The reverse Wagner/Whitin model with variable manufacturing and remanufacturing cost

摘要: Abstract In this paper, the reverse Wagner/Whitin model is extended to case with additional variable manufacturing and remanufacturing cost. This can be regarded as a combination of classical pure given returns used products. The combined more appropriate practice, if alternate application processes analysed. For time-constant cost demand data we prove optimality policy starting before switching give an estimation for optimal point. Finally, it investigated how disposal excess inventory would change solution.
