Abstract For many construction projects, the contractor pays delay penalties if the project is delayed. Therefore, it is very important to finish projects in the shortest time possible. Goldratt 1997 suggested critical chain project management method (CCPM) as an attempt for minimizing project duration. Goldratt approach and other buffer sizing approaches are different and not specific for project types which do not satisfy construction projects circumstances. The proposed model uses multiple shifts and discrete relationship between activity time and cost to be solved by integer programming to express real-life construction projects, optimize project duration with minimum cost and overcome Student’s Syndrome and Parkinson’s Law. Constrained related activities in shifts are used to overcome multitasking. A simplified representation of a small example project is formulated to represent this model. Furthermore, study cases are used to check the model results. Final solution shows that this method is simple and generates a shorter time at low cost. |
