Variance Analysis on Regression Models for Estimating Labor Costs of Prefabricated Components
Publisher: ASCE
Abstract: Regression modeling has been based on analyzing error terms between the predicted output and the target output without addressing the variance of the predicted output and the impact of individual input parameters on the ...
Global Sensitivity Analysis Methodology for Construction Simulation Models: Multiple Linear Regressions versus Multilayer Perceptions
Publisher: ASCE
Abstract: In this research, the multilayer perceptron (MLP), also known as error backpropagation neural networks, is made transparent and explainable by contrasting with the commonly applied multiple linear regression (MLR). A novel ...
Mitigating Project Schedule Risks by Identifying Subcritical Paths and Variance-Critical Activities
Publisher: American Society of Civil Engineers
Abstract: Significant risks in project completion delay could be buried in the development of project schedules because of theoretical flaws in project schedule risk analysis. Major project delays hamper infrastructure development ...
Error Propagation Model for Analyzing Project Labor Cost Budget Risks in Industrial Construction
Publisher: ASCE
Abstract: Industrial construction employs various trades in large-scale prefabrication operations to produce modules and structural components at an offsite facility that will be shipped to the field for rapid installation. Developing ...
