Abstract: The tourism industry encounters many complicated decision-making problems on supplier selection. Companies have to make a very comprehensive collaboration with many suppliers to give quality hospitality services. However, selecting appropriate suppliers is not easy, as many conflicting criteria affect the evaluation processes. Furthermore, complexities are ever-increased depending on the number of alternatives and criteria. This paper proposes a novel multi-criteria decision-making (MCDM) framework to solve these decision-making problems encountered in the tourism and hospitality industries. The proposed framework consists of two MCDM techniques. First, the Simple Additive Weighting (SAW) method was applied to convert the subjective evaluations of some criteria to the crisp values. Second, the simultaneous evaluation of criteria and alternatives (SECA) technique was implemented to identify the criteria weights and determine the preference ratings of the decision alternatives. In this perspective, the proposed methodological framework was applied to evaluate dairy products suppliers in Turkey. The identified evaluation criteria are price, reliability, delivery performance, product quality, payment ease, packaging quality, warranty period, product variety, production capacity, and financial situation. According to the analysis results, it has been observed that the criterion of financial situation is the most influential factor, and the A4 option is the best alternatives.
