The Application of Modularization Concept for Redesign of Panasonic KX – 2315 Product Based on Design for Remanufacturing (DFR) and Design for Disassembly Criteria (DFdA)

Abstract

Abstract. Modular product is defined as product consists of detachable modules, which can be manufactured, assembled, and serviced separately. Modularization components of a product into modules can be done based on several criteria. Design for Remanufacturing (DFR) and Design for Disassembly (DFdA) criteria is being used in this research. The DFR criteria are related to the stages of remanufacturing a product when it has reached its end of life cycle. The first stage of remanufacturing is disassembly. Therefore, the DFdA criteria, which is related to the easiness of product disassembly is also being used. The object of this study is Panasonic KX – T2315 telephone. Modularization process is carried out by identifying the values of the relationship between each part of product based on the DFR and DFdA criteria. These values are structured into an interaction matrix and then will be grouped into modules using two clustering method, Hierarchical Clustering Algorithm and Quadratic Programming Model respectively. For both clustering method, the recommended number of modules are 5 modules. Those modules consist of grouped components that perform certain functions and objectives. The clustering result from both clustering method was compared, and the best result was chosen to be the final module recommendation.
