Värdeflödesanalys i försörjningskedjan : Balkhantering på Lättelement AB

Sammanfattning: The project-based culture of the construction industry is a challenge to overcome. As a customer, great flexibility is expected with variations in design as needed and design. Being able to meet these expectations and at the same time have efficient flows with as little waste as possible is complex. Productivity is considered to be significantly higher in the manufacturing industry with its developed methods inspired by Lean. One of these methods is to create efficient flows that have been shown to remove some of the built-in waste that may exist and thus create opportunities for increased productivity.   Lättelement AB that this study is done in collaboration with projects and manufactures prefabricated building elements based on the customer's wishes with built-in wood-based light beams purchased from the supplier Masonite Beams. The packages with the wood-based light beams require large spaces in layers and in connection with both the layer and its handling there are unnecessary wastes. Developing flows by applying parts of the Lean principles can be a way to increase productivity and reduce waste. Therefore, the purpose of this study is to investigate opportunities for reduced inventory by exploring the potential of a developed flow of wood-based light beams in the supply chain. The goal is to present a proposal and action plan for an improved flow of wood-based light beams that may be linked to layer and its built-in unnecessary wastes.    This qualitative study has been carried out through observations and interviews to investigate the current situation. Furthermore, representatives from each company have been gathered in a workshop to discuss a future situation.   The results show that it is possible to reduce waste in the form of layer, rework and waiting through developed work in the supply chain between Lättelement AB and the supplier Masonite Beams AB with a focus on the common material and information flow. The study shows that a change in ordering routines through early order reservations with later calls, compatible order files and more project-specific orders can contribute to increased productivity and reduce the built-in unnecessary wastes.   This work thus demonstrates the potential of working with value flow analyses in the supply chain as a relatively simple method in the construction industry to increase productivity.
