“…It also aims to find groups in the data, with the number of groups represented by the variable K (Cerqueti & Ficcadenti, 2022). According to Liao et al (2022), the variable K is the desired number of clusters. This Algorithm Cluster divides the data into several groups and receives input in the form of data without class labels.…”

Multiple disruptions in health sectors and geopolitics has been alarming food security worldwide. This study provides insights by assessing the determinants of food security in Indonesia and creating a map of the country's most food insecure areas as a basis of developing anticipating strategies. This study is quantitative in nature using secondary data from the Statistics Indonesia. To estimate the model, we used Non-Parametric Splines Regression and Clustering Analysis. The results show that food security in Indonesia is greatly impacted by rice production, population density, purchasing power index, food expenditures, and harvested area. Additionally, most of the provinces in Indonesia has a medium to high food security level. The results showed the need for integrating Indonesian food chain policies such as land, water, and fertilizer availability. In addition, the Indonesian Bureau of Logistics must take measures to preserve the availability and distribution of staple foods.

“…Depending on the implementation of different consensus rules, CRP models can be divided into two types, i.e., identification-direction consensus rules and optimization-based CRP models [30]. Despite the classical consensus model in which the facilitator assumes control of the CRP and provides advice to DMs [31,32], both facilitator and feedback mechanisms are obsolete in environments involving hundreds or thousands of DMs because they are too time-consuming and not feasible in practice. Therefore, in the context of LSGDM, the classical consensus model as an iterative discussion process should be replaced by automated algorithms that do not involve discussion rounds, moderators, or approval of DMs to change their opinions [10].…”

Civic participation is of great significance to urban management decision-making. In order to facilitate citizens to participate in city management decision-making, this paper proposes a large-scale group decision-making (LSGDM) method based on multi-granular probabilistic linguistic preference relations (MG-PLPRs). First, each decision maker selects a language terms set from the multi-granularity language terms set to represent individual preference relations and the MG-PLPRs are obtained by statistical calculation to represent sub-group’s preferences information. Then, an optimization model based on the expected consistency of PLPR and consensus measure of groups is established to achieving consensus reaching processes, which can ensure satisfactory individual consistency and group consensus. Finally, the validity and applicability of the proposed method is verified by a case of a city "shared garden" site selection with the participation of citizens.

“…Currently, the research on MADM in complex environments and fuzzy information backgrounds has attracted great attention from more and more scholars at home and abroad [8][9][10][11]. However, due to the complex reality environment and the increase of uncertainty [12][13][14][15], as well as the subjective randomness of people's thinking, the traditional MADM method has certain limitations [16][17][18][19]. In order to better describe uncertain information, Zadeh [20] brought forward the theory of fuzzy sets (FSs) in 1965, which mainly represents information through the membership function of things.…”

In the classroom teaching of Chinese international education (CIE), teachers will face different types of problems. Teachers should focus on each teaching link, identify key and difficult points, teach students in line with their aptitude, and emphasize communication with students to improve the classroom teaching quality in CIE. The classroom teaching quality evaluation of CIE in higher-education institutions is regarded as multiple-attribute decision-making (MADM). Recently, the EDAS and CRITIC model was employed to put forward the MADM. The double-valued neutrosophic sets (DVNSs) are employed as the optimal decision tool for expressing the uncertain data during the classroom teaching quality evaluation of CIE in higher-education institutions. In this paper, EDAS is founded for MADM under DVNSs. Then, the double-valued neutrosophic number EDAS (DVNN-EDAS) model is constructed for MADM. Finally, a numerical example for classroom teaching quality evaluation of CIE is employed to verify the DVNN-EDAS model. The main decision contribution of this study is that (1) the novel MADM technique is established in line with EDAS and CRITIC under DVNSs. (2) The objective weights are constructed through CRITIC. (3) A numerical example for classroom teaching quality evaluation of CIE in higher-education institutions in line with the DVNN-EDAS is constructed.
