A Capability Assignment Concept Model for Resource Management System of Product Development

Until recently the major share of the attention of researchers has stayed at process perspectives. The neglect of capability perspectives has resulted in many problems in resource management system. This paper presents a complete capability assignment concept model, called PDRM-CACM, for the resource management system of product development. The model contains eight basic elements (capability, resource, role, activity, administrative role, permission, administrative permission, constraint), and the corresponding relations between the elements. The basic idea behind the model is that resource assignment is actually capability assignment in essential. Thus, we emphasize that the basic element capability must stay at the central position in the model. We specified PDRM-CACM in formal specification language Z in detail. PDRM-CACM is a comprehensive model which integrates role-based access control technology into traditional resource assignment model. At last, we describe the hierarchy operations which provide the foundation of maintaining the concept model.
