Enter Layout Inputs
Example Data Table
| Scenario | Layout Type | Flow Units/Day | Avg Distance (m) | Area Required (m²) | Adjacency Score | Target Throughput |
|---|---|---|---|---|---|---|
| Baseline Line A | Process | 1200 | 32 | 1200 | 78 | 1400 |
| Improved Cell | Cellular | 1300 | 24 | 1150 | 86 | 1450 |
| Expansion Hybrid | Hybrid | 1500 | 28 | 1400 | 82 | 1600 |
Formula Used
1. Effective Distance
Effective Distance = Average Distance × (1 + Aisle Factor) × Layout Multiplier
2. Monthly Handling Cost
Monthly Handling Cost = Daily Flow Units × Work Days × Effective Distance × Cost per Meter
3. Space Utilization
Space Utilization (%) = (Required Area ÷ Available Area) × 100
4. Throughput Capacity per Shift
Throughput Capacity = (Shift Minutes ÷ Travel Time per Move) × Departments × Utilization × (1 + Adjacency Score ÷ 200)
5. Optimization Score
Optimization Score = (Cost Score × Cost Weight) + (Space Score × Space Weight) + (Flow Score × Flow Weight) + (Safety Score × Safety Weight)
Each score is normalized to 0-100, then weighted by your chosen priorities. This gives a single comparison value for alternative layout scenarios.

FAQs
1. What does this calculator optimize?
It evaluates layout efficiency using distance, handling cost, space use, safety allowances, adjacency, and throughput potential. The goal is a balanced facility arrangement.
2. Why is adjacency score important?
Adjacency reflects how closely related departments sit near each other. Better adjacency usually reduces travel time, waiting, congestion, and coordination losses.
3. What is a good space utilization percentage?
Many operations prefer strong use of space without overcrowding. A result near the practical operating range is usually better than extreme underuse or overuse.
4. Can I compare multiple scenarios?
Yes. Run one scenario, export it, then update the inputs for another option. This helps compare process, product, cellular, and hybrid layouts.
5. Does a lower handling cost always mean a better layout?
Not always. A low-cost layout might still have poor safety access, weak throughput, or excessive crowding. This tool combines several indicators for balance.
6. What should I do if throughput is below target?
Shorten routes, improve department adjacency, rebalance workstations, reduce bottlenecks, or consider additional handling capacity where delays occur.
7. Are the results exact engineering outputs?
No. They are planning estimates based on the inputs you provide. Final layouts should still be validated with measurements, simulations, and shop-floor reviews.
8. When should I use custom weights?
Use custom weights when your factory priorities differ. For example, safety-critical plants may emphasize clearance, while high-volume lines may prioritize flow.
