Experience of digital simulation of the Constitution system of Ukraine in the IDEF0 notation

Abstract

Object and process modeling allows to solve problems in systems. Therefore, developing a model of the Constitution of Ukraine using software is an urgent task for domestic jurisprudence.Previously, the authors conducted a systematic analysis of the Ukrainian state system and proposed its cognitive model in IDEF0 notation. We used the same notation to model the crime system and its prevention system. Hutsa O.M., Obolentsev V.F., Demchenko O.V. developed a technology for modeling and detecting algorithmic errors in software regulatory acts.The paper demonstrates the results of modeling the Constitution of Ukraine as a system in IDEF0 notation using CASE technologies (Computer Aided System Engineering - computer aided design) Microsoft Visio.A two-tier model was built. The context diagram of the decomposition outlines the flows of the system interaction under study with the external environment: 1) input flows, which are converted into output flows (information and documents for the implementation of public authorities’ activity; staffing  resources for positions of civil servants); 2) incoming flows of governance (universal, equal and direct suffrage; the Declaration of Independence of Ukraine of August 24, 1991; the rule of law principles, independence, collegiality, transparency, validity and obligation of court decisions and conclusions; popular initiative; voter will); 3) input flows of enforcement mechanisms (people of Ukraine; state bodies); 4) outflows - the system results (human rights and freedoms and decent living conditions; civic consent in Ukraine; democratic, social, rule of law; balanced budget; monetary unit; State Flag of Ukraine, Grand National Emblem of Ukraine, National Anthem of Ukraine; civil servants appointed to the positions).The second level of the model is a decomposition diagram that reflects the set of system elements (sections of the Constitution of Ukraine) and their interaction with the external environment and with each other
