Treatment of Serviceable Returns in Supply Control Studies

摘要

Currently, because the forecast of serviceable returns is not trusted, the use of these returns as an offset to the demand forecast is limited. Various options for incorporating serviceable returns into the demand forecast were evaluated based on a cost/performance inventory measure. A forecast which offsets returns will cost less, but will also result in a lower supply performance. Our findings show that adjusting the demand forecast by returns has the same effect as not offsetting the demands with returns but lowering the performance goal. In either case, the change in cost and the change in supply performance are virtually identical. (Author)
