Abstract: The multimode resource-constrained project scheduling problem (MRCPSP) deals with the scheduling of a set of projects with alternative requirements of renewable and non-renewable resources. Solutions to the MRCPSP usually consider objectives in terms of cost and time. However, social objectives related with the workforce may impact the performance of projects and affect program sustainability goals. To account for this new social input, this paper extends the MRCPSP and proposes a new multiobjective mixed-integer programming model. The proposed solution method uses an a priori lexicographic ordering of the objectives, followed by an ɛ-constraints approach. The model is illustrated with a case study of a construction program.
