Economic and Mathematical Modelling of Optimisation of Transaction Expenses of Engineering Enterprises

The article identifies stages of the process of optimisation of transaction expenses. It develops an economic and mathematical model of optimisation of transaction expenses of engineering enterprises by the criterion of maximisation of income from realisation of products and system of restrictions, which envisages exceeding income growth rate over the expenses growth rate. The article offers to use types of expenses by accounting accounts as indicators of transaction expenses. In the result of the study it is established that optimisation of transaction expenses envisages such a composition and structure of expenses, which would ensure achievement of the maximal financial result. Besides, the growth of the general volume of transaction expenses should be accompanied with reduction of its volume by a unit of product. Theoretical and practical significance of the obtained results lies in the fact that they could be used when conducting further scientific developments in this direction and also in the process of practical activity of enterprises. Application of the proposed economic and mathematical model of optimisation of transaction expenses would allow identification of the force and direction of influence of various types of transaction expenses upon income of a specific enterprise. Revelation of expenses, execution of which facilitates accumulation of volumes of realisation, and expenses, which hinder the process, would allow identification of the direction of regulation with the purpose of improvement of financial results of production and economic activity.
