Data for risk-based lean performance assessment

This dataset presents a delay-based lean performance assessment. A survey was designed based on analytic hierarchy process algorithm to measure the effectiveness of forty lean tools on four project delay sources. The survey focused on experts’ opinions, experiences and knowledge of construction project delays and lean management tools. The experts were asked to prioritize the selected alternatives (lean tools) and to distinguish in general the tools which are more or less important. The alternatives in each level were compared with each other using analytic hierarchy process and the values obtained are highlighted in one file (Lean_delay-based_data.xlsx) containing pairwise comparison, weights, normalization, priority values, random index, lambda(max), consistency index and consistency ratio. For every criterion (four main delay sources), pairwise comparisons were made for the alternatives, that is, forty lean tools. Synthesis of the weights from the pairwise comparisons was undertaken and their normalized values were calculated to obtain their respective eigenvalues.

本数据集展示了一种基于延迟的精益绩效评估。该调查基于层次分析法算法设计，旨在衡量四十种精益工具对四个项目延迟来源的有效性。调查侧重于专家对建设工程延迟以及精益管理工具的意见、经验和知识。专家被要求对所选备选方案（精益工具）进行优先级排序，并在总体上区分工具的重要程度。每个级别的备选方案之间通过层次分析法进行比较，其获得的价值在一份文件（Lean_delay-based_data.xlsx）中被突出显示，该文件包含成对比较、权重、归一化、优先值、随机指数、λ(max)、一致性指数和一致性比率。对于每个标准（四个主要延迟来源），对备选方案（四十种精益工具）进行了成对比较，并进行了权重合成，计算其归一化值以获得相应的特征值。
