Use of analytical hierarchy process for selecting and prioritizing islanding detection methods in power grids

One of the problems that are associated to power systems is islanding condition, which must be rapidly and properly detected to prevent any negative consequences on the system's protection, stability, and security. This paper offers a thorough overview of several islanding detection strategies, which are divided into two categories: classic approaches, including local and remote approaches, and modern techniques, including techniques based on signal processing and computational intelligence. Additionally, each approach is compared and assessed based on several factors, including implementation costs, non-detected zones, declining power quality, and response times using the analytical hierarchy process (AHP). The multi-criteria decision-making analysis shows that the overall weight of passive methods (24.7%), active methods (7.8%), hybrid methods (5.6%), remote methods (14.5%), signal processing-based methods (26.6%), and computational intelligent-based methods (20.8%) based on the comparison of all criteria together. Thus, it can be seen from the total weight that hybrid approaches are the least suitable to be chosen, while signal processing-based methods are the most appropriate islanding detection method to be selected and implemented in power system with respect to the aforementioned factors. Using Expert Choice software, the proposed hierarchy model is studied and examined.

Supplier Selection Modeling and Analysis in the Metal Casting Industry Using Analytical Hierarchy Process

This study presents a supplier selection problem of a raw material using an analytical hierarchy process. In the existing process, the delivery of raw materials experienced delays and impacted the production process. Therefore, this paper aims to determine the criteria for supplier selection and provide recommendations for the best vendor to be selected from the last request for quotation document. Analytical Hierarchy Process (AHP), as a multi-criteria approach, was utilized in this research, starting from determining criteria, the weight of criteria, and the final score for each supplier. Through discussions with the company’s expert, procurement department, and users, as well as a review of the previous studies, this research defined three criteria, each consisting of three sub-criteria. The AHP approach was utilized to evaluate and determine the weights for the three criteria, yielding the following results: quality (62%), price (28%), and delivery (10%). The identified criteria, sub-criteria, and respective weights are subsequently utilized in a supplier selection scenario. Three suppliers of mild steel raw materials were evaluated using the weights of the criteria and sub-criteria obtained. Supplier 1 was selected because of having the higher alternative value of 0.602. The use of AHP in supplier selection is often impractical and contains subjectivity. Therefore, further research can be performed by integrating AHP with other methods, such as weighted scoring, to facilitate further the vendor selection process and integration with other methods, such as fuzzy logic, to reduce subjectivity.

A Prioritization Method to Optimize School Operational Assistance Fund by Using AHP Approach

In Indonesia, education funding provided by the central government is made up of the components of personnel costs, investment costs, and operating costs. Since its implementation in 2005, the program has found several obstacles. It’s crucial to have an optimization tool to overcome the complications. The main problems that have arisen in the allocation of these funds so far have been lacking in planning and the lack of participation of the school ecosystem, in particular in determining the planning, planning documents and the priority scale of the projects. Program and activity plans based on the School Operating Assistance (BOS) platform. The Analytical Hierarchy Process (AHP) model is a prioritization approach based on determining the priority scale on the comparison of one option with another. The AHP model is a powerful but simple method that is usually used to make decisions. This approach has been implemented in various sectors, business, government, management, and education. In this study, the AHP model was used to determine the priority scale on the criteria of BOS allocated funds in the current year so that it could be absorbed optimally and can be utilized properly in its implementation for Vocational School activities. The results of the study show that the use of AHP makes it easier for school residents to prioritize the use of funds for school activities. Using the AHP model allows managers to record strategic goals using weighted criteria as the basis for prioritizing the use of funds. AHP can also work among different stakeholders in the school (principals, treasurers, teachers, and committee, parents/guardians) to participate in decisions about the use of BOS funds, to improve the quality and form of decision support taken to improve school performance.

Hierarchizing the Criteria of Construction Equipment Procurement Decision Using the AHP Method

Successful investment in construction equipment (CE) is a complex process as it involves the selection and prioritization of many criteria. Fleet managers, contractors, and technical companies search for maximum equipment profitability during the economic life of a machine. Decisions on when to replace a piece of equipment are characterized by many uncertain factors that are difficult to quantify. A literature review and a scientometric analysis are conducted, revealing a gap in the global research, concerning the hierarchy of the criteria in decision making, when coming to procure a CE. The purpose of this article is to address that void in the extant literature by proposing a holistic equipment procurement decision model. A scientometric analysis of the last 25 years is performed to investigate the use of analytical hierarchy process (AHP) in the thematic area. A modified decision model based on the AHP is developed to prioritize factors that determine decisions on equipment procurements. Unstructured interviews with academia, experts, original equipment manufacturers, and practitioners in the field are conducted in conjunction with an extensive literature review to determine the critical “soft” and “cost” factors incorporated in the model. It seems that this is the first integrated attempt to prioritize the “key” factors that determine decisions of equipment procurement.

