    Competitive Advantages?
    • Customized good or services
    • Machine Shop, Beauty Shop
    • Specialty tools, Hair Styling
    • Quality (performance) & Flexibilty
  9. Describe Batch?
    Examples of Process?
    Examples of Goods & Services?
    Competitive Advantages?
    • Semi-standard goods or services
    • Bakery, Classroom
    • Cookies, education
    • Moderate cost & flexibility
  10. Describe Repetitive/Assembly?
    Examples of Process?
    Examples of Goods & Services?
    Competitive Advantages?
    • Standardized goods or services
    • Assembly line, cafeteria line
    • Automotive line, car wash
    • Low unit cost, Dependability
  11. Describe Continuous?
    Examples of Process?
    Examples of Goods & Services?
    Competitive Advantages?
    • Highly standardized goods or services
    • Steel Mill, Sugar refinery
    • Steel, Paper, Power
    • Low Price, Quality (conformance)
  12. Describe Layout?
    Layout is the configuration of departments, work centers, and equipment, with particular emphasis on movement of work (customers or materials) through the system.
  13. Three basic layout types?
    • 1. Product Layouts
    • 2. Process Layouts
    • 3. Fixed-Position
  14. Describe Product Layout and which processes use it?
    • Product Layout uses standardized processing operation to achieve smooth, rapid, high volume flow.
    • Line
  15. Describe Process Layout and which processes use it?
    • Process layout can handle varied processing requirements.
    • Job Shop or Batch (ex: hospital)
  16. Describe Fixed-Position Layout and process that uses it?
    • Fixed Position is a layout in which the product or project remains stationary, and workers, materials, and equipment are moved as needed.
    • Project! Ex: Building or freeway
  17. Importance of Layout Decisions?
    • 1. Requires substantial investments of money and effort
    • 2. Involves long-term commitments
    • 3. Has significant impact on cost and efficiency of short-term operations
  18. Eight things that cause a need for layout decisions?
    • 1. Inefficient operations
    • 2. Changes in the design of products or services
    • 3. The introduction of new products or services
    • 4. Accidents/Safety hazards
    • 5. Changes in environmental or other legal requirements
    • 6. Changes in volume of output or mix of products
    • 7. Changes in methods and equipment
    • 8. Morale problems
  19. Layout Formats?
    • 1. Group Technology Layout
    • 2. Just-In-Time Layouts
    • -May be assembly-line or
    • -Group Technology formats
    • 3. Fixed Position Layout
    • -eg Shipbuilding
  20. Cellular Layouts include?
    • 1. Cellular Manufacturing
    • 2. Group Technology
    • 3. Flexible Manufacturing Systems
  21. The advantage of Cellular Layouts?
    • They retain flexibility in the process and gain economies of scale.
    • Ex: Lazyboy Case
  22. Explain Cellular Manufacturing?
    Layout in which machines are grouped into a cell that can process items that have similar processing requirements.
  23. Explain Group Technology Layout?
    The grouping into part families of items with similar design or manufacturing characteristics.
  24. A Flow Line for Production or Service?
  25. A U-Shaped Production Line looks like?
  26. Adavantages of U-Shaped Production Line?
    • 1. Shorter distance
    • 2. Workers can alternate tasks
    • 3. Shipping & Receiving can be in 1 place
  27. Describe Process Layout?
    • Departmentalized process where work travels to dedicated process centers
  28. Functional Layout?
  29. Cellular Manufacturing Layout?
    • Part families are based on Group Technology
    • -minimizes material movement
