Operations Management: Sustainability and Supply Chain Management 13th edition by Jay Heizer Test ba

(a)  If a worker can produce 10 parts/hour, how many workers are needed on each shift?
(b) If each shift has 100 workers, what is the productivity of an individual worker?
(c)  If material costs are $10/part, capital costs are $100,000 and labor costs are $10/hour, what is the multifactor productivity of the plant from part (a)?
Answer: 
(a)  100,000 parts × (1 hour / 10 parts) × (1 shift / 8 hours) × (1 worker/60 shifts) = 20.83 = 21 workers
(b) 100,000 parts / [(60 shifts/worker) × (100 workers) × (8 hours/shift)] = 2.08 parts/hour
(c)  100,000 parts / [($10/part) × (100,000 parts) + $100,000 + (21 workers) × (60 shifts/worker) × (8 hours/shift) × ($10/hour)] = .083 parts/$1

46) The local fast-food store experienced the following number of customers on the night shift:
Hour                   Customers
12 AM                     35

2 AM                       15
3 AM                         5
4 AM                         2
5 AM                         1
If the store was staffed by three workers, what was the average productivity per worker, in customers/hour?
Answer:  (35 + 28 + 15 + 5 + 2 + 1) customers/ (3 workers ∗ 6 hours/worker) = 86/18 = 4.78 customers/hour
