ORIE 4580/5580 Homework Assignment 10 Due by Nov. 29, 11:00 am, in the drop-box located on the second floor of Rhodes Hall. 1. The customer service call-center of a small company has a single operator that works from 6 am until 6 pm. The customer calls arrive according to a Poisson process with mean inter-arrival time 180 seconds. The time to serve a customer call is exponentially distributed with mean 120 seconds. Each customer waiting in queue to talk to the operator has some patience duration and the customer hangs up without talking to the operator as soon as he runs out of patience. In this case, the call is lost. The patience duration of each customer is exponentially distributed with mean 400 seconds.

Unformatted text preview: a) Build a ProModel model to estimate the expected number of lost calls per day. Submit a text description of your model. Describe in two or three sentences of plain English how you modeled the patience behavior of the customers. (The customers who are still in the queue at 6:00 pm are also counted as lost.) b) Run your simulation model for 30 days and report a confidence interval for the expected number of lost calls per day. (Hint: This question requires some creativity. Your simulation model may not exactly model what physically happens in the real system, but it may still correctly estimate the performance measures of interest.)...
