Call center data is processed by vendor-specific programs, in formats that are not amenable to operational analysis. Indeed, managers of large call centers argue that a 1-second increase/decrease in average service time can translate into additional/reduced operating costs on the order of millions of dollars per year. This type of model has the advantage of being simple and reasonably flexible, and can match the correlations between the arrival counts in different periods much better than previously proposed models. ll (Begin/End/Interqueue/Transfer/Outgoing/..). 0000002650 00000 n Complete the call center data modeling assignment we start in the Pre­class work and Activity 2 breakouts of Session 2.2. <>stream to Service Sciences, Engineering and Management. endobj Figure 2: Fate of a Call placed in the Interqueue, The first stage in pre-processing the data, is to, consist of segments of calls represented by a, output is a segment table, for each day, with, identification as well as a recoded segmen, The incoming calls that represent about 95% of customer calls are originated, outside the system (code 1), the inside cal, line key (code 4), the outgoing calls are or, outside the system (code 5), voice message, the message key (code 6).

Afshan Kinder, Winston Siegel, and Bruce Simpson are partners in SwitchGear Consulting, a company specializing in call centers and change management. We thus approximate the measures in an asymptotic regime known as QED (Quality & E-ciency Driven) or the Halfln-Whitt regime, which accomodates moderate to large call centers. ResearchGate has not been able to resolve any references for this publication. After obtaining the forecasted system load, in large call centers, a manager can choose to apply the QED (Quality-Efficiency Driven) regime's "square-root staffing" rule in order to balance the offered-load per server with the quality of service. Conditional on the number of calls in a period, their arrival times are independent and uniformly distributed over the period. 0000003766 00000 n This pre-processing involves transforming the data into a suitable form for the analysis. endobj A call segment record is constructed, for each leg of the call. Compu- tational results show that the robust fluid model is significantly more tractable as compared to the data-driven one and produces overall better solutions to call centers in most experiments.
