The methods considered include seasonal autoregressive integrated moving average ARIMA modeling; periodic autoregressive modeling; an extension of Holt-Winters exponential smoothing for the case of two seasonal cycles; robust exponential smoothing based on exponentially weighted least absolute deviations regression; and dynamic harmonic regression, which is a form of unobserved component state-space modeling.

A notable feature of these series is the presence of both an intraweek and an intraday seasonal cycle. Predictions of call center arrivals are a key input to staff scheduling models. This allows to link your profile to this item.

We analyze five series of intraday arrivals for call centers operated by a ecnter bank in the United Kingdom. Jackson, Emerson Abraham, Mirko Janc The email address of this maintainer does not seem to be valid anymore. Kim, Myung Suk, You can help correct errors and omissions.

It is, therefore, surprising that simplistic forecasting methods dominate practice, and that the research literature on forecasting arrivals is so small.

A Comparison of Univariate Time Series Methods for Forecasting Intraday Arrivals at a Call Center

We find a similar ranking of methods for call center data from an Israeli bank. Our results indicate strong potential for the use of seasonal ARIMA modeling and the extension of Holt-Winters for predicting up to about two to three days ahead and that, for longer lead times, a simplistic historical average is difficult to beat.
