Abstract：The multimode resource-constrained project scheduling problem (MRCPSP) is an essential mathematical model for construction schedule optimization. However, such models cannot easily simultaneously represent multiple relationships between activity duration, cost, and resource requirements. This paper presents an MRCPSP model that includes multiple relationships that is solved using constraint programming (CP). The model represents the relationships between activity duration, cost, and resource requirements by introducing a productivity function and the total resource requirements for combinations of activities. The model can simulate the construction productivity changes and the influence of construction methods on the results. The results then have a more explicit engineering meaning to improve actual projects than the traditional MRCPSP.
