FORMING OF A RATIONAL SCHEME OF SERVICING ORDERS FOR CARGO DELIVERY BY THE FREIGHT FORWARDING COMPANY
The paper analyzes this day state of development and current trends in the forming of a rational scheme for servicing cargo delivery orders within the framework both individual enterprises and transport on the whole. It’s allowed to form the main purposes of the study this article. The scientific works about the cargo delivery improvement by the freight forwarding enterprise focus 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 a rational order servicing scheme to further reduce the cost of cargo delivery and accordingly to increase the profits of freight forwarding enterprise. Seven alternative schemes of servicing the order for the cargo delivery by the freight forwarding company have been proposed. They take into account the possible combinations of the relevant operations list execution that accompany the transport process organization and realization. The process of choosing a rational scheme for the cargo delivery is guided by the maximum profit and considers the established parameters, such as: the customer service scheme, the transportation distance, the volume of cargo. In order to obtain the most reliable data on the parameters of the transport process, the required number of observations has been determined; it amounted to 127 observations of the volume of shipment, and 142 ones of the delivery distances. The developed plan of full-factorial experiment allows to adequately assessing the effect of initial parameters (a shipment volume and a delivery distance) on the efficiency criterion (an enterprise's profit). The model's reproducibility check was performed with use Cochran's criterion, that was amounted 0.9779; it means the experiment can will be reproduce. According to certain assumptions, values of initial data and duration of operations that were performed by the enterprise, it has been calculated the values of the elements of the estimation indicator – income and expenses for each scheme of service, as well as the efficiency criterion – the profit. On the basis of the regression analysis of the experiment's results, a regression model in linear form with a non-zero coefficient has been determined, in which each coefficient indicates the respective factor influence quantity on the resultant indicator – the profit. It is found this model is the most adequate because the value of the "R-square" is the largest and equal to 1. The results of the profit determination showed that the highest level of the indicator is achieved when servicing the order for cargo delivery of 21.45 tons for a distance of 1817 km according to the scheme service № 5; it is the least costly in terms of number of services, time of work execution, when the vehicles and handling machinery are used effectively enough. In this case the company makes a profit of 28951.86 UAH, which is many 26292.69 UAH than servicing the order the existing in the enterprise scheme № 2.
