4.4 Evaluation and Application of Results
This study uses data mining cycle in QFD to
forecast future CRs. In addition, the time seriesbased
data mining cycle can be applied to predict
the weights and determine the trend of each CR for
the next period. The use of time series-based data
mining cycle to predict the weights is advantageous
because it can (1) find the future trend of CRs; (2)
provide the computer designers and manufacturers
with reference points to satisfy CRs in advance. The
results of this study can provide an effective
procedure of identifying the trends of CRs and
enhance customer relationship management in the
computer marketplace.
Owing to the entire forecast methods have
forecast errors, the Mean Squared Error (MSE) and
control charts of forecast were applied to monitor
