Abstract: Abstract The greater concern toward depleting oil resources and environmental restrictions has attracted a great interest of the scientific community to employ vegetable oils in high-temperature applications. Vegetable oils are environmentally friendly, renewable, non-hazardous, abundant and less flammable in comparison with their mineral counterparts. Moreover, the vegetable oils possess comparable thermophysical properties to that of other thermal oils used in solar applications. Owing to the associated advantages, researchers have studied the applicability of numerous vegetable oils for solar applications. However, a major challenge lies into adjudge the performance of given vegetable oil with respect to the other vegetable oil for a given solar application as heat transfer fluids with due consideration to economic as well as time aspect during the early phases of project implementation. The present work, therefore, proposes to address the aforementioned challenge of performance evaluation of vegetable oils employed in solar power plants through an interval-valued fuzzy information decision-making tool integrated with TOmada de Decisao Interativa Multicriterio (TODIM) method. A comparative analysis and sensitivity analysis have been carried out to validate the obtained ranking results. The proposed decision-making methodology not only relives the decision-making process with unreasonable data but also takes into consideration the inevitable psychological behavior of the experts toward risk. Therefore, the proposed decision-making framework can be used with confidence in making decisions within a sustainable technology framework.
