A manufacturing line produces biomedical devices such as pacemakers, blood sugar testers, etc. The line consists of 3 single-machine stations with natural process times of 15, 12 and 14 minutes respectively. The second station, “fitting”, is where the assembly of the electronics into the device’s case is performed. This operation relies on a press tool that is somewhat unreliable: the tool is operational only 70% of the time. a) Find the bottleneck, the effective capacity, and all three descriptors for the line (15 points) b) If the availability goes down to 40%, what happens to the critical WIP (Wo)?
