ENHANCEMENT OF SCHEDULING RELIABILITY IN BUILDING PROJECT USING THEORY OF CONSTRAINT

概要

Most building projects neglect that despite minimizing the project duration, the uncertainty of constraints, such as the uncertainties of personnel, machine, or weather still jeopardizes the project scheduling reliability and influences the resources arrangement causing the project duration overrun. The contractor must combine the project scheduling with planning to reduce the uncertainty of the project activities and project duration. This study attempted to improve the relationship between activities, revise the uncertainty of activities, and reduce the uncertainty of schedule to enhance the reliability of building project scheduling by applying the concepts of Theory of Constraint (TOC). To demonstrate the effects on the reliability improvement in building project scheduling by the application of TOC, the authors take one high-rise building constructed in Taiwan as a case study to illustrate enhancement of scheduling reliability. The simulation results are compared to Program Evaluation and Review Technique (PERT) simulation. The comparisons illustrate that the DBR proposed model can enhance the reliability of schedule planning.
