Quality gain-loss transmission in dam concrete construction: A CF-GERT-based approach

This study investigates the mechanisms underlying quality loss and compensation in dam concrete construction from both managerial and technical perspectives, presenting an innovative approach to quality control. The primary contribution of this research lies in the integration of characteristic functions into the Graphical Evaluation and Review Technique (GERT), facilitating the development of a quality gain-loss transmission network and enabling network parameter analysis. Additionally, models for identifying and predicting critical paths and processes have been developed. A case study focusing on quality control during the summer construction phase of a hydropower project was conducted to validate the proposed model's effectiveness and rationale. This study aims to offer valuable insights and make a significant contribution to technical advancements in quality control for dam concrete construction.
