A Simulation-Based Optimization Approach for Assessing Sustainability in a Multi-construction Projects Environment

摘要

Sustainability development has become widely applied specially when considering construction projects as a result of the huge leap in the global urbanization rates. Researchers are continuously attempting to find accurate and reliable sustainability construction performance measures. However, the majority of these researches focus on studying the sustainability in a single construction project, although it might be worthwhile studying sustainability in multiple construction projects in order to maximize the overall sustainability. In this paper, the authors developed a simulation optimization model using simulated annealing for scheduling the different phases in their right sequence of multi-construction projects while maximizing the overall sustainability. The previous is done while assessing the sustainability development and simulating the effect of external factors such as technological advancement and change in people's perception on sustainability measures. Results showed that considering scheduling in multi-construction projects increased the overall sustainability performance compared to unscheduled ones.
