Abstract: The object of this research is the process of teaching mathematics to the economists and engineers. The subject of this research is the formation of skills for comprehensive and multilateral assessment of adequacy of the phenomena under consideration in the process of teaching mathematics to the economists and engineers. The goal of this work lies in structuring the model of multilateral assessment of mathematical activity (its objectives, methods, and results) and the application of mathematics as the component of economic and engineering education. The authors suggest the multi-criteria approach towards assessing the indicated phenomena on the basis of the original theory of modelling and theory of adequacy. The estimation of quality of the model in the theory of adequacy is defined via comparing the assessable model with the stated reference model. Research methodology includes the theoretical analysis of the modern mathematical education, theory of modelling, competence and activity approaches. In Y. B. Melnikov’s theory of modelling, the estimation of adequacy of the model is viewed as a result of comparison of the assessable and reference models. Evaluation of adequacy is viewed as a function, which arguments are the assessable and reference models. This allowed acquiring new scientific results: formalization of a specific attribute of adequacy can begin either with the structuring of reference model (with further concretization of the corresponding functions), or with the formation of the comparison method (with further determination of referenced model and formalization of the corresponding function).

Abstract: The subject of the study is a very important and urgent issue of modern education - the training of competent professionals who are able to make weighted management decisions in various fields of activity.The subject of the study is the role and significance of mathematical culture in enhancing the professional competence of students in economic and related areas of training.Particular attention is paid to the study of the connection between mathematical culture and professional competence. The modern state of mathematical education is described, the relation of mathematics and computer science is analyzed, the use of information and computer technologies in mathematical education is analyzed.The methodology of the study is based on the theory of modeling, based on the formal-constructive interpretation of the model. Methods of research: analysis of own pedagogical practice of mathematical education, analysis and synthesis of advanced Russian and foreign research, modeling.The main findings of the study are:1. The mathematical culture of the graduate and specialist remains one of the key components of the culture of modern society.2. The professional competence of the graduate and specialist includes a cultural component, of which the mathematical culture is an integral part.3. A specially organized mathematical education at the economic university allows successfully to solve the problem of increasing the professional competence of the graduate.The novelty of the research is that at the basis of this special organization is the model of mathematical culture as an infrastructure for the perception and processing of information and the exchange of information consisting of a system of phenomena, a system of relations, a system of interfaces and a management system.
