Abstract
Today many Engineer-to-Order (ETO) companies are under pressure to reduce their costs while minimizing the completion time on-site. ETO companies have worked in recent years to industrialize their manufacturing processes and to introduce prefabrication by standardization and modularization of their products. Less emphasis was set on organizing in an efficient way the installation supply chain. Considering tier one suppliers, which deliver their products to a building site for assembly, manufacturing should be driven according to the demand needed on the building site. Finished parts should be transported to the construction site Just in Time (JIT) with short lead times and low stocks in the fabrication shop and on-site. This requires for both, the construction site and the fabrication shop, a synchronous production and assembly planning. Therefore, an on-site oriented capacity regulation for fabrication shops is needed for ETO companies.
