**4. Results**

The results obtained in both the cases are summarized as follows in **Table 5**, and the relative closeness scores under both the cases are presented in **Figures 1** and **2**.

Based on the rankings of the alternatives obtained under both the cases, it clearly gives the preferential ranking of the alternatives. In almost all the cases, nonthermal

processing technology acquires the first preference and chemical processing technology acquires the last preference. This ranking is validated under both the cases when various normalization techniques are used. The aggregate decision matrix obtained by using the plithogenic aggregate operators adds to the consistency of the proposed model. The ranking results differ only in both the cases under the normalization technique of the linear scale transformation sum method.
