2. Assume you are managing a manufacturing line consisting of two workstations: Decambering and Hemming. The mean effective process time of the first machine is 15 minutes and its coefficient of variation is 1 (i.e., exponential distribution). The second machine has the same coefficient of variation, but this machine takes 14 minutes to process a part. (a) If there is an infinite buffer between the machines, compute the expected WIP, CT, and TH.

WIP: _________ TH: _________ CT: _________

(b) Now assume that there is enough space for only 3 parts between the machines (Hint: the buffer size, b, is 3.) Recompute the expected WIP, CT, and TH. Compare with Part a. WIP: _________ TH: _________ CT: _________
