This paper discusses the analytic hierarchy process method for decision-making from multi-criteria and is used to solve complex problems in vendor selection. The identified criteria were used in conjunction with the theoretical concepts from AHP only and the "Expert Choice" computerized software program based on AHP in carrying out the development of the vendor selection model. This study aims to use this approach to be able to build a vendor selection system using the priority weight values of the criteria for quality, price, warranty, and delivery time. The researcher used a questionnaire to several users from the fleet and operations division. From this research, it is known that the warranty is the highest weighting criterion among the existing criteria with a value of 0.300 of all criteria, followed by the criteria for quality of goods with a value of 0.265 and the criteria for delivery time with a value of 0.242, and the price criteria with a value of 0.194. From this research, it is also known that PT KMI was chosen as the top supplier because it has the highest value weight.
