Question: An eight-station automatic assembly machine has an ideal cycle time of 10 sec. Downtime is caused by defective parts jamming at the individual assembly stations The average down-time per occurrence is 3.0 min. The fraction defect rate is 1.0%, and the probability that a defective part will jam at a given station is 0.6 for alt stations. The cost to operate the assembly machine is $90.00/hr, and the cost of components being assembled is $.60/unit assembly. Ignore other costs. Determine:
(a) yield of good assemblies,
(b) average production rate of good assemblies,
(c) proportion of assemblies with at least one defective component, and
(d) unit cost of the assembled product.
