| Erection of a built facility means conducting a set of construction processes by crews of various trades. To reduce the construction time, these crews may be scheduled to work concurrently. This requires dividing the whole object (or objects of the investment plan) into work zones. The work zones may be of various shapes and sizes, with the quantities of work related with particular processes not following a clear pattern. Therefore, the duration of work differs process to process and zone to zone, what hinders synchronizing the work of crews and causes idle time of at least some of them. Scheduling often aims at eliminating resource idle time reduce project duration. However, the goals of minimizing the overall construction duration and making a rational use of resources may prove contradictory. It is thus necessary to consider the problem of scheduling repetitive processes in non-uniform work zones a two- criteria optimization problem and search for a trade-off solution. The authors provide a mixed integer programming model of the repetitive processes scheduling problem. In contrast to models presented in the literature, it enables the user to find optimal crew formation modes and, at the same time, reduce the crews’ idle time under the constraint of a fixed project completion date, or to generate non-dominated solutions. The idea is illustrated by a simple case. In the analyzed example, ensuring continuous work of the teams requires the extension of the project duration by 16% in relation to the minimum duration. The possibility of changing crew formation modes helps the planner reduce both the project completion time and the crews’ idle time. |
