Schedule management is a process in which construction projects attach great importance to different stages of a project lifecycle. In Taiwan, the critical path method (CPM) is generally utilized in a project to estimate the duration thereof, but this method is subject to some unsolved restrictions. Thus, some researchers have proposed the earned value management (EVM) method to control the duration of aproject in each stage, and have proven that EVM has a good warning ability of time overrun by forecasting. In recent years, there have been many relative extensions
concerning the index of duration forecasting, and some researchers have compared all methods to find the most accurate one, which is earned schedule management (ESM).
According to the aforementioned, this research will tidy up the restrictions of ESM and then use a simulated project to search for the factors which may affect the accuracy of the ESM-based approach and provide a working rule to users for
reference. Based on the aforementioned simulated results, we use interpolation which is applied in ESM calculation to improve how the existing method’s earned schedule min. (?????) cannot find delay instantly while activity is on a non-critical path. Finally, we look forward and promote project managers applying the improved ESM-based approach to enhance the accuracy of duration forecasting in a construction project. |
