Draw a process flow diagram. Determine the process capacity per week of the entire process. Suppose a second shift of eight hours is run for assembly line 1, and the same is done for the final assembly line. In addition, five of the six drilling machines are put into operation. The drilling machines, however, operate for only eight hours a day. What is the new process capacity per week?
A Company produces a component for use in the aerospace industry. The component consists of three parts (A, B and C), which are purchased externally and cost 50c, 60c and 70c per piece respectively. Parts A and B are assembled first on assembly line 1, which produces 150 components per hour. Part C undergoes a drilling operation before being finally assembled with the output from assembly line 1. There are six drilling machines in total, but only three are currently operational. Each drilling machine drills part C at a rate of 30 parts per hour. The final assembly line has a production capacity of 100 components per hour. At present, components are produced eight hours a day, five days a week.
If the need arises, management can add a second shift of eight hours for the assembly lines only.
The cost of assembly labour is 40c per assembly operation for each assembly line; the cost of drilling labour is 20c per part. For drilling, the cost of electricity is 10c per part. The overhead cost is $10 000 per week.
