摘要：The objective of this study is to provide industrial design students with a
comprehensive approach of product evaluation during the course of a research project.
During the design evaluation stage, a student often encounters vague information
since the attributes of product design demands are usually not quantifiable. Therefore,
one of the important topics during the product development processes is to allow a
student to carry out design evaluations effectively. The fuzzy Analytic Hierarchy Process
(AHP) was utilized in this study to assess product designs and resolve the problems
that might occur during product assessments. The purposive sampling technique was
used in the questionnaire survey. By assigning a weighted value to each of the
evaluation criteria, the case study verified the feasibility of the proposed design
approach in fan designs. A total of 52 questionnaire copies were distributed. 36 copies
of them were collected and the return rate is 77%. Among them, 28 copies were from
the engineers and 8 copies were from people in the relevant industries. 22 copies were
from males and this accounts for 61%. On the other hand, 14 copies were from females
and this accounts for 39%. The results indicated that the weight of efficiency which is
the secondary constituent element is the highest. Under the constituent element of
efficiency, the weight of fan flow rate is 0.592 which is the highest. The defuzzification
of efficiency is 0.744 which is the optimal value among the indices of various factors.
The defuzzified value of Design No.4 after defuzzification is 0.682 which is the optimal
one among four design candidates. The results of this study demonstrated the
feasibility of the proposed design approach. New fan styles can be effectively created
by implementing this design approach. This approach allows the entire evaluation
process to be more precise. The combination of these approaches is not only practical
and objective, but also is capable of assisting a student in making a decision under
complicated and uncertain circumstances. This makes a design task definite and better
clarified and also enhances a student’s learning competitiveness by supplying a good
reference during the follow-up stage of product design assessments.
