Flexible systems anchored to the ground are low visual impact alternatives to be used in slope protection. With the aim of reducing their installation time and costs the mechanical union between layers of membranes is proposed to be done in warehouses instead of independent installations on site. The most appropriate component selection and linking method is selected using multi-criteria decision analysis, specifically using AHP, WASPAS and TOPSIS techniques. The criteria considered in order to take the decision are cost of materials, ease of sewing, transport and installation of the system, biodegradability of the secondary mat and its hydroseeding retention capacity that stimulates the revegetation. Due to the uncertainty on the data of biodegradability, four scenarios were analysed. The results indicate that the most suitable secondary membrane in all cases is the coconut fibre mesh and should be connected to the main membrane using a cable tie machine.

使用多准则决策分析减少安装时间的边坡稳定系统中膜和连接方法的选择

固定在地面上的柔性系统是用于斜坡保护的低视觉影响替代方案。为了减少安装时间和成本,建议在仓库中完成膜层之间的机械结合,而不是在现场独立安装。使用多标准决策分析选择最合适的组件选择和链接方法,特别是使用 AHP、WASPAS 和 TOPSIS 技术。为做出决定而考虑的标准是材料成本、系统的缝纫、运输和安装的便利性、次生垫的生物降解性及其刺激重新植被的水播保持能力。由于生物降解性数据的不确定性,我们分析了四种情况。
