Abstract: To date, the introduction of electronic document management and records management in the executive bodies of state power remains one of the most urgent tasks. The authors consider the use of "soft" mathematical modeling in developing a mathematical model for assessing the implementation of electronic document management systems and records management. By mathematical modeling, the work is understood as the process of establishing correspondence to the real object of a certain mathematical object, which is called a mathematical model. The object of modeling is the system of electronic document circulation and records management. The main objectives of modeling the study of document flow in the executive bodies of state power are: to increase the effectiveness of management activities, accelerate the movement of documents, reduce the complexity of processing documents.In this work, the authors used the formalization method, which consists in studying objects by displaying their content and structure in sign form. The main conclusions of the study are that, using "soft" mathematical modeling, a mathematical model for assessing the implementation of the electronic document management system and office work in the executive bodies of state power is constructed. After studying the constructed oriented graph, a system of differential equations is written that corresponds to the following rules: equations as many as there are unknown quantities, model parameters (system coefficients) are found as a result of application of computational methods.
