11– 4. Basically, there are trade–offs between the cost of the physical distribution system, the service
level provided, and the sales achieved. There are also more specific trade–offs among
elements of the logistics system. For example, a better system for coordinating logistics
11– 5. There are a number of examples in the book that illustrate ways that coordination is taking
place and/or why it is important, so students should not have a lot of trouble coming up with
“hypothetical” answers. On the other hand, most students don’t have a very clear idea how
difficult it sometimes is for companies with different priorities, different philosophies, different
computer systems, and different cultures to work together for their common good. So, one
way to expand the thinking prompted by this question is to ask students what might get in the
way of the coordination actually occurring, or with it happening smoothly. If they seem to be
slow to come up with ideas, ask them to think about times when they have worked with a group
of people where it was difficult to get cooperation and then ask them if the same problems
might apply to relationships among whole firms.
11– 6. The use of computers (and other types of information technology) in the physical distribution
area are discussed throughout the chapter. Products are now stored in computer–controlled
warehouses and moved using automated conveyor systems. Computers are also being used
to keep track of inventory – and to order stock only when it is needed. EDI (electronic data
11– 7. A just–in–time delivery system can result in really big problems if there is a breakdown in
product quality – especially if products are not standardized (for example, different styles of
seats in different type of upholstery for different makes of automobiles on a production line). At
11– 8. It is no accident that firms that want just–in–time delivery systems prefer to work with suppliers
who are located close by. The greater the distance between the supplier and the customer,
the greater is the likelihood of some unexpected complication causing delays or irregularities in
deliveries. Such problems are likely to be magnified in international shipments, especially if
water transportation is involved. The long lead times required for water transportation make it
difficult to respond quickly to a change in customer needs. Further, problems can arise
because of a hold up in customs, with government red tape, etc.
