Reliable detection of underground infrastructure is essential for infrastructure modernization works, the implementation of BIM technology, and 3D cadasters. This requires shortening the time of data interpretation and the automation of the stage of selecting the objects. The main factor that influences the quality of radargrams is noise. The paper presents the method of data filtration with use of wavelet analyses and Gabor filtration. The authors were inspired to conduct the research by the fact that the interpretation and analysis of radargrams is time-consuming and by the wish to improve the accuracy of selection of the true objects by inexperienced operators. The authors proposed automated methods for the detection and classification of hyperboles in GPR images, which include the data filtration, detection, and classification of objects. The proposed object classification methodology based on the analytic hierarchy process method introduces a classification coefficient that takes into account the weights of the proposed conditions and weights of the coefficients. The effectiveness and quality of detection and classification of objects in radargrams were assessed. The proposed methods make it possible to shorten the time of the detection of objects. The developed hyperbola classification coefficients show promising results of the detection and classification of objects.

Abstract The number of cloud services has dramatically increased over the past few years. Consequently, finding a service with the most suitable quality of service (QoS) criteria matching the user’s requirements is becoming a challenging task. Although various decision-making methods have been proposed to help users to find their required cloud services, some uncertainties such as dynamic QoS variations hamper the users from employing such methods. Additionally, the current approaches use either static or average QoS values for cloud service selection and do not consider dynamic QoS variations. In this paper, we overcome this drawback by developing a broker-based approach for cloud service selection. In this approach, we use recently monitored QoS values to find a timeslot weighted satisfaction score that represents how well a service satisfies the user’s QoS requirements. The timeslot weighted satisfaction score is then used in Best-Worst Method, which is a multi-criteria decision-making method, to rank the available cloud services. The proposed approach is validated using Amazon’s Elastic Compute Cloud (EC2) cloud services performance data. The results show that the proposed approach leads to the selection of more suitable cloud services and is also efficient in terms of performance compared to the existing analytic hierarchy process-based cloud service selection approaches.

The quality of ground surface pregrouting (GSPG) is commonly qualitatively evaluated using single factor; however, the quality evaluation involves numerous facets, and a quantitative evaluation is rare. The aim of this study was to quantitatively evaluate the quality of a GSPG based on three aspects. The fuzzy analytic hierarchy process (FAHP) was adopted to obtain the final score and quality classification of the GSPG. Based on three aspects, namely, integrity, continuity, and sturdiness, a series of field tests was also conducted, qualitatively evaluating the quality of the GSPG preliminary, to obtain the required test data and verify the FAHP results. The results of the FAHP showed that the quality of the GSPG was 86.42, which could be classified as “Good”, whereas the field tests exhibited that the GSPG was effective, thereby verifying that the FAHP was reliable. In addition, the proposed method provided a detailed comprehension of the quality evaluation of GSPG and a frame of reference for analogous engineering.

Purpose The purpose of this paper is to bridge the gap between physical and metaphysical entities in the context of product/system design. The paper talks about the grey area of human psychology and presents a theoretical framework for the identification and selection of psychological attributes for designers. Design/methodology/approach On the basis of a literature review, this paper identifies various psychological attributes affecting the performance of designers in a team environment and then analyses the same. Findings The paper talks about a new shift in engineering design and designs for maintainability of mechanical systems. Practical implications A procedure based on the analytic hierarchy process method is applied. The developed procedure is useful in the assessment and selection of coveted psychological attributes for personnel in general and for designers in particular. Originality/value The paper highlights the immense role of psychology in engineering design, especially in the design for maintainability of mechanical systems. The paper will be useful to researchers, designers, maintenance personnel and professionals from the domain of engineering design, irrespective of their field of application. This paper is equally useful for human resource and management professionals/researchers.

The process of selecting a drawing coloring tool in one of the Cianjur city painting studios takes a long time, because the child must first try each type of drawing coloring tool. based on this problem discussed about the selection of coloring tools for beginners by using the Analytic Hierarchy Process (AHP) and Product Weight (WP) methods.  AHP test results obtained five criteria, namely comfort, convenience, safety, color quality and product quality of the ten recommended criteria based on observations and interviews. The five criteria are used as criteria for determining the selection of drawing tools for crayons, colored pencils, watercolors, markers, and oil pastels. the final result of the calculation of the Analytical Hierarchy Process (AHP) method shows that crayons are the most important alternative with a weight value of 0.20. while the test results of the Weighted Product (WP) method conclude that the brand code V4 is the crayon product brand chosen because the brand code V4 has the highest alternative value of the other ten products namely V4 = 0.118.

A groundwater control system was designed to lower the water table and allow the pumping station ?Bezdan 1? to be built. Based on a hydrodynamic analysis that suggested three alternative solutions, multicriteria optimization was applied to select the best alternative. The fuzzy analytic hierarchy process method was used, based on triangular fuzzy numbers. An assessment of the various factors that influenced the selection of the best alternative, as well as fuzzy optimization calculations, yielded the ?weights? of the alternatives and the best alternative was selected for groundwater control at the site of the pumping station ?Bezdan 1?.
