Abstract: To make fair and reasonable assessment on all kinds of smart phones in the market, fuzzy comprehensive evaluation based on coefficient of variation and the weighted average method is put forward to establish smart phone evaluation model. The model makes classification analysis on the phone’s various performance parameters, utilizes coefficient of variation method to ascertain the weight of each assessindicator, then conducts the single factor evaluation, sets up fuzzy comprehensive evaluation matrix, takes the weighted average model to make comprehensive evaluation, thus the assess result is finally obtained. It is presented by the comparison experiment that compared with the fuzzy comprehensive evaluation based on the expert weighting method and the max-min algorithm, the practicality and effectiveness of the assessment model are greatly promoted and can better reflect the mobile phone’s actual assessment result.

Key words: smartphone assessment model, fuzzy comprehensive evaluation, coefficient of variation method, single factor evaluation, weighted average model
