There are two options for the leasing problem, buying at a high price or leasing at a low price. Once you choose to purchase the resources, you lose the opportunity to invest in other financial assets for additional benefits, such as a risk-free return of the interest rate. Thus, opportunity cost is an important factor to consider in the leasing problem. Accounting for opportunity cost, this paper extends the online leasing strategy for depreciable equipment. By applying competitive analysis, the optimal competitive ratios of the deterministic and randomized strategies are obtained. The results of numerical examples show that a smaller competitive ratio can be obtained when considering opportunity cost, which illustrates that the introduction of the opportunity cost has a significant influence on both the deterministic and randomized strategies.

租赁问题有两种选择，以高价购买或以低价租赁。一旦选择购买资源，便失去了投资其他金融资产以获得额外收益的机会，例如无风险的利率回报。因此，机会成本是租赁问题中要考虑的重要因素。考虑到机会成本，本文扩展了折旧设备的在线租赁策略。通过应用竞争分析，获得了确定性和随机策略的最优竞争比率。数值算例结果表明，考虑机会成本时，竞争比较小，这说明机会成本的引入对确定性策略和随机策略均具有重大影响。
