Disassembly Line Planning Through the Generation of End-of-Life Handling Information from Design Files

Abstract Disassembly is an important aspect of end of life product treatment, encompassing the fundamental processes related to recycling and reusability of products and their components. However, due the diverse amount product types that dismantling centers treat, disassembly lines have need of high flexibility, especially regarding the time required for planning or configuration. This paper presents a method for the generation of disassembly related information from product design files as well as their use for disassembly line planning. The core of the method is based on a disassembly precedence diagram generation algorithm that can generate relevant disassembly information having as direct input product files. Moreover, a method for the estimation of disassembly process times is presented that can further enhance this information so that they can be used for disassembly line planning. The proposed method is presented through an industrial case study concentrating on the generation of disassembly information from an automotive differential CAD file.
