Abstract
Layout designing is one of the most useful research domains for improving the facility efficiency and human resources in organizations, since it composes the best layout designed by engineers to the organization by qualitative and quantitative criteria and choosing the best alternative. In this paper, a corrected non-linear programming method with Grey correlations has been used for choosing the best layout among the layouts produced by ALDEP software, because in choosing a layout design, several criteria with regard to the quality and quantity are simultaneously considered. The decision makers have to choose between Layout design alternatives and their choice have to consider all decision criteria. Wide range of approaches have been introduced to help decision makers this study presents an integrated model of Gray relation analysis and non-linear programming method and create some improvements on previous studies. By using the proposed method in this study, besides considering the variety of criteria, maximizing and minimizing the criteria has also been done simultaneously.
