two mentioned techniques, the thematic maps were assigned weights according to their prominence and dynamic processes in the study area. The model performance for each method was evaluated using the area under the curve (AUC), and the accuracies for the AHP and CF were ascertained as, respectively, 81% and 85.6%. The Himalayan terrains are significantly prone to landslides, and this study outlines the characteristics of one of the important Himalayan towns in terms of vulnerability for landslides, together with providing its classification in terms of slope deformation susceptibility; this procedure can help direct attention towards areas needing to be classified under high to very high landslide susceptibility zones.

Due to the indiscriminate use of limited water sources, the requirement for groundwater evaluation in India expanded substantially. Population growth and unequal distribution, poor irrigation systems, rapid urbanization/industrialization, large-scale deforestation, droughts, and inefficient land use practises contribute to groundwater depletion.As a result, the need for water for agriculture, domestic, and industry soars. The study identifies viable zones in Visakhapatnam’s emerging metropolitan metropolis by utilising the Analytical Hierarchy Process (AHP) approach with remote sensing data in ArcGIS software. Thematic layers were created by taking remote sensing data into consideration (drainage density, soil, lineament density, land use land cover, geomorphology, rainfall, slope, and geology). The method is employed to determine the weights of distinct thematic layers by obtaining the normalised weight from a pairwise matrix.To emphasize the groundwater potential zones and create a map with different zones specified, the weights and ranks extrapolated from the AHP approach have been made available in the weighted index overlay analysis tool in ArcGIS.Groundwater availability and recharge are significantly high in the good zone of the present study’s four classifications of good, moderate, low, and very low. The groundwater status, potential locations for water extraction, and best practises for groundwater recharging may all be determined with the use of the acquired information from the indication map.

Successful mine planning is necessary for the sustainability of mining activities. Since this process depends on many criteria, it can be considered a multi-criteria decision making (MCDM) problem. In this study, an integrated MCDM method based on the combination of the analytic hierarchy process (AHP) and the technique for order of preference by similarity to the ideal solution (TOPSIS) is proposed to select the optimum mine planning in open-pit mines. To prove the applicability of the proposed method, a case study was carried out. Firstly, a decision-making group was created, which consists of mining, geology, planning engineers, investors, and operators. As a result of studies performed by this group, four main criteria, thirteen sub-criteria, and nine mine planning alternatives were determined. Then, AHP was applied to determine the relative weights of evaluation criteria, and TOPSIS was performed to rank the mine planning alternatives. Among the alternatives evaluated, the alternative with the highest net present value was selected as the optimum mine planning alternative. It has been determined that the proposed integrated AHP-TOPSIS method can significantly assist decision-makers in the process of deciding which of the few mine planning alternatives should be implemented in open-pit mines.

Although new techniques are added to multi-criteria decision-making (MCDM) techniques every day, fuzzy applications of current and proven methods also take a large place in the literature. The main subject of this study is to propose an extension of Pythagorean fuzzy sets (PFS), which are useful to overcome the uncertainty in multi-criteria decision processes, to the well-known Analytical Network Process (ANP) technique. For this purpose, an empirical application of the proposed method was carried out in defining criteria weights of the warehouse location selection problem in the medical sector.

In the contemporary period of the green economy, energy planning has grown more complicated due to the inclusion of numerous standards, including technical, social, economic, and environmental. This, in turn, restricts the ability of decision-makers to make the most efficient use of energy resources. In addition, the difficulty of energy planning is exacerbated by topographical restrictions on renewable energy systems, the majority of which are found in nature. Based on factors such as total installed capacity, total reservoir capacity, total surface capacity, the height, length, number of units, and the cost of the dam were used to determine the finest hydro power project in India, according to this study. For performance evaluation, multi criteria decision making (MCDM) techniques like analytic hierarchy process (AHP) and TOPSIS (technique for order reference by similarity to ideal solution) are used in conjunction with VIKOR (vlekriterijumsko kompromisno rangiranje) for performance evaluation. AHP is used to calculate the weights of each criteria. The TOPSIS and VIKOR methods will utilise these weights to choose the optimal option. For the purpose of demonstrating the approaches’ applicability, an in-depth case study of various hydropower facilities in India was carried out.

Wybór optymalnego rozwiązania oparto na kryterium zrównoważonego rozwoju. Zaproponowane metody: hierarchiczna metoda AHP i metoda programowania kompromisowego, mogą być wykorzystywane do wyboru najlepszego rozwiązania na etapie planowania systemu usuwania i oczyszczania ścieków w wiejskich jednostkach osadniczych, z uwagi na to, że analiza i wybór rozwiązania systemu usuwania i unieszkodliwiania ścieków z terenów wiejskich jest skomplikowanym zadaniem decyzyjnym, które powinno być ocenione w wielu różnorodnych aspektach, przy użyciu różnych kryteriów i mierników.

The article presents a proposal for decision analysis application to the selection process for the removal and treatment of sewage in rural areas. Selecting the optimal solution was carried out based on the criteria of sustainable development. The proposed methods: hierarchical method of AHP and compromise programming can be used to choose the best solution at the planning stage removal system and wastewater treatment in countryside settlements, due to the fact that the analysis and the choice of system solutions removal and disposal wastewater in rural areas is a complicated task decisionmaking, which should be evaluated in many different aspects, adopting various criteria and measuring instruments.
