Constraint-based simulation of outfitting processes in building engineering

Abstract: Execution planning of building projects is very time-consuming. A multitude of requirements such as local, technical and specific project ones have to be considered. This results in a wide choice of possible schedules including the assignment of employees and equipment. Often these different solutions are not sufficiently analysed in building industry. However, an in-depth investigation of different solutions is very useful not to overrun the projected costs and scheduled time. This paper focuses on using a constraint-based simulation model to detail construction tasks and their corresponding prerequisites such as constructional dependencies between tasks, necessary resources or availability of working space to execute a given task. Adjustable simulation components are developed to be combined to a thorough simulation model. By using the composed simulation model practical schedules can be generated and evaluated in terms of work flow organisation, utilisation of space and worker’s efficiency as well as process costs.

Keywords: constraint-based simulation, outfitting processes, construction schedules, resource assignment
