Abstract for: Dynamic Analysis of the Workforce Pattern in Construction Process

This presentation shows the analysis of the workforce pattern of a real infrastructural project after its completion. The project is a power plant which required approximately 2000 man months of construction work for a duration of approximately 2 years. The workforce patterns are interpreted according to the System Dynamics (SD). The underlying dynamic hypothesis have led to the identification of a Stock and Flow model of the construction project. The analysis was performed in order to understand the lessons learned i.e. why the actual performance were different from the planned one in terms of time and cost. Moreover the study provides a general modeling method for the simulation of the construction process of any industrial infrastructure. Such a modeling method reproduces the physics of the construction process including mobilization and demobilization of the workforce and the feedback driven recovery actions for the project control. If applied to new projects, the modeling method can allow the Project Manager to develop the risk analysis as well as to be assisted in keeping the performance of the assembly resources close to the planned one during the project execution.
