Recently, due to rise of the couscous of the environmental problem, an engineering designer has to consider not only product model but also whole product lifecycle. The modular design is an important technique to accomplish the each objective such as improving recyclability, reusability and maintainability. But previous work of modular design method has a problem that may search a not feasible modular structure. In this paper, we propose the modular design method considering product hierarchical functional structure. We use hierarchical genetic algorithm to optimize modular structure. Each modular structure is evaluated against criteria such as life span. Our method can search the feasible and adequate modular structure from a number of the feasible modular structure. The proposed method is applied to an inkjet printer to demonstrate its effectiveness.
