【Abstract】 Some companies are moving to a distributed distribution system, in which each part of the final product is stocked separately and customer orders are fulfilled at a merge-center. Given that the transportation time is variable and the delivery time is a time window,we give two mathematical models to minimize the holding cost at the merge-center under timely delivery. Then we discuss how to solve the models to determine the transportation leadtime. Finally we present some discussions for the models.更多还原
