This study investigates the process that controls the IT project configuration.
The study addressed the problem of early identification of configuration items (CI) within an enterprise management information system (IS). Modern research in this area is mainly aimed at solving the task of services early identification during refactoring of software systems. The issue of applying artificial intelligence methods and, in particular, clustering to detect CI at the early stages of the IS life cycle has not been studied sufficiently.
The aim of the study is to develop a new or improve an existing method for solving the task of early identification of IS CI.
To achieve the aim of the study, the existing method of synthesizing descriptions of rational architecture creating IS based on descriptions of functional requirements for this IS was improved. The essence of this improvement is to use the DBSCAN clustering algorithm to detect architectural entities as clusters of individual IS functions. The results of solving the clustering task make it possible to simplify the description of the architecture creating IS by significantly reducing the number of CIs, provided that descriptions of architectural entities as clusters of individual IS functions will act as CIs.
The main features of the course and results of the experimental verification of the improved method are considered. The descriptions of ten functions of the task “Formation and maintenance of an individual plan of a scientific and pedagogical employee of the department” were used as the derived data for this verification. The result of using the method is three solution options, presented in the form of sets of one or two clusters. These options describe monolithic, modular and service-oriented IS architecture.
The use of the obtained results allows you to automate the procedure for synthesizing the description of the IS architecture. This automation will increase the quality of IS development by allocating a set of architectural entities of this IS for design. This set is much smaller than the set of elementary IS functions.
