It is believed that a business process may be revealed using a bottom-up, but the model obtained in this way overloaded with details, are difficult to understand and often just provide a description of an individual script execution. The methods of model construction process using a top-down, highlighting all of the scripts execution is presenred. The result is a multi-level hierarchical model, suitable for analysis.

The article analyzes non-stationary arising in the process of project management at the industrial enterprises and their effect on the project structure. The method which provides accounting of non-stationary in the project temporal-logical model structure is presented. An example of the practical use of this method is given.

The goals and features of laboratory tools based on the open systems concept for studying the cluster systems scope and functioning properties, which allows to solve the problem of choosing the computational process rational organization taking into account the cluster system and technical parameters as well as the interaction tasks and their characteristics. In order to select the rational construction the GPSS World simulation
models were developed.

This article describes a program model for delivering local content to mobile subscribers. SpotEx application can use any Wi-Fi access point as presence sensor that discovers local data to mobile subscribers. SpotEx is a production rule-based expert system that opens access to local messages depending on visibility of Wi-Fi access points.

This paper presents a historical overview of the process of formation and development of informatics, as well as the formation of concepts. Considered several options for treatment of the concept of «informatics» as a field of scientific knowledge. Recommendations are given for the construction of training programs for bachelor’s and master’s degrees in information technology, in particular, for periodic updating according with the development of concepts and technologies.

It is known that during evolution process new genes may be constructed by a combination of existing genes. The combination mainly based on two processes: fusionиof genes or parts of genes and insertion of one gene or part of gene into another. Triplet periodicity of coding sequences is a common property of most living organisms. The fusion and insertion events may give triplet periodicity change points in a corresponding position of the gene. For the change point analysis measures of difference and similarity of triplet periodicity were introduced. Based on these measures the mathematical method for paired and single change point search in genes was developed.
