The task of procurement management is key in the management of business enterprises of trade. Even small businesses that have a wide range of products, it is necessary to implement automated procurement management system. This raises the question of the effectiveness of applied information technology pro-curement management, which is determined, first of all, the quality of the brainware. The quality of the ap-plied mathematical apparatus, depends on the effectiveness and cost of software procurement manage-ment system. The paper presents the basic model of inventory management, made a brief comparative analysis of the models and optimization techniques, and methods of statistical analysis and sales forecast-ing.

Exit trading enterprise to a new regional market is a common market strategy, which is used by both large and relatively small trading enterprises. However, a poorly studied region is fraught with danger of becom-ing a problem for the company. Typically, the problem arises not only from an underestimation of the com-petitive environment, but also with a lack of understanding of other consumer preferences in a new region. Therefore, the entrance to the new region must be preceded by a marketing research and market analysis. The paper presents the research methods of the regional market of consumers choosing the optimal loca-tion and analysis of the competitive environment in point of sales. These methods are included in the total output of the enterprise technology to a new regional market.

In article problems of teaching of mathematical disciplines at economic universities are considered. The analysis of a state of preparation of entrants last years on the basis of researches PISA and the report of UNESCO on formation in the world is carried out. It is shown that in the conditions of an insufficient financ-ing of education in the Russian Federation and low level of preparation of entrants in the basic subjects, it is necessary to optimize curriculums and to use new educational technologies. It is offered to use the free software designed for carrying out mathematical and econometrics calculations, unique system of genera-tion of examinations and tests, the modern language of programming optimized for use by students of economic specialties, profound studying of tabular processor Microsoft Excel.

Assortment management is the main task of trade enterprises. Assortment is a basic tool in the marketing mix, it affects the sales and distribution costs.

Some generalization of classical model of market balance (Valras's models) are made. Nonlinearity of laws of the demand and supply, dependence of these laws on change in price speed are considered. Specific examples of application of models are reviewed.

In work application of a packet of visual modeling of Simulink for the description of the main transactions of financial mathematics is considered. Benefits and possibilities of this tool are listed. The main stages of modeling are stated. Models of calculation of the increased amount when using the scheme of charge of simple and compound interests are constructed, and also models of transactions with flows of payments.
