  1. Experiment design of washing process 于航，姜伟，张博 田益凡，郑奇威

  2. Agenda • Motivation and object of the experiment • Selection of factors • Definition of response variable • Design of experiment • Analysis of experiment • Conclusion • Shortcomings and future extension

  3. Motivation And Object • Study the washing process and try to find the satisfied optimal settings of parameters to make the washing process efficient and effective

  4. Selection Of Factors • Held constant factors • Category and amount of blots (black ink) • Category and amount of washing powders (DiaoPai) • Category of wash (cotton) • Dimension of wash (20×20mm) • Method of washing (marinating) • Design factors • Quantity of water • Time • Initial temperature

  5. Range And Levels Of Design Factors

  6. Definition Of Response Variable

  7. Design Of Experiment • Choice of design • Response surface methodology • central composite design • Number of replicates • Only one replicate is performed

  8. Design Of Experiment(cont’d)

  9. Experiment Implementation

  10. Experiment Analysis

  11. Experiment Analysis

  12. Experiment Analysis(cont’d)

  13. Experiment Analysis(cont’d)

  14. Experiment Analysis(cont’d)

  15. Experiment Analysis(cont’d)

  16. Experiment Analysis(cont’d) R^0.5=(1.86+0.47A-0.20B+0.36C)

  17. Experiment Analysis(cont’d)

  18. Conclusion • In order to maximize the response variable, we need to: • Maximize A • Minimize B • Maximize C • However, the values of A, B and C should be within the feasible region, that is we also have to take other constrains into our consideration: • High temperature can do damage to the clothes • Marinate too long may result in bad smell • Economy reasons

  19. Shortcomings and future extension • Shortcomings • Without considering economical factors • Single blot • Simple evaluation system • Fixed ranges of parameters • Future extension • Extend range of blots • Perfect the evaluation system • Extend the experiment parameter range
