Correct answer: A process where trading partners jointly develop demand forecasts and replenishment plans

CPFR is a supply chain collaboration process in which retailers and suppliers share data to jointly develop forecasts and replenishment orders.

Question 3: What is 'Capacity Requirements Planning' (CRP) used for?

To schedule deliveries from suppliers
To set the aggregate production rate
To determine safety stock levels
To calculate detailed capacity loads for work centers based on open and planned orders (Correct answer)

Correct answer: To calculate detailed capacity loads for work centers based on open and planned orders

CRP calculates the capacity load on each work center from both open production orders and MRP planned orders.

Question 4: Actual output divided by standard output is expressed as follows:

Rated capacity
Demonstrated capacity
Efficiency (Correct answer)
Utilization

Correct answer: Efficiency

The ratio of actual output to standard output is defined as efficiency.

Question 5: In MRP, 'lot-for-lot' ordering means:

Ordering a fixed quantity each time
Combining multiple periods' requirements into one order
Ordering based on economic order quantity
Ordering exactly the net requirement for each period with no extra (Correct answer)

Correct answer: Ordering exactly the net requirement for each period with no extra

Lot-for-lot (L4L) is an MRP lot-sizing rule that orders exactly the quantity needed each period, minimizing carrying costs but potentially increasing ordering costs.

Question 6: Which of the following BEST describes a 'push' supply chain strategy?

Suppliers deliver directly to retail shelves based on POS data
Production is based on forecasted demand and inventory is pushed to distribution points (Correct answer)
Safety stock is eliminated by synchronizing production with real-time demand
Products are manufactured in response to actual customer orders

Correct answer: Production is based on forecasted demand and inventory is pushed to distribution points

A push strategy drives production and inventory based on demand forecasts rather than actual customer orders.

Question 7: Total Cost of Ownership (TCO) when evaluating suppliers includes:

Purchase price only
Invoice price plus freight charges
Material cost plus direct labor cost
Purchase price, transportation, quality costs, inventory costs, and supplier development costs (Correct answer)

Correct answer: Purchase price, transportation, quality costs, inventory costs, and supplier development costs

TCO captures all costs associated with a supplier relationship beyond the purchase price, including logistics, quality failures, inventory holding, and the cost of managing the supplier.

Question 8: What is 'intermodal transportation'?

Using air and ocean freight simultaneously for high-priority shipments
Combining two or more modes of transportation (such as rail and truck) to move freight in the same container (Correct answer)
Shipping the same product by different modes to different customers
Using a single mode of transport for an entire shipment from origin to destination

Correct answer: Combining two or more modes of transportation (such as rail and truck) to move freight in the same container

Intermodal transportation moves cargo in a standard container or unit across multiple modes (e.g., ocean then rail then truck) without handling the freight itself at each transfer point.

Question 9: Which supplier evaluation criterion focuses on the percentage of deliveries that arrive on or before the requested date?

On-time delivery performance (Correct answer)
Lead time variability
Quality defect rate
Total cost of ownership

Correct answer: On-time delivery performance

On-time delivery (OTD) rate measures the supplier's reliability in meeting requested delivery dates.

Question 10: Which statistical measure indicates the percentage of time actual demand falls within the forecast range?

Mean absolute deviation (MAD)
Tracking signal
Forecast bias
Forecast confidence interval (or service level) (Correct answer)

Correct answer: Forecast confidence interval (or service level)

A forecast confidence interval specifies the range within which actual demand is expected to fall a given percentage of the time.

Question 11: A product is expected to sell 200 units per month. During the previous six months, the actual demand was 195, 210, 205, 190, 220, and 225. Which of the following values best represents the data's mean absolute deviation?

45
12.5 (Correct answer)
7.5
75

Correct answer: 12.5

To calculate the mean absolute deviation, we need to first find the absolute deviation of each demand value from the forecast, then find the average of those deviations. The absolute deviations from the forecast are: |195-200| = 5 |210-200| = 10 |205-200| = 5 |190-200| = 10 |220-200| = 20 |225-200| = 25 The sum of these absolute deviations is 5 + 10 + 5 + 10 + 20 + 25 = 75. The mean absolute deviation is calculated by dividing this sum by the number of data points, which is 6. Mean absolute deviation = 75/6 = 12.5. Therefore, the answer is 12.5.

Question 12: The 'bullwhip effect' in a supply chain refers to:

Fluctuating transportation costs across carriers
Rapid inventory depletion during peak seasons
Demand variability that amplifies upstream from retailer to manufacturer (Correct answer)
