Modelling, Analysis and Risk Assessment in the Technology Process Control

The present article is dedicated to the research in the field of analytical support of hazard management decisionmaking in the technological process. The essential component of qualitative and safe products manufacturing is on-line (immediate) and proper decision-making. Difficulties arising in the course of decision-making are lack of knowledge regarding objects characteristics in abnormal situations as well as ambiguity in decision results’ evaluation. Objective and ontological models of technological process hazard control of food production are presented in this article. The description of hazard assessment ontology with the integrated Bayesian Belief Network is shown hereby. Qualitative and quantitative hazard assessment analysis is made with the usage of risks and hazards identification method as well as Bayesian method of hazards statistic assessment. Keywords–hazard analysis, hazard control, ontology, technological process.
