Abstract:ATAG Benelux is a leading supplier of various kitchen appliances and is part of the Chinese multinational; Hisense group. ATAG produces expensive, technological, and high-quality kitchen appliances for its customers. Because of these characteristics, ATAG guarantees their customer ten years of after-sales service (ASS) in which ATAG delivers service parts. However, for one of their products, i.e. the Fusion Volcano (FV) wok burner, ATAG will decide to stop selling the burner due to an introduction of a re-design of the FV wok burner in the market. This means that several agreements between the supplier and ATAG will change when it comes to delivering service parts of the FV wok burner during the ASS period, i.e. ten years of service. Background Both the production technique additive manufacturing (AM) and conventional manufacturing (CM) have a positive result for ATAG during the ASS period. However, ATAG is not familiar with the impact of AM and CM concerning life cycle costing (LCC) and life cycle assessment (LCA) in ASS. The goal of this research is to construct models that can determine the impact of the use of AM and CM during the ASS period through an LCC analysis and an LCA. In this research, we performed a case study for the service parts of the FV wok burner, i.e. the wok head, roast head and burner cup. With the use of the LCA and LCC models where we assess the costs and carbon dioxide footprints, respectively, we can answer the main research question: Under which condition should ATAG use Additive Manufacturing and Conventional Manufacturing to decrease Life Cycle Cost and environmental impact of service parts during the After Sales Service period?
