Inventory Control at Wheeled Coach
Controlling inventory is one of Wheeled Coach’s toughest problems. Operating according to a strategy of mass customization and responsiveness, management knows that success is dependent on tight inventory control. Anything else results in an inability to deliver promptly, chaos on the assembly line, and a huge inventory investment. Wheeled Coach finds that almost 50% of the cost of every ambulance it manufactures is purchased materials. A large proportion of that 50% is in chassis (purchased from Ford), aluminum (from Reynolds Metal), and plywood used for flooring and cabinetry construction (from local suppliers). Wheeled Coach tracks these A inventory items quite carefully, maintaining tight security/control and ordering carefully so as to maximize quantity discounts while minimizing on-hand stock. Because of long lead times and

Accurate bills of material (BOM) are a requirement if products are going to be built on time. Additionally, because of the custom nature of each vehicle, most orders are won only after a bidding process. Accurate BOMs are critical to cost estimation and the resulting bid. For these reasons, Collins was emphatic that Wheeled Coach maintain outstanding inventory control. The Global Company Profile featuring Wheeled Coach (which opens Chapter 14) provides further details about the ambulance inventory control and production process.

It supports collaborative planning, mandated cost and activity transfer to the suppliers, and automated replenishment. Collaborative planning and related information sharing with vendors are the prerequisites of VMI as in their absence, the supplier cannot have the visibility of production plan and therefore, cannot be expected to maintain and manage inventory in a blind situation of planning. Vendors are mandated to own the activity and costs related to management of inventory even at the buyer (MSIL) site. Automated replenishment system is the final objective of any VMI system, in which the execution against the replenishment strategy is done automatically through an IT- enabled system on the basis of daily changes in inventory and demand at the replenished site. For the VMI system to operate, Maruti needs to…arrow_forwardCaring Hospital’s dispensary reorders doses of a drug when the supply on hand falls to 18 units.Lead time for resupply is three days.
