Flood modeling provides useful information to assist manage flood hazards and lessen the effects of floods in locations that are vulnerable to flooding. The present research established flood hazard maps for the Ngan Sau, Ngan Pho river basin using GIS technology and the Analytical Hierarchy Process (AHP) method. The precision of flood simulation results is dependent on criteria that cause flooding. The goal of this study was to evaluate the role of relative slope length in flood hazard identification and delineation. The AHP method was used to determine the respective weights of six physical geography and meteorology factors including rainfall, slope, soil, land use, drainage density, and relative slope length. In the process of computing the model, these factors are classified into two groups: group 1 includes five criteria excluding the relative slope length criterion and group 2 has all six parameters. Based on flood warning levels at hydrological stations in the research area during past floods, the results of flood hazard zoning were verified. The obtained findings indicated that map developed from the group of criteria including the relative slope length are more accurate than those generated based on the remaining five factors. The results of the paper can be used as a reference when choosing criteria for creating flood hazard zoning models utilizing a combination the AHP and GIS technology.

Modelowanie powodzi dostarcza przydatnych informacji, które pomagają zarządzać zagrożeniem powodziowym i łagodzić skutki powodzi w lokalizacjach narażonych na powodzie. W ramach niniejszych badań opracowano mapy zagrożenia powodziowego dla dorzeczy rzek Ngan Sau i Ngan Pho przy użyciu technologii GIS i metody Analytical Hierarchy Process (AHP). Dokładność wyników symulacji powodzi zależy od kryteriów powodujących powódź. Celem pracy była ocena roli względnej długości zbocza w identyfikacji i wyznaczaniu zagrożenia powodziowego. Do określenia odpowiednich wag w AHP wykorzystano sześć czynników geograficznych i metrologicznych — opady deszczu, nachylenie, gleba, użytkowanie gruntów, gęstość drenażu i względna długość zbocza. W procesie obliczania modelu czynniki te dzielone są na dwie grupy: grupa 2 obejmuje wszystkie sześć parametrów, natomiast grupa 1 obejmuje pięć kryteriów z wyłączeniem kryterium względnej długości nachylenia. W oparciu o stany ostrzeżeń powodziowych na stacjach hydrologicznych na obszarze badań podczas powodzi, które miały miejsce w przeszłości, zweryfikowano skutki wyznaczania stref zagrożenia powodziowego. Uzyskane wyniki wykazały, że mapy opracowane z grupy kryteriów uwzględniających względną długość nachylenia są dokładniejsze niż mapy wygenerowane na podstawie pozostałych pięciu czynników. Wyniki artykułu mogą posłużyć jako punkt odniesienia przy wyborze kryteriów tworzenia modeli stref zagrożenia powodziowego z wykorzystaniem kombinacji tech-nologii AHP i GIS.

Road construction has been an ongoing engineering practice throughout human history. Although road construction technologies have changed over time, the raw material used has not changed for centuries, and it seems that it will not change in the upcoming centuries. Although some standards are used to determine the aggregate quality in road construction works, it is often complex and laborious to identify the aggregates that best meet the standards. Long-lasting and high-quality roads can be built and the most suitable aggregate is selected for the road. This study aims to select the most suitable aggregates used in hot-mix asphalt pavement production for road construction. In this study, multi-criteria decision-making methods were used for the selection of the aggregate that provides the best conditions. Aggregates used in constructing roads within the provincial borders of Ankara are produced from six stone quarries. To rank these aggregates and determine the ideal quarry for hot-mix asphalt production, the analytical hierarchy process (AHP) and the technique for order preference by similarity to an ideal solution (TOPSIS) method, which are multi-criteria decision making (MCDM) methods, were used. The results obtained from the tests on aggregates and hot-mix asphalts (HMA) were compared with the the best results based on the maximum and minimum limits determined in the standards. By comparing the the best results of the standards with the test results of the aggregates, weight scores were made for each test. Weight scores were scored and classified using the AHP and TOPSIS multi-criteria decision-making methods. As a result, the aggregate with the highest score and the quarry area represented by the aggregate were determined as the most suitable for hot-mix asphalt construction.

