(20 points) A single-station assembly machine performs six work elements to assemble five components to a base part. The elements are listed in the table below, together with the fraction defect rate (q) and probability of a station jam (m) for each of the components added (NA means not applicable). Time to load the base part is 3 sec and time to unload the completed assembly is 4 sec, giving a total load/unload time of Th=7 sec. When a jam occurs, it takes an average of 1.5 min to clear the jam and restart the machine.
