Choice of Transport Mode PlantWarehouse Inventory: 100.000 100.000 unit Price at Plant : $30/unit Carrying Cost : 30% of price/unit/year Transport Rate/R Transit Time/T Number of Mode ($/unit) (days) shipment/year Rail 0.10 21 10 Piggyback 0.15 14 20 Truck 0.20 5 20 Air 1.40 2 40 It is estimated that for every day that transit time can be reduced from the current 21 days, average inventory levels can be reduced by 1%, which mode to be selected if demand (D) was 700.000/year ? Transportation Management Senator Nur Bahagia@
Criteria Total cost = Inventory Cost + Transportation Cost • Plant • In-Transit • Warehouse • Transportation Cost (C.Trans) = R x D • In-Transit Inventory Cost (C.In-Trans)= ICDT/365 • Plant Inventory Cost (C.Plant) = ICQP/2 • Warehouse Inventory Cost (C.Ware) = IC’QW/2 • QP = 100.000/N IC = 0.3 x 30 • QW = 100.000/N IC’ = 0.3 x (30 +R) Transportation Management Senator Nur Bahagia@
