Supply chains are evolving to more coupled organisations like virtual enterprises, though maintaining the single entities autonomy, adaptability and dynamism properties. Such organisations imply organisational and technological shift through agility, distribution, decentralisation, reactivity and flexibility. New organisational and technological paradigms are needed in order to reply to the modern manufacturing systems challenges. The paper proposes and justifies the holonic manufacturing system concept as the main organisational paradigm presents the infrastructures needed to assure system operation, security, coherence and coordination. Additionally, the scheduling sub-system is presented along with a scheduling method developed as a case study.","PeriodicalId":326575,"journal":{"name":"Proceedings of the 1999 IEEE International Symposium on Assembly and Task Planning (ISATP'99) (Cat.

Visual servoing techniques have shown great promise as a control strategy capable of submicron precision while compensating many of the problems that exist in the micro domain, including thermal expansion of assembly devices and imprecisely modeled and calibrated sensors and actuators. This project develops rules for micropart design to aid in device assemblability with visual servoing techniques by ensuring that the microparts can be easily tracked and controlled using vision feedback. A criterion is presented that estimates part trackability based on the visual appearance of the part. This criterion is then used to microfabricate features to improve part trackability and hence, the assemblability of the device. The criterion considers the feature appearance when the part lies out of the optical system's depth of the field. A Fourier optics based approach is used to simulate the visual appearance of microparts represented by CAD models using high resolution optical systems. This simulation is used to automatically design microfabricated features on microparts.","PeriodicalId":326575,"journal":{"name":"Proceedings of the 1999 IEEE International Symposium on Assembly and Task Planning (ISATP'99) (Cat.

The modeling process uses the concept of virtual joints associated with the toleranced functional elements in a tolerance chain. These virtual joints simulate small possible dispersions of the toleranced functional element in terms of three general small translations and three general small rotations assuming to result from manufacturing inaccuracies. Using standard Jacobian-based computations, it becomes possible to model the effects of such small dispersions of each element in a kinematic chain around a point of interest on an assembly, in particular around the desired functional requirement. The main focus in the paper is on the important ability of the developed tolerance model to explicitly include the effects of dispersions on two types of functional element pairs in a chain around a functional requirement, namely internal pairs (pairs on the same part) and kinematic pairs (pairs on different parts in contact).","PeriodicalId":326575,"journal":{"name":"Proceedings of the 1999 IEEE International Symposium on Assembly and Task Planning (ISATP'99) (Cat.

AHAP has the ability to automatically extract specific knowledge about the assembly from previous planning sessions and the ability to use this constructed knowledge for guiding future planning sessions. The benefits of such a possibility are increased efficiency, since the experience would help to find the optimal assembly sequence more quickly, and the increased flexibility would allow the planner to learn and use different knowledge representing a different set of criteria in its search. In addition, availability of the knowledge base and the possibility of its refinement would enable the humans to get insight into the influence of used parameters on planning, and would enable them to tune the planner to their specific needs.","PeriodicalId":326575,"journal":{"name":"Proceedings of the 1999 IEEE International Symposium on Assembly and Task Planning (ISATP'99) (Cat.

SC is a joining process between the tool and object, leading to a strong form closure to transmit forces and torques. It is shown that the SC can overcome some disadvantages of frictional contacts. The difference between self-connection and assembly connection is analyzed in detail. With SC integrated, the disassembly task is decomposed into three processes: 1) self-connection process; 2) task execution process, and 3) separating process. Consequently, the SC behaves like catalyst, which efficiently reduces the difficulty of the disassembly task. The proposed approach is being applied to the dismantling of loose connections. An example is given to show its effectiveness.","PeriodicalId":326575,"journal":{"name":"Proceedings of the 1999 IEEE International Symposium on Assembly and Task Planning (ISATP'99) (Cat.
