МЕТОДИКА ЕКОНОМІЧНОЇ ОЦІНКИ ЗАГАЛЬНОЇ СУКУПНОЇ КОРИСНОСТІ ПРОДУКЦІЇ, ПОСЛУГИ, ПРОЦЕСУ

When assessing the quality of products, services, and processes, the consumer is guided mainly by his subjective perception, which is not always objective, economically justified, and expedient. Purpose. To propose an objective methodology for determining the optimal price-benefit ratio for comparing economically rational estimates of the total aggregate utility of a product, service, or process. Methodology. Expert evaluation methodology, methods for determining weighting coefficients of product property indicators, use of Harrington's desirability function in the evaluation process. Results. The cost of one conditional unit of utility of a product, service or process is determined. The ratio of the price of a product, service or process to their total aggregate utility gives us an optimally more profitable option, in which the cost of a conditional unit of utility is minimal. Scientific novelty. The proposed methodology is an attempt to combine the two most important alternative directions of economically rational assessment: cardinalist (quantitative) and ordinalist (ordinal) in order to determine the economically optimal total aggregate utility of a product, service or process from the consumer's point of view. Practical significance. The use of the proposed methodology will allow to automate the process of objective evaluation of tender offers and eliminate the subjective component when making a procurement decision, eliminate discrimination of applications and achieve transparency of the entire tender process, systematically eradicate and prevent corruption in the field of public procurement and achieve simplicity and convenience of applying tender procedures.
