Modeling and Analysis of Joint Work Package Sizing and Project Scheduling considering Resource Constraints

Abstract: Work package sizing and project scheduling are essential problems in construction project management. In current studies, they are often treated as separate optimization problems. However, in practical situations where resources are limited, there is a growing recognition of the need to integrate these two processes to achieve more efficient and effective project management. This research aims to fill this gap by developing an integer non-linear programming model incorporating work package sizing and project scheduling while considering resource limitations. To evaluate the effectiveness of our model, we utilized Gurobi optimization software to solve nine project instances obtained from RanGen.
