Identification of rework station location to enhance reworkability using design for disassembly

Juan Alejandro Saavedra, University of Texas at El Paso


Rework stations are commonly established as part of each assembly stations causing the material flow of the process to be constantly interrupted. Another option is to place the rework station at the end of the production, but this is not cost effective. This breakeven point between reworkability and cost methodology has been proposed in this thesis to identify the location of a single rework station in an assembly line in order to enhance reworkability using the Design for Disassembly (DfD) principles. The methodology uses the 17 guidelines of DfD in a manufacturing scenario in order to propose a reworkability index of a product. This index is compared to cost index in order to find their breakeven point. This breakeven point allows the methodology to identify a location in the assembly process for the rework station in order to find a balance between these two factors. The methodology proposed is a series of simple step that can allow a company to reduce extra work and improve material flow by establishing one rework station in any production line.
