Applied aspects of accounting the principle of the rule of law in system analysis and simulation of the state system of Ukraine

The rule of law is a fundamental principle of the legal sphere. Its assertion in the state institutions of democratic countries is an outstanding achievement of mankind. The implementation of this principle is the basis of civil society and civil liberties. The rule of law is the supremacy of law in society. The rule of law provides for its implementation in law-making and law enforcement activities. The manifestation of the rule of law is that the law is not limited to legislation as one of its forms, but also includes other social regulators (norms of morality, traditions, customs, etc., which are legitimized by society). All these elements of law are united by a quality that corresponds to ideology of justice – the idea of law, which is largely implemented in the Constitution of Ukraine. The first problem for the implementation of the principle of law in Ukraine is that this principle has not yet received the proper normative consolidation and official interpretation. The second problem is its extension to socio-economic rights and social benefits. The third problem is the insufficient level of legality in our state. The aim of the paper is to establish the peculiarities of implementation of the principle of the rule of law at the present stage of development of scientific and technological progress. The task of the paper is to investigate the peculiarities of implementation of the rule of law in the application of information and analytical technologies of system engineering in the legal sphere. In accordance with the experience of using information-analytical technologies of system engineering in the legal sphere, the paper outlines the peculiarities of implementation of the principle of the rule of law in the system analysis and modeling of the state system of Ukraine. The principle of the rule of law must be taken into account in such modeling as "governing circumstance". That is the resource according to which the state system of Ukraine functions. Our preliminary works give grounds to assert that information and analytical technologies of systems engineering are also a promising methodological tool for studying the principles of state building. The principle of the rule of law is the cornerstone of building a democratic state governed by the rule of law in Ukraine. Three years ago, scholars moved away from identifying the rule of law with the law-creating instruments.
