本篇論文描述影片出租業面臨一個狀況，就是必須去決定最佳的新片庫存水準跟新片上架期間使得通路利潤最大化。我們考慮部分影片在新片出租期間結束會被以二手片出售。另外，我們假設每隻片子的租期為已知。為了滿足影片的出租需求跟還片過程會隨著時間的變化，本研究將提出一個基本的數學模型去描述新片的庫存水準跟出租期間長度的訂定會如何去影響影片出租業的利潤。接著我們將會把基本模型擴充，即導入營收分享契約並說明它如何影響新片出租期間跟庫存水準。同時探討營收分享契約如何改變通路的績效與是否能夠讓所有通路成員獲利都提升。 本研究將採用自己發展的演算法去求得基本模型與擴充模型中最佳的期初庫存水準、新片出租期間與營收分享係數以最大化整個供應鏈的利潤。 我們將提供數值實驗的分析去探討營收分享契約對於整個通路利潤的影響與是否能使供應鏈中的成員達成雙贏的局面並最佳化通路利潤。最後，我們將針對一些重要的參數去作敏感度分析，希望得到一些對本論文有幫助的管理意涵。 This study exploits a problem faced by a video rental shop when jointly determining the optimal stocking level of a new tape and the optimal length of time of a new tape exhibition. Some videotapes will be sold as secondhand tapes for salvage at the end of new tape rental period. Besides, a retailer that rents tapes to customers for a pre-specified rental duration. To meet the time-varying rental demand and return process, we first propose a basic model that is intended to analyze the impact of the stocking level and new tape rental period on the retailer’s profit. We next extend our basic model to the case in which a retailer implements a revenue–sharing (R-S) contract with a supplier. In the extended model, we illustrate how revenue sharing influences new tape rental period and stocking level. Moreover, we demonstrate how it alters the performance of a supply chain and investigate whether the R-S contract can result in larger profits for all firms or not. In this study we adopt an algorithm that we develop to decide the optimal initial purchasing quantity, the new tape rental period and the coefficient of R-S contract to maximize the supply chain’s profit under the basic model and the extended model. We also provide numerical analysis to investigate the impact of the R-S contract on channel’s profit and study whether the R-S contract can achieve the win-win conditions or not. Furthermore, we will show that R-S contract can optimize the channel’s profit and bring win-win situations to the players in the industry. Finally, we study the effects of the particular parameters and conduct the sensitivity analysis. We hope the experimental result can generate interesting managerial insights regarding the relative importance of the parameters.
