  1. Week 8A– Layout Strategy(Chapter 9) Layout types: Fixed position, Functional (or Process), Product, Cellular, Mixed SJSU Bus. 140 - David Bentley

  2. Layout Types • Fixed-Position • Functional or Process • Product • Cellular • Mixed SJSU Bus. 140 - David Bentley

  3. Fixed-Position • Product is in a fixed position (e.g., airframe, ship, building, highway, etc.) • Resources (people, machines, material) come to the product • Requires complex scheduling of resources • High space requirements to accommodate resource movement • Usually associated with the Project environment SJSU Bus. 140 - David Bentley

  4. Other Examples - Fixed Position Layout • You’re traveling and find that your muscles are knotted so you call a masseur who comes to your hotel room and gives you a massage. • You are a patient having surgery. SJSU Bus. 140 - David Bentley

  5. Process or Functional • Groups similar resources together by the function or process performed • Machine examples are: milling machines, lathes, routers, grinders • People examples are: Invoicing, Accounts Payable, Payroll Processing • Many crossed paths, high space requirements • Easy to supervise, train, etc. • Usually associated with the Job and sometimes the Batch environments SJSU Bus. 140 - David Bentley

  6. Other Examples - Functional Layout • 24-Hour Fitness Center • Equipment is all arranged in groups • Each person has a different routine and path • Bottlenecks may occur with some equipment SJSU Bus. 140 - David Bentley

  7. Product • Resources are arranged to follow the flow of the product • Examples are: auto assembly, steel production, bottling, etc. • Often called production lines or assembly lines • May be straight line, U-shaped, snake • Provides for very little WIP storage • Usually associated with Repetitive and Continuous Flow environments SJSU Bus. 140 - David Bentley

  8. Other Examples - Product Layout • Curves • Equipment is arranged in sequence • Each person follows the same routine and path • No bottlenecks because each person uses a piece of equipment for specific amount of time which does not vary from station to station SJSU Bus. 140 - David Bentley

  9. Cellular • Resources (labor and equipment) arranged in small groups (cells) • Have responsibility for output, quality, maintenance, etc. for a grouping of tasks or parts • Referred to as “teams” in services sector • Teamwork essential • May be straight line or U-shaped; no WIP storage • Most recently developed layout • Usually associated with Repetitive environment SJSU Bus. 140 - David Bentley

  10. Other Examples - Cellular Layout • Kitchen in a very expensive restaurant • Some staff responsible for hors d’oeuvres, others for salads, others for desserts, etc. • Equipment grouped to meet the needs of each “team” SJSU Bus. 140 - David Bentley

  11. Mixed • Two or more layout types in 1 facility • Examples • Manufacturing: burn-in or baking • Restaurants (kitchen is functional, buffet line is product, menu ordering is fixed-position) • More difficult to plan • More costly to equip • More troublesome to maintain SJSU Bus. 140 - David Bentley

  12. U-Shaped Advantages • Staff flexibility and balance • Teamwork • Immediate rework • Accessibility • Work and tool distribution • Linking with other U-shaped layouts SJSU Bus. 140 - David Bentley
