Facility Location and Plant Layout: Factors, Methods, Types of Layout and Layout Planning (Basics) Questions

Question 1

Define facility location.

Accepted Answer

**Facility location** is the decision of selecting the best geographical place (region/city/site) for a plant, warehouse or service facility.

Question 2

What is plant layout?

Accepted Answer

**Plant layout** is the physical arrangement of machines, departments, workstations, storage areas and material flow within a plant.

Question 3

State one objective of good plant layout.

Accepted Answer

One objective is **minimum material handling**, which reduces time and cost.

Question 4

What is product (line) layout?

Accepted Answer

**Product (line) layout** arranges machines/workstations according to the sequence of operations for a product (assembly line).

Question 5

What is process (functional) layout?

Accepted Answer

**Process (functional) layout** groups similar machines or functions together (e.g., drilling section, painting section).

Question 6

State one factor affecting plant location.

Accepted Answer

One factor affecting plant location is **transportation facilities** (road/rail/port connectivity).

Question 7

Explain factors affecting facility location (any four).

Accepted Answer

Factors affecting facility location (any four):

- **Market proximity**: nearer to customers reduces delivery time and logistics cost.
- **Raw materials**: availability and supplier distance affect transport and reliability.
- **Labour**: availability of skilled labour and wage rates influence productivity and cost.
- **Transportation**: good roads/rail/ports reduce inbound and outbound logistics cost.
- **Utilities**: power and water availability are essential for stable operations.
- **Government policy**: incentives, taxes and regulations influence total cost.

Thus, location selection balances cost, service, and operational feasibility.

Question 8

Explain objectives of plant layout (any four).

Accepted Answer

Objectives of plant layout (any four):

- **Minimum material handling** and reduced movement.
- **Smooth workflow** with fewer delays, backtracking and congestion.
- **Optimum space utilization** (floor and vertical space).
- **Safety and comfort** for workers (less accidents and fatigue).
- **Flexibility** for product change and future expansion.

Hence, a good layout reduces cost and improves productivity and delivery performance.

Question 9

Differentiate between product layout and process layout (any three points) with a table.

Accepted Answer

Product layout vs Process layout:

- **Basis**: sequence of operations vs similarity of functions.
- **Best for**: high volume, low variety vs low volume, high variety.
- **Handling and flow**: smoother flow and less handling vs more movement and complex routing.

Table:

| Basis | Product layout | Process layout |
|---|---|---|
| Volume/variety | high/low | low/high |
| Flow | smooth | complex |
| Flexibility | low | high |

Thus, product layout is efficient for mass production, while process layout is flexible for variety.

Question 10

Explain fixed position layout and its suitability (any three points).

Accepted Answer

**Fixed position layout** keeps the product at one location and brings men, materials and equipment to it.

Suitability/points (any three):
- used for **large and heavy products** that are difficult to move.
- examples: shipbuilding, aircraft assembly, construction projects.
- requires strong **coordination** and scheduling of resources at the site.

Hence, fixed position layout is ideal when product movement is costly or impossible.

Question 11

Explain principles of good plant layout (any four).

Accepted Answer

Principles of good plant layout (any four):

- **Integration**: integrate men, machines, materials and methods for smooth operations.
- **Minimum movement**: reduce distance traveled by materials and workers to save time and cost.
- **Smooth flow**: avoid backtracking, cross movement and congestion.
- **Space utilization**: optimum use of floor space and vertical space.
- **Safety and comfort**: safe paths, proper lighting/ventilation reduce accidents and fatigue.
- **Flexibility**: layout should allow changes and future expansion.

Thus, good layout principles reduce handling cost and improve productivity and safety.

Question 12

Explain factor rating method for location selection (basic steps) with a small table.

Accepted Answer

### **Factor Rating Method (Location Selection)**

Basic steps:
- list important **factors** (market, labour, transport, utilities, policy).
- assign **weights** to each factor based on importance.
- score each location alternative (e.g., 1–10).
- compute **weighted score** = weight × score; total the scores.
- location with highest total score is preferred.

Mini table (format):

| Factor | Weight | Location A score | Weighted | Location B score | Weighted |
|---|---:|---:|---:|---:|---:|
| Market access | 0.30 | 8 | 2.4 | 6 | 1.8 |
| Labour | 0.20 | 7 | 1.4 | 9 | 1.8 |
| Transport | 0.20 | 6 | 1.2 | 8 | 1.6 |
| Utilities | 0.30 | 7 | 2.1 | 7 | 2.1 |

Thus, factor rating converts qualitative factors into a numerical comparison for choosing the best site.

Question 13

Explain location selection procedure (exam-style) and include a simple flowchart.

Accepted Answer

### **Location Selection Procedure (Exam-Style)**

Facility location is a long-term decision and is usually done in stages.

#### **Steps**
- **Step 1: Decide requirements**: type of facility, capacity, market coverage, legal constraints.
- **Step 2: Select broad region**: choose country/state/region based on market and resources.
- **Step 3: Shortlist cities/communities**: compare alternatives on labour, transport, utilities, policy.
- **Step 4: Evaluate sites**: land cost, expansion, connectivity, power/water, risk and environment.
- **Step 5: Compare alternatives**: use **factor rating** (weighted scores) and cost analysis.
- **Step 6: Final selection and implementation**: acquire site and start construction.

Flowchart:

```text
Define needs → Select region → Shortlist cities → Evaluate sites
      ↓
Weighted scoring + cost comparison → Choose best location → Implement
```

**Conclusion:** A systematic procedure reduces risk and ensures lowest total long-run cost with good service level.

Question 14

Explain types of plant layout with suitability, merits and limitations (exam-style with table).

Accepted Answer

### **Types of Plant Layout (Exam-Style)**

Selection of layout depends on volume-variety, product size, and process type.

Table:

| Layout type | Suitable for | Merits | Limitations |
|---|---|---|---|
| **Product (line)** | high volume, low variety | smooth flow, low handling, easy supervision | low flexibility; line stoppage risk |
| **Process (functional)** | low volume, high variety | high flexibility; better machine utilization | high handling; complex scheduling |
| **Fixed position** | very large/heavy products | product not moved | coordination difficult; resource movement cost |
| **Cellular** | part families | flow + flexibility; lower setup | design complexity; needs GT analysis |

**Conclusion:** A good layout improves productivity by reducing movement, waiting and defects while ensuring safe and smooth operations.

Question 15

Explain material handling: meaning, objectives and principles (exam-style with a flow).

Accepted Answer

### **Material Handling (Exam-Style)**

**Meaning:** Material handling includes the **movement, storage, control and protection** of materials throughout production and distribution.

#### **Objectives**
- reduce handling cost and time
- reduce damage and improve safety
- support smooth workflow and reduce delays
- improve space utilization

#### **Principles (key points)**
- **minimum handling** and minimum distance
- **standardization** of containers/equipment
- **mechanization/automation** where economical
- **safety** and prevention of damage
- continuous and smooth flow (avoid backtracking)

Flow (simple):

```text
Receive → Store → Move to point-of-use → Process → Move to next operation → Dispatch
```

**Conclusion:** Good material handling combined with good layout reduces waste, improves productivity, and supports on-time delivery.
