Comprehensive Assessment of Second-Life Battery Energy Storage System Operation Performance Based on Analytic Hierarchy Process

Groundwater resources are essential for drinking water, irrigation, and the economy mainly in semiarid environments where rainfall is limited. Currently, unpredictable rainfall due to climate change and pollution on the Earth’s surface directly affects groundwater resources. In this area, most people depend on groundwater resources for irrigation and drinking purposes, and every summer, most of the area depends on groundwater in a semiarid environment. Hence, we selected two popular methods, the analytical hierarchy process (AHP) and multiple influence factor (MIF) methods, which can be applied to map groundwater potential zones. Nine thematic layers, such as land use and land cover (LULC), geomorphology, soil, drainage density, slope, lineament density, elevation, groundwater level, and geology maps, were selected for this study using remote sensing and geographic information system (GIS) techniques. These layers are integrated in ArcGIS 10.5 software with the help of the AHP and MIF methods. The map of the groundwater potential zones in the study area revealed four classes, i.e., poor, moderate, good, and very good, based on the AHP and MF methods. The groundwater potential zone area is 241.50 (ha) Poor, 285.64 (ha) moderate, 408.31 (ha) good, and 92.75 (ha) very good using the AHP method. Similarly, the MIF method revealed that the groundwater potential classes were divided into four classes: 351.29 (ha) poor, 511.18 (ha), moderate, 123.95 (ha) good, and 41.78 (ha) very good. The results were compared to determine which methods are best for planning water and land resource development in specific areas that have basaltic rock and drought conditions. Both groundwater potential zone maps were validated with water yield data. The receiver operating characteristic (ROC) curve and area under the curve (AUC) model results are found to be 0.80 (good) and 0.93 (excellent) using the MIF and AHP methods, respectively; hence, the AHP method is best for delineation of groundwater potential zone maps and groundwater resource planning. The present study’s framework and the results will be valuable for improving the efficiency of irrigation, conserving rainwater and maintaining the ecosystem in India.

With the rapid development of science and technology, new technology is starting to be used in various fields including education. Education has a very important progress in a nation, because it can optimize individual potential. The educational process in higher education has a big influence on a student's future. However, there are many students who experience difficulties in choosing a college major after graduating from vocational high school (SMK) or senior high school (SMA), because of the complexity in identifying the suitability between interests and study programs. Decision making is a problem that everyone faces, especially in choosing an appropriate college major. There are many factors to consider, and with many options available, the decision-making process can be difficult. To overcome this problem, this research aims to create a decision support system (DSS) using the AHP (Analytical Hierarchy Process) and TOPSIS (Technique For Order By Similarity To Ideal Solution) methods. The AHP method is used to solve complex problems by structuring a hierarchy of criteria and developing weights or priorities. However, when the AHP method is used with many criteria and alternatives, other methods are needed for more effective results. Therefore, a combined method of AHP and TOPSIS was chosen, where AHP focuses on pairwise comparison matrices and consistency analysis, while TOPSIS can measure relative performance and alternative decision making simply and efficiently. The results of research on decision support systems for selecting majors using the AHP and TOPSIS methods show that the application of the combined AHP-TOPSIS method can be used to determine the best alternative in selecting majors by comparing alternatives based on predetermined criteria. In addition, system testing results show that the system functions as expected and meets user needs. With a decision support system for selecting college majors implemented on the website, it can simplify the decision-making process for students and BK teachers in choosing college majors. The results of the calculation of the percentage of system feasibility in blackbox testing show a value of 95.71%, which indicates that this major selection decision support system website can be used.

In this study, it is aimed to examine the studies based on the AHP (Analytic Hierarchy Process) method in the field of education and to present the researcher's perspective on how to use the AHP method in the field of education. Within the scope of this aim, firstly the AHP method was introduced with a sample application and then the results were interpreted. The other aim of the research; studies which based on the AHP methods in the field of education in the last five years have been examined through content analysis. AHP; is one of the “Multiple Criteria Decision Making (MCDC)” methods that can determine the priority or weights among the criteria and alternatives based on comparative judgments. The content analysis conducted within the scope of the research was carried out in the context of eight criteria determined by the researchers. According to the results of the analysis; the AHP method has shown an increasing tendency compared to the years, and usually is used for determining and prioritizing teaching priorities. Especially in Asia Pacific countries, the AHP method is used much more intensive. Another result is that the AHP method is used to make group decisions rather than individual decisions. It has been seen that the research has been done especially with undergraduate students. In addition to these, there are lots of studies with academicians and experts.

Scheduling is one of the important things in teaching and learning process. The Analytical Hierarchy Process (AHP) method is a system analysis method that can be used to connect unstructured situation into a spesific part that used to make an effective decisions. The application of AHP based on the decomposition of objectives, evaluates values through pairwise comparisons in stages and able to choose the best alternative from some alternatives. The purpose of this study is to prove whether the AHP method can be used to determine scoring for the election of lecturer schedules and to knowing the result of AHP’s scoring The data in this study are: criteria of the subjects, lecturers, SKS, lecturer status, space, time to determine the score and alternative, namely in the form of even semester teachers. As for producing departmental recommendations, input is needed in the form of score resulting from the AHP calculation and calculating the space that shows the floor, day and course. This study uses comparative data and the same alternative from previous studies,that is scheduling data for the Even Semester of Mechanical Engineering Study Department that certain on scheduling for regular lectures. The final results of this study include several names that can be used for scheduling first. Judging from the previous research using the DS / AHP method, 17 lecturers got the order from 29 lecturers, but in this study, the whole can be sorted.

