Abstract:

   In the article the need to take into account the ergonomic component (i.e. human operator) of the ergatic system is proved. Methodology for studying the human operator reliability in ergatic systems of monitoring and protection of environmental objects, based on the hypothesis that a person in the system perceives signals and reactions as any other technical elements is proposed. The methodological approach for assessing the human operator reliability in an ergatic control system using experimental data is presented on the example of a manual trigger of a fire alarm system, based on the expression of a standard pointer in the form of a readiness factor of technical products.

   For the experiment, a laboratory installation was created, simulating a fire alarm device (light and sound) based on a serial smoke detector of IPD-3.1M type, equipped with an additional electric sensitive stopwatch with a division value of 0.01 seconds, a manual emergency serial starting device of IPR-3SUM type, an element of remote control of EDU 513-3M type, which made it possible to carry out experiments to study the human operator reliability. This installation allows studying temporal characteristics (speed, inertia), the human reliability in terms of professional suitability in different areas of activity, such as driving vehicles, dispatching service, managing fast processes, etc.

   The experimental research results and their statistical processing: the approximation of empirical data by the method of correlation-regression analysis and the assessment of the adequacy of the approximation of experimental results using the Fisher’s goodness-of-fit test are presented.

   Further research perspective is to assess the human operator reliability in an ergatic environmental control system by using the methodology described in this work for various age groups (30-, 40-, 60-year-olds) and their comparative characteristics and analysis.

Keywords: reliability, ergatic control system, human operator, reliability assessment, methodological approach.
