A Sustainable Product Multi-Platform Planning Model for Assembly and Disassembly Process

The development of a product platform is an effective strategy to respond to dynamic market demands, decrease lead time, and delay product differentiation. However, the traditional product platform configuration method cannot satisfy the sustainability requirements for modern products. To solve this problem, a sustainable product multi-platform (SPMP) model for assembly/disassembly technology is proposed in this article. The proposed SPMP model measures the energy consumption of module instances during the installation based on the platform-based assembly index (PAI) and platform-based disassembly index (PDI), and provides a multi-platform solution for the assembly of the product family. To demonstrate the effectiveness of the proposed method, two product family cases are discussed. A simplified case shows that multi-objective particle swarm optimization (MOPSO) algorithm has a stronger optimization ability than the linear programing method in reducing the product processing cost. The hair dryer family case demonstrates that the proposed method reduces the energy consumption during assembly by linking sustainability to the product design.
