3.5 Enhancing forewarning of demand
It is desirable to get as much forewarning as possible of customer's demand to be able to bring the logistics lead time as close to it as possible. There are two ways of doing this:
- Get information on customer needs faster, before orders are placed.
- Understand reorder points of customers, to pre-empt orders.
EPOS. This is seen to work very efficiently in various supermarkets where electronic point of sale (EPOS) systems are installed. The electronic till is linked to the inventory level and sensitive data monitoring identifies customer behaviour. If articles are being purchased faster than normal, reorder points are adjusted to prevent stock out situations. Getting such information allows the supplier to be prepared for changes in orders and be able to source supplies in time. Buyers and sellers both gain form the exchange of such knowledge. The logistics system becomes much more responsive. Markets are becoming more time and price sensitive. Both sides of the demand have to be addressed - not just cheaper but also quicker!
ERP. A more recent development has been the emergence of enterprise resource planning (ERP). This system records all transactions, produces and executes orders and follows payments. In other words, it can schedule all procurement and distribution activities. ERP is based on computing and IT for data collection and information processing. The databases required for making the best use of the potential of ERP are enormous. Organisation-wide computing and data collecting functions are linked into the system and this data can be shared with suppliers and customers.
One of the perceived shortcomings of ERP is that it can get too accounting oriented, that is, companies can get too focused on the savings in money terms rather than on wider improvements of operations. In addition, ERP packages are often customised for specific organisations. This has a cost attached to it, although the resulting savings may far exceed this initial cost. The personnel who use this system will have to be suitably trained as well.
The next reading gives an example of another program, Virtual Direct, that is used in this case study of Xilinx.

As abilities of computing and applications increase, some of the shortcomings of ERP are being addressed. New chapters like advanced planning and scheduling (APS) that are based on very powerful computer applications optimise scheduling and planning functions. While APS systems can be integrated with all the functions of logistics that we have discussed so far, they can also be used to manage inventory, making them a total logistics application. While the systems continue to grow in their abilities and applications, they are also getting very complex and call for considerable skill form operators and planners.
