Titel
An integrated approach for object-oriented assembly system planning and assembly control
Abstract
Characteristics such as decentralized, autonomous, self-planning, self-controlled, and teamwork describe the trends or the nature of modern assembly systems which are usually hybrid. These accompanied with the continuously increasing number of variants and shorter product life cycle require reusable assembly units which are flexible and modular, as well as an efficient job order processing. The system should be free configurable based on the new product structure and features, and the assembly control must integrate the available information used and generated the system planning. This paper presents an integrated approach, starting from product structure to design an object-oriented assembly system model, and based on this computer-internal model to control the assembly sequence and operation according to the job orders. The characteristics of modern assembly will be summarized. The requirements on the planning of such an assembly system and assembly control are postulated. An archite cture for integrated assembly system planning and control will be described. The objects for such a system are then derived. The applicability of this approach will be shown on a concrete example of a subassembly from a transportation vehicles manufacturer.
