Annotation:  The article deals with the problem of life cycle management of automated systems. Life cycle models were analyzed, domestic and foreign standards and industrial and corporate methodologies of information technologies development were investigated. The key features of major projects for automated systems design were defined. Based on identified shortcomings of existing life cycle models an integrated model of life cycle management was proposed as an algorithm, which is combining strengths of known models, taking into account the allocated levels of major projects implementation. The developed model is adapted for any phases and processes composition, which can be determined by developer. In view of outlined integrated life cycle model and bearing in mind the requirements on the need for using risk-assessment tools, database schema containing time and quality evaluation parameters of project and its individual components has been developed. The approach of preliminary data preparation has been proposed in order to create incoming vectors for training the neural network predicting the target deadline of project's different stages.

Keywords:  system analysis, life cycle model, automated system, system modeling, life cycle management methodology.
