Optimization of Work Schedules Executed using the Flow Shop Model, Assuming Multitasking Performed by Work Crews

Abstract

The problem described in this paper deals with construction project scheduling for multi-object projects. The use of the flow shop model allows for quick execution through optimal, simultaneous means of production. The correct order of tasks according to assumed criteria is the subject of a lot of research. In this paper, we have focused on the aspect of multi-project work crews. In practice, we often observe cases where overburdened crews are supported by ones with downtime. This paper presents a newly developed model used to smoothe out schedules in terms of maintaining crew work continuity. A full description of the algorithm and example usage are presented.
