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.本数据集围绕基于延误的精益绩效评估提供相关研究数据。本研究基于层次分析法（Analytic Hierarchy Process）设计了一份调查问卷，用以评估40种精益工具（Lean Tools）针对四类项目延误源的实施有效性。该调查问卷聚焦于专家对建筑项目延误与精益管理工具的观点、经验及认知。受邀专家需对选定的备选方案（即40种精益工具）进行优先级排序，并大致区分各类工具的相对重要性。本次研究采用层次分析法对各层级内的备选方案开展两两比较，所得相关数据已收录至文件Lean_delay-based_data.xlsx中，该文件包含两两比较矩阵、权重、归一化结果、优先值、随机指数、lambda(max)、一致性指数以及一致性比率。针对每一项准则（即四类主要延误源），研究人员均对作为备选方案的40种精益工具开展了两两比较。研究人员对两两比较所得的权重进行综合处理，并计算其归一化值，以得到各工具对应的特征值。
