For simple definition,logistics is a set of procedures in which commodity is delivered in an efficient manner from suppliers to customers.There are three key aspects to the concepts: 1.Movement of goods Goods can be considered as valuable objects,such as cargo and materials that are valua-ble and purchasable through commercial transactions and processes.Flow can be determined as methods in which goods are moved or transferred between locations,intermediaries and merchandisers.Modes of transportation include motor,rail,water,air and pipeline. 2.Direction of the flow of goods In the open market place,buyers and sellers represent two ends of a commercialtrans-action.Buyers are usually customers who demand the goods,while,as sellers are suppliers who provide such goods.When a transaction is agreed upon (sometimes payment is comple-ted,other times the payment is arranged to be completed at a later stage),the suppliers have the responsibility to arrange for the goods to be delivered to the customers. 3.Efficient management of the flow process The transportation of goods should bear low cost and ensure safety and punctuality.It should do its best to avoid wasting customers'resources.Currently,the flow of goods is generally controlled by both hardware and software.By hardware,we mean logistics facili-ties and equipment,such as ports,warehouses and trucks,ships,railroad,cars and air-lines.By software,we mean information system,standardization and data sharing.Questions:
