Abstract: In order to satisfy dynamic requirements for product resources in various business processes of Product Life-cycle, a novel product resource whole performance model based on meta-object facility and extension theory was put forward. The model was composed of service demands, service behaviors and product resources. Based on the meta-model architecture, the formalized description of matter-element was introduced into the object-oriented technique to define the constituting elements. And then the standardized constituents were encapsulated to be a reusable integrated unit. The method integrated and promoted the capacity of representation, quick search and encapsulation for the product resource, which highlighted the whole performance of product resource. Finally, a case of service supporting of product resource to the maintenance business was given to verify the feasibility and effectiveness of this model.

Key words: product resource, whole performance, extension meta-object facility, reusable, dynamic service capacity, meta-modeling architecture
