    Field device network buses are a recent application of networks to directly connect factory floor field devices such as sensors, actuators, and operator interfaces over a shared signal medium just as it is done for computers and other office equipment. This is a fundamental change from current practices of point-to-point electrical or pneumatic connection over a dedicated communication medium. Whi... View full abstract»

    For modern enterprises, computer integrated manufacturing (CIM) utilises supervisory control of a large scale real-time system. To be able to implement a supervisory control (dynamical network management), a reduced model of the large scale computing and communication system is a prerequisite. A reduced model is obtained in this work using the cell structure of a modern enterprise, which leads to ... View full abstract»

    Under severe economic situations, the computer systems of companies have to produce new products or to supply new services flexibly to meet the change of market needs as well as customers' demands. To realize a flexible computer system, the system should be able to expand and modify its software as well as hardware rapidly and easily. Moreover the companies have been tackling business process re-e... View full abstract»

    We propose a programmable controller for processing hierarchical structured Petri nets quickly for factory automation systems. System speed is raised by replacing a computer which controls Petri nets with a fast Petri net controller (PNC) by treating a computer and other objects as the same. Each object is described independently, and a system is constructed by connecting them by safe Petri nets w... View full abstract»

    One major challenge of mass customization is how to meet two seemingly conflicting goals, namely satisfying individual customers' needs while keeping mass production efficiency. In order to help customers to select the appropriate product family so that the closest variant can be quickly generated and delivered, this paper proposes a virtual design approach by developing virtual prototypes to repr...

    The Black & Decker factory in Easton, Maryland, now produces many model types in small, infrequent production runs. This has motivated the plant to purchase and install parallel, off-line assembly lines that reduce changeover times. However, the production operators are still using work instructions that are hard to find, hard to interpret, and often outdated. The University of Maryland and Bl... View full abstract»

    This paper presents an efficient approach based on a symbolic method, namely the decision tree learning, to navigate intelligently a robot in a cluttered, unknown and dynamically changing environment. The two major behaviours, namely reactivity and goal-seeking behaviours, are learned from positively reinforced robot motions from a starting point with no rules. The learning emphasis is on the auto... View full abstract»

    In this paper, a new methodology for modeling and simulation of hybrid manufacturing systems is presented. This methodology which is based on an extension of Petri nets can be used to model, simulate and analyze systems with both time and event-driven parts. This new extension is called GPN (global Petri net). Here we show how it is used to model a jobshop at two abstraction levels. At the higher ... View full abstract»

  • Timer error correction method for automatic regeneration of sequential control programs

    Publication Year: 1997, Page(s):485 - 490
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (460 KB)

    It is difficult to replace or maintain many plants that were developed in the 1960s, because the original documents of installed sequential control logics are seldom still in existence. Therefore, our research group has proposed a sequential logics automatic regeneration method with an inductive learning algorithm which we have named SPAIR. SPAIR, however, has certain practical problems. Timer err... View full abstract»

    We have used the term “virtual enterprise” in articulating the 21st century global manufacturing enterprise strategy. One of the key requirements is to design an information system (IS) architecture to control the interoperability of the participated organization's distributed, heterogeneous and concurrent systems. This article presents design of an inter-organizational information sys... View full abstract»

    Winzer and Sitte (1993) and Sitte and Winzer (1994, 1995) modelled enterprise management as a learning control system that has the objective to optimise an enterprise specific comprehensive quality function (CQF). Learning control provides the conceptual framework for a practical decision support system. A key component of the decision support system is an enterprise model. While we investigated m...

    This paper presents the strategies and a design for a scaleable process control system. The strategies include the use of standards, the use of object-oriented design and the use of commercial software packages. The object-oriented design of the process control system took two perspectives: the application and implementation. The layered partition of classes based on these perspectives allows easi...

    Increasingly, automation and computer-based control play key roles in the operation of manufacturing systems. These two factors are necessary to support trends towards greater product customization and increased emphasis on reduction of lead times. At the same time, though, automation and computer-based control can be enormously expensive to design and implement in a factory. These high costs moti... View full abstract»

    The study is based on two assumptions: 1) the child is an active, goal-oriented participant in his or her own development; and 2) physical manipulation of objects is a major contributing factor in the development of cognitive and language skills in a very young child. The CRS robot arm system is used in our study. All the functions are under the control of a computer based software control algorit... View full abstract»

  • Synthesis of locking controllers based on extended net condition event systems

    Publication Year: 1997, Page(s):551 - 554

    In this paper we present an algorithm for controller synthesis for forbidden state problems. We use the approach of previous work but we use an extended model form. In this extended model form based on net condition/event systems the user can connect the signals between the modules with logical operations (AND, OR, NOT). So the modeling is easier and the models are more compact. On the other hand ... View full abstract»
