description |
Decision-making has always been a vital part in product development. Especially with
the rapid technological advancement today, the competitive market demands designers
to make tough choices while the product development cycle is becoming shorter and
shorter. In order to capture the market, they have to be able to capture the customers’
wants and needs. Hence, this leads to the development of decision-support systems to
aid designers.
There are decision-support systems built based decision analysis and multiple-attribute
decision making methods. Partial Least Squares regression (PLSR), a recently developed
modeling technique, and Customer-revealed Value (CRV) are employed in this study in
an effort to develop a more comprehensive decision making method. PLSR is able to
construct predictive models using multiple collinear factors while CRV is able to capture
customer preference by relating the demand of the product.
In this research, the ability of PLSR to be a decision support system is investigated by
testing this technique in the mobile phone industry. Predictive PLS models are
constructed based on mobile phone attributes as input (X-matrix) and expert and
consumer ratings for CRV as responses (Y-matrix). Using VIP, 10 influential attributes
are first selected. Then, the PLS models are trimmed down to these 10 attributes before
going through validation. The plots of each model are used to validate the PLS models.
Then, the prediction ability of the models is examined to further check the validity and
reliability of the models.
The author proved the effectiveness of using PLSR to model customer preference for the
mobile phone industry as the predictive models are valid and able to predict the
responses of the validation sets accurately. |
