Soft Constraint‐based simulation of execution strategies in building engineering

In building engineering different strategies can be used to schedule the execution processes of building projects. Currently, these strategies have not yet been sufficiently formalized, and considered for construction scheduling. This paper presents a concept for modelling and simulating execution strategies by using Soft Constraint representations. In particular, the GRASP heuristic is applied within a constraint-based simulation approach to improve construction schedules by observing well-established execution strategies. The benefits of this concept are shown for the strategies Avoid Soiling and Human Strain Factor.
