Comparative Vendor Score

This paper analyzes the components of the linear form that defines the method for evaluating supplier companies. Evaluation is carried out from the point of view of the single consumer. Factor analysis has been done on the basis of the data obtained about the supplier companies of Russian railways company.


Introduction
The task of choosing vendors by clear and simple mathematically sound estimates is highly relevant today (see.[1][2][3][4][5]).In this work we consider the method of calculation of the vendor score and received from it the comparative score, developed in [6].
In the factor analysis, we obtained a set of indicators that determine the production and business activities score of the vendor.This is done from the point of view of the consumer -Russian railway company [7]., где ܸ ௪ -amount of working capital.

Calculation of the vendor scores
The formula contains a value ߚ ௧ , ߜ ௧ , ߯ ௧ and ߛ ௧ that having the following economic sense: ߚ ௧ -the optimum value of the share of vendor cross section in question, directed to the consumer company in relation to the total amount sold by the vendor; ߜ ௧ -optimal level of profitability for businesses in the cross section in the industry in the current economic situation, %; ߯ ௧ -the optimal size of leverage in the cross section in the back of the enterprise in the industry in the current economic situation; ߛ ௧ -optimum level of capacity utilization in the cross section in the vendor of the industry in the current economic situation.The values ߚ ௧ , ߜ ௧ , ߯ ௧ and ߛ ௧ of the optimum values set us empirically, based on practical experience.In further studies are subject to change and are derived from statistical data.

Conclusion
Developed a linear form, which allows you to compare vendors.Comparison is made on economic parameters.The behavior of individual indicators form will be examined in further studies.It is of interest to create a comparative measure of the absolute evaluation to obtain the normalized vendor.
