Operator Safety Information Capability
Abstract
Purpose: exploration of the method of determining the strategy for making a decision under various optimality criteria based on information from the object.
Method: The risk of accident accidents is determined by information about the parameters of individual system and equipment components (hereinafter referred to as signals). Signals are formed as a result of any material processes. A signal is the implementation of a random process that has a distribution that belongs to one of the non -intersecting classes. On the basis of signals, a decision is made, which is the result of the procedure. When making a decision, a minimum of average risk (Bayes criterion) is reached. The minimization is reduced to the use of the rule of maximum of plausibility, that is, to replace the implementation in the expression of the function of plausibility known as a determinism of signals and statistical certainty of obstacles and the selection of a signal that maximizes the function of plausibility. Methods of analysis and synthesis, statistical methods, and the counting theorem became the methodological toolkit of the conducted research.
The results of the study: an improved technique that allows you to reduce the number of errors when making a decision due to the selection of signals about the state of the object, which differ from each other to the extent that, under the influence of obstacles, their confusion does not occur when comparing objective external signals with their subjective semantic evaluation by the operator.
Theoretical implications: consists in the possibility of optimizing human activity, the goal of which is the safety and efficiency of managing complex systems using improved methods.
Value: the results can be used as a theoretical basis for the preparation of training programs and training of staff, which is in place when there is a high probability of a critical situation leading to a catastrophe (accident) and the purpose of training is to teach actions at the level of stereotypes.
Limitations of the study: the limitation of the study is the use of freely available information.
