Cost Optimization Model for Linear Scheduling Problems Considering Work Continuity

For linear construction projects, it has long been known that work continuity is important in improving efficiency. However, most existing scheduling techniques cannot satisfy the need for solving such issues. This paper presents an optimization model for solving linear scheduling problems involving maintaining work continuity. The proposed model adopts constraint programming (CP) as the searching algorithm, aiming at optimizing project total cost. Through cast study, the efficiency of the proposed model is then illustrated.
