Consider a machine that has a natural process time of 1 minute(deterministic) when it works but is subject to failures withMTTF=100 minutes and MTTR=10 minutes. Assumecr=1. This machine receives parts every 1.5minutes from the previous process (deterministic).
a. What is the availability of thismachine?
   Â
b. What is the average effectiveprocess time, te, for this machine?
c. What is the squared coefficient ofvariation of the process time,ce2?
d. How long does the average partwait in queue in front of this machine before being served?
Suppose you are observing parts come out of this machine.
e. What is the average rate withwhich parts depart this machine and arrive to the next machine?
f. What is the squared coefficient ofvariation of inter-departure times from this machine?
