将连续使用设备的单阶段在线租赁推广到间隔使用设备的两阶段在线租赁,给出两阶段在线租赁的竞争策略及其竞争比上界。进一步解决可折旧设备两阶段的在线租赁问题,使得问题更加贴近实际租赁问题,从而为大型设备投资者提供更好的决策依据。通过数值实例说明两阶段租赁竞争比小于剔除间隔后的单阶段租赁竞争比,进而验证结果的有效性和可行性。
The single-phase online leasing of continuous-use equipment is extended to the two-phase online leasing of interval-use equipment, and the competitive strategy of two-stage online leasing and its competitive upper bound are given. To further solve the two-phase online leasing problem of depreciable equipment, the problem is brought closer to the actual leasing problem so as to provide a better decision-making basis for large equipment investors. The numerical example shows that the competition ratio of two-stage lease is less than the single-stage lease competition ratio after the elimination interval, and the validity and feasibility of the results are verified.
