This paper revisits the airline schedule-buffer choice problem analyzed by Brueckner et al. (2021) using a simpler model where the random shocks influencing flight times are discrete rather than continuous. The analysis yields closed-form solutions for the flight and ground buffers as well as full comparative-static results, neither of which were available in the earlier paper. The paper also explores several extensions to the model that were not present in the previous paper.

航空公司时刻表缓冲和航班延误：离散模型

本文重新审视了 Brueckner 等人分析的航空公司时刻表缓冲选择问题。(2021) 使用更简单的模型，其中影响飞行时间的随机冲击是离散的而不是连续的。分析产生了飞行和地面缓冲区的封闭形式的解决方案以及完整的比较静态结果，这两个结果在早期的论文中都没有。该论文还探讨了该模型的几个扩展，这些扩展在之前的论文中没有出现。
