The priorities of the main criteria for selecting sustainable suppliers are 1) economic aspect, comprising main criteria: price (36.1%), quality (23.3%), service (14.3%), and reliability (10.3%) 2) environment aspect: the main criteria consisted of pollution management (5.5%) and environmental management (4.2%) 3) social aspect: the main criteria were employment practices (3.4%) and stakeholder responsibility (2.9%). In addition, the priority analysis of the 24 comprehensive criteria found that the criterion with the priority weighting was product price (30.17%), followed by correct specification (16.54%) and payment terms (5.91%). Furthermore, the most weighted by the case study of the overall economic aspect (84%), environmental aspect (10%), and social aspect (6%) respectively. The criteria from this research make the selection of suppliers consistent with the business practices of sustainability and weighting can be applied to improve the evaluation of supplier selection more efficiently.
