  1. 1. Facility Layout Chapter 10pages 345-349, 359-360, 367-368
  2. 2. MGMT 326Foundations Products & Quality Planning Facilitiesof Operations Processes Assuranc & Control e Managing Managing Capacit Introduction y Projects Quality and Strategy Product Statistical Location Design Process Facility Control Layout Process Design Just-in-Time & Lean Systems
  3. 3. Presentation Outline Importance of layout planning Process and product layouts Office layouts Designing cellular layouts
  4. 4. What Is Layout Planning? Layout planning is determining the best physical arrangement of resources within a facility
  5. 5. Why is layout planning important? Eliminates unnecessary costs for space and materials handling Reduces work-in-process inventory Produces goods and services faster Reduces distances that workers must travel in the workplace Improves communication and morale Increases retail sales Improves brand image
  6. 6. Types of Layouts Process layouts: Group similar resources together Product layouts: Designed to produce a specific product, or a small number of products efficiently Hybrid layouts: Combine aspects of both process and product layouts  Example: cellular layout Fixed-Position layouts: Product is too large to move  Examples: building construction, shipyard  Resources must be brought to where they are needed
  7. 7. Process and Product Layouts
  8. 8. Process Layouts Used in project and batch manufacturing (intermittent processes) Also used in department stores, offices, hospitals, and universities Able to make or sell a variety of products Use general purpose resources Less automation than in product layouts
  9. 9. Process Layouts (2) Material handling costs per unit are higher than in product layouts Scheduling production is more complex than in product layouts
  10. 10. Product Layouts Used in assembly lines and continuous manufacturing (repetitive processes) A cafeteria line is a product layout In manufacturing, product layouts are used to produce one product, or a small group of products, efficiently Uses special purpose resources More automation than in process layouts
  11. 11. Product Layouts (2) Material handling costs per unit are lower than in process layouts Scheduling production is simpler than in process layouts
  12. 12. Designing Process Layouts Step 1: Gather information:  Space needed, space available, importance of proximity between various units Step 2: Develop alternative block plans:  Using trial-and-error or decision support tools  2 approaches  Relationship (REL) chart  From-to matrix  Can use both  Decision support systems are heuristic methods  Usually give a "good" solution  Solution may not be optimal (best solution)
  13. 13. Designing Process Layouts (2) Step 3: Develop a detailed layout  Consider exact sizes and shapes of departments and work centers including aisles and stairways  Tools like drawings, 3-D models, and computer-assisted design (CAD) software are often used

  18. 18. Process Layout Example (5)
  19. 19. Designing Product Layouts Objectives  Produce the required number of units to meet demand  Use workers and equipment efficiently  High utilization of workers and equipment  Balance workload among employees
  20. 20. Designing Product Layouts (2) Based on a precedence diagram Assign tasks to work stations Assign work stations to locations
  21. 21. Office Layouts Almost half the U. S. work force works in an office Human interaction and communication are the primary considerations in office layouts People who need to interact frequently should be close to each other One key layout tradeoff is between closeness and privacy
  22. 22. Office Layouts (2) Open concept offices promote understanding and trust. A few closed rooms are needed for private discussions, such as personnel matters. Moveable walls provide flexibility to change the layout when needed.
  23. 23. Office Layout Example 3D Systems Hi-tech company – provides equipment and materials for rapid product design and manufacturing Rock Hill headquarters handles product design, sales, training, and administration Open office plan Conference room Areas for informal meetings Product showroom for customers Cyber café and fitness center for employees
