Environmentally conscious manufacturing and product recovery are considered as an important research in the current business scenario. This is due to the associated costs for virgin materials and waste disposal treatment that have been significantly increased in a yearly basis. Currently, there is a lack of modeling into the problems of remanufacturing production planning with component obsolescence and lifecycle constraints. In practice, the planning decisions may have direct impacts on the amount of wastage and disposal along a reverse supply chain. This article proposes an integrated production planning model with component obsolescence and lifecycle considerations, which helps minimise the total associated costs of production, costs of remanufactured products and components inventory holding, ordering costs, and disposal treatment costs. Numerical examples are also presented to demonstrate this production planning problem for remanufactured products using mixed integer programming optimisation. Finally, several contributions of this study and future works are discussed.
