| Abstract | ||
| In repetitive construction projects such as roads, pipelines and multi-story buildings, schedulers might need to utilize multiple crews to simultaneously construct sub-activities of a particular activity to shorten their duration. Synchronizing the work of these crews while complying to their work continuity constraint is a challenging task due to the variation of activities quantities of work in each unit and the productivity rates of available crew formations for each activity. This paper presents a novel scheduling approach for repetitive construction projects that enables the concurrent utilization of multiple crews while complying with: (1) crew availability; (2) precedence relationships; and (3) crew work continuity constraints. An application example from the literature is analyzed to validate the current approach, demonstrate its use and illustrate its novel capabilities. Results of this analysis showed that the current methodology successfully saved 8% in project duration in comparison to the least project duration achieved in the literature. | ||
