INFORMATION SYSTEM SIMULATION SYSTEM CONCEPT
The development and implementation of information systems is a complex and time-consuming process. Significant costs are required at all stages of the life cycle. The aim of the research is to describe the concept of information systems modeling methodology. As a result of the study, the concept of the methodology for modeling information systems is described, which allows, on the basis of a single graphical notation, to analyze the business processes of the automation object, their restructuring and, on the basis of these results and the set task, to develop models of information and software.