There is a need to increase the effectiveness and efficiency with which the operational fund budget is managed at RSUD Brigjend H. Hasan Basry Kandangan. Declining revenue projections and limited resources mean that hospitals must determine budget priorities in an objective and measurable way. This research aims to analyse the application of the Analytical Hierarchy Process (AHP) method to determine operational fund budget priorities, providing recommendations to support more effective decision-making in a hospital environment. A qualitative approach was used, involving data collection through interviews and documentation, and analysis using the AHP method with the assistance of Expert Choice 11 software to compare criteria and service alternatives. The results showed that the main criteria for determining budget priorities are potential income, market demand, operational costs and limited resources. The analysis prioritised home care services due to their high revenue potential and market demand. The application of AHP has also been proven to increase the efficiency, transparency and accountability of budget decision-making processes. This study concludes that the AHP method can be an effective tool for BLUD Hospital's operational budget prioritisation process. It is recommended that the method be integrated into all work units and supported by training for optimal application.

Beef is a livestock product that has economic value. The high demand for meat requires farmers to cultivate cows by supplying cattle to meet consumer needs. In terms of selecting beef cattle seeds, independent breeders still do traditionally. During this time farmers still use the trial and error method in choosing the best type of cow even just concerned with the price factor. This will obviously affect the quality of cattle which results in expensive maintenance costs, less than optimal production yields and even death of cows. The purpose of this study was to conduct a study of the application of technology in the selection of the best beef cattle to increase livestock yield, especially for local independent breeders. The technology used is a combination of the Analytical Hierarchy Process (AHP) method and the Multy Factor Evaluation Process (MFEP) Method. Through a combination of methods, researchers analyzed each criterion and alternative related to the selection of the best beef cattle. AHP method was chosen because it has the ability to analyze more consistent criteria. While the selection of the MFEP method is due to having the ability to analyze alternatives based on existing criteria in a simple and accurate way. The results of the AHP and MFEP analysis method are AHP analysis to assist in determining the priority factors of beef cattle seedlings and applied to the MFEP method which produces the highest alternative A6 with a value of 0.508. This research is expected to become a new foundation for farmers in knowing the criteria and alternatives in determining the best type of beef cattle.

GIS-based landslide susceptibility mapping using analytic hierarchy process and artificial neural network in Jeju (Korea)

The operation situation evaluation is the basis of situation awareness in active distribution network (ADN). In order to reflect the satisfaction of distribution system operation state, a comprehensive method for operation situation evaluation in ADN based on expert experience is proposed. The evaluation system considers the safety, economics and environment of the ADN. A piecewise linear function which can reflect the change rule of the evaluation indicators is used to normalize the indicators, it considers the relationship between the cost and satisfaction of the indicators in different intervals. The reference values of the indicators are determined by the expert experience. Analytic hierarchy process is used to determine the weight of each indices. Finally, an actual example is used to test the proposed method and the influence of renewable energy and network topology on the operation situation of ADN are analyzed.

Career development is one of the benchmarks for an employee in his career, where performance appraisal is the dominant factor in employee career development at PT. X. In determining the performance appraisal, there are subjective things that become the reference for a superior in giving more assessments to employees. In this study, the indicators that become the reference for a superior in giving more assessments to subordinates can be used as a reference for an employee in improving his performance. The selected indicators are tested in pairwise comparisons and then processed using the Analytical Hierarchy Process (AHP) method to find out the priority weight of the indicators used by superiors in giving more assessments to their subordinates. From the results of calculations using the AHP method, the priority order of each component can be obtained, which can then be determined by the highest weight of the indicators used. From the results of calculations using the AHP method, the following priority order can be obtained: Loyalty priority is 0.57, then Attitude is 0.17, then Active is 0.11, Discipline is 0.08 and Honesty is 0.07. Thus, the factors that require attention and improvement in the performance of an employee are related to loyalty with the highest priority weight gain. Keywords: Attitude, Honesty, Loyalty, Discipline and Activeness, Career Development, Performance Appraisal, Analytical Hierarchy Process.

Every year, some social assistance is distributed by the Ministry of Social Affairs to each village/Nagari aimed at low-income families. The problem of poverty data almost occurs in all village/Nagari governments. In Koto Baru Simalanggang, several issues arose, including social assistance being mistargeted, poverty assessment being very complex, no system helped in DTKS, and no empowerment/system was carried out in reducing social problems; thus, all were put into DTKS without being able to see the details. Thus far, for the examination of the data of the proposer of assistance, the Nagari government still uses manual methods; therefore, it takes a long time and is subjective to the settlement of low-income families. Posdaya Bundo Saiyo is assisting in Koto Baru Simalanggang for the poor beneficiaries. There needs to be a decision support system to determine people with low incomes in this Nagari; using the method to determine people with low incomes is more objective. The results of this study are in the form of a decision support system for the determination of people with low incomes, which is used as a reference for the Bundo Saiyo Posdaya to make recommendations for the determination of people with low incomes to the Mayor of Koto Baru Simalanggang using Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) and Analytical Hierarchy Process (AHP) methods. Based on the comparisons made in this research, the AHP and TOPSIS methods have the same ranking results

Choosing the right office facility vendor is a strategic factor in supporting smooth operations, cost efficiency, and compliance with safety and environmental standards.
