This article develops a logical-structural model of a computer-oriented procedure for normal operation and elimination of violations for the support system for NPP operational personnel. The purpose of this study is to create a model of a computer-oriented procedure, the data structures of which will comply with technological regulations and instructions for NPP operational personnel and contain information about the relationship between states and steps of procedures. The object of the study is the process of forming computer-oriented procedures for controlling a NPP power unit. The subject of the study is logical-structural models of computer-oriented procedures and methods for identifying states and steps of procedure execution based on production rules. The following tasks were solved in this study: the data structure of the computer-oriented procedure model was developed, which complies with current regulations and instructions; a logical-structural model of a computer-oriented procedure was created, which will be used to create support systems for NPP operational personnel; A method for identifying the conditions for entering the procedure and performing its steps has been developed. The model is designed to solve the problem of maintaining relevance, early identification of the states of the power unit and its equipment, ensuring the possibility of obtaining information about the state of technological parameters with the required level of reliability and accuracy. The proposed model can be used to create support systems for operational personnel managing complex technological facilities using specific procedures and instructions.