Budowa dróg była stałą praktyką inżynierską w całej historii ludzkości. Choć technologie budowy dróg zmieniały się na przestrzeni dziejów, to stosowany surowiec nie zmienia się od wieków i wydaje się, że nie zmieni się w kolejnych stuleciach. Chociaż niektóre normy są stosowane do określania jakości kruszyw w robotach drogowych, to często skomplikowane i pracochłonne jest uszeregowanie kruszyw spełniających te normy. Trwałe i wysokiej jakości drogi można budować przy użyciu najodpowiedniejszego kruszywa dobranego do drogi. Niniejsze opracowanie ma na celu wybór najodpowiedniejszych kruszyw do produkcji nawierzchni asfaltowych na gorąco do budowy dróg. W niniejszym badaniu zastosowano wielokryterialne metody decyzyjne do wyboru agregatu, który zapewnia najlepsze warunki. Kruszywa wykorzystywane do budowy dróg w granicach prowincji Ankary produkowane są w sześciu kamieniołomach. Aby uszeregować te agregaty i określić idealny kamieniołom do produkcji gorącej mieszanki asfaltowej, zostały użyte: analityczny proces hierarchiczny (AHP) i technika preferencji zamówień na podstawie podobieństwa do metody idealnego rozwiązania (TOPSIS), które są metodami wielokryterialnego podejmowania decyzji (MCDM). Wyniki uzyskane z badań kruszyw i asfaltów na gorąco (HMA) porównano z najlepszymi wynikami wynikającymi z maksymalnych i minimalnych limitów określonych w normach. Porównując najlepsze wyniki wzorców z wynikami testów agregatów, dla każdego testu wykonano oceny wagowe. Oceny wagowe zostały ocenione i sklasyfikowane przy użyciu wielokryterialnych metod podejmowania decyzji, AHP i TOPSIS. W rezultacie kruszywo z najwyższą punktacją i obszar kamieniołomu reprezentowany przez kruszywo zostały uznane za najbardziej odpowiednie do budowy gorących mieszanek mineralno-asfaltowych.

The use of robotic equipment and a new technique called contour crafting allows for the construction of buildings at lower labor and material costs. The selection of the type of robot is an important factor that affects the overall performance of the contour crafting (CC) system. Various robot configurations, such as gantry, cylindrical, and SCARA, may be employed for contour crafting. There are benefits and drawbacks to using different types of robots for various tasks, including cost, work volume, material compatibility, and precision. Identifying a proper robot using the multi-criterion decision-making (MCDM) technique is crucial for successful building automation. This article uses the analytical hierarchy process (AHP) method to rank the best robots according to several characteristics. Cartesian robots, cylindrical robots, and SCARA robots were evaluated based on cost, accuracy, work volume, surface finish, type of profile, and speed. The results showed that the gantry-type robot is the most suitable option, while the cylindrical robot is unsuitable for building construction due to lower accuracy.

Cost overrun during construction is one of the most common problems occur in construction projects around the world, which also includes the area of Chongqing in China. At present, there are few studies related to cost overruns at the construction stage of high-rise residential building projects (HRBPs) in Chongqing. The purpose of this study is to develop effective control measures from the contractor’s perspective to help projects to minimize cost overruns during the construction phase of HRBPs in Chongqing. Firstly, through the literature review and semi-structured interviews, 65 cost overrun-related risk factors in construction projects were identified. All the risk factors have been prioritized through the analytic hierarchy process (AHP) based on their importance to project success. Out of the 65 factors identified, 12 were classified as the critical ones that have a great potential to instigate a cost overrun during construction to take place in the real project. There were four risk factors that have the greatest impact on cost overruns, and their weights were 0.04 or above, including low bid, force majeure, undetailed/inaccurate geological survey data, and increased loan interest rates. Finally, control measures were developed for these four critical cost overrun risk factors (CCORFs). The measures developed provided a guideline to control the risk of cost overruns and clear control key points to help contractors minimize cost overruns on construction projects.

