考慮保固期及最終訂購量下建構銷售利潤最佳化模式─以筆記型電腦為例
Development of sales profit optimization model with the consideration of warranty and final order – a case study on notebook computer
摘要
目前筆記型電腦產業產品生命週期短，導致在產品生命週期結束之後，業者對於產品損壞置換之備品量─即為最終訂購量，往往發生存量過多或不足的情況。再者，產品保固期已成為銷售不可缺的利器之ㄧ，但業者因提供保固期後，產品因置換或增加預留存貨的成本，將會增加業者負擔。除保固期外，售價亦會影響銷售量高低，售價過高會導致銷售量下降；反之，則上升。因此銷售量會同時受到保固期及售價的影響而形成權衡的現象。 本研究根據售價及保固期的權衡現象發展利潤最佳化模式，找出產品生命週期中每一期利潤最佳化下之保固期及售價，並根據每一期之銷售量找出產品生命週期結束時，所需準備之最終訂購量。另外在本模式中同時考量筆記型電腦共用零件之特性，討論因零件共用時，找出最適的最終訂購量。

Due to short product life cycle (PLC) in the notebook computer industry, manufacturers or branders need to prepare enough quantity of spare parts for repairs or replacements after the PLC, which is the final order. But very often, the inventory of spare parts is not enough or too much, which causes losses. In these days, longer product warranty length can attract more people to buy the product, but it will cause more burdens to keep more quantities of spare parts for manufacturers or branders. In addition, the sale price is also an important factor to affect the sales volume. Therefore, there is a trade-off phenomenon between warranty and price for sales volume. In this study, we develop a mathematical model that includes two steps; one is to develop a profit optimization model that considers the trade-off phenomenon between warranty and price in order to find the best warranty, price and sales volume in product life cycle; the other is to calculate the final order after PLC based on the sales volume within the PLC and warranty length. Moreover, this study explores the effect of common key components used in different notebook computers in order to find the better final order.
