Description

High-risk facilities (HRF) are subject to strict regulatory oversight, encompassing mandatory registration, periodic technical inspections, and systematic maintenance of technical documentation. In practice, the management of these processes is hindered by a range of organizational shortcomings: facility data are scattered across heterogeneous registers and files, there are no automated mechanisms for tracking inspection deadlines, and the document workflow between technical supervision bodies (TSB) and facility operators relies predominantly on paper-based and traditional communication channels. This paper presents the design and implementation of an intelligent information system (IIS) aimed at digitalizing and optimizing these processes. The applicable regulatory framework - the Law on Technical Requirements for Products and the relevant subordinate legislation and the identified practical challenges are examined. Based on interviews with representatives of TSBs and facility operators, system requirements were defined and a three-tier web architecture was proposed, implemented with React (presentation layer), Ruby on Rails (business logic), and PostgreSQL (data management), supplemented by Redis for session management and background job processing, and Active Storage for file handling. Access control is secured through JSON Web Tokens (JWT) and a role-based access control model (RBAC) with three levels - administrator, TSV and user. The system centralizes the electronic technical record of each HRF, automatically calculates and monitors periodic inspection deadlines, generates mandatory documents and application forms, and provides a traceable document workflow with version control. Achieved results are presented alongside identified limitations - the absence of a mobile client, lack of integration with external national registries, and no support for qualified electronic signatures and directions for future development of the system are outlined.
