What are the three main categories of logistics information systems? What function does each serve?

What will be an ideal response?


Answer: Logistics information systems fall into three major categories: decision support tools, planning systems, and execution systems.
Logistics managers often use decision support tools to design and fine-tune their logistics systems. Such tools help managers choose locations for their warehouses, determine the number of containers or vessels they need, and estimate costs and travel times. Some decision support tools even have simulation and optimization capabilities.
Planning systems help managers with specific activities, such as selecting a carrier for an outgoing shipment or developing a weekly schedule of deliveries. Of course, such activities have been going on for a long time. But with the aid of computer-based planning systems, today's logistics managers can more quickly analyze a wider range of options and identify the delivery schedule or carrier that best suits their needs.
Execution systems are the most detailed level of a logistics information system. As the name implies, execution systems take care of the hundreds of small details associated with logistics activities, ensuring that planned activities take place as expected. They oversee order and shipment management, shipper/receiver management, satellite and bar code tracking, and automated payment and billing systems. Execution systems can also help managers monitor the logistics system and identify problems before they get out of hand.
