A Compromise Solution by VIKOR Method for Ergonomically Designed Product with Optimal Set of Design Characteristics

Customer satisfaction is considered as the most important factor in designing a product ergonomically. Products should satisfy customer's choice of preference in terms of their comfort level. So choosing a product with optimum design characteristics in order to achieve customer satisfaction is essential. Since it is difficult to find out an optimum set of design parameters for a product in order to meet all customers’ need, a feasible way considering Multi Criteria Decision Making (MADM) approach is used to select a product carrying all the specified function. This paper proposes a framework of MADM based on Višekriterijumsko kompromisno rangiranje (VIKOR) method to select ergonomically designed office chair in order to improve the comfort level. Keeping customer preference in mind ten design characteristics (attributes) and six alternatives are considered to develop the framework. The proposed method considers decision maker's (DM'S) preference to judge this parameter in order to fit the product to a range of user.
