DETERMINATION OF LOGISTICS PARAMETERS OF E-CARGO BIKES FOR SUSTAINABLE DELIVERY OF POSTAL CARGO IN CITIES

Abstract

The article is devoted to formation of parameters of logistics system of cargo transportation using «green technologies». The feasibility of using a distribution center with certain parameters of the supply chain is assessed. The solution of the problem of choosing the location of the logistics center was solved simultaneously with solving the problem of routing and choosing the carrying capacity of the vehicle. The number and configuration of transportation routes depends on the volume of cargo delivery, the location of the consignor and consignees, as well as on the carrying capacity of vehicles. Each location of the distribution center determines the number of routes, the distance of transportation, the volume of traffic on each section of the routes. As a result, it was proposed to use the value of the transport work of rolling stock as an indicator that takes into account these components. The initial data for determining the effective location of the distribution center is the volume of traffic for each sender and the location of consumers. In connection with the current trends in the development of "green technologies" in urban logistics, the question of the feasibility of using freight electric bicycles at the proposed location of the city logistics center was considered. When using green technology, electric cargo bicycles were considered as vehicles. The solution to the problem of determining the most efficient distribution center was carried out taking into account the possible carrying capacity of electric bicycles. A number of bicycles with different carrying capacities that can be used to transport mail cargo were selected. It was revealed that the rational location of the distribution center ensures minimal transport work during the transportation of goods to any carrying capacity of the bicycle. To assess the effectiveness of an electric cargo bike, the amount of transport work performed using a battery capacity unit was used as a criterion. The value of this criterion is determined by the technical characteristics of the bike, namely carrying capacity, mileage on a single battery charge and battery capacity. The value of the efficiency criterion determined the ranks of bicycles taking into account technological parameters.
