A Remanufacturing Closed-Loop Supply Chain Model Considering Disassembly During New Product Design Stage

The disassembly of waste products is an important part of remanufacturing activities. The difficulty of disassembly has an important impact on the remanufacturing cost, the parts quality and the remanufacturing cycle. It assumes that the original equipment manufacturer (OEM) considers disassembly during new product design stage. Accordingly, it will generate invested costs associated with disassembly level and reduce remanufacturing cost. It sets up a two-stage programming model with constraint to maximize OEM's profit and obtains the optimal disassembly level and optimal pricing strategies by using Kuhn-Tucker condition. It carries out the sensitivity analysis of the decision variables and the objective function by means of analytical methods and numerical examples.
