“…The contents of the respondents to be entered into the matrices are formed by means of pairs called pairwise matrices. The solution technique is carried out to obtain the eigenvector value in two ways, namely using the expert choice application (Erdogan et al, 2017) and with the mathematical algebra matrices method, with the expert choice application through the input process as usual (Pagliuca & Scarpato, 2014) and can be generated directly to get the optimal eigenvector value , but by means of the methematic algebra matrices you have to through repeated calculations to obtain the optimal eigenvector value and a consistency test must be carried out through the amount of the consistency ratio (CR) which must be less than 10 percent (Zhao & Deng, 2022), this means that a temporary decision can be accepted.…”

The progress of smartphone technology is now very rapid, supported by many renewable features, even many users are competing to get the latest products without regard to the costs that have been incurred. The problem that arises is that it is increasingly difficult to select technology-based products with many criteria. The purpose of writing this paper is to provide the best solution for selecting technology-based products with multi-criteria to suit user needs by taking into account the costs incurred effectively and the use of contradictory multi-criteria applications. The presence of technology products always has many criteria that make it more difficult for users to choose products as the right choice according to their needs, thus the right method is needed as a solution to obtain technology-based products such as smartphones. The Analytic Hierarchy Process (AHP) method is used for the evaluation and selection process. This AHP method will collaborate with the ELECTRE and PROMETHEE methods as a comparison solution for smartphone product selection. The resulting comparison will be an applied model for smartphone selection that produces the best decision-making support according to user needs. The results of the collaborative implementation process of the ELECTRE and PROMETHEE methods provide a decision on the rating system. The collaborative application of the AHP method to the ELECTRE and PROMETHEE methods provides optimal decision support for the selection process, so that this can be used as a comparison material in making decisions regarding the selection of smartphones as technology-based products.

“…Despite the criticism, Saaty's original proposed Consistency Index (CI) is actively used in significant decision-making processes, as follows: quantum computing challenges in the software industry [37]; analysis of project benefits of solar energy collection and irrigation systems (supported by funds for the Sichuan Vanadium and Titanium Materials Engineering Technology Research Centre Project) [38]; for contractor assessment during project life cycles (supported by Al-Mansour Contracting Company for Contracts, the Ministry of Housing and Construction, Iraq, and the University of Baghdad) [39]; for access point selection in hybrid LiFi/WiFi networks [40]; for reinforcing doctor-patient communication (supported by the Ministry of Education of the Republic of Korea and the National Research Foundation of Korea) [41]; to evaluate sustainable healthcare systems [42]; for risk assessment of oil and gas pipelines hot work [43]; the evaluation of the emergency management capacity of resilient communities (funded by the Humanities and Social Sciences Project of the Ministry of Education) [44]; for the selection of the type of concrete and the method of its maintenance in dry, hot climate conditions (supported by the Poznan University of Technology-Polish Academy of Science) [45]; in changing the damming level of a small hydropower plant (co-financed within the framework of the Ministry of Science and Higher Education programme as "Regional Initiative Excellence") [46]; for the optimal design of ceramic-based hip implant composites [47]. In a review article covering usage from 1977 to 2022, the highest percentage of publications came from China, India, and Iran.…”

A precise evaluation of the actual situation is a significant aspect of making a correct and informed decision. Due to the bounded accuracy and elements of uncertainty in the data itself, a point estimate may be less adjusted and rough than an estimate based on fuzzy set theory. The stability of the Fuzzy AHP Arithmetic mean, Geometric mean, Extent analysis, and Lambda Max methods, widely used in practice, is verified. Three stages of verification are considered, investigating the impact of the following: (a) the scale applied; (b) methods of aggregation of the AHP matrices into the FAHP matrix; and (c) methods of combining several FAHP judgments. Slight changes in experts’ estimates are programmatically simulated tens of thousands of times to track changes in ranking and deviations of results from the initial estimate. This continues the study of FAHP’s stability due to the ambiguous results of such verification by the method of extent analysis. As a result of a comparative analysis of the listed evaluation methods, their specific features and advantages are identified.

“…The existing weighting methods can be classified into two categories: subjective-based methods and objectivebased methods. The former calculates indicator weights according to the subjective will of experts, such as the Analytic Hierarchy Process (AHP) [43,44], the Delphi Method [45], etc. ; the latter determines weights based only on the indicator values, not subjective judgments, and includes the Entropy Method [46], the CRITIC Method [47], the Variance Coefficient Method [48], Principle Component Analysis (PCA) [49], etc.…”

Irrigation districts are a pivotal infrastructure of agricultural water conservancy engineering. Implementing modernization will be the main task of large-scale irrigation districts for a considerable amount of time in the future. In this study, four typical large-scale irrigation districts in North China were investigated: the Renmin Shengliqu, Weishan, Shijin, and Zuncun irrigation districts. The concept of a modern irrigation district was deconstructed to establish an evaluation index system which includes four second-level indicators, twelve third-level indicators, and thirty fourth-level indicators. A hybrid approach based on AHP and OWA was used to quantify indicator weights used in group decision making. TOPSIS was introduced to measure the modernization level of the four irrigation districts. An obstacle factor diagnosis model was applied to search for key obstacle factors that will affect the modernization and improvement of the irrigation districts. The results showed that (1) the modernization levels of the Renmin Shengliqu, Weishan, Shijin, and Zuncun irrigation districts in 2020 and 2025 were 0.3916 and 0.5755, 0.3748 and 0.5396, 0.4493 and 0.6012, and 0.2343 and 0.6166, respectively. The evaluation results indicate that the four irrigation districts are still in the beginning phase (or even preparation phase) of the modernization process. (2) Eight indicators were identified as the main common obstacle factors for the four evaluated irrigation districts, including the irrigation water-use efficiency factor, the coverage proportion of information technology, the proportion of efficient water conservation irrigation areas, and so on. (3) There are two effective methods to enhance the modernization level of the four irrigation districts: improving water resource utilization efficiency and strengthening the management system with an emphasis on informatization. The present study can enrich the theoretical evaluation of irrigation districts and provide a scientific basis for the modernized construction and management of irrigation districts in China.
