Abstract It is emphasized that for the safety and operation of the software distributed information-control systems (software DICS) it is necessary at an early stage of the life cycle design (creation) of software DICS to conduct a pre-investigation, one of the tasks of which is to identify and analyze risks and develop the criteria for risk management in the condition of single-parent, interval uncertainty initial data. We consider the key concepts used in creating of software DICS, as well as the main reasons for the lack of a common understanding of the risk categories, methodical approach to determining the factors causing the occurrence of risk and generally accepted risk assessment techniques. We present a generalized scheme of project risk management software for creating the DICS with a detailed description of each stage of the management. To reduce the risk at the stage of pre-project studies in creating the DICS software it is proposed to use the method of precedents that can improve the quality and efficiency of the solutions in the development of new projects by adapting solutions that have been used previously in similar situations. Proposed is the model of risk reduction at the stage of pre-project studies in creating the DICS software using the method of precedents, as well as the physical model of the precedents database in IDEF1X notation. To correctly extract the precedents from the database the "nearest neighbor" method is offered. We consider a small example of the method of precedents application in creating the DICS software, which allows the project managers to choose acceptable alternatives to software development in the conditions when it is impossible or not advisable to construct mathematical models with application of the program system developed by authors.
