Fuzzy AHP and fuzzy TOPSIS integrated multicriteria decision-making scheme employing Chinese environmental esthetics for facility layout design evaluation

Facility layout presents a complex design challenge. It is particularly regarded as a vital issue in Chinese society and throughout Asian countries where Feng Shui, the ancient and revered Chinese practice governing environmental esthetics, has played and continues to play a vital role in man-made design. In this research, the innovative merger of a fuzzy analytic hierarchy process and a fuzzy technique for order preference by similarity to ideal solution integrating a fuzzy multicriteria decision-making methodology is proposed for solving facility layout design evaluation problems. Our research draws on the traditional analytic methodology of the Feng Shui model and employs the proposed scheme for solving an actual office layout design evaluation problem. In a comparison of the results of our investigations, a positive numerical evaluation demonstrates the feasibility and efficiency of the proposed scheme, and suggests its applicability with other MCDM problems.
