Nondominated Archiving Genetic Algorithm for Multi-objective Optimization of Time-Cost Trade-off

Abstract:- Construction planners are encountered with challenge of optimum resource utilization to compromise between different and usually conflicting aspects of projects. Completion date and cost if project are among the crucial aspects of each project. Such problems are difficult to solve because of not having unique solutions. For time-cost optimization problems, as combinatorial optimization problems one can apply heuristics or mathematical programming. In this paper, a new improved multi-objective Genetic algorithm is used to solve the time-cost trade-off optimization problem. An 18 activity example is analyzed to illustrate its capabilities in generating optimal/near optimal solutions