The article presents selected types of phase change materials (PCM) and their properties in terms of applications in construction and concrete technology. The purpose of using PCM is to allow the technological barrier to be exceeded in hot and dry climate conditions, enabling the construction of non-cracking concrete structures. Methodology of the multi-criteria decision-making process with the use of a relatively new decision-making tool in construction - the Analytical Hierarchical Process (AHP) is presented. Theoretical aspects of the method and an example of its practical use for the selection of the best material variant and concrete care method in the dry Syrian climate are presented. The conclusions resulting from the presented article concern two areas, i.e. the advisability of using phase change materials for temperature regulation in the maturing fresh concrete in dry climate conditions and the attractiveness of the AHP method justifying the advisability of choosing the maintenance methods in such conditions.

Water scarcity and soil erosion are the main constraints small holder farmers are facing in Tigray, the northern most part of Ethiopia. Both very high and very low precipitation can cause a damage to agriculture which is the case in semi-arid regions like Tigray. While too little rainfall cannot support the growth of crops resulting in crop failure, the short but intense rainfall also causes a runoff thereby washing away essential soil nutrients. Installation of different micro/macro-catchment rainwater harvesting can address both water scarcity and soil erosion if they are properly designed prior to construction. This research was intended to develop a methodology for identifying suitable rainwater harvesting (rwh) sites by using weighted overlay analysis. It also utilizes Ahp (analytical hierarchy process) as effective multi-criterion decision-making tool in eastern Tigray at Kilte Awlaelo district on an area of 1001 km2 . This method was chosen because it is simple to use, cost effective, flexible and widely adopted. Physical, hydrological, climate and socio-economic aspects were taken into account during criteria selection. The result indicated four suitability classes with 8.74% highly suitable areas (85.25 km2 ), 56% suitable areas (550.75 km2 ), 30.8% moderately suitable areas (303.2 km2 ) and 4.46% less suitable areas (43.87 km2 ). The produced rwh suitability map was also validated by both ground truth on google earth pro and a field trip to the study site. In situ and ex situ rwh including bench terraces, wells, and enclosure areas were identified during the field visit that verified the suitability model. Finally, depending on weight and scale of criteria and sub-criteria that matched to each identified suitable areas, different micro-catchment and macro-catchment techniques of water harvesting are recommended. This methodology can be utilized as decision-making tool for rwh practitioners, local and foreign organizations working on soil water conservation programmes and policy-makers during their early planning stages.

Groundwater can serve as an alternative measure to solve the scarcity in perennial water sources. In this perspective, a study has been carried out in Phuentsholing, Bhutan, for demarcating the most probable zone for groundwater source by an integrated application of geospatial and geophysical survey. The seven contributing factors (i.e. geology, geomorphology, drainage, landuse landcover (LULC), normalized difference vegetation index (NDVI), lineament, and slope are evaluated. Subsequently, an Analytic Hierarchy Process (AHP) is also carried out to normalize the weightage and rank of the individual factors, which are further overlaid using the Weighted Index Overlay (WIO) algorithm. The resultant groundwater potential was categorized into: extremely high (0.7%), high (54%), moderate (12.5%), low (21%), and extremely low (12%) potential zones. Each of this category is further validated by Vertical Electrical Sounding (VES-3) using Schlumberger electrode configuration and identified the most probable groundwater exploration zones towards the south-western parts of the study area. Thus, the study emphasizes on significant role of remote sensing and geographic information system (GIS) in aggregation with the geophysical and statistical measures to delineate the most probable location for groundwater resources in the Himalayan region.

The subcontractor selection decision is inherently a multicriterion problem. It is a decision of strategic importance for companies. The nature of this decision is usually complex and unstructured. Management science techniques might be helpful tools for solving these kinds of decision-making problems. In this research, the fuzzy logic method and the analytic hierarchy process were applied for the selection of suitable subcontractors in an apparel supply chain. In general, many factors, such as quality level, price offer, and delivery delay, were considered to determine the most suitable and reliable subcontractors that fit the company's strategy. This survey is carried out using the database of an apparel company manufacturing denim products.

