Lesson 9.2: Facility Layout & Plant Location

Facility layout and plant location are critical topics in Industrial Engineering. GATE and PSU exams often test efficient arrangement of resources and optimal site selection.

🔹 1. Introduction

• Definition:

  • Facility Layout: Arrangement of machines, equipment, and workstations for efficient workflow

  • Plant Location: Selection of geographical site for the facility to minimize costs and maximize productivity

• Applications: Manufacturing plants, warehouses, assembly lines, service industries

• Key Concepts: Workflow efficiency, material handling, transportation cost, accessibility

🔹 2. Facility Layout

• Objectives:

  1. Minimize material handling cost

  2. Reduce production time

  3. Improve safety and working conditions

• Types of Layouts:

  1. Process Layout: Machines grouped by function

  2. Product Layout: Machines arranged according to production sequence

  3. Fixed-Position Layout: Product remains stationary, resources move

  4. Cellular Layout: Machines grouped in cells for family of products

• Techniques:

  • Systematic Layout Planning (SLP)

  • Flow diagrams and relationship charts

  • Computer-aided layout design

🔹 3. Plant Location

• Factors Influencing Location:

  • Proximity to raw materials

  • Transportation facilities

  • Power, water, and utilities

  • Labor availability and cost

  • Government policies and incentives

• Evaluation Methods:

  1. Factor Rating Method – Assign weights and scores to location factors

  2. Break-Even Analysis – Compare total cost at different locations

  3. Transport Method – Minimizing transportation costs

• Objectives: Minimize total cost, maximize operational efficiency, ensure long-term sustainability

🔹 4. Solved Examples (PYQ Style)

1. Select suitable layout type for a batch production unit

2. Perform factor rating for three proposed plant locations

3. Use break-even analysis to compare two plant sites

4. Draw flow diagram for product layout and identify bottlenecks

🔹 5. Practice Exercises

1. Identify best layout type for a small-scale industry

2. Calculate weighted score for plant location selection

3. Solve break-even problems for fixed and variable costs

4. Prepare a simple facility layout diagram

5. Compare advantages and disadvantages of different layouts

🔹 6. Summary

• Facility Layout: Arrangement of resources to maximize workflow efficiency

• Plant Location: Optimal site selection for cost reduction and accessibility

• Types of Layouts: Process, Product, Fixed-position, Cellular

• Evaluation Methods: Factor rating, Break-even, Transport

• Exam Tip: Focus on layout selection, cost analysis, and evaluation techniques
