Decision-making model on DSLR camera choosing for 18 ∼ 30 years old college students

A 3-level Hierarchical Decision Model (HDM) 111 is established in this paper to help 18–30 year old college students make a decision of choosing a desirable digital single-lens reflex camera (DSLR) from 5 famous DSLR camera manufacturers. The HDM has been utilized in this paper, because it measures the relative contribution of each criterion to the final decision based on quantified judgments of the respondents. A group of experts, consists of 12 male and 9 female provided their quantified judgements with different weighted value in each element at each level of the decision hierarchy. By applying desirable functions, there was one most desirable camera picked from each manufacturer of the 5. Additionally. the research team also analyzed the judgments from experts for possible different judgements between gender groups, and showing no significant differences.
