Abstract
In most sectors of the national economy, technical facilities are represented by unloading devices that extract bulk cargo from the freight rolling stock, store it for a certain time, and ship it to a similar or other type of transport. Objects intended for the implementation of the stages of loading, unloading, and various storage periods, including bulk cargos, are commonly referred to by the broad scientific community as transport and warehouse complexes (TWC). Most operations performed in the TWC are the movement of goods (internal movements, receiving or sending goods by various modes of transport. The authors clarified the concept of "transport and warehouse complex" - it is an element of the transport network of the region, providing communication of external transport systems of the regions and performing the functions of converting the cargo flow of the region into the cargo flow sent by the region. On the one hand, they perform functions of transshipment points in relation to deep (economic) warehouses, and on the other – the functions of storage facilities. Their primary purpose is determined and depends on a large number of factors, including: the size of the direct service area, the ratio of the design capacity of the warehouse to the volumes of deliveries and the use of bulk cargo, as well as the condition of roads in the serviced area, the uniformity of the receipt of bulk cargo and the availability of vehicles for their delivery to the consumer.
Highlights
Ensuring a stable discharge of bulk cargo is largely due to a complex of factors of mutual influence of the set of material properties and parameters of the container intended for storage (Al Alaween, et al 2020)
The quality characteristics of the storage facility for bulk cargos should be used in the development, production and operation for the implementation of tasks:
The authors created a mathematical model of a complex indicator for assessing the quality of bin storage facilities, justified individual criteria for the design parameters of bin-type storage facilities, taking into account the physical and mechanical properties of bulk cargos, and proposed a method for a comprehensive assessment of the operation of bins (Goryushinsky, et al 2003; Tretyakov, et al 2010)
Summary
Ensuring a stable discharge of bulk cargo is largely due to a complex of factors of mutual influence of the set of material properties and parameters of the container intended for storage (Al Alaween, et al 2020). The modern selection of geometric parameters of bins in the vast majority of cases is based on the previous work of the designer or the search for standard schemes of bulk storage with similar operating conditions is carried out, adapting them to the dimensions of specific industrial buildings. The set of individual properties of a certain bulk cargo, and, the guarantees of uninterrupted unloading, are not fully taken into account in the design works on the bins. The magistral and industrial transport of the regions is characterized by the creation of equal conditions for production, storage facilities, which is its feature (Rychkov, 2001). The main link between transport routes is the hub center, which provides the regions with means of transportation for loading manufactured products or unloading and placing goods used as material for processing
