- Abstract:
During the last decade, evolutionary methods such as genetic algorithms have been used extensively for solving time-cost trade-off (TCT) problems in construction projects. More recently, Ant systems (AS), which are evolutionary methods based on the foraging behavior of ants, have been successfully applied to a number of combinatorial optimization problems. In this article, a formulation is developed that enables AS to be used for the TCT analysis. With its robust optimization search, the AS model minimizes the total project cost as an objective function and accounts for project-specific constraints on time and cost. The findings of this study indicate that AS algorithms are an attractive alternative to meta-heuristic optimization algorithms in the construction engineering and management domain in terms of computational efficiency and their ability to find near-global optimal solutions.
