Technical Note—Approximating Systems Fed by Poisson Processes with Rapidly Changing Arrival Rates
针对到达率快速波动的非平稳系统,提出了一种通用、封闭且简单的近似工具,帮助运营管理者在非平稳环境下进行性能预测和决策。
In many operations management settings, the arrival process to the system exhibits clear nonstationarities. These nonstationarities may arise as a consequence of time-of-day effects, day-of-week effects, seasonalities, or stochastic fluctuations in the arrival rate. Tools that are developed for performance prediction and decision making when systems are stationary may not be valid in the nonstationary environment. This paper provides a generic, closed-form, and simple approximation tool for when the nonstationarities are caused by rapid fluctuations in the arrival processes.
