Abstract

End of life disassembly is an important process that can be used to make available the parts of a product for different material and part recycling processes at end of the product’s useful life. However, the efficiency of the disassembly process greatly affects the economics of meeting the environmental goals set for the product. An important determinant of the disassembly efficiency is the product configuration. Therefore, it is essential that these implications of the configuration be assessed and modified during the design stage itself. To support this design effort a formal model called the Configuration-Value (CV) model is proposed to evaluate and analyze the effect of product configuration on end-of-life disassembly. This model focuses on the rate of value extraction during the disassembly process and can be used to identify the critical bottlenecks in the configuration that need rectification by design. An example is presented to demonstrate the application of the proposed model.
