The article presents the analysis of approaches connected with solving the problems of increasing the effectiveness of managing the processes of goods movement in the supply chains. The attention has been focused on estimating the qualitative component of transport services, and that is the reliability index. The approaches focused on improving the efficiency of providing transport services have been studied. The main parameters influencing the reliability of transport and logistics services are identified: time, qualitative and quantitative characteristics of the goods, as well as the financial component – the cost of the provided transport service. A new methodical approach to estimating the reliability of goods flows in the supply chains is proposed. It is based on the main principles of the theory of automatic regulation and the determination of the reliability of technical systems. A complex index of reliability of transport services of logistics chains is offered: the readiness coefficient and the technical use coefficient. On the basis of structural and parametric identification of the dynamic model of the logistic system of goods transportation, the considered approach allows identifying a large number of constructive and technological parameters which affect the movement of goods flows in the supply chains. The results of the simulation allow one to analyze the influence of the time constant  which characterizes the response time of the links in the transport and logistics system, that is, the ability of the transport service participant not to respond to any external influences, and the influence of the time constant  which is responsible for delays, non-productive time losses occurring during the delivery of the goods, on the dynamics of the transitional processes of the goods flow movement for each link in the supply chains. The elaborated method allows developing managing actions aimed at improving the quality of transport services.

The paper analyzes this day state of development and current trends in improving to the grain delivery quality management by the motor transport, within the framework both individual enterprises and the industry on the whole. It’s allowed to form the main purposes of the study this article. The scientific works about the grain delivery quality by road transport give main attention on the development of effective interaction between the process participants, but they don't consider possible changes in the execution of technological operations under the impact of relevant factors. It has been determined there is a need to choose a methodical approach to form effective grain delivery quality management to further reduce the cost of performed operations and accordingly to reduce grain losses. The structure of the process of grain cargo transportation quality management has been considered, namely: the place of transport processes in the functioning of the grain products subcomplex is determined; the scheme for the movement of grain cargoes along the routes is developed. Based on the known initial system's parameters (number of motor vehicles and specialized transport), output parameters (the grain loss throughout handling operations and transportation) and external ones (total amount of grain that was collected and transported, the prime cost of grain transportation, the coefficient of the spilling grain, the cost of grain), the object of study has been schematically presented in the white chest form. An analytical model in the form of total grain losses during the transportation has been constructed. A full-factorial experiment plan for five initial parameters consisting the 32 series of tests has been developed. At that the various combinations of external influence parameters, with appropriate intervals varying in number, have been used. As a result of experiment the values of grain losses during transportation by series of tests have been obtained. It has been determined that the numerical values of the two main parameters (the volume of transportation and the cost of freight) take on maximum ones. A regression analysis by linear function has been performed. With the help of Microsoft Excel some indicators have been calculated, such as the coefficients variables in an equation, the variance, the regression statistic, etc. The got model is found to be adequate because the value of R-squared goes toward 1 and equals 0.785. The values of the regression model coefficients as well as their adequate to the standard error, t-statistic, P-value, lower and upper value has been also checked. It has been established the obtained model allows to predict the system's conduct and to manage the grain delivery quality by the Ukrainian territory for the Company “HARMAR-Service”.
