Press release

The assembly of large-scale products is usually organized in the job site principle. For each product, the area requirement increases with the progress of assembly. Therefore a defined area that corresponds to the maximum expansion of the product will be reserved. This results in high area requirements. In this research project a method is developed which allows considering time-varying and competing area requirements in the facility layout planning. Therefore existing optimization models will be expanded and implemented into an heuristic algorithm that will find an ideal layout.

Publications about the project

Whether aircraft, ships or construction machines: The assembly of so-called XXL products requires a lot of space. Researchers at IPH are currently developing a method which enables companies to find an ideal layout. By this means, they can save space and increase their productivity.

XXL products, area arrangement

This article describes the necessity of considering temporal dynamics in the arrangement of assembly areas for large-scale products. This is justified by the fact that the available area represents a bottleneck and thus using of an intelligent arrangement of the areas can lead to an increased utilization of the factory.

XXL-products, assembly area arrangement

The assembly of large-scale products is usually organized in the construction-site principle. For each assembled product, the area requirement increases with assembly time. So for each product a defined area is reserved, that corresponds to the maximum expansion of the product. As the existing area is limited, the single products are competing for it. This results in an increased area requirement and a poor use of area. Therefore time-variable and competing area requirements should be considered in the facility layout planning.
