Abstract: Product design for remanufacturing is a combination of designing processes whereby an item is designed to facilitate remanufacture. Design for remanufacturing is guided by an assessment of product or component value over time. This value may vary depending on the market and market demand and supply, legislation and technological improvements. Obviously the goal of design for remanufacturing is to improve manufacturability. Through this project we aim to study the various key parameters which needs to be considered for optimum designing of a new product or an existing product from the view of remanufacturing. Technology and Economic model will are developed using these key parameters for the selective components and they are employed for coordination and testing via simulation, finally with the solution of the updated parameters design of upadation can be accomplished.
