Part I Productivity Problem George makes bowling balls in his Miami plant. With recent increases in his costs, he has a newfound interest in efciency. George is interested in determining the productivity of his organization. He would like to know if his organization is maintaining the manufacturing average of 3% increase in productivity per year. Units produced 1000 1000 Labor (hours) 300 275 Resin (pounds) 50 45 Capital invested ($) 10000 11000 Energy (BTU) 3000 2850 1. Show this year's the productivity for labor hours. (10pts) 2. Determine the productivity percentage change (improvement) for labor-hours. (5 pts) 3. If George's costs are as follows: 6 Labor: $10 per hour Resin: $5 per pound Capital expense: 1% per month of investment Energy: $.50 per BTU Show the percent change in productivity for one month last year versus one month this year, on a multifactor basis with dollars as the common denominator.

The drilling operation occurs separately from and simultaneously with the sawing and sanding operations. The product only needs to go through one of the three assembly operations (the assembly operations are "parallel") Assembly Sawing Sanding 78min/unit 15min/unit 15min/unit Welding Assembly 25min/unit 78min/unit Driling 20min/unit Assembly 78min/unit a) Which operation is the bottleneck? (10 pts) b) What is the throughput time for overall system? (10 pts) c) If the firm operates 8 hours per day, 20 days per month, what is the daily capacity of the manufacturing process? (10 pts) d) What is the efficiency of Welding? (10 pts)