Humanity is one of the most important resources for businesses. Because, with human resources, the data of the institution can be obtained and information can be produced by processing. Thus, human resources make the business a learning and dynamic organization and ensure its continuity. In enterprises, personnel selection (in terms of quantity or quality) is carried out within the scope of Human Resources Management. This selection process usually takes place when a group of decision makers evaluates the candidates according to some criteria and their own opinions. However, this situation prevents an objective and fair selection. For this reason, in this study, a decision support system (DSS) has been developed by using the Analytical Hierarchy Process (AHP), one of the Multi-Criteria Decision Making (MCDM) methods, to ensure objectivity and to select the most suitable personnel for the job description. The said DSS provides the selection of the marketing manager among the personnel working in an enterprise. For this, the 10 employees working in the marketing department of the enterprise for the longest time were taken into account. When the results are examined, it is seen that the most qualified personnel can be selected successfully in cases where customer satisfaction, performance value and number of projects are prioritized

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.

Rational solution for mining equipment based on the use of haul trucks, excavators, wheel loaders and crunchers should result from thorough analysis of technical and economic issues – both cost-related and exploitational - which can have a crucial impact on the cost of minerals extraction. Moreover mining equipment should be selected with consideration for all vital parameters in specific exploitational conditions and even the exploiter’s preferences. This selection should consider hitherto disregarded criteria, such as mean availability and structure utilization of machinery systems with the aim to improve the same. Methodology presented in the paper illustrates practical application of MCDM and one particular method of this type – the Analytical Hierarchy Process (AHP) – for resolving the problem in specific exploitational conditions of mineral resource in surface mining AHP method covers a multi-criteria approach based on a compensation strategy to model preferences and assuming variant comparability. Taking into account the preferences of the evaluator, which determine the subjectivity of comparative evaluation, is the core of the multi-criteria approach, which treats such preferences Considering the above issues, the following paper is an attempt to develop new and universal criteria as well as a method of evaluation and selection of means of mining equipment for mineral resource surface mines.

Risk scoring methods applied in risk assessments used in Turkey, differ from each other in terms of analysis methods, scoring the risks, presumption and sensitivity levels. This article aims to eliminate the effects of divergent results of different risk analyses of lifting equipments used in the building industry and develop a practical hybrid risk analysis and ranking method. In this study risks of lifting equipments used in the building industry were scored by conventional Fine-Kenney risk analysis method first. Secondly, with the experience of previous accidents on construction sites, the reasons of accidents were sorted into 7 main criteria, which being ‘Demographic’, ‘Behavioral’, ‘Machine Related’, ‘Working Environment Related’, ‘Economical’, ‘Administrative’ and ‘Organizational’ criteria and related sub-criteria. Developing these criteria was supported by the experience of inspections carried out by labour inspectors. The weighted scores of these criteria were calculated by AHP method using a questionnaire applied to 14 experienced labor inspectors. The weighted scores obtained by the analytical hierarchy process method (AHP) were multiplied by the scores obtained by Fine-Kinney risk assessment method and a new integrated risk assessment and ranking application was introduced. With this application, a different priority rank was created and which risk to be eliminated primarily was determined. Keywords: analytical hierarchy process, lifting equipments, fine-kinney, occupational health and safety, integrated risk analysis, ranking method

In the fast-changing internet era, private sale websites attracted an enormous interest from the consumers in especially online marketing of apparel goods. The retailers may garner more benefit if the prior issues for the consumers when they are purchasing apparel products online is known. Reviewing the literature, this study presents the factors in three groups in a hierarchical manner considering the multidimensional aspect of online purchasing of apparel products from private sale websites and then determines the prior issues for the consumers by making pairwise comparisons among these factors using analytical hierarchy process on a sample group of 100 Turkish respondents. The findings revealed that “privacy/security” in terms of online shopping criteria, “product information” in terms of apparel products criteria, and “discount ratio” in terms of private shopping criteria took highest scores of importance when the aspects were analyzed individually. Nonetheless, the parameters regarding the online shopping criteria were found to be more important than the criteria regarding the apparel products and private shopping criteria. In the end, it was also observed that these items that were found to have highest importance were actually corresponding to the risks of the situation.

