  • formal approach to include a human material handler in a Computer Integrated Manufacturing cim system
    International Journal of Production Research, 2007
    Co-Authors: Bertan Altuntas, Richard A Wysk, Ling Rothrock
    Abstract:

    Formal modelling techniques that employ principles of finite state automata have been increasingly used for shop-floor control. These approaches have focused primarily on unmanned systems where the self-contained logic for control of the systems is embedded within the model(s). To date, human operators are seldom configured within the modelling detail required for these systems. The result has been that the interface of humans within automatic systems has been limited. In general, humans performing physical activities in an automatic system must mimic the detailed responses normally transmitted via control Computers and equipment, making the human interaction painful and prone to error. This paper discusses (1) the formal modelling specifics required for the control of such an automated shop floor system; and (2) the role and interactions of the human primarily in automatic systems. The human in the automatic Manufacturing system addressed here serves primarily as a material handler and material transport...

  • process planning interface for a shop floor control architecture for Computer Integrated Manufacturing
    International Journal of Production Research, 1995
    Co-Authors: S Lee, Richard A Wysk, Jeffrey S Smith
    Abstract:

    Many researchers have developed ‘standard’ Computer-Integrated Manufacturing architectures in order to reduce the cost associated with software development and maintenance. Since a process plan provides the principal input to a Shop Floor Control System (SFCS), it is necessary to provide the process plan information in a manner suitable for use by the SFCS. However, research in interfacing process planning with different SFCSs has been extremely limited. The reason for this is that proper integration hooks and a generic vision for process plans do not exist. A deterministic description of what process plans are, and how they should be represented is yet to evolve. We describe an information interface between process planning and shop floor control. The functionality, scope, and information content of process plans are discussed in order to provide a clear functional distinction between process and planning and shop floor control. An information architecture for interfacing process plans and SFCSs built. T...

  • a shop floor control architecture for Computer Integrated Manufacturing
    Iie Transactions, 1996
    Co-Authors: Jeffrey S Smith, Walter C Hoberecht, Sanjay B Joshi
    Abstract:

    The evolution to Computer-Integrated manufacture (CIM) has been slower than expected. This can be attributed directly to high software development and maintenance costs and the difficulty in achiev...

  • a shop floor controller class for Computer Integrated Manufacturing
    International Journal of Computer Integrated Manufacturing, 1995
    Co-Authors: Jeffrey S Smith, Sanjay B Joshi
    Abstract:

    Abstract Computer-Integrated Manufacturing (CIM) has not yet provided the expected benefits for small-to-medium volume discrete parts Manufacturing operations. Typically, these systems come in over budget and yet do not provide the promised flexibility. This can be directly attributed to the high cost of control software development for Integrated systems. Reusable software has been proposed as a solution to the high software development and maintenance costs. One paradigm for reusable software, object-oriented modeling and programming, has emerged as an important method for specifying, creating, and reusing software modules. This paper describes an object-oriented approach to specifying and developing shop floor controllers for automated Manufacturing environments. Specifically, a shop floor controller class hierarchy has been developed based on the behaviour of specific shop floor equipment and is described in this paper. User experience has shown that software development time can be significantly redu...

  • Computer Integrated Manufacturing a taxonomy of integration and research issues
    Production and Operations Management, 2009
    Co-Authors: Dharmaraj Veeramani, John J Bernardo, Chen H Chung, Yash P Gupta
    Abstract:

    The past decade has seen an upsurgence in the number of Manufacturing companies that are attempting to transform into Computer-Integrated enterprises. However, much of the Computer-based integration efforts in these Manufacturing organizations have been limited in scope and localized within certain areas of the organization (particularly, technology-intensive areas such as the shop floor). Such compartmentalized and myopic approaches to the development of Computer-Integrated Manufacturing (CIM) systems undermine the ability of these systems to reach their fullest potential. CIM is much larger in scope and can impact an organization along various dimensions and at various levels. The fact that no completely Integrated Manufacturing enterprise has been developed to date can be attributed, in part, to a lack of understanding of the scope and implications of CIM. The purpose of this paper is, therefore, twofold. First, the paper presents a meta-schema (called TRIAD) for multidimensional and multilevel integration of a Manufacturing system. Second, on the basis of the proposed meta-schema, the paper develops a taxonomical framework for defining key integration issues in CIM system design and discusses critical research needs that exist in this area. It is hoped that this paper will serve as a road map for research efforts that will enable the emergence of comprehensive CIM systems.

  • the purdue enterprise reference architecture
    Computers in Industry, 1994
    Co-Authors: Theodore J Williams
    Abstract:

    Abstract This paper presents the basic concepts which comprise the Purdue Enterprise Reference Architecture along with a description of its development and use. This architecture provides the capability for modelling the human component as well as the Manufacturing or customer service component of anyenterprise in addition to the information and control system component. This latter component is the major focus of most reference architectures and models available today for Computer Integrated Manufacturing or complete enterprise study. This paper particularly points out those areas where this architecture differs from others available. In doing this it describes a new and unique method for defining the place of the human in the Computer Integrated plant or enterprise. It also develops the concept of customer service, which allowed the architecture, which was originally developed for Computer Integrated Manufacturing, to be extended to define the development and operation of any enterprise regardless of the industry or field of endeavor involved.
