The paper pays attention to the consideration of the structure of user's information support of the airspace control system at the stage of primary information processing by the joined radar system. This system includes a primary and identification surveillance system, which allows considering the overall structure as a single synchronous network of surveillance information systems. Such a structure can be characterized by an overall integrated quality indicator of the information support of the airspace control system. Such a quality indicator can be the probability of information support, which is the product of the probabilities of correct detection of an air object by the primary radar and identification system on the basis of "friend-foe" and the probability of comparing the coordinate information of primary radar systems and identification systems. This approach allows changing the model of combining information for primary radar systems and identification systems so as to take into account the estimated coordinates of the air object by both information systems due to the weight combination of coordinates of air objects. The calculation of the coordinates of air objects according to the information of the primary radar systems and identification systems allows improving the quality of information support for decision makers in the air traffic control system.

The article substantiates the role of information systems and technologies in the management of accounting and analytical process at the enterprise. The advantages and disadvantages of using informationsystems and technologies have been listed. It has been determined that the observance of the quality of information support is possible under the condition of observance of the principles of systematization, complexity, scientificity, reliability, expediency, efficiency, priority, transparency and target direction. Applied programs of domestic and foreign accounting experience have been given. An assessment of the use of computers at the enterprise and the use of the Internet in Ukraine have been carried out. After analyzing the useof the Internet, it was determined that since 2010 to the present, the share is growing accordingly. And theInternet is mostly used to send or receive e-mails (70,65%-98,84%), receive information about goods andservices (44,52%-89,22), make banking operations (81,53% -97,65%). A study of the number of companiesthat used computers by industry found that the largest number of companies are manufacturing and wholesale and retail ones.

Decision support systems (DSS) are interactive computer-based systems that provide information, modeling, and manipulation of data. DSS are clearly knowledge-based information systems to capture, Processing and analysis of information affecting or aims to influence the decision making process, performed by people in scope professional job appointed by a user. Hence, this study describes briefly the key concepts of decision support systems such as perceived factors with a focus on quality  of information systems and quality of information variables, behavioral intention of using DSS, and actual DSS use by adopting and extending the technology acceptance model (TAM) of Davis (1989); and Davis, Bagozzi and Warshaw (1989).There are two main goals, which stimulate the study. The first goal is to combine Perceived DSS factors and behavioral intention to use DSS from both the social perspective and a technology perspective with regard to actual DSS usage, and an experimental test of relations provide strategic locations to organizations and providing indicators that should help them manage their DSS effectiveness. Managers face the dilemma in choosing and focusing on most important factors which contributing to the positive behavioral intention of use DSS by the decision makers, which, in turn, could contribute positively in the actual DSS usage by them and other users to effectively solve organizational problems. Hence, this study presents a model which should provide the useful tool for top management in the higher education institutions- in particular-to understand the factors that determine using behaviors for designing proactive interventions and to motivate the acceptance of TAM in order to use the DSS in a way that contributes to the higher education decision-making plan and IT policy.To accomplish or attain the above mentioned objectives, the researcher developed a research instrument (questionnaire) and distributed it amongst the higher education institutions in Jordan to collect data in order to empirically study hypothesis testing (related to the objectives of study). 341 questionnaires were returned from the study respondents. Data were analyzed by utilizing both SPSS (conducted descriptive analysis) and AMOS (conducting structural equation modelling).Findings of the study indicate that some hypotheses were supported while the others were not. Contributions of the study were presented. In addition, the researcher presented some recommendations. Finally, this study has identified opportunities for further study which has progressed greatly advanced understanding constantly of DSS usage, that can help formulate powerful strategies Involving differentiation between DSS perceived factors.

Systems developers and IT project managers who apply agile methods for developing information systems (IS) subscribe to a set of values and principles. This adherence to a set of values and principles, along with a passion or fervor surrounding the agile philosophy, made us question whether the adoption of agile methodologies has an effect on information systems built, and in particular, the quality of the IS developed. In this paper we construct a conceptual model, conduct a survey of software developers, and analyze our results, which support our hypotheses about the importance of the strategic selection of a development methodology. We conclude that practicing project managers should consider the decision to use certain methodologies as part of the strategic process.

The dependence of management decisions on information support is not a debatable issue for a long time. However, the changing quality of information creates both new challenges and new opportunities in the information and analytical field. The decision-making process, which would seem to be facilitated by digitalization, is actually becoming more complicated. As one of the main effects of digitalization, we note the apparent availability of information. In fact, simple facts that create an information network no longer become, moreover, they become smaller, or rather, their availability decreases. The necessary information sinks in the ocean of information noise. Echo chambers and filter bubbles exacerbate this problem. At the same time, the possibilities provided by the effects of echo cameras and information bubbles remain low.
