The methods of formalization of verbal indicators-concepts in the process of support of managerial decision - making in the evaluation of experts as the existing risks and identified opportunities for improvement with the use of score scales are considered. The purpose of the work is to improve the process of input control of raw materials in the testing laboratory. An example of calculating the parameters of the membership functions of triangular fuzzy numbers in the process of supporting management decision-making is given. According to the information about effectiveness andefficiencyperformance indicators of improvement projects presented in the applications of heads of departments, the decision-maker has the opportunity to select the optimal management solution that provides the highest economic efficiency due to the implementation of improvement projects.The graphical representation of the membership function for the fuzzy number "priority number of improvement opportunities" allowed the decision maker to approve the plan proposed by the team of experts for the implementation of the project to improve the testing of purchased raw materials "white spirit". The work carried out confirmed the correctness of the management decision. After the implementation of the improvement project, the costs of the “white spirit” raw material input testing business process decreased by about 5 %, while the volume of work performed increased by 1 %.
