Abstract

Automated workplaces are an integral part of any enterprise, including those in the aerospace industry. Errors that may occur at the automated workplace exert a negative impact on the activities of an individual company, as well as on the industry as a whole. At present, there are solutions to this problem, but they are being realized manually using software utilities to rectify some of the identified problems.

The purpose of this work consists in creating the structure of the decision-making system in case of automated workplaces failures and the formulating the decision-making criteria.

The following errors and failure factors were revealed while the errors statistics analysis process. The conducted studies allowed developing a mathematical model of the decision-making system and its subsystems.

The effectiveness criterion is optimization of the working places users activities by reducing the time spent the failures detection and elimination.

The following results were obtained.

The study of the failure statistics, allowing identify and describe statistical dependencies in the form of a mathematical model, was conducted.

A conceptual model of the decision-making system in the event of automated workplaces failures, consisting of four interconnected subsystems, has been developed. Management tasks for each of the subsystems were formulated. This is the scientific novelty of the presented results.

The system functioning allows ensuring the smooth operation of the automated control system, or reduce to a minimum the amount of the time spent on solving the problems of failures, which defines its practical meaningfulness.

Keywords:
