Forecasting Arrivals to a Telephone Call Center
Accurate forecasting of call arrivals is critical for staffing and scheduling of a telephone call center. We develop methods for day-to-day and dynamic within-day forecasting of incoming call volumes. Our approach is to treat the intra-day call volume profiles as a highdimensional vector time series. We propose to first reduce the dimensionality by singular value decomposition of the matrix of ...
متن کاملForecasting Call Center Arrivals: a Comparative Study
We evaluate alternative time series methods for forecasting future call volumes in call centers. Our methods take into account both interday (day-to-day) and intraday (within day) dependence structures, and allow for real-time dynamic updates. We also propose a new model which exploits correlations between the arrival processes of two separate queues, leading to more accurate forecasts. We desc...
متن کاملModeling Daily Arrivals to a Telephone Call Center
W develop stochastic models of time-dependent arrivals, with focus on the application to call centers. Our models reproduce three essential features of call center arrivals observed in recent empirical studies: a variance larger than the mean for the number of arrivals in any given time interval, a time-varying arrival intensity over the course of a day, and nonzero correlation between the arri...
متن کاملScheduling Agents Using Forecast Call Arrivals at Hydro-Québec's Call Centers
The call center managers at Hydro-Québec (HQ) need to deliver both low operating costs and high service quality. Their task is especially difficult because they need to handle a large workforce (more than 500 employees) while satisfying an incoming demand that is typically both time-varying and uncertain. The current techniques for determining the schedule of each employee according to the fore...
متن کاملModeling and Forecasting Call Center Arrivals: a Literature Survey
The effective management of call centers is a challenging task mainly because managers are consistently facing considerable uncertainty. Among important sources of uncertainty are call arrival rates which are typically time-varying, stochastic, dependent across time periods and across call types, and often affected by external events. Accurately modeling and forecasting future call arrival volu...
