Customers enter the camera department of a store at an average rate of five per hour. The department is staffed by one employee, who takes an average of 8.0 minutes to serve each arrival. Assume this is a simple Poisson arrival, exponentially distributed service time situation. (Use the Excel spreadsheet Queue Models.) a-1. As a casual observer, how many people would you expect to see in the camera department (excluding the clerk)? (Round your answer to 2 decimal places.) a-2....
Customers enter the camera department of a store with an average of 14.46 minutes between customers. The department is staffed by one employee, who can handle an average of 11.76 customers per hour. Assume this is a simple Poisson arrival, exponentially distributed service time situation. Find the following information to help the manager decide if a second employee should be added: 1) The average number of customers waiting.

The service counter is staffed by only one clerk, Judy Gumshoes, who works eight hours per day. Assume Poisson arrivals and exponential service times. a. What percentage of time is Judy idle? (Round your answer to 1 decimal place.) Percentage of time --------------% b. How much time, on average, does a student spend waiting...
PA 7-10 Aquatica makes underwater camera housings Aquatica makes underwater camera housings for divers. The prooass begins with a solid rectangular block of aluminum which is used to make a single housing. A Computer Numerically Controlled (CNC) machine drills into the block to make the metal frame of the housing. Each block requires 15 minutes of drilling. The frame is then chemically treatad in a seres of baths. There is ample capacity in the treating stage. Finaly, a worker must...
