Abstract
Continuously changing business environments require Enterprise Resource Planning (ERP) systems of modern manufacturing enterprises have the ability of agile reconfiguration to adapt to changes with quick responses. Based on a deep analysis of benefits that component technology provides to agile reconfiguration, the paper presents the architecture of component-based ERP systems in which the high efficiency for system construction and reconfiguration is supported by multiple grained component coexistence. A unified feature-oriented component model and the full life cycle of component-based ERP are then presented, and the paper expatiates on the process and artifices of ERP agile reconfiguration based on component reuse, with emphasis on component matching and selection problem, in which an approximately optimal component set is chosen from a component library by minimizing the matching cost to adapt to changes. Finally a practical case, i.e. reconfigurations on a production planning system, is put forward to validate the effectiveness of this method.
