Fuzzy Comprehensive Evaluation on Body Parts’ Weight Coefficients towards Sitting Comfort Based on AHP to Limit Entropy Method

الملخص EN

In order to quantify the effects of different body parts on sitting comfort, an ontology model for sitting comfort in “human—machine” system was established.

In light of the subjectivity and arbitrariness issue of AHP, as well as the characteristic of entropy method be vulnerable to disturbed by extremum, a new weighting method was implemented which corrects subjective data with objective data, named AHP to limit entropy method.

An overall comfort formula was created containing shoulder, back, waist, buttock, and thigh.

Finally, three other vehicle’s seats were tested as comparative verification, with a result showing that the weighted method was effective.

And this method can provide an effective approach for evaluating sitting comfort.
