The main objective of the proposed decision support system is to select the best alternative among a number of digital camera options in respect to different user profiles.
Although there are numerous features of a digital camera, we have studied them mainly in four groups: design and control related criteria, technical criteria, real-life performance related criteria, and the economic criterion (Table 2).
The first three major group of criteria have their own sub-criteria.
In exploring the most reasonable criteria list, the guidance of experts has been of significant value in choosing convenient features.
Even though there are some exceptions, we have given the common requirements for each sub-criterion as its goal. The sign ‘||’ means that the given sub-criterion is required to be maximized, whereas the sign ‘|’ means that the given sub-criterion is required to be minimized.
In this section, we will introduce these features by giving brief descriptions.
