摘要: | 本研究以近年崛起的雲端運算服務產業為例,探討服務品質保證下之資源分配與定價策略。服務提供者藉由提供不同的服務合約類型以及訂定價格來區隔消費者市場並最大化自身的利潤,考慮提供兩種合約分別為高合約與低合約,合約具有不同的服務水準以及價格,並考慮該服務具有不同的服務層級協議(SLA: Service level agreement),也就是提供越好的服務所能得到的服務保證也就越好。基於服務層級協議,若服務提供者無法滿足客戶需求,也就是將資源分配給簽約客戶時,將會依照合約內容補償客戶合約價格的比例作為補償金。
本研究建立一個雲端服務資源定價的數學模式來描述不同的合約及不同的服務品質下的定價策略及獲利模式,並使用效用函式來評估客戶對於合約服務的滿意程度,作為選擇合約的參考依據。本研究找到該情境下的解析解,決定其最佳合約決策與定價策略,並提出數個論點與管理意涵。此外進行數值分析,探討在不同參數改變下會如何影響服務提供者之利潤與服務提供者所提供的服務,另外同樣考慮服務提供者在資訊對稱的情況下,所面臨的決策並作分析進行探討,本研究貢獻在於,在雲端運算服務中,有限的資源成為服務提供者的瓶頸,若能有效改善服務的品質並提升客戶對合約的信心,將能對服務提供者在利潤上具有相當大的幫助,並能有效改善服務品質與保證。此外利用合約品質與補償比例的差異化可以有效控制市場中的合約,明顯做出市場區隔以增加更多潛在客戶與利潤。 This paper studied the pricing strategy and the resource allocation with service guarantee in cloud computing service industry. In order to optimize the resource allocation and profit, the cloud computing service provider offers different services contracts with and pricing to segment customers. This paper consider two different contracts include premium and basic contracts with different SLA (service level agreement) and price. That is, better service accompany with greater service guarantee. According to different contracts, the penalty is applied to the service provider once SLA is not maintained. The penalty relate to contract price and unfulfilled resource. This research formulated a mathematical model to describe the profitability of the pricing model under a variety of resource availability and SLA. This research find some close-form solutions, which can help service provider to find optimal contracting and pricing. Besides, a numerical analysis was performed to investigate the impact of profitability under service provider’s decision and system parameters. The result reveals that the profitability is positively correlated with the higher service level and sufficient resource. The managerial implication for different contracting strategies is studied in this research. On the other hand, considering information symmetry for service provider and customers find other point of discussion. This research’s contribution is that improving service quality and compensation ratio are effect methods when the resource is bottleneck in cloud computing service. Service provider can offer both contracts simultaneously to enhance profit by price discrimination. |
