MRP at Wheeled Coach
Major Issues at Wheeled Coach
Why does Wheeled Coach used MRP?
Wheeled Coach has four key tasks be performed
Twelve major ambulance designs are produced on assembly lines.
18,000 different inventory items in which 12,000 purchased.
Most of the product line is custom designed and assembled to meet the specific requirements demanded by customer preference
A dependent demand technique that uses a bill-of-material, inventory, expected receipts, and a master production schedule to determine material requirements
Master production schedule
Bill of material
Purchase orders outstanding
Better response to customer orders because of improved schedules
Faster response to market changes
Improved utilization of facilities and labor
Reduced inventory levels
The material plan must meet both the requirements of the master schedule and the capabilities of the production facility.
The plan must be executed as designed.
Inventory must be minimized through effective "time-phased" material deliveries, and a constant review of purchase methods.
Excellent record accuracy is a fundamental ingredient of Wheeled Coach's successful MRP program that not only correct errors but also investigate and correct problems.

• Some items were in inventory because of customer changes in specification after orders were place.

3. purchasing and receiving errors
• Cycle Counting
• Sell excess items
