Transport Basics...
A transport system comprises the elements of the goods transported (transport object), the means of transport used (mode of transport, traffic routes), and the transport process as an organized transport sequence (transport chain). The process of service provision results in transport services being carried out. Transport services cause movements of people or goods. We can distinguish between internal and external transport services. Internal transport services, for instance, occur within a plant among different departments of a warehouse. External transport services take place between suppliers and customers or between plants and warehouses. Transport processes carried out without actual goods being transported are referred to as empty transport. The criteria for a transport service are a providing location, a destination, and the goods transported. Goods are generally not manipulated during the transport process, i.e., merely the technical process of changing location takes place. The transport service performance is measured in tonne kilometers (tkm).
