Nowadays,human production and life have a great impact on environmental degradation,and the design and production of products account for a large proportion,which has attracted extensive attention from academia and industry.However,considering the environmental problems,few studies involve the joint optimization of product family architecture and its whole life cycle process configuration.In addition,in previous studies,the hierarchical characteristics behind the two optimization problems and the complex interaction between product family architecture,whole life cycle process configuration and environmental problems have not been revealed and solved.Therefore,this paper studies the joint optimization between the modular architecture of product series considering carbon emission and the whole life cycle process configuration.Based on the above analysis,this paper first studies the modular design of complex products,provides a theoretical premise for the modular architecture of product series,and puts forward the method of module division by using product function,structure,materials and recyclability factors according to customer needs.In the method,the product decomposition model is established based on FBS mapping to determine the relationship between product function and structure,and then the relevant comprehensive matrix is established according to the relationship between module division driving factors.Then the improved nsga2-fcm algorithm is used for cluster analysis to realize product module division,and the performance of the algorithm is compared and analyzed to prove the effectiveness of the algorithm.In addition,in order to solve the problem of sustainable design of product series,product design and whole life cycle process configuration are considered to meet the requirements of sustainable design of products.This paper conducts a sustainable research on the joint design between the modular architecture of product series considering carbon emissions and the process configuration of the whole life cycle,and proposes a two-tier game model research method to coordinate the modular architecture of green product series and the process configuration of the whole life cycle,In the method,firstly,a joint optimization framework and a master-slave interactive decision-making mechanism for the modular architecture of green product series and its green life cycle process configuration are proposed.The product designer decides to optimize the modular architecture of green product series at the leadership level,obtains the modular architecture design scheme of green product series from the perspective of economy and society,and selects components,modules and product types for the design scheme,So as to maximize product profit and green degree.As a follow-up layer optimization problem,the green full life cycle process configuration is decided by the producer.According to the design scheme of the leadership,environmental constraints are added to determine the optimal realization process of the production process,module manufacturing process,product assembly process,product recovery and treatment mode and product transportation mode of each component candidate,so as to minimize the cost of green full life cycle process configuration.According to the proposed master-slave interaction mechanism and based on the game theory,this paper establishes a double-layer multiobjective optimization mathematical model,and designs a double-layer non dominated sorting genetic algorithm II to solve the double-layer multi-objective optimization mathematical model,so as to obtain the Pareto optimal solution of the model.Finally,taking the beer fermentor as an example,the feasibility and potential of the modular partition method,bilevel programming model and bilevel non dominated sorting genetic algorithm-II proposed in this paper are verified.The results show that carbon emission has a significant impact on the structure of the optimal green product series and the allocation decision of green life cycle process;Integrating the awareness of product sustainability into product series development activities is conducive to enterprises to improve profits and competitive advantage;In addition,the model proposed in this paper can well deal with the conflict and coordination between the architecture of green product series and the process configuration of green life cycle,and well balance the environmental impact caused by enterprise interests and development activities.
