Abstract:
To comply with the environmental standards set by the United Nations, Negative Emission Technologies or NETs are looking to be an important technological acquisition in the coming decade, there is potential and necessity in acquiring the technology. Considering that the NETs is a new and unestablished technology, there is uncertainty involved in the planning and deciding the NET to acquire and install. With this in mind, the development and acquisition of NETs becomes a Multi Criteria Decision Making (MDCM) problem with considerable uncertainty. Interval VIKOR is an extension of the traditional VIKOR method developed by Opricovic which specializes in solving MCDM with opposing criteria. The aim of this study is to assess the viability of the application of Interval VIKOR to planning NETs assessing rank creation. In this paper, data from case studies that tackle NETs were synthesized and normalized to be used in the VIKOR algorithm. The NET alternatives that were considered in this paper are: BECCS, AR, SCS, BA, DAC, and EW. On the other hand, the criteria considered were sequestration potential, water requirement, energy requirement, specific cost, and threshold limit. The specific weights adapted from a similar paper by Tan et al., 2020 and the α and v values were decided to be 1 and 0.5, respectively. Using these, the Interval VIKOR algorithm generated a rank that produced DAC as the most optimal alternative which complies with the stability criteria. Additionally, sensitivity analysis was performed to assess the dynamics of changing both α and v values which generated graphs and figures to show the best alternative based on the context of the decision maker. Through the Interval VIKOR, a ranking with conflicting criteria may be generated using data from existing case studies which can be adjusted to fit the requirements set by the decision maker.
