Earned value management (EVM) was originally developed for cost management and has not widely been used for forecasting project duration.
In addition, EVM based formulas for cost or schedule forecasting are still deterministic and do not provide any information about the range of possible outcomes and the probability of meeting the project objectives.
The objective of this paper is to develop three models to forecast the estimated duration at completion.
Two of these models are deterministic; earned value (EV) and earned schedule (ES) models.
The third model is a probabilistic model and developed based on Kalman filter algorithm and earned schedule management.
Hence, the accuracies of the EV, ES and Kalman Filter Forecasting Model (KFFM) through the different project periods will be assessed and compared with the other forecasting methods such as the Critical Path Method (CPM), which makes the time forecast at activity level by revising the actual reporting data for each activity at a certain data date.
A case study project is used to validate the results of the three models.
Hence, the best model is selected based on the lowest average percentage of error.
The results showed that the KFFM developed in this study provides probabilistic prediction bounds of project duration at completion and can be applied through the different project periods with smaller errors than those observed in EV and ES forecasting models
