The main features of modern transportation management automobiles

Hello, the important content of the use of vehicles 1) China's railway passenger cars implement a fixed distribution system, and the daily maintenance is responsible for the passenger station and train inspection of the depot. (2) Trucks pass through the whole wheel, except for special vehicles and special trains, generally do not implement the subordinate system, but implement the national railway maintenance responsibility system according to the section. The maintenance of the assigned goods vehicles is carried out by the assigned or designated depot (vehicle factory) or the inspection office.

Due to the large number of trucks, the complexity of the models, the poor application conditions, and the passage of the whole country, the maintenance site is scattered, and the technical inspection operation time is tight, so the task of vehicle maintenance work is arduous and the responsibility is heavy. The inspection and maintenance work in the operation of the truck is uninterrupted day and night in the open air, and the working conditions of the workers are difficult. Due to the rapid development of China's railways, the application and promotion of railway modernization technologies such as heavy load, speed increase and information technology have made the use of trains more technical.

The main tasks include: (1) studying and analyzing the change law of automobile performance under operating conditions; (2) Research, design and trial production of modern test chamber principles, methods and test devices for automobiles and engines; (3) Research and design the technology and procedures for the diagnosis of automobile dust, optimize and design the programs and procedures for eliminating automobile faults, and develop, design and trial produce instruments and devices for automobile fault diagnosis and elimination; (4) Research and design of automobile maintenance and repair technology, research, design and manufacture of process chain equipment and tools.

The technical and economic characteristics of the number of transportation modes: Railway: large transportation capacity, fast running speed, low transportation cost, good transportation regularity, low energy consumption, good versatility, poor mobility, large investment, long construction period, and large land occupation.

Roads: flexible and flexible, easy training of drivers, simple packaging, less damage to goods, high transportation costs, small transportation capacity, more land occupation, low labor productivity, high energy consumption, serious environmental pollution Waterways: large transportation capacity, low energy consumption, low transportation costs, less construction investment, less land occupation, high labor productivity, long average transportation distance, slow transportation speed, greatly affected by natural conditions, poor accessibility Aviation:

High-speed accessibility, high safety and jujube annihilation, unique economic value, low packaging requirements, small carrying capacity, large investment, high cost, susceptibility to climatic conditions, poor mobility Pipeline: small transportation volume, short construction period, low investment cost, small land occupation, in line with green transportation requirements, low energy consumption, low cost, good transportation regularity, poor flexibility The concept of transportation rationalization: refers to the shortest mileage in accordance with the law of commodity circulation, transportation conditions, reasonable flow of goods, market demand, the shortest mileage, and the most suitable capacity through the least links, spend the lowest cost, and transport goods from the place of production to the place of consumption as quickly as possible Impact Factor:

Transportation distance, links, tools, time, cost Unreasonable transportation situation: empty driving, convection transportation, reverse transportation, roundabout transportation, too far transportation, repeated transportation, invalid transportation, improper selection of capacity, improper selection of consignment mode Reasonable transportation: reasonable selection of transportation methods, tools, correct selection of transportation routes, improve the quality of cargo packaging and improve packaging methods in distribution, mixed distribution to reduce capacity input, the use of large-tonnage transportation, the development of socialized transportation system, the development of direct transportation, Advocate combined vehicle transportation and make full use of the loading capacity of the means of transport What are the main components of the cargo transportation system:

It mainly includes the goods market, service objects, business entities, freight infrastructure, mobile facilities, and organizational and management means. Types of specific organizational forms of cargo transportation business: 1. The direct consignment system of the cargo owner, which refers to the transportation business organization system in which the consignment and carrier relationship directly occurs between the cargo owner and the transport enterprise that masters the means of transport 2

It refers to the transportation business system in which the consignment and carrier relationship is established between the cargo owner and the transportation contractor, and the transportation shed is organized by the contractor to realize the chain rough lease and the cargo transportation process. Container cargo flow is based on the size of its sending and receiving volume and its choice of four transportation organization forms: large volume and small volume (FCL loading, FCL cargo dismantling).

Large volume and small amount of receipt (FCL loading, LCL unpacking). The volume of issuance is small and the amount of receipt is large (LCL loading, FCL unpacking). Small volume and large amount of collection (LCL loading, LCL unpacking.
