Technological processes automation problems under ISO system development

Abstract

Society has always evaluated production on many indicators, including economic efficiency, product quality and environmental safety. Regulatory documents and technological regulations were used to ensure quality indicators.One of the most common international systems that performs the functions of harmonization of numerous national requirements for quality and environmental friendliness is ISO (International Organization for Standardization). Creation and compliance with ISO give significant results only with the cooperation of specialists working in various subject areas. The relevance of research is related to the importance of the competence of process automation specialists with ISO developers.The research was to determine the ways of applying the competence of automation specialists to create an ISO system on the example of alumina production. The article shows what actions and methods specialists can use using a known system (pyramid): Data - Information - Analysis - Knowledge - Solutions.Stage "Data" performs the analysis of the technological system and determines the important indicators of the technological processes, the place of their selection and methods of analysis. It is proposed to consider the measurement of the characteristics of substances and their evaluation by employees as equally important methods of obtaining data that can increase the reliability of the control system.Regarding the "Information" stage, it is said that there are certain transformations of data to obtain the objective properties of substances and characteristics of technological objects. It is taken into account that these transformations have some differences for the data, which are determined by technical means and organoleptically.It is determined that the stages "Analysis" and "Knowledge" should provide information about the current state of technological processes and provide knowledge about possible scenarios for the development of these processes and the identification of the current scenario. Methods of statistical analysis of information are most often used in quality management systems. It is indicated that the analysis of information can also be performed on the basis of empirical experience of employees.It is shown that the "Knowledge" stage is also related to the "Solution" stage. The Isikawa diagram has been developed as an example of the relationship between the characteristics of substances in a process system.It is noted that for decision-making in complex systems, which are technological systems of production, often use informal knowledge of specialists. The device that can be used at the decision-making stage, it is advisable to choose methods of artificial intelligence, in particular expert systems.The article describes the knowledge of specialists in automation of technological processes required for the creation and implementation of ISO. They justify the program of preparation of students or graduates for work in this direction of activity.
