The object of this study is the process of estimation and control of an IT project. During the study, the problem of increasing the accuracy of estimating the efforts of an IT project to build an information system (IS) was solved. Research in this area is aimed at simplifying the original assessment methods or at applying elements of artificial intelligence to these methods. The task of the impact of the features of IS development methodology on effort assessment remains unexplored. During the study, the method of functional point analysis was modified. The proposed modification makes it possible to increase the accuracy of estimating efforts to build an IS under the conditions of re-using its individual functions. These conditions allow the construction of new system functions by reusing a previously developed function of the same system. The developed method was tested during the evaluation of efforts of an IT project to form the functional task "Forming and executing an individual plan for a research and teaching staff member of the department." The option of re-using one of the functions of a task during the construction of two other functions of the same task is considered. For this option, the estimate was 72 function points (the estimate using the standard method was 144 function points). The use of the results allows us to increase the accuracy in assessing the efforts of IT projects to construct IS under the conditions of applying the methodology of reuse of previously developed system elements. This, in turn, makes it possible to improve the accuracy of estimating time costs, personnel requirements, and financial costs for the implementation of IT projects for constructing IS. The results obtained are used to solve the task of estimating efforts during the planning of IT projects for developing information systems and their software. [ABSTRACT FROM AUTHOR]

The appearance of "blurred" digital images is a consequence of the violation of the immobility of the camera during the shooting of the objects under study. To this end, a procedure was devised for matched filtering of the blurred digital image of the object using its typical image form in a series of frames. This procedure is based on the automated formation of a typical form of a digital image, as well as on the choice of special parameters for the transfer function of the matched filter. Adapting the procedure specifically to the typical form makes it possible to perform a more accurate assessment of the required parameters of the blurred digital image compared to the analytically set profile. The formation of a typical form makes it possible to take into account the features of the very formation of the blurred image on each frame of the original series. Based on this, a more accurate assessment of the initial approximation of the parameters of all Gaussians of the object image is performed. In practice, matched filtering makes it possible to highlight blurred images of objects against the background of substrate noise. Also, using the matched filtering procedure makes it possible to improve the segmentation of images of reference objects and reduce the number of false detections. The devised procedure for the matched filtering of a blurred digital image using its typical form has been tested in practice as part of the research in the framework of the CoLiTec project. It was implemented in the intraframe processing unit of the Lemur software for the automated detection of new and tracking of known objects. Owing to the use of Lemur software and the proposed computational procedure introduced into it, more than 700,000 measurements of various objects under study were successfully processed and identified.

The main purpose of modern information systems (IS) is to support the procedures of controlling many business processes (BP) of an enterprise. At the same time, due to a weak formalization of BP, processes of development, reengineering of various service-oriented IS and IT services are a complex problem. To address this problem, the task to improve the method for choosing IT services that meet an assigned set of functional and non-functional limitations was stated. The specific features of the original method for choosing IT services were analyzed, its main shortcomings were identified. The model of the BP precedent was modified to establish the relationship between descriptions of the precedent, functional requirements, and the used IT services. The method for selecting IT services for the IS was improved by adding the functions of requirements analysis and searching for descriptions of IT services that partially meet the stated functional requirements. In the method, the adaptive linear associator of the mADALIN neuron was used to quantify the degree of match of the functional requirement and the description of the function of the IT service. These proposals were the basis for the improved method for selecting the IT service that best fits the set of constraints that are formed. Based on the result of the conducted research, an experimental test of the improved method for selecting an IT service to solve the problem of automation of the activities of sale force of the electronic policy OSAGO was carried out. The information technology implementing the original method for choosing IT services was compared to the improved method. It was shown that the improved method makes it possible to identify situations of a match of functional requirements of a customer and the descriptions of IT services. This makes it possible to select those IT services that match the functional requirements to a degree above the assigned minimum limit. [ABSTRACT FROM AUTHOR]
