A bilevel model for transportation service sharing in Supply Hub in Industrial Park (SHIP)

摘要

Supply Hub in Industrial Park (SHIP) can provide transportation service sharing by dispatching a vehicle to circulate multiple manufacturers to cover their delivery requirements. This paper discusses how Supply Hub in Industrial Park (SHIP) and manufacturers interact to optimize their decisions on transportation pricing and milk-run cycle time, and the delivery schedules of raw materials. This problem is modeled as a bilevel program with the SHIP as the leader and manufacturers as followers. A numerical study is conducted to examine the influence of major parameters.
