Applying DEA and Taguchi methods in plant selection and optimal layout to increase commerce management environment quality

Studies have reported that workers of todayʹs businesses spend 80 - 90% of the time everyday in confined working environment. In such environment the air pollution may be 10 times worse than that outdoors, with various organic compounds polluting the air, leading to increasingly compromised health in workers and work efficiency, which decrease the commerce management efficiency and marketplace competitiveness. Many studies testified that plants disposed in commerce management environment are effective in cleansing the air and help release pressure off business workers. Hence, the present research applies Data Envelopment Analysis, DEA, to the selection of indoor plants that can decrease air pollution, mitigate anxiety and increase work efficiency, also identifies the combination of plant dispositions with optimal parameter design by Taguchi method. Whereby, this paper proposes concrete recommendations as reference for enterprises to create a comfortable, elegant, refreshing and healthy commerce management environment, while building a measuring model to further enhance the management efficiency and marketplace competitiveness for enterprises.
