Assesment of the efficiency of risk management of the logistics system of the enterprise using the method of discriminant anakysis

This article solves the problem of finding an adequate technology of mathematical statistics that will increase the efficiency of risk management in the supply chain. The main goal of research is to improve the model for assessing efficiency of risk management of the logistics system, which will ensure a high level of accuracy in the classification of the population of the researched enterprises according to the levels of risk management efficiency. A critical analysis of scientific sources on solving researched problem indicates the wide use of methods for evaluating trade-offs between logistics risk and efficiency of logistics system and the feasibility of using discriminant analysis as the most acceptable of them. The relevance of solving this scientific problem lies in the fact that the timely improvement of the risk management of logistics system of enterprises by evaluating the efficiency of its implementation based on previously justified methods of analysis and modeling of risk management processes provides comprehensive countermeasures for various risks of internal and external environment of influence, preventing disruption of integration of logistics links and occurrence of material losses. The theoretical-methodical and practical basis of the research was made by the following methods: abstract-logical and generalization – while reserching scientific provisions of the theory of risk management for logistics systems of modern enterprises and methods of analysis and assessment of the efficiency of risk management; abstraction and formalization – while revealing the methodology of implementing discriminant analysis for evaluating the efficiency of risk management of logistics system; mathematical and statistical – while calculating and building a discriminatory model for assessing the efficiency of risk management of the logistics system of engeneering enterprises; generalization – while summarizing conclusions and recommendations based on research results. The object of research is risk management of logistics system of engineering enterprises. Research results established that the speed of rotation in the supply chain has the greatest influence on efficiency of risk management of logistics systems of engineering enterprises and the speed of turnover and the degree of customer service are less important. The carried out grouping of enterprises according to the level of efficiency of risk management of the logistics system determined five classification groups regarding their distribution: 40.74% of the analyzed enterprises are characterized by high, 15.93% – medium, 20.11% – sufficient, 17.14% – low and 6.08% is characterized by the critical level of risk management efficiency of the logistics system. A set of software products is recommended for each of the groups, which will ensure optimization and improvement of logistics processes, which has practical value.
