D5 Annex WP 3: DATABASE METHODOLOGY AND DATABASE USER MANUAL – FREIGHT TRANSPORT DEMAND Figure D.1: Transportation of a computer manual cables mouse VAL A B C D E F G H I RoRo container In this figure we follow a computer from its place of production in point A to the consumer. The computer is transported by truck to point B where it is stuffed in a container together with other commodities. This container is transported by truck to point C where the truck goes on a ship to be transported to point D (Ro Ro). In point D the truck drives of the ship and goes to point E where the container is unloaded from the truck and stripped. The computer now is loaded on another truck to be transported to point F. In point F Value Added Logistics (VAL) takes place; the computer is put in another box together with additional features like cables, mouse and users manual. The computer is now transported to point G where it is transhipped on a train to be transported to point H. Finally it is transhipped again on a truck to be transported to point I. From a transport point of view the following problems relevant for the ETIS reference database development project can be identified in this fictional example: 154 Document2 27 May 2004
D5 Annex WP 3: DATABASE METHODOLOGY AND DATABASE USER MANUAL – FREIGHT TRANSPORT DEMAND 1. Who do we define to be the consumer of the computer?; which type of transhipment to include? 2. How to include simultaneous mode use in the database? 3. How to include loading units (containers, swap bodies) in the database? 4. Should there be a restriction on the number of links in a transport chain? Something that does not occur in the example is the case in which a container is empty. The following question can therefore be added: 5. How to include empty loading units flows in the database? These problems will be discussed in the following paragraphs. A way to a “pragmatic” approach of transport chains Who do we define to be the Consumer of the Computer?; which Type of Transhipment to include? The first question to be answered is whom we will define to be the customer. Another and more general way of looking at this problem is which type of transhipment we should include. If it has been decided which transhipment locations to include this implicitly means that also the production and consumption locations are defined. Several types of transhipment can be identified: 1. VAL (Value Added Logistics) 2. Distribution 3. Wholesale 4. Change of mode 5. Entrepot In our example VAL and change of mode can be identified. In the case of VAL a change of the characteristics of the commodities take place. The elements of this commodity that have to be considered the basic products find the end location at the VAL location while in fact they are transported in combination with the other basic products to another final location of consumption. In the computer example one of the basic products can even be given the same name as the final product. Distribution is another logistic phenomenon resulting in registration problems. Is the distribution centre the end point or just a transhipment location? Furthermore the transport from the distribution centre to the customers might be done with routing where different deliveries are combined into one trip, resulting in double countings in the database. For wholesale there is still another nuance. Here the commodity changes of owner, but is eventually transported to another location where it is consumed. Document2 27 May 2004 155
