The image outlines a problem where Dell purchases components from three suppliers (A, B, and C). Currently, Dell uses a separate truck for each supplier, but the goal is to minimize the total cost by aggregating purchases.

Here is a summary of the data presented:

- **Fixed trucking cost**: $100 per truck.
- **Additional cost**: $100 per stop.
- **Supplier details**:
    - **Supplier A**: 
        - Price: $5/unit
        - Rate of use: 20,000 units/month
    - **Supplier B**: 
        - Price: $4/unit
        - Rate of use: 2,500 units/month
    - **Supplier C**: 
        - Price: $2/unit
        - Rate of use: 900 units/month

### Current Strategy:
Dell uses separate trucks for each supplier. Thus, the trucking costs for the current system are:
- For each supplier, one truck: $100 (fixed) per supplier.
- No additional stop charges since trucks are dedicated to each supplier.

### Suggested Aggregation Strategy:
To minimize costs, Dell could aggregate the shipments from all three suppliers into a single truck and make stops at each supplier. The cost structure would be as follows:
1. **Truck cost**: $100 fixed per truck.
2. **Additional stops**: $100 for each stop. With three suppliers, the truck would make two additional stops.

Thus, the total cost for the new aggregated system:
- Fixed cost: $100 (truck) + 2 × $100 (for two additional stops) = $300 per delivery.

### Total Monthly Cost Comparison:
#### Current Strategy:
- For each supplier:
  - Supplier A: 1 truck per month = $100
  - Supplier B: 1 truck per month = $100
  - Supplier C: 1 truck per month = $100
- Total monthly trucking cost: $100 × 3 = **$300**

#### Aggregated Strategy:
- One truck with two additional stops: $300 per month.

Since the trucking costs are the same under both strategies, Dell could benefit from simplifying logistics and improving efficiency through the aggregation strategy without increasing the cost.

Here are some related questions:
1. What would be the total annual cost savings from switching to the aggregated strategy?
2. How would different rates of demand (units/month) affect the total cost in both strategies?
3. What are the potential benefits (outside cost) of using a single truck for all suppliers?
4. How does the per-unit cost influence the decision for aggregation?
5. What other cost factors should Dell consider when switching to an aggregated shipping strategy?

**Tip:** Aggregating deliveries can simplify logistics but may require careful coordination with suppliers to ensure stock levels meet demand.

Dell purchases components from three suppliers. Currently, Dell uses a separate truckload for each supplier. To minimize annual costs, Dell wants to aggregate these purchases. The trucking company charges: A fixed cost of $100 per truck, and an additional $100 for each stop. Supplier details: A: $5/unit, 20,000 units/month. B: $4/unit, 2,500 units/month. C: $2/unit, 900 units/month. Suggest a replenishment strategy to minimize annual cost. Compare it with the current one.
