A Non-cooperative Game Modular Design Method for Mechanical and Electrical Products for Reuse and Assembly Complexity Balance

doi:10.3901/JME.2025.05.285

Abstract

Abstract: In response to the problems of excessive complexity in reusing and assembling components of waste electrical and mechanical products, which result in low efficiency, high costs, and difficulties in meeting large-scale customization demands, a modular design method for electromechanical products balancing reusability and assembly complexity is proposed to achieve dual optimization of production efficiency and costs. Firstly, the complexity analysis functions for module reusability and assembly are constructed using information entropy theory. Secondly, based on the impact of module reusability and assembly complexity, fuzzy clustering is employed to allocate game strategy. Then, a non-cooperative game optimization model is established, aiming at balancing module reusability and assembly complexity. Optimal decision strategies for all parties are analyzed through game theory. Nash equilibrium analysis is utilized to obtain the optimal module planning scheme and component reuse strategy. Finally, the rationality and effectiveness of the method are validated using the assembly of a fan bearing housing assembly as an example.

Key words: reuse complexity, assembly complexity, non-cooperative game, modularity, information entropy theory
