The Multiple Attribute Decision Making in Analysis of the Design Parameteres of Chair

The weight of the human body transfers by sitting over bones and surrounded soft tissue on the chair and vice versa. Design of the chair suitable for the human body from the ergonomic point of view becomes necessary. Research was done at several workplaces with five different shapes of seats. Testing sample included 37 male and 33 female participants who work while sitting down. Their anthropometrical characteristics were measured: height, weight, sitting pressure, hip and chest circumference, and body posture while working. Seat characteristics were also analysed, including: seat dimensions (width, length), seat shape, seat inclination, seat hardness. The main goal of this research was to determine, out of available chair, which design parameters of chair is more important and must be acceptable into the design process. The paper uses an original model for decision making seating parameters when selecting an acceptable chair. Multiple attribute decision-making model give to the aim for the design of chair.
