Lewelling Date February 13, 2002 1. Customers
arrive at the Lake Gardens post ofice for buying
stamps, mailing letters and packages, and so
forth. The interarrival time is exponentially
distributed with a mean of 2 minutes. The time
to process each customer is normally distributed
with a mean of 10 minutes and a standard
deviation of 2 minutes. How many postal clerks
are needed at the counter so that there are no
more than 15 customers waiting in the post office
at any time? Make a time series plot of the
number of customers in the post office in a
typical eight-hour day. Change the number of
postal clerks until you find the optimum number.
Five postal clerks are required so that there are
no more than 15 customers waiting in the post
office at a time.
2. The Lake Gardens postmaster in Exercise 1
wants to serve his customers well. He wold like
to see that no postal customer has to wait more
than 15 minutes a the post office. Make a graph
for the content histogram for the cycle time in
the system. 3. For the example in Lab 3, Section
L3.3, find out the percentage of time the
splitter and the lathe are idle. Make a state
graph and a pie graph for these locations.
Splitter - 5.33 Lathe - 16.76
4. For the example in Lab3, Section L3.2, plot
the time painted logs spend in the manufacturing
facility. Also, plot the number of painted logs
produced.
