摘要：The efficiency of risk management software depends on the quality of risk assessment at the
stage of such system development. The number of potential variables (factors) in many risk management
software applications is large. Another important aspect is that the scientists and engineers face to
challenge which risk factors are significant or what the acceptable range of its values is at the initial stage
of the risk controlling system development. The paper suggests a way to determine the significant
specific risk factors of domestic oil and gas production enterprises’ activity and to screen out the
insignificant factors. In order to achieve these goals, the simulation analysis was conducted by the aid of
2-level full factorial experiment. Empirical data-processing operation was carried out through the
instrumentality of mathematical statistics methods. It has been suggested to exclude (screen) at the
stage of model construction eleven risk factors (of thirty-five ones identified), which impact on the
financial and economical state of analyzed companies is insignificant (less than 5%).
