The ABC Company is planning a new product line and a new plant to produce the parts for the line. The product line will include 10 different models. Annual production of each model is expected to be 1000 units. Each product will be assembled of 200 components. All processing of parts will be accomplished in the new plant. On average, 5 processing operations are required to produce each component, and each operation takes an average of 1.5 min (including an allowance for setup time and part handling). All processing operations are performed at workstations, each of which includes a production machine and a human worker. The plant operates one shift. Determine the number of (a) components, (b) processing operations, and (c) workers that will be needed to accomplish the processing operations if each worker works 2500 hr/yr.

Solution

solution

number of components = 10 X 1000 X 200

= 2000000

number of processing operations = 2000000 X 5

= 10000000

Totl operation time = 1.5 X 10000000

= 15000000 min.

number of workers = (15000000) / (2500 X 3600)

   = 1.66

So, 2 workers are required.
