The multiple-objective Optimization Algorithm in Construction Project

Time, quality and cost are the three major objectives for project management with mutual strain and influence. To achieve a proper time limit with low cost in high quality is the best solution for a project. The Social Cognitive Optimization is a simple behavioral model based on human social cognition, it shows that it can get high quality solutions efficiently, even only one learning agent, which may be conveniently employed to execute random and global search. The Social Cognitive Optimization (SCO) method is employed to conduct multiple objective project optimization. After introducing the history, the concept and the step of the algorithm, an optimization model is formulated on the time, quality and cost of projects. The actual example indicates that SCO can accurately and efficiently solve multiple-objective project optimization problems.
