    • standerdization
      • 11.advantage of standardization
        • for disabilities
          • for wheelchairs
          • for blinds
            • example in Tokyo Subway
    • examples
      • Metro in Lisbon
      • Tokyo subway
• 12. other levels of systems
  • new problems
    • markets
    • regional economic unification
    • cultures
    • globalization
      • 13.continue in the issue of globalization
  • products
    • development
    • manufacture
• 14. mass production
  • early stage
    • unflexible
    • better when standardizing the product
  • now
  • example
    • produce cars for right- or left- handed
• 15. design for mass production
  • for discrete products
    • particular purpose
      • specific assemblies
        • differentiation in the market
  • new technologies
    • flexible production
    • emphasis on process
    • standardize interfaces or connections
• 16. example in National Bicycle Industrial Company of Japan for #15
  • customers specify models
    • customers' dimention
    • additional components
    • color preference
  • different blueprint
    • combination of standardized and cut-to-fit parts
• 17. another example: Motorola
  • 29 million variants of pager
    • elimination of being tied up in inventories
    • enhance customer satisfaction
• 18. another example: Hewlett-Packard (how they achieve it)
  • printers
    • delay product differenciation
    • adaptable
    • able to integrate
    • delivered to the nearest point to customers
    • configure to meet the particular context, exp. electrical sys.
• 19. a short summary of manufacture and customize in these days which lead to modules and platforms
• 19. Modular units (follow the configuration idea)
  • overall structure
    • add-on optional elements
    • interface elements
    • essential functional components
    • able to customize
    • group in standard modular units
    • example
      • Lego
• 20. evolution of Modular systems
  • 1910s, unit furniture
  • 1920s, able to group and adapt by different users
  • 1980s, kitchen systems
    • computer simulation
    • examples
      • Siematic
      • Poggenpohl
    • less expensive stocks and warehousing
• 21. more about Modular systems
  • electronic manufactures
    • prolific variations of audio and visual products
    • example
      • Dell Computers
        • specification by customers through internet
• 22. short conclusion of the modules
• 22. product platforms
  • serve basic functional purpose
  • rapidly manufacture a variety of product configurations
    • able to response to the changing and competitive market rapidly
  • example
    • Sony's Walkman in 1979
    • 23. other examples follow #22 platforms
      • 1987 Fuji camra
        • Kodak in response to Fuji
          • 1994, Kodak had 70% of US market
• 24. another example of platforms: Ford Motor Corporation
  • in order to restructure the company as a global organization
    • restrict by global dimentions
    • idea of platform
      • enable Ford to manufacture wherever cheaper
      • also adapt for different markets
      • rapidly response to the new needs
• 25. short conclusion of the platforms in manufacture systems
  • resolve the contradiction
    • manufacture in high volumes economically
    • fulfill the needs of individual customers
    • distinctiveness and commonality work side by side
  • 26. advantages
    • better follow-up services
    • example
      • personal copier by Canon
        • ink refill + element service in a common module
• 27. artificial system vs. biological world (the parts and the whole)
  • compatibility
  • how changes in one part consequences the whole
    • effects on other overlapping systems
  • solution
    • design
  • possible problem
    • design
      • self-interest
      • subsystem within economic and social systems
