Information Technologies and Computer Engineering

The paper develops an information technology based on the implementation, conduct and processing of expert assessments and collective surveys. The main stages and objectives of the study are described, the stages of prototyping the application at the conceptual and design levels are presented. The choice of an architectural template for designing a software product is substantiated. The distribution of roles between users is carried out by studying the needs of the target audience of the application and using UML modelling tools. The study shows a step-by-step development of the main algorithms for expert evaluation and collective survey. The issue of experts' choice of the most attractive method for evaluating alternatives is thoroughly studied, which is implemented through step-by-step development and addition of methods to the application. The database created in the course of the work meets all modern database standards and has increased security due to its hosting. The procedure for designing and testing individual modules for visualising the results of calculations is described, and new qualitative scales for non-critical and critical evaluation of alternatives are developed. The application has been tested with a sufficient number of users and its effectiveness and innovation have been confirmed. The average usability of the application is calculated using a modern integrated evaluation metric. The created information technology can be used as an effective tool for conducting large-scale assessments on professionally important issues at any level
