Tailored Network
This is a combination of previousoptions that reduce the cost and
improves responsiveness of the
supply chain. The goal is to use the appropriate

The complexity of managing thistransportation network is high because
different shipping procedures are used
for each product and retail outlet,[email protected]

size)
Significant receiving expense
Direct shipping with milk
runs
Lower transportation costs for small lots
Lower inventories
Increased coordination
complexityAll shipments via central
