N2 - Multiple shifts are often utilized in construction projects to accelerate schedules. Despite its advantages, the utilization of multiple shifts in construction often suffers from a number of limitations including additional acceleration costs and productivity losses. This paper presents the development of a multi-objective optimization model for scheduling multiple shifts that is capable of generating optimal tradeoffs among (1) minimizing the project duration; (2) minimizing the project cost; and (3) minimizing the utilization of evening and night shifts. An application example is analyzed to illustrate the use of the model and demonstrate its capabilities in generating optimal schedules and labor utilization plans for the day, evening, and night shifts.
