DEVELOPMENT OF AN INFORMATION SYSTEM FOR SUPPORTING DECISION BASED ON SYSML

Abstract

The process of creating an information system to support product quality decision to facilitate decision-making during monitoring of the technological process and its forecasting in conditions of multifactoriality and uncertainty is considered. The aim of the article is to design an information system supporting decision-making by product quality, namely butter production. The realization of the set goal involves the use of the SysML methodology in accordance with the ISO/IEC/IEEE 42010:201 standard, which allows specifying, visualizing and constructing various software aspects of the system. Scientific novelty. Designing an information system using the system engineering language SysML allows you to show multi-component subsystems at the early stages of their creation. The article contains both requirement and sequence diagrams. Conclusions. There are some issues in modern standards, specifically in the process of the creating of the decision support information systems for technological processes. There is shown the feasibility of using SysML system engineering methodology based on standard diagrams. The developed diagram of the requirements demonstrates the interrelationships and mutual influences to the general and clarifying requirements in the design of the information system to support decision-making by product quality. Sequence diagrams are used primarily to show the interaction among different objects in the sequential order in which that interaction occurs. The developed diagrams make it possible to facilitate the integration of the decision support information system into the subsystem of the automated control of the technological process to ensure proper functioning in real time, to have a connection with the lower-level automation system and upper-level dispatching systems, and the database.
