Abstract: The efficient allocation of different types of resources in large-scale construction projects is a key issue that the project management theory and practice facing nowadays. Especially both the work operability, which including the process sequences and time interval, and the feedback impact of these resources are considered. Combining the earned value method and the system dynamics theory, this paper establishes a system dynamics model of multiple resource allocation of large-scale construction projects. The modeling is based on the causal analysis between the resource availability and the work operability. Major investment construction projects statistical data in Shanghai are used to set the model parameters. The simulation results indicate that there is significant difference on the allocation importance and systematically affect of different resources in construction projects. Both the project operation model and multiple resource matching should be considered when resource allocation strategies are developed. Mismatch of resources always result in unsteady of the resource allocation system or strategy failure. This research will provide theoretical reference and practice support to the further research on multiple resource allocation of project management.
