Question 1
Which of the following decision support tools is used to determine capacity requirements on the basis of future demand?
Correct Answer: B
Rationale: Forecasting is the process of predicting future demand, which is directly used to calculate the capacity needed to meet that demand. Capacity cushions are buffers of extra capacity, not a tool for determination. Break-even analysis calculates the point where revenue equals costs, not future capacity needs. Decision trees are used for evaluating decisions under uncertainty, not specifically for capacity planning based on demand.

Question 2
In the case of this hospital facility, which of these is an output measure of capacity?
Correct Answer: C
Rationale: Output measures of capacity reflect the actual volume of work completed or services delivered. The number of patients treated per month is a direct measure of the hospital's output. Available beds, floor space, and operational hours are all input measures; they represent the resources or potential capacity available, not the actual utilization or output achieved.

Question 3
Where should the new store be located?
Correct Answer: A
Rationale: The factor rating method involves multiplying the weight of each factor by the score for each location and summing the results to get a total score for each location. Location 1: (0.10*100)+(0.05*80)+(0.40*70)+(0.10*86)+(0.20*40)+(0.15*80) = 10 + 4 + 28 + 8.6 + 8 + 12 = 70.6. Location 2: (0.10*60)+(0.05*80)+(0.40*90)+(0.10*92)+(0.20*70)+(0.15*90) = 6 + 4 + 36 + 9.2 + 14 + 13.5 = 82.7. Location 3: (0.10*70)+(0.05*80)+(0.40*35)+(0.10*90)+(0.20*50)+(0.15*80) = 7 + 4 + 14 + 9 + 10 + 12 = 56. Location 4: (0.10*90)+(0.05*80)+(0.40*40)+(0.10*88)+(0.20*70)+(0.15*90) = 9 + 4 + 16 + 8.8 + 14 + 13.5 = 65.3. Location 2 has the highest total score of 82.7.

Question 4
What is the role of a process flowchart?
Correct Answer: A
Rationale: A process flowchart is a visual representation that uses symbols and arrows to show the sequence of steps, decision points, and flow of materials or information in a process. Its primary role is to depict this sequence clearly. While it can indirectly aid in evaluation or identifying bottlenecks, its core function is illustration, not direct production, determining the longest task, or evaluation, which are analytical uses of the created flowchart.

Question 5
What does process velocity measure?
Correct Answer: C
Rationale: Process velocity, also known as throughput ratio, is defined as the ratio of total throughput time (the total time a unit spends in the system) to value-added time (the time during which work is actually being performed on the unit). A lower ratio indicates greater efficiency. The average movement time describes throughput time itself. Performance against standards relates to quality or efficiency metrics. Resource utilization measures the percentage of time a resource is busy.
