Choose orthogonal table
  • Proposed standard methodchoose the first level
    of factor A as a virtual level,
  • So we can choose L16(45)which has equal level and
    just conduct 16 tests.

  • The best combination of apple juice is A3B4C4An
    apple and a half, five teaspoons of sugar, four
    tablespoons of vinegar.

25
  • The order of the significant factors is ABC,
    which means the greatest impact on the taste of
    the apple juice is the number of apples,
    followed by sugar,and vinegar is the least

  • By analyzing the significance of each factor
    level, considering the low-cost, easy to operate
    and other factors, we get the best combination of
    apple juice A3B4C1-- by means of analysis of
    variance.

  • Error e1.3
  • The personal preferences, for instance some
    people prefer sweet, but some people prefer sour

30
  • Other factors that may affect the taste of the
    apple juice that we do not know
  • Because of the existence of errors in personnel,
    raw materials, environment, these can lead to
    large errors in the final results

Summary
  • As an undergraduate, through this test, our
    greatest achievement is not the results of the
    experiment itself, but rather learn how to apply
    the knowledge learned into practice.For
    companies,adoping this method can both save cost
    and meet the consumer demand.