Renewable energy solutions based on artificial intelligence for farms in the state of Minas Gerais, Brazil: Analysis and proposition

Rural areas have great renewable energy potential. With an introduction to sustainable development goals, the smart farm concept presents a novel idea for providing energy in rural areas using artificial intelligence and renewable energy management. We proposed the following topics in this research: (i) methodologies for sizing generation systems by integer linear programming, (ii) use of analytic hierarchy process (AHP) to select the alternative source by financial, environmental, social, and physical criteria, and (iii) training of an artificial neural network (ANN) for process optimization based on the agroeconomic profile of farms. We applied the proposed generic methodology to farms in São Francisco do Glória, Brazil. The biomass, solar, and wind systems were indicated by AHP for implementation in 62.16, 15.32, and 22.52% of farms, respectively. The best configuration of ANN presented a maximum precision of 81.80 ± 3.36%. If the systems were to be implemented, 1.975 GWh yr−1 would be generated, 435.23 tonnes of CO2 would no longer be emitted per year, and a CO2 credit of 366.62 tonnes yr−1 would be injected into the national electric system. Public policies are necessary for this scenario to become a reality in Brazil, such as research incentives and market development.

Impact of coal mining on land use dynamics and soil quality: Assessment of land degradation vulnerability through conjunctive use of analytical hierarchy process and geospatial techniques

AbstractCoal is the major source of energy in India, where 66% of the thermal power is generated from different grades of coal. The surging energy demand for domestic and industrial sectors has accelerated coal production through intensive coal mining from existing mines and there is exploration for potential areas across the Country. More than 80% of the coal excavated from open cast mining, which is a damaging form of mining that is often associated with undesirable land use changes, soil degradation, and deforestation and is responsible for other environmental degradation. The present study has been conducted in Manendragarh coal mining area located in northern Chhattisgarh, Central India using the analytical hierarchy process (AHP) and geospatial tools. LANDSAT‐TM and OLI satellite data from 1990 and 2020 were digitally analyzed applying a maximum likelihood supervised classification technique in ERDAS IMAGINE and Arc‐GIS platforms. Spatial analysis of satellite data revealed that the area under forest, agriculture‐fallow, and waterbodies fell by 14.5%, 12.9%, and 2.52%, respectively, due mainly to conversion into degraded land, while the mining area and built‐up areas were proportionally enhanced by 3.2% and 0.59% between 1990 and 2020. The intense mining resulted in deterioration of soil health, where the organic C, pH, and soil depth were considerably decreased in mined sites and degraded lands, compared to agricultural and forest areas. The major determinant biophysical, topographic, and soil factors were integrated in a GIS platform to derive a land degradation vulnerability index (LDVI), which identified five vulnerability classes. The salient findings of study provides the critical inputs for the policy makers/environmentalists in prioritization and decision‐making for implementing remedial measures for the eco‐restoration of mining degraded landscapes and also the improvement of ecology and environment along with sustainable coal mining.

Identifying and analyzing the barriers of Internet-of-Things in sustainable supply chain through newly proposed spherical fuzzy geometric mean

Many industrial firms have gained strategic benefits from the use of IoT in supply chain (SC) and operations, but still, several firms are reluctant in applying this technology in their firm. Therefore, this study is going to identify and analyze the most influential barriers faced by firms during the adoption of IoT in attaining sustainable SC. The novelty of the current research work is the use of Analytical Hierarchy Process (AHP) under spherical fuzzy set to assess those identified barriers which are linked with IoT implementation in the context of sustainable SC. Compared to previously developed extension of fuzzy sets such as Intuitionistic and Pythagorean fuzzy sets, Spherical fuzzy set uses three dimensional membership functions capable of handling more uncertainty and ambiguity of preference given by the decision makers. The barriers are analyzed by segregating them into four major categories i.e. economic, organisational, environmental, and technological barriers. In terms of computational complexity the proposed spherical fuzzy AHP is much simpler to the previously developed spherical fuzzy AHP, as it utilizes the newly proposed Spherical Fuzzy Geometric Mean to compute the final score of the barriers. It is found that economic factor is the most influential factor among organizational, environmental and technological barriers. Overall operational cost and financial constraints/insufficient budget are the two most influential factors or major cause which acts as a hurdle in implementing IoT in the context of sustainable SC. The analysis on the crucial barriers in the adoption of IoT in sustainable SC suggest that financial rewards and compensations should be provided to the firms who adopted green material and green devices in IoT technologies.
