Integrated Approach of Ergonomics and MCDM into Truck Drivers' Seat Comfort: A Case Study in Bangladesh

Abstract

Seats are one of the most significant components for automotive vehicles. Prolonged driving a truck in Bangladesh is not so comfortable because no one design the seat properly considering anthropometric data. The improper seat design causes various health problems. Therefore, the improvement of seating posture is the urgency for reducing health issues. In this paper, a total of 120 Bangladeshi truck drivers were taken as sample for measuring anthropometric data. A comparison of health status between drivers and normal people showed that drivers suffer much than the control group. The relevant feedbacks required for the analysis were collected from the expert's opinion. The integrated approach (AHP-TOPSIS)found that among four health issues, back pain is more critical health issue associated with the existing seat dimension. Finally, the study suggested seat width as the most decisive design parameter on which designers should give much attention while designing truck drivers' seat
