Logistics Management and Traffic Engineering
As a third-party logistics service, logistics management has many advantages in logistics distribution. The fields involved in logistics management and logistics are also constantly expanding, and logistics involves many disciplines, among which it is closely related to traffic engineering.
China's modern logistics industry is still in its initial stage of development and there is a big gap compared with developed countries. Logistics engineering is an interdisciplinary subject of management and technology. It is closely related to transportation engineering, management science and engineering, industrial engineering, computer technology, mechanical engineering, environmental engineering, architectural and civil engineering and other fields.
As a material production department, the transportation industry, like other material production departments, has experienced different development periods. In order to meet the needs of logistics management, five transportation modes have been formed: railway, highway, aviation, water transportation and pipeline. These modes of transportation have unity in meeting the requirements of people or objects' spatial displacement, namely, safety, rapidity, economy, convenience and comfort. However, the technical means adopted by various modes of transportation and the composition of the means of transportation are different. Therefore, the performance of the formed technology, the requirements for geographical conditions and economic indicators are not the same.
In the transportation cost and so on the comprehensive index consideration, if the unrelated expenditure proportion is larger, then the transportation cost is affected by the traffic density, the railway transportation is the most remarkable, the water transport, the road transportation is smaller, the transportation distance is longer, the road operation cost is low, therefore to the water transport the biggest impact, the water transport cost is lower. The railroad is second, the road is smallest. In addition, the size of traffic also affects transport costs, the largest capacity of transport vehicles, in general, its transport costs are low. Water transport is the first in this area. In general, transport and pipeline transportation costs are lowest, followed by rail and road transport, the highest cost of air transport.
Various modes of transport due to the different composition of the technical equipment, not only the total size of the investment varies, but also the investment period and the amount of initial investment is very different, various modes of transport in the line infrastructure investment and delivery are also different, water transport, air transport, the lowest line investment, the second road, pipelines and railways the highest, Railway technical equipment needs to invest a lot, manpower and material resources, investment is large and. The duration is long, so the investment is high-intensity. Comparatively speaking, the water transport is advantageous to the natural waterway, the line investment is far lower than the railroad, mainly concentrates in the wharf and the ship.
