Product Life Cycle Energy Consumption Analysis Method Considering Remanufacturing

The product life cycle energy consumption model was established considering the impact of remanufacturing on the product lifecycle, and the energy consumption quantitative method was given. In order to optimize the life of a product, a method to calculate its life cycle critical point was proposed. The energy consumption model was applied to two types of gearboxes, new and remanufactured, to compare their life cycle energy, and the energy-saving design scheme optimization was achieved.
