Abstrakt: Customer requirements (CRs) are constantly evolving. Products that lack the resilience to accommodate such changes often fail to meet customer expectations, thereby accelerating obsolescence. This study aims to clarify the concept of product resilience towards changing CRs and to develop methods for enhancing it through design. A bi-layer product resilient design framework is proposed, together with a method for enhancing product resilience that accounts for the heterogeneous evolution of CRs. The changes of CRs are first transferred into corresponding changes of design parameters (DPs) through a dynamic domain mapping approach. DPs are then classified into disruptive, mutable, and stable types based on their change characteristics. For disruptive DPs, which change infrequently but exert significant influence, an optimisation strategy is developed to determine appropriate design margins that can buffer such impacts. For mutable DPs, value portfolios are constructed to enable rapid reconfiguration in response to frequent but less severe changes. Finally, the effectiveness of the proposed framework and method in reducing redesign costs and improving product resilience is demonstrated through a case study of a crawler crane.
