Application of the mivar approach in creation of decision support systems for public services

Currently, there is an active digitalization of the processes of providing public services and performing public functions by state authorities. In the field of public services, the task of their proactive provision has been set, as a result of which there is a need to develop decision-making support systems for providing services to the population in a proactive form and their information support. Such systems should be able to adapt to changes in legislation in the provision of public services, and in addition have such a logical inference mechanism that could determine the public services that an applicant is entitled to based on limited information about him. The purpose of the study was to investigate the possibility of using the mivar approach in creating such decision support systems. The essence of the mivar approach as a mathematical tool for the development of artificial intelligence systems created by combining the production approach and "Petri nets" is characterized. The model and methods of the mivar approach are considered, the analysis of models for representing data structures, as well as methods for finding the route of inference on the network of rules, is carried out. A technological and technical description of the decision support system based on the mivar approach is presented. The stages of building a logical network of hyper-rules with multiactivators created using expert systems are proposed, and its implementation is shown on the example of the provision of public services.
