12. MRP at Wheeled Coach Video Case Wheied Couch, the woeld's laryest manufacturer of ambulapces, builk thousands of differcot and coastantly changing configurations of ba prodect. The cuntom nature of its business means lots of options and secial dexign - and a potential scheduling and inventory night mane, Wheled Coach addressed such problems, and succecded in wolving a lor of them, with an MRP system Idescribed in the Global Cevpovy Pryfie that opens this chapter). As with mos MIRP installa: bons, bowever, wolviag one set of problems uncovers a new set. One of the new fisues that had to be addresed by plant enanger Lynn Whalen was nealy discovered cuces inventory. Managers dis-covered a substantial amsouat of inventory that was not called for in any finishod products. Exces inventory was evident becaue of the new level of inventory accuracy required by the MRP system. The other rason was a sew series of isventory reports gencrated by the IBM MAFCS MRP sytem purchased by Whecled Coach. One of those reports inficates where ilems are used and is known as the "Where User repon. Interestingly, many inveritory items were not called out on bills of material (BOMs) for any current products. In some cases. the reaton some parts were in the stockroom femained a mystery, The discovery of this exces inventory led to renewed efforts to cosure that the BOMs were accurate. With substantial work, BOM acturacy increased and the number of engincering change notices (BCNs) decreased. Similarly, purchase-order accuracy, with regant te both part numbers and quantities ordered, was improved. Aditicnally. reciving departanent and dockroom accuracy went up, all helping to maintain schedule, costs, and uftimately, shipping dafes and quafisy. Eventually, Lyno Whien conclided that the residaal amounts of exess inventory were the resulf, at least in part, of rapid chasen in ambulance design and tectidelogy. Another source was castoner changer made after specifications had been determined and maten. als ordered. This latter excevs oxturs because, even thouph Wheciof Coach's owa throughput tine is only 17 days, many of the items that if purchase require much longer lead times. Discussion Questions* 1.
