The efficiency of the purchasing process co-decides on the success of the production organization. One of the basic tools for quality purchasing management is the selection and evaluation of suppliers. We can use a wide range of tools to evaluate suppliers, and this evaluation can be based on a large and diverse set of criteria. In the case of evaluating many potential suppliers according to a number of criteria, it is not possible to rely solely on the intuitive nature of the evaluation. Therefore, managerial tools based on the mathematical principles of multi-criteria decision-making have been increasingly important. The article deals with the analysis of the realized research focused on the use of mathematical methods in the evaluation of suppliers in an industrial enterprise. This article aims to analyse the possibility to use tools based on determining weighted order when evaluating suppliers. Data obtained from the research in a selected industrial enterprise in the Czech Republic was used for evaluation.the final values of all the criteria is a crucial parameter for the evaluation. Based on this value, suppliers are then ranked in descending order. The formula (2) and (3) were used to calculate the values. The last row of Table 4 lists the final ranking of suppliers.
