Some Aggregation Operators Based on Dombi t-norm (TN) and t-co-norm (TCN) Operations: Applications in Economic Corridor Prospective

Abstract

The role of transportation in international trade cannot be overlooked; hence, the need for regular upgrades of roads and marketplaces. The Karakorum Highway (KKH), a vital part of the China–Pakistan economic corridor that connects China with Arabian waters, has not received significant attention from the National Highway Authority (NHA) due to uncertainties in many regions. To address this issue, the study employs Dombi operations using Polytopic fuzzy sets to explore uncertainty in decision-making. The Dombi t-norm and t-co-norm can capture inconsistencies, making it an effective tool in the decision-making process. The study applies the Polytopic fuzzy Dombi-weighted averaging (PF-DWA) operator, the Polytopic fuzzy Dombi-ordered weighted averaging (PF-DOWA) operator, and the Polytopic fuzzy Dombi hybrid-weighted averaging (PF-DHWA) operator to demonstrate how the model can help the NHA open bidding for interested companies to repair damaged areas, bridges, and side barriers affected by floods. The study reveals that infrastructure is essential for the development of any country, and the most suitable choice for reconstruction can be made using the proposed methods.
