Highway construction projects, due to the frequent repetition of many of the activities and buildings during the execution process, are known as linear-repetitive projects. In this projects work Interruptions and resources unemployment is causing time and cost waste. So scheduling as result to reduce time and cost waste, is extremely important. The proposed method in this study to scheduling optimization of highway construction projects is based on one of the principles of lean thinking in removal of the wastes (Muda). And Genetic Algorithm and NSGAII approach has been used to solve scheduling problems. Given that in many cases because of uncertainties in terms of project, time and cost of the activity can not determine conclusively, thus it is seen based on fuzzy approach to this problem too. The main advantage of this method is the special attention the continuity of work between units, so that work interruptions and the resources unemployment reduced to the lowest possible. Thus reducing of wastes, project will be closer to lean construction.
