# Comparison of the Relative Importance of Factors Affecting the Conveyance of Bulk and Liquid Cargo
## 1 Introduction
Lightweight nets have the potential to serve as suitable coverings for open trucks and containers that do not necessitate a more substantial enclosure. It is imperative to emphasize the importance of ensuring the integrity of the metal components of the nets, as they should be free from any signs of damage or corrosion. Additionally, it is crucial to ascertain that the net remains intact without any cuts, and that all seams are in optimal shape. Semi-trailer awning is considered to be the most secure and durable method for safeguarding large quantities of cargo. The parapulin is secured to the sides of the tipper using fastening mechanisms. This method of preparing the vehicle serves to shield the bulk cargo from the impact of atmospheric conditions, ensuring that the cargo remains unaffected in terms of its physical and mechanical characteristics. Bulk materials are used in industrial and agricultural production, but their interaction with structures can cause structural wear and dust pollution. A multiphase data fusion simulation approach is proposed for discrete material transfer dispatch in digital twin systems. The Discrete Element Method (DEM) is used to obtain bulk material movement and force data on structures, accurately calculating force data using the Finite Element Method (FEM). This method helps predict structure wear and manage the operating environment [15]. The enhancement of bulk freight transportation efficiency can be achieved by the establishment of technical standards pertaining to the loading of cargo into wagons. Different methods of transporting bulk cargo over railways, such as utilizing bags and big-bags, have been suggested as a means to enhance the capacity of wagon loads. A rationale is needed for selecting a specific style of wagon for the transportation of bulk products via road transport, drawing upon established approaches for efficient freight transportation. Recommendations play a crucial role in the selection of appropriate vehicle types and the optimization of carrying capacity based on transportation conditions, hence enhancing the efficiency of bulk freight transportation [16]. Liquid bulk and gaseous cargoes are types of cargoes that necessitate the utilization of specialized containers for their transportation and storage. The aforementioned items include glass containers, metal containers, and a variety of balloons. The magnitudes of these loads are determined using calculations that consider either their volume or mass. Bulk liquid cargoes refer to substances that possess the capability to be efficiently loaded and unloaded via pipelines, as well as stored and transported within tanks. A range of cargoes, including fuels, water, liquefied gases, and non-liquefied gases, might be associated with this category. For instance, the transfer of liquid items is a domain of cargo transportation that necessitates both specialized transportation and meticulous preparation. To mitigate the risk of tipping, which poses a significant hazard to transportation safety, the tanks are partitioned into several portions. Each portion is designed with a graduated capacity of 2000 L. Initially, one section is occupied, followed by another, and ultimately the remaining sections are filled. In order to promote secure transportation, it is recommended that the sections be filled to a maximum capacity of 80%, as this practice effectively mitigates the risk of spilling. The analysis of data pertaining to tank trucks carrying hazardous liquids is necessary to enhance safety measures. The research aims to identify eight elements that have a substantial influence on the frequency of accidents, with particular focus on the inherent safety characteristics of vehicles [17]. Researchers have focused on accident risk assessment in hazardous chemicals road transport accidents, analyzing data from China over the past five years. They used a Bayesian network structure and parameter learning to predict the risk probability value of accidents.
