This fact is highlighted in the oil and gas industry. To choose the best suppliers for the O&G industry, this research presents the three multi-criteria decision-making (MCDM) techniques: analytic hierarchy process (AHP), stepwise weight assessment ratio analysis (SWARA), and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). In the first phase, we delved into the literature of O&G industry to extract the most important and significant factors affecting supplier selection decisions. Then, the three MCDM methodologies are used to optimise supplier selection decisions through conducting a real case study in Oman. The study concludes by proposing some efficient managerial implications through the achieved results. Inderscience Publishers - linking academia, business and industry through research
