Sloan, Yeu-San Tee, Mee-Ching Chow
Problem Determine pre-positioning strategies
for supplying Pacific Rim sites that can
simultaneously meet desired service and cost
levels.
Objective Develop transportation and inventory
models to optimize DLAs inventory decisions for
the Pacific Rim.
31
Methodology/Conclusion
Methodology
Phase 1 Evaluation of pre-existing software
(ShipCost) for use in the analysis of DLAs
shipping options. Development of ShipRoutes
spreadsheet application for DLAs logistics
network in the Pacific Rim. Based on the same
cost models as ShipCost, it calculates total
transportation cost and time for all modal
combinations for a route. Phase 2 Discovery and
evaluation of multi-echelon inventory models and
spreadsheets appropriate to DLAs inventory
system, considering meeting customer service
requirements at the least cost for
transportation, ordering, and inventory.
Conclusion Lack of real data precluded testing
the models developed by U of A.
