Unformatted text preview: Douglass Campus Takeout Modeling and Improvements Submitted by: Farrah Vijayan Nikita Dhillon Lina Truong December 20, 2010 Probabilistic Models of Operations Research Professor Melike Gursoy 14:540:338, Sec. 01 EXECUTIVE SUMMARY The system analyzed through this report is the queuing process of the Neilson Dining Hall Take Out, on the Cook/Douglass Campus of Rutgers University. Throughout this paper, we analyze the queuing process that is presently used, and discuss a method to improve the efficiency by decreasing the overall waiting time that each individual student faces. Various observations were taken in order to attain actual numbers for the average time spent by customers in the system. With this data, we produced the Arrival Rate and the Service Rate, enabling us to calculate the average time a student spends in the system. The queuing discipline is FCFS (First Come First Serve), which entails that the customers are served in order of their arrival. To model this system we used an M/M/1 queuing system, meaning that both inter arrival times and service times are exponential. Furthermore, it is a series service process, with all employees working simultaneously to provide food. The arrival process is unaffected by the customers present. Under these assumptions, we calculated the waiting times for each student. Through our analysis of all relevant factors, we determined a method to increase the efficiency of the process by changing the queuing system. By doing so, we determined a waiting time that is substantially smaller than the one students currently experience. These changes are discussed in detail thoroughly in the paper.
