Zegordi Department of Industrial Engineering,Tarbiat Modares University F. Jariri Department of Industrial Engineering,Tarbiat Modares University Journal Article 2009 05 27 In this paper, the need to incorporate three famous design cost management methods, called: Quality Function Deployment (QFD), Value Engineering (VE) and Target Costing (TC) into a single model has been addressed. Each method performs very well in cost management procedures as design activities. These methods have been incorporated into a mathematical programming model, in order to achieve the maximum benet of each method. The model, essentially, optimizes customer satisfaction subject to target cost. The tool is a mixed integer zero-one nonlinear programming. The unied model has been proposed to prevent a non-optimal solution when methods interact with each other. The practitioner should be condent that the quality solution would be achieved in contrast to when the methods are applied sequentially. A simple automobile design example was formulated and solved to show the performance of the model. https://scientiairanica.sharif.edu/article_2947_da3affdb30438a91b2a922e8f87ea4d7.pdf
