Section B - Case 1: AeroBlade Dynamics

AeroBlade Dynamics manufactures heavy wind turbine blades. They produce two models: Standard and Advanced. The factory operates a highly specialized molding machine which is the bottleneck resource. Total bottleneck hours available per month are 3,000 hours. Total factory costs (excluding direct materials) are $120,000 per month.

Data per unit:
Standard Blade: Selling Price = $200, Direct Material Cost = $80, Machine Hours = 2 hours.
Advanced Blade: Selling Price = $350, Direct Material Cost = $150, Machine Hours = 4 hours.

Calculate the Return per Factory Hour for the Advanced Blade. (Enter the number only)

Section B - Case 1: AeroBlade Dynamics

AeroBlade Dynamics manufactures heavy wind turbine blades. They produce two models: Standard and Advanced. The factory operates a highly specialized molding machine which is the bottleneck resource. Total bottleneck hours available per month are 3,000 hours. Total factory costs (excluding direct materials) are $120,000 per month.

Data per unit:
Standard Blade: Selling Price = $200, Direct Material Cost = $80, Machine Hours = 2 hours.
Advanced Blade: Selling Price = $350, Direct Material Cost = $150, Machine Hours = 4 hours.

What is the Throughput Accounting Ratio (TPAR) for the Standard Blade?

Answer options:

A.

1.25

B.

1.50

C.

0.67

D.

3.00

How to approach this question

1. Calculate Return per hour for Standard: (200 - 80) / 2. 2. Calculate Cost per hour: 120,000 / 3,000. 3. Divide Return per hour by Cost per hour.

Full Answer

B.1.50✓ Correct
Throughput Return for Standard = $200 - $80 = $120. Return per hour = $120 / 2 hours = $60/hr. Cost per hour = $120,000 / 3,000 hours = $40/hr. TPAR = $60 / $40 = 1.50.

Common mistakes

Calculating TPAR for the wrong product or inverting the formula.
