QCM : Supply Chain Fundamentals and Decision Strategies — 18 questions

Questions et réponses du QCM

1. Which supplier had the highest weighted score in the example?

All suppliers had the same score
Supplier 2
Supplier 3
Supplier 1

Supplier 1

Explication

Supplier 1 had the highest weighted score at 8.155, exceeding Supplier 3 and Supplier 2. The winner in AHP is the alternative with the largest weighted score.

2. What is the main purpose of supply chain management?

To keep each function independent to reduce coordination costs
To eliminate all intermediaries between suppliers and customers
To maximize production volume regardless of demand
To coordinate activities across the chain to optimize stakeholder value

To coordinate activities across the chain to optimize stakeholder value

Explication

Supply chain management is the coordination of activities across the chain to optimize stakeholder value. It is not about eliminating all intermediaries or maximizing output without regard to demand.

3. What is the main goal of aggregate planning in this course?

To set consumer prices for each product line
To replace all strategic decisions with daily operating rules
To determine the best warehouse location for the next decade
To balance production capacity with demand forecasts over the intermediate future

To balance production capacity with demand forecasts over the intermediate future

Explication

Aggregate planning is a tactical process that balances capacity with forecast demand over the intermediate future. It focuses on production quantities and timing, not pricing or long-term network design.

4. What is the correct next step after pairwise comparisons in the Analytic Hierarchy Process?

Discard inconsistent comparisons without calculating weights
Convert all criteria into binary pass-fail values
Normalize the matrix and average the row values to obtain criteria weights
Choose the supplier with the highest raw rating on one criterion

Normalize the matrix and average the row values to obtain criteria weights

Explication

In AHP, the pairwise comparison matrix is normalized and row averages are used to derive weights. Those weights are then used in weighted scoring of alternatives.

5. Which plan had the lowest total cost in the comparison?

Plan 1 with $60,350
Plan 2 with $54,465
Plan 1 and Plan 3 tied
Plan 3 with $55,209

Plan 2 with $54,465

Explication

Plan 2 had the lowest total cost at $54,465, lower than Plan 1 and Plan 3. The comparison table identifies it as the cheapest option.

6. What does subcontracting strategy do when internal production cannot satisfy demand?

It lowers demand by offering price discounts
It meets excess demand by outsourcing part of the required output
It shifts unmet demand into future periods as backorders
It keeps the workforce constant and refuses extra orders

It meets excess demand by outsourcing part of the required output

Explication

Subcontracting covers excess demand by obtaining output from an external supplier. Backordering is a different choice because it carries unmet demand forward.

7. Which sequence lists the major supply chain functions in the order presented?

Sourcing and purchasing, transport, inbound storage, production, outbound storage, distribution, sales
Transport, sales, sourcing and purchasing, production, inbound storage, outbound storage, distribution
Sales, distribution, outbound storage, production, inbound storage, transport, sourcing and purchasing
Production, sourcing and purchasing, sales, transport, inbound storage, distribution, outbound storage

Sourcing and purchasing, transport, inbound storage, production, outbound storage, distribution, sales

Explication

The listed sequence matches the main functions described: sourcing and purchasing, transport, storage inbound, production, storage outbound, distribution, and sales. The other orders mix the functions incorrectly.

8. What best describes a supply chain?

A pricing system that links customer demand to retail discounts
A network of parties that move goods and services while coordinating information and money from raw materials to customers
A transport route used only to deliver finished products to stores
A single factory that transforms raw materials into finished goods for local sale

A network of parties that move goods and services while coordinating information and money from raw materials to customers

Explication

A supply chain is defined as a network of parties that coordinate goods/services, information, and money from raw materials to customers. The other options describe only isolated parts of the chain or unrelated concepts.

9. Which statement best describes a chase strategy?

It sets production in each period to match that period’s forecasted demand
It relies only on subcontracting to meet demand spikes
It keeps production rate uniform across the entire planning horizon
It ignores forecasted demand and uses historical averages only

It sets production in each period to match that period’s forecasted demand

Explication

A chase strategy adjusts production each period to follow forecast demand. A level strategy is the one that keeps output uniform.

10. In the level-plan scenario, how many workers are required when 50 units per day are needed, labor time is 1.6 hours per unit, and regular time is 8 hours per day?

8 workers
11 workers
10 workers
9 workers

10 workers

Explication

The calculation is 50 × (1.6 / 8) = 10 workers. This is the required workforce for the regular-time level plan.

11. Which flow refers to the exchange of data that supports planning, forecasting, and coordination across supply chain activities?

Financial flow
Goods and services flow
Information flow
Reverse logistics flow

Information flow

Explication

Information flow is the exchange of data used for planning, forecasting, and coordination. Goods and services flow is physical movement, while financial flow concerns payments and cash flows.

12. How is a supplier’s overall score obtained in the multicriteria approach?

By averaging only the raw cost values across suppliers
By multiplying the number of criteria by the supplier rank
By combining its performance on each criterion using the criteria weights
By using the highest score on one criterion and ignoring the rest

By combining its performance on each criterion using the criteria weights

Explication

The overall supplier score is a weighted combination of performance across criteria, using the derived criteria weights. This allows multiple factors to influence the ranking.

13. What is the backorder cost in the case study?

$45 per unit per month
$20 per unit per month
$40 per unit per month
$2 per unit per month

$20 per unit per month

Explication

Backorder cost is given as $20 per unit per month for unmet demand carried forward. The other figures correspond to different costs in the scenario.

14. How is the average production requirement calculated in the planning example?

Total expected demand divided by the number of working days
Regular hours per day multiplied by labor hours per unit
Total inventory divided by forecast demand
Hiring cost divided by workforce size

Total expected demand divided by the number of working days

Explication

The course uses average production requirement as total expected demand divided by the number of working days. This converts total demand into a daily target.

15. Which set of monthly demands is used in the aggregate planning case study?

500, 450, 600, 400, 550
450, 600, 500, 400, 550
400, 450, 500, 550, 600
450, 500, 600, 550, 400

450, 500, 600, 550, 400

Explication

The case study lists monthly demand units of 450, 500, 600, 550, and 400 for January through May. The other sequences rearrange these values.

16. Which decision is an example of a strategic procurement choice?

Scheduling a shift for tomorrow morning
Issuing a daily transport route
Selecting a supplier and negotiating a contract
Counting end-of-day inventory

Selecting a supplier and negotiating a contract

Explication

Strategic procurement includes sourcing choices, supplier selection, and contracting. The other options are tactical or operational actions rather than strategic procurement decisions.

17. Why is a level strategy often preferred in aggregate planning?

Because it removes the need for any demand forecasting
Because it uses only external suppliers
Because it guarantees zero inventory at all times
Because a stable workforce can improve commitment and product quality

Because a stable workforce can improve commitment and product quality

Explication

The level strategy is based on maintaining a stable workforce, which can support commitment and quality. It does not eliminate forecasting or guarantee zero inventory.

18. What does multicriteria decision making mean in supplier selection?

Selecting the supplier with the highest advertised market share
Ranking options using several criteria rather than a single metric
Picking the alternative that performs best on cost alone
Choosing the supplier with the lowest shipping distance only

Ranking options using several criteria rather than a single metric

Explication

Multicriteria decision making evaluates alternatives using several criteria, such as cost, safety, and flexibility. It is not limited to a single factor like price or distance.
