Abstract
Introduction. The oil and gas industry plays a key role in the Russian economy. In this regard, it is necessary to ensure the safety of facilities in this industry, in particular the fire safety of oil refineries. Computer-aided fire-explosion safety systems play an important role in protecting objects and detecting fires on them. At the same time, a key element in these systems is special software and the success of the computer-aided fire-explosion safety system depends on it. Since the software is developed and operated by a person, there is a scientific and technical problem, which is expressed in determining the function of human influence on the special software of computer-aided fire-explosion safety systems. The work purpose is to assess the impact of human (programmer) on the stability of special software for computer-aided fire-explosion safety systems of oil refineries. Methods. The article presents a model of human impact assessment on the stability of special software for computer-aided fire-explosion safety systems. The model is based on the methods of system analysis and object-oriented programming. Results. A mathematical model of human impact assessment on the stability of special software for computer-aided fire-explosion safety systems is developed. This model allows us to obtain a formula for quantitative evaluation of the function of human influence on special software in its synthesis. Discussion. The article shows that the reduction of human (programmer) influence on the stability of special software of computer-aided fire and explosion safety systems lies in the plane of increasing the number of reusable elements—the basic elements of programs for the synthesis of single software systems. The reduction of influence is also achieved if such elements are created separately from the synthesis of single software systems on a particular tool. Conclusions. The results obtained by the authors can be used to assess the impact of human (programmer) on the stability of special software for computer-aided fire-explosion safety systems of oil refineries. In the synthesis of single software systems it is necessary to repeatedly use the basic elements of the programs. At the same time, the human impact on the stability in the synthesis of new versions of special software for computer-aided fire-explosion safety systems will be significantly lower.
