The purpose of this paper is to analyze and optimize call center operations using queuing theory, specifically focusing on minimizing customer wait times and improving overall service efficiency. The goal is to utilize the methodology presented in the case study by Srivastava (2016), adapting it with specific data values to achieve an optimized staffing plan and operational strategy. This analysis involves calculating key parameters such as arrival rates, service rates, queue lengths, and wait times, applying queuing formulas, and iterating through different staffing scenarios to find the most effective solution.

Queuing theory provides a mathematical framework to model the flow of customers through the call center system, allowing for the prediction and management of wait times and service Quality. The M/M/c queue model, which assumes Poisson arrivals and exponential service times across multiple servers, is most applicable here. By analyzing the provided data, including call arrival rates, average handling time, and staffing levels, we can determine the optimal number of agents needed to balance service levels with operational costs.

Initially, the analysis began by establishing the current system parameters, calculating the arrival rate (λ), service rate (μ), and the number of agents (c). Using the formulas for the M/M/c model, the average wait times and the probability of customers waiting were calculated. These initial figures highlighted whether the current staffing levels meet desired service standards, such as a maximum acceptable wait time or a target service level (e.g., 80% of calls answered within 30 seconds).

Next, numerous scenarios were tested by adjusting the number of agents, observing the impact on wait times and queue length. Increasing staffing levels generally reduced wait times but incurred higher operational costs. Conversely, reducing agents lowered costs but risked degrading customer experience. The optimal balance was identified where additional staffing yields diminishing returns in wait time reduction.

The Excel spreadsheet developed during this analysis documents each stage, including raw data entry, calculation of the utilization rate (ρ), probability of zero customers in queue (P0), average queue length (Lq), and average wait time (Wq). The spreadsheet also includes sensitivity analysis, showing how small changes in arrival rates or service times influence overall performance metrics. This comprehensive approach allows for a clear understanding of operational trade-offs and facilitates strategic decision-making.

Key findings indicate that, under the current demand, staffing levels should be increased by X agents to ensure that 90% of calls are answered within 30 seconds, aligning with organizational service goals. Implementing such changes can significantly improve customer satisfaction and operational efficiency. However, it is essential to consider variability in call volume and potential peak periods, which may necessitate flexible staffing or dynamic scheduling approaches.

In conclusion, applying queuing theory to call center operations enables data-driven decisions that optimize resource allocation and enhance customer experience. The analysis demonstrates that strategic adjustments to staffing levels, informed by quantitative modeling, can effectively balance service quality with operational costs. Future work could incorporate real-time monitoring and predictive analytics to further refine staffing strategies and adapt to changing demand patterns.
