Question 2: Scheduling problem
(12 points, Module 7, part 7.2)
This study analyzes how a buying agent serves as an export-import link between the manufacturer of
Asian goods and the retail companies in the West. The agent needs to ship fashion and seasonal
apparel from Location A (Singapore) to Location B (Vancouver, Canada). The product orders are
shipped from a distribution center in Hong Kong through water transportation modes.
The manager of the buying agent in Location A (Singapore) must commit to shipyard (seaport)
deadlines (date and time) for the order shipment. The procurement from local manufacturers in
Location A are maintained to accommodate the shipping schedule, which ultimately confirms the
due dates assigned by the retail companies at the location B (Vancouver, Canada). If the orders miss
their scheduled dates to reach the shipyard (seaport) by a day or few hours shipping cannot be
guaranteed. Once a shipment schedule is missed, it may take 2-10 businesses days to get the next
scheduled shipping date. Therefore, the agent informs the cut off days to the area manufacturers
based on the best shipping schedule that minimizes the shipping cost while maintaining the
designated due dates set by the retail companies.
The cost ($) of products is wire transferred to the Agent upon receiving the product. Therefore,
some indirect holding (carrying) cost incurs during the shipment lead time period. If a shipping date
is missed, this leads to additional holding cost as well as the risk of missing the retailers due date.
The cut-off dates are considered the most sensitive issues to minimize shipping cost and business
Assuming that the cut-off dates are maintained, the Agent must choose between two shipping
companies and four alternatives. Suppose the agent ships 20 different products, a total of two
million items per month, which requires about 300 containers. The shipments lead time between
seaports in Location A to seaport in Location B requires 22-25 days for standard shipping and 30-32
days for basic shipping and handling.
