    Manufacturing systems are changing structure and organisation. 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 tec... View full abstract»

    Investigates a new aspect of fine motion planning for the micro-domain. As parts approach 1-10 μm or less in outside dimensions, interactive forces such as van der Waals and electrostatic forces become major factors that greatly change the assembly sequence and path plans. It has been experimentally shown (Miyazaki and Sato, 1996, and Koyano and Sato, 1996) that assembly plans in the micro-doma... View full abstract»

    The paper describes the concpet of adaptive heuristic assembly planner (AHAP). 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 asse... View full abstract»

    Proposes an architecture for manufacturing enterprises based on the holonic concept. The main advantage of this approach is the decentralised, distributed nature of the system as well as its heterarchic organisation as opposed to the rigid hierarchic and centralised nature of computer integrated manufacturing (CIM). The system models products, resources and tasks and the planning, scheduling and o... View full abstract»

    Manufacturing process planning of the product, especially planning of the bending sequence is the most critical task in designing the press-working line. Three acceleration methods of the bending sequence planning are proposed. First, bending operations in the progressive press-working must comply some topological constraints of a port. These constraints are used as filters for excluding infeasibl... View full abstract»

    For successful assembly of flexible parts, informations about their deformation as well as possible misalignments between the holes and their mating parts are essential. Such informations can be acquired from visual sensors. In the case of deformable part assembly, the corrective assembly motion to compensate for such misalignments needs to be determined from the measured informations. Since this ... View full abstract»

    Industrial schedulers try to take into account more and more complex aspects of manufacturing and become as a consequence more difficult to use efficiently. We suggest a modular framework in order to support the development of schedulers better adapted to the technological constraints of the manufacturing cell they are used in. In order to decrease the time needed to develop such schedulers, an ex... View full abstract»

    One of the main applications of simulation is in manufacturing systems. The complexity of this kind of systems is related to the number of decisions that must be taken in shorter time. The main difficulty is to predict the effects of decisions on the overall system performance. In this context simulation becomes an important tool by means of which it is possible to predict the future performance o... View full abstract»

    The task of handling non-rigid one-dimensional objects by a robot manipulation system is investigated. To distinguish between different non-rigid object behaviors, five classes of deformable objects from a robotic point of view are proposed. Additionally, an enumeration of all possible contact states of one-dimensional objects with polyhedral obstacles is provided. Finally, the qualitative motion ... View full abstract»

    Aerospace is a knowledge intensive industry. The knowledge is dependent on the legacy systems and approaches within the industry. The industry has developed a core competency in aerostructure assembly in the UK. This competency has been developed over many years and from vast experience. This has resulted in a particularly knowledge intensive product development process and placed great dependency... View full abstract»

    Precedence graphs are used in assembly systems design, tasks-to-workstations assignment algorithms and resource planning. Despite that, no systematic obtaining method for these graphs has been proposed. On the other hand, there are very efficient methods to generate assembly sequences and a precedence graph can be obtained by “merging” assembly sequences. In the paper, a property of a ...

    We describe “graspability”, “manipulability” and “virtual gripper”. These concepts are necessary to deal with the geometric relation between a dexterous hand and its grasped object in both the planning and designing processes. Since the coordination of motion of the manipulator and manipulation of its gripper is needed in order to achieve the desired motion of t... View full abstract»
