Optimization of technological specifications and methodology of estimating the efficiency of the bulk cargoes delivery process

Abstract

Purpose. To increase the efficiency of the process of bulk cargo delivery by exit routes by optimizing the techno logical parameters of the supply chain. methodology. The optimization of the technological parameters of the supply chain for cargo delivery was carried out using mathematical modeling. To assess the effectiveness of the process of cargo delivery, an analytical method of research was applied. Findings. As a result of the research, optimum values of the technological parameters of the production and trans portation chain of ore cargo delivery by exit routes were obtained: the composition of the formed route is 38 cars, the loading point performance is 324.2 t/h, the delivery interval is 1.75 days. Using the optimal technological parameters of the supply chain for the delivery of bulk cargoes by exit routes, the operational work of the railway transport is planned, ensuring compliance with the delivery interval for the purpose of implementing the requirement "just in time". The dependences of the specific costs of these parameters, which allow evaluating the nature of their changes in various given conditions, are constructed. Originality. The components of the economic effect of the supply chain for the delivery of bulk cargoes (coal, ores, etc.) by means of exit routes have been formalized and a method for evaluating the economic effect for both subjects of the supply chain is proposed: the owner of cars and production. Practical value. Recommendations on the formation of the technological process of functioning of the entire sup ply chain are given for given values of the duration of the supplier's and customer's production cycles, the duration of transportation, the intensity of the input of the delivered raw materials into production. To improve the efficiency of delivery of bulk goods, it is recommended to use the developed schedules of interaction between production, trans port and consumption. At the same time, the intensity of raw materials receipt into production determines the opti mal composition of the formed exit route and the delivery interval.

Development of a multimodal (railroad-water) chain of grain supply by the agent-based simulation method

“…When running the model with different sizes of the transport fleet, delivery time ranges from 180 to 400 hours. This range corresponds to the existing actual and normative values of the time of cargo delivery by multimodal railroad and water routes at the distance of 1,500-3,000 km [26].…”

“…One of the most important areas of improvement of the system of car flows organization is the dispatch routing [9]. However, the existing system of substantiation of routing does not fully take into account the peculiarities of cargo formation at loading points [10].…”

Analysis of the grain market in Ukraine and directions for the development of logistics for the transportation of grain cargo

“…Studies [14,15] show that forwarding routing is one of the most important areas for improving the system of organization of carriages. Implementation of routing provides acceleration of delivery of goods to consumers, more efficient use of shunting means, reduction of downtime of wagons at technical stations, during transportation.…”
