LOGISTICS MANAGEMENT An important feature of Wal-Mart’s logistics infrastructure was its fast and responsive transportation system. The distribution centers were serviced by more than 3,500 company owned trucks. These dedicated truck fleets allowed the company to ship goods from the distribution centers to the stores within two days and replenish the store shelves twice a week. The truck fleet was the visible link between the stores and distribution centers. Wal-Mart believed that it needed drivers who were committed and dedicated to customer service. The company hired only experienced drivers who had driven more than 300,000 accident-free miles, with no major traffic violation.
Wal-Mart truck drivers generally moved the merchandise-loaded trailers from Wal-Mart distribution centers to the retail stores serviced by each distribution center. These retail stores were considered as customers by the distribution centers. The drivers had to report their hours of service to a coordinator daily. The coordinator scheduled all dispatches depending on the available driving time and the estimated time for travel between the distribution centers and the retail stores. The coordinator informed the driver of his dispatches, either on the driver’s arrival at the distribution center or on his return to the distribution center from the retail store. The driver was usually expected to take a loaded truck trailer from the distribution center to the retail store and return back with an empty trailer. He had to dispatch a loaded truck trailer at the retail store and spend the night there. A driver had to bring the trailer at the dock of a store only at its scheduled unloading time, no matter when he arrived at the store. The drivers delivered the trailers in the afternoon and evening hours and they would be unloaded at the store at nights. There was a gap of two hours between unloading of each trailer. For instance, if a store received three trailers, the first one would be unloaded at midnight (12 AM), the second one would be unloaded at 2 AM and the third one at 4 AM.
