Kano-based product configuration design
Based on the method proposed by DuMouchel (Berger et al., 1993), a twodimensional
Kano diagram is established according to customers’ satisfaction
and dissatisfaction levels, as shown in Figure 6. According to this model, the
diagram is divided into four quadrants, and accordingly the FRs are classified
into four categories. Heuristic 1 is adopted to generate product configurations
based on the Kano classification. The product configuration, called Product I,
is generated manually and is shown in Table 8, where a number ‘1’ indicates that the respective FR is included in the product; otherwise, it is left blank. The
Kano evaluator is computed using Eqs. (3)e(7), such that Product I results in
a Kano evaluator of 0.48.
