Beyond the functional aspect of the Speech service features, their primary purpose – when applied to the call center – is to improve the customer experience. . 144 0 obj The aim of the current, The raw data, as dumped by commercial call routing and recording systems, is not, e summary statistics that they supply are, For comparative and generic studies, it is im, aphs) has also been implemented and will be, database in practice involves considerably, tomated) mapping of raw input records into, tion codes – critical for classifying service, l times during the data collection period (30, system had to be set up in order to provide. linear basis model to approximate one generative model for each periodic force. role of measurements and data collection at the individual-call level is emphasized.

Glitch-Free Call Center Solutions Hosted on Fast and Secure Data Centers . 0000014671 00000 n It is one of the easiest ways to build a clear and structured model. call_end - time in seconds at which the call is ended.

We have chosen a typical day – Wednesday, April 2, 2002 – since this day is with, incoming calls. The model is applied to data from an Israeli Telecom company call center. modern call centres, simulation modelling is increasingly being used to predict their performance.

One of the most common is determining the weekly staffing levels to ensure customer satisfaction and meeting their needs while minimizing service costs. We propose both robust and data-driven approaches to a fluid model of call centers that incorpo- rates random arrival rates with abandonment to determine staff levels and dynamic routing policies.
