The positivity and asymptotic stability of descriptor linear continuous-time and discrete-time systems with interval state matrices and interval polynomials are investigated. Necessary and sufficient conditions for the positivity of descriptor continuous-time and discrete-time linear systems are established. It is shown that the convex linear combination of polynomials of positive linear systems is also the Hurwitz polynomial. The Kharitonov theorem is extended to the positive descriptor linear systems with interval state matrices.
The article deals with the peculiarities of an economic evaluation of administrative systems in the context of management business processes reengineering. In particular, methodological approaches to the economic evaluation of such systems are described and characterized. It is concluded that under present conditions most of the projects on construction or improvement of administrative systems belong to the category of investment projects, which, accordingly, are related to investment costs.

The main consequence of the evolution of performance management over the last decade is to focus not only on goals but also on means.
Running editorial board of a scientific journal or organizing an academic conference (including managing its program committee) is a complex multistage process that requires effective information Lviv Polytechnic National University Institutional Repository http://ena.lp.edu.ua 22 management with application of modern information and communication technologies. These activities are usually cyclical, repeating with each new journal issue or recurring event.
The article presented the views of different scholars on the definition content of "regulation". This concept was derived from "regulate" and that has been represented in many sources were found. It was considered the author of a number of scientific resources were analyzed and identified the major common features in the studied categories. The basic part of research was divided into two parts : focus on regulation as a function of component management, and studying its subtypes on governmental level. The purpose of the article was to study the semantic content category "regulation".
This article describes the architecture of cloud services and key technologies for algorithm selection services. Cloud computing is relevant to various types of software and distributed computing based on Internet access, which means that users can get an access to applications and storage from remote servers using web browsers or other stationary or mobile terminals. Resources of stationary and mobile terminals are limited, which is why cloud computing is the right tool that will provide different kinds of terminals with powerful resources to achieve complex services.
The article deals with the features of the system of checks and balances as one of the indicators of democratic development. Taking into account the peculiarities of modern political transformations in the world, the new approaches to the understanding of the system of checks and balances in the political sense are emphasized. Basing on the analysis of the political practice of democratic states, the key features of the system of checks and balances are identified and it is proved that this institution is multidimensional.
In the article in general theoretical aspect highlighted features of the interpretation of a modern system of sources of law in Ukraine, taking into account the latest research. The emphasis on the key problems of the domestic system of sources of law, which in these conditions is imperfect and unstable, which is characteristic of regulatory complexes of transition, creating in turn the relevance, appropriateness and timeliness of the study of the subject in the domestic legal science.
The methodology generally has two meaning: as a system-defined methods and techniques used in a particular field – science, politics, etc., and as the study of this system as a general theory of method, theory in action. Therefore, the methodology – a philosophical theory of system methods of scientific knowledge and the transformation of reality, and the doctrine of the application of the principles of the laws of dialectics and science to the process of learning and practice in the interest of acquiring new knowledge.
