Abstract: Rescheduling of production schedules of precast elements is often necessary due to various causes arising from both on-site and factory conditions. Ideally, rescheduling should take into account resource and schedule constraints both in the factory and on-site. The priorities and objectives of factory and site managers are likely to differ and may well conflict with one another. This paper develops a multiobjective optimization problem associated with the rescheduling of precast production and demonstrates the use of a genetic algorithm-based procedure to search for solutions. Results obtained from an example considering two objectives indicate that the proposed production rescheduling procedure can identify a Pareto-optimal front of good quality solutions which can be used to facilitate the decision making process.
