The value of the first DM is multiplied by the value of the second DM, then, the value of the first DM is multiplied by the value of the third DM, and so on, until the value of the first DM is multiplied by all DM values. This is performed for each DM and the values are added. Then, this is multiplied by the value k(k\(-\)1), which is the value 0.05 (1/20). Finally, the root value is calculated and the Bonferroni mean operator values are formed. After that, the Bonferroni mean operator (BMO) values are ranked and the steps of the SWARA method are calculated. In order to apply the SWARA method, it is necessary to rank the criteria. Thus, the first criterion is ranked C2, followed by criteria C1 and C10 up to criterion C8, which is the lowest ranked criterion. Then, the relative importance values of the criteria are calculated. The value of one (1) is given for the best-ranked criterion, which is criterion C2. Then, this value is calculated for the next criterion, namely, C1, in such a way that the value of the criterion for which the relative importance is calculated is subtracted from the BMO value of the better-ranked criterion, and the value of one (1) is added. In the example of this criterion, the calculation procedure is as follows (Equation (14)):  
\[k_{\text{C1}}=0.886-0.872+1=1.014\]  
Respecting this principle, the relative importance of all criteria is calculated. Then, the relative \(q_{j}\) value is calculated. The highest ranked criterion (C2) is overwritten by the \(k_{j}\) value and then, the relative \(q_{j}\) value is calculated, by taking the \(q_{j}\) value of the better-ranked \begin{table}

Table 6: Crisp decision matrix and Bonferroni mean operator values. criterion and dividing it by its \(k_{j}\) value. In the example of criterion C1, this calculation is performed as follows (Equation (15)):  
\[q_{j}=\frac{1.000}{1.014}=0.986\]  
In the next step, the values \(q_{j}\) are added for all criteria and the weight of the criteria is calculated. This procedure is performed in such a way that the individual \(q_{j}\) values of the criterion are divided by the total value \(q_{j}\) criterion. The weight calculation procedure for the example of criterion C1 is as follows (Equation (16)):  
\[w_{\text{C1}}=\frac{0.986}{8.712}=0.113\]  
Determining the weights in this way and using the steps of the SWARA method showed that based on the DM, the most important criterion is C2--Reliability and Quality, followed by C1--Innovation and C10--Sustainability (Table 7). The least important criterion based on these DM ratings is C8--Education and Training. When all the weighted criteria are considered, it can be concluded that there is no significant deviation, so all criteria have significant importance in selecting a supplier. After the weights of the criteria have been calculated, the suppliers are ranked. The first step in this process is to evaluate the selected suppliers using the criteria. Each DM provides a score in the form of linguistic terms (Table 8). Then, the linguistic terms are converted into intuitionistic values in the same way as for the criteria. Then, a summary intuitionistic decision matrix is formed using BMO. Using this operator, the average intuitionistic value is calculated.
