“…Nevertheless, it is worth identifying how obtaining the rankings of MCDA methods vary from one another. Three methods were selected to solve the problem of evaluating material suppliers in the metallurgical industry: COMET, SPOTIS and TOPSIS [2,5,66,67]. It was also decided to use criterion weighting methods to check their performance on the results obtained.…”

Decision-making processes increasingly use models based on various methods to ensure professional analysis and evaluation of the considered alternatives. However, the abundance of these methods makes it difficult to choose the proper method to solve a given problem. Also, it is worth noting whether different results can be obtained using different methods within a single decision problem. In this paper, we used three selected Multi-Criteria Decision Analysis (MCDA) methods called COMET, TOPSIS, and SPOTIS in order to examine how the obtained rankings vary. The selection of material suppliers was taken into consideration. The equal weights, entropy and standard deviation methods were used to determine the weights for criteria. Final preferences values were then compared with the WS similarity coefficient and weighted Spearman correlation coefficient to check the similarity of the received rankings. It was noticed that in the given problem, all of the methods provide highly correlated results, and the obtained positional rankings are not significantly different. However, practical conclusions indicate the need to look for improved solutions in the correct and accurate assessment of suppliers in a given period.

Bantuan pemberian sembako terhadap anggota keluarga angkat masih saja sering menimbulkan kesalahan dalam memberikan jumlah sembako yang diberikan, maka dalam penelitian ini dilakukan agar dapat menentukan jumlah sembako yang diberikan dengan menggunakan prioritas. Data yang digunakan dalam menentukan prioritas didapatkan dari hasil wawancara dengan narasumber. Dalam menentukan prioritas bantuan keluarga angkat di perlukan metode Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). Namun metode TOPSIS belum memberikan hasil yang akurat, maka dalam penelitian ini akan membandingkan metode TOPSIS dengan Characteristic Object’s Method (COMET). Hasil kedua metode ini dibandingkan dengan menggunakan persamaan koefisien. Akurasi dengan menggunakan Spearman Coefficient sebesar 98,7879%, Weight Spearman Coefficient 99,449%, WS Coefficient 100%.

“…Recently, MCDA methods have been widely used in different fields and disciplines [20]. TOPSIS is an acronym that stands for technique for order preference by similarity to an ideal solution and is widely use in solving practical problems [20,21,25,26]. This method has a solid mathematical foundation and a rigorous calculation process.…”

The evaluation of scale management suitability provides a comprehensive assessment of the various factors driving farmland management conditions. This research objectively evaluated the conditions for scale management suitability by applying the entropy-TOPSIS method with the aim of effectively balancing the space for agricultural production, the development of towns, and ecological protection. First, to ensure a balance between agricultural production, urban development, and ecological protection, 13 indexes were selected to represent the following three areas: natural factors, socioeconomic factors, and characteristics of cultivated land factors. The original matrix was standardized to evaluate the suitability of natural resources, the social economy, and cultivated land conditions, and a comprehensive suitability evaluation of scale management in the Jiangjin District of Chongqing was conducted. The research results divide the study area into four regions based on the level of scale management suitability. Examining the spatial distribution, the level of scale management suitability decreased gradually from north to south, regions at the high and middle levels of scale management suitability were concentrated in the northern area beside the Yangtze river, and the regions at a low level were concentrated in the southern mountain area. This research can provide a reference for the rational utilization of land resources and land use policymaking.
