By using operations research (OR), FedEx managed to survive crises that could drive it
out of business. The new planning system provided more flexibility in choosing the
destinations that it serves, the routes and the schedules. Improved schedules yielded into
faster and more reliable service. OR applied to this complex system with a lot of
interdependencies resulted in an efficient use of the assets. With the new system, FedEx
maintained a high load factor while being able to service in a reliable, flexible and
profitable manner. The model also enabled the company to foresee future risks and to
take measures against undesirable outcomes. The systematic approach has been effective
in convincing investors and employees about the benefits of the changes. Consequently,
"today FedEx is one of the nation's largest integrated, multi-conveyance freight carriers"