This article is devoted to some problems connected with multicriteria decision analysis. We consider the relationship between the pairwise comparison matrix (PCM) and a priority vector (PV) obtained on the basis of this matrix. The PCM elements are the decision makers’ judgments about priority ratios i.e. the ratios of weights contained in the PV. It is known, that in the case of consistent matrix, we can obtain the exact value of related PV. However, the real-world practice shows that the decision maker does not create a perfectly consistent PCM, and thus usually in such a matrix the judgment’s errors occur. In our paper we use Monte Carlo simulation to study the relationship between various possible distributions of these errors and the distributions of the errors in estimates of the true PV. In these simulation we apply some initial families distribution and some different parameters. We obtain interesting results which show very slight influence families distribution on final PV errors. Our paper show that much bigger influence on simulation result have adopted parameters than selection distribution family.

Green issues are a popular topic in today’s business life, and it is possible to see green products or advertisements in many different places due to the demand for a healthier lifestyle. Companies that are willing to be a part of the green concept should integrate this philosophy in all departments. As a result, the procurement might be seen a crucial part of this integration. However, in the emerging markets, green issues might be pushed into the background due to the competitive environment. In this study, we investigated green and other parameters in the supplier selection decision in textile industry. A decision criteria list was created and evaluated by 28 experts using the fuzzy analytic hierarchy process. The results showed that green issues have an influence on the decision environment; however, classical parameters, such as cost, delivery reliability, quality, service, and strategic alliance still carry more priority compared to green criteria consisting of environmental management, green products, and pollution control.

Over the past twenty years, the number of vehicles registered in Poland has grown rapidly. At the same time, a relatively small increase in the length of the road network has been observed. As a result of the limited capacity of available infrastructure, it leads to significant congestion and to increase of the probability of road accidents. The overall level of road safety depends on many factors - the behavior of road users, infrastructure solutions and the development of automotive technology. Thus the detailed assessment of the importance of individual elements determining road safety is difficult. The starting point is to organize the factors by grouping them into categories which are components of the DVE system (driver - vehicle - environment). In this work, to analyze the importance of individual factors affecting road safety, the use of analytic hierarchy process method (AHP) was proposed. It is one of the multi-criteria methods which allows us to perform hierarchical analysis of the decision process, by means of experts’ opinions. Usage of AHP method enabled us to evaluate and rank the factors affecting road safety. This work attempts to link the statistical data and surveys in significance analysis of the elements determining road safety.

Na przestrzeni ostatnich dwudziestu lat liczba pojazdów rejestrowanych w Polsce dynamicznie rośnie. Jednocześnie obserwowany jest stosunkowo niewielki wzrost długości sieci drogowej. W wyniku ograniczonej przepustowości dostępnej infrastruktury prowadzi to do znacznego zatłoczenia i zwiększenia prawdopodobieństwa wystąpienia zdarzeń drogowych. Na ogólny poziom BRD wpływa wiele czynników – zachowania uczestników ruchu, rozwiązania dotyczące infrastruktury, a także rozwój techniki motoryzacyjnej. Szczegółowa ocena istotności poszczególnych elementów determinujących stan BRD jest więc trudna. Punktem wyjścia jest uporządkowanie czynników przez grupowanie do kategorii skumulowanych stanowiących składowe systemu UPO (uczestnik ruchu drogowego – pojazd – otoczenie). W niniejszym artykule do analizy istotności poszczególnych czynników wpływających na stan BRD zaproponowano wykorzystanie metody analitycznego procesu hierarchicz-nego (AHP). Jest to jedna z metod wielokryterialnych, która pozwala na hierarchiczną analizę problemu decyzyjnego na podstawie opinii eksperckich. Wykorzystanie metody AHP umożliwiło ocenę i uszeregowanie czynników wpływających na stan bezpie-czeństwa ruchu drogowego. Artykuł stanowi próbę powiązania danych statystycznych i ankietowych w ramach analizy istotności elementów determinujących BRD.

Weryfikację przeprowadzono na podstawie strukturalizowanego wywiadu z wybranymi dziewięcioma uczelniami publicznymi. Otrzymane oceny wykazały, że większość badanych postrzegało opracowaną platformę jako dobrą (65%) lub doskonałą (21%) pod względem wydajności, przydatności i wiarygodności. Przewiduje się, że proponowany framework wspomagający podejmowanie decyzji będzie stanowić użyteczne narzędzie doboru odpowiednich metod przetargowych dla instytucji zajmujących się obsługą techniczną.
