The purpose of this paper is to apply queuing theory to optimize wait times at a call center, as guided by the instructions and the case study provided by Srivastava (2016). Queuing theory provides a mathematical framework for analyzing waiting lines or queues, which is critical for optimizing service efficiency and customer satisfaction in call centers. The process involves modeling the call center’s operations, calculating key parameters such as arrival rate, service rate, and the number of servers, then applying these calculations to determine optimal staffing levels and expected wait times.

To begin, understanding the essential variables in queuing theory is crucial. The arrival rate (λ) refers to the average number of calls received per unit time, while the service rate (μ) indicates the average number of calls a server can handle per unit time. The number of servers (c) is the staff members available to handle calls. Using these variables, the utilization factor (ρ) can be calculated as ρ = λ / (c * μ). This represents the proportion of time the servers are busy. Maintaining a balance where ρ is less than 1 ensures the queue remains manageable and prevents excessive wait times.

In the case study, the original data and parameters were used to perform a baseline analysis. For this assignment, new values are introduced to develop an optimized model. These include different estimates of call arrival rates and service capacities, reflecting potential changes in call volume or staffing. The calculations involve employing formulas such as the Erlang C formula to determine the probability of wait, the average wait time in the queue, and the expected number of calls in line. Excel spreadsheets are used to model these variables at various stages, ensuring precise calculations and scenario analysis.

The key to optimization involves adjusting the number of servers (c) to minimize wait times while also considering cost implications. By increasing or decreasing staff levels, the model shows how wait times can be improved without unnecessary overstaffing. The goal is to identify a staffing configuration where customer wait times are minimized, and resource utilization is maximized effectively. These findings are critical for operational decision-making, especially during peak hours or unexpected call volume surges.

The final step in this process is the comprehensive analysis of the results derived from the Excel model, which includes several iterative calculations. The observations highlight the relationship between call volume, staffing levels, and wait times, providing actionable insights for call center management. Adjustments based on data-driven analysis lead to more efficient resource allocation, improved customer satisfaction, and operational cost savings.

This paper concludes by emphasizing the importance of queuing theory as a vital tool in call center operations, demonstrating how mathematical modeling facilitates enhanced decision-making and performance optimization. The approach used here exemplifies the practical application of operational analytics, supporting managers in developing strategies under variable demand conditions.
