  1. Development of a FLC Model for Predicting Schedule Impacted by Change Orders in Construction Projects Jieh-Haur Chen Dec. 14 2001

  2. Introduction • Problem Statement • Change orders cause schedule problems raising disputes in construction projects. • Methodology • Find the correlation in historical data. This correlation will be used in establishing a mathematical model, fuzzification, and fuzzy control rules. • Use fuzzy approach to predict and measure construction schedules being impacted by change orders.

  3. Data Analysis • Mechanical and electrical contractors’ roles

  4. Data Analysis • Project Type

  5. Data Analysis • Percent of Change • Public vs. Private (46% vs. 54%) • Distribution of the Percent Change

  6. Data Analysis • Reasons of Change Orders

  7. FLC Model • 5 state variables • Role, Project type, % Change, Feature, And Reasons

  8. Discussion and Future Work • Predicted Schedule = • Yet to process the FLC model successfully. • Fuzzification • Fuzzy rules
