A market-oriented deterministic dynamic product recovery problem and its multi-echelon model formulation are discussed in this paper. For this general non-linear alternate deterministic dynamic product recovery model a dynamic programming solution procedure is developed. Furthermore, the subcases of the Just-in-time situation with regard to the suppliers as well as customers are considered, for which the two-stage problem is transformed to easily solvable one-stage models. It will be seen that the regarded recovery problem in this formulation is just a special multi-echelon problem with two alternative production options.

As we could show the market-oriented dynamic recovery model can be regarded and formulated as a special multi-echelon problem. We have developed a solution procedure for a general non-linear alternate deterministic dynamic product recovery model, based on Wagner/Whitin algorithm. While in former models the property of having recovery before production holds, this characteristic is lost in the regarded supplier and customer JIT cases.
