    Many aspects of manufacturing systems can be analyzed using simulation to model the system's behavior. The Research Queueing Package (RESQ) is a tool developed to construct and solve models of systems with jobs contending for service from many resources. The capabilities of RESQ are described in order to understand the model elements which are available for representing manufacturing systems. Then... View full abstract»

    The objective of the Integrated Manufacturing Modeling System (IMMS) project was to build a generic software package for manufacturing modeling. The package allows interactive model building, testing, and experimentation. IMMS integrates the fundamental components of modeling, namely system description, data acquisition and management, graphic input and output, and performance simulation. The fund...

  • An algorithm for carrier routing in a flexible material-handling system

    Publication Year: 1985, Page(s):356 - 362
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (562 KB)

    Flexible material-handling systems for manufacturing have the capability of moving articles or carriers between process stations in different sequences. The traditional method for controlling the routing of carriers is to determine, in advance, all of the useful paths within the system, and store the information in a central computer until needed. This article describes a routing algorithm that de... View full abstract»

  • Precise manipulation with endpoint sensing

    This paper describes recent work on manipulation strategies that rely on “coarse-fine” robot hardware and direct sensing of part-workpiece relationships. The experiments reported use an extremely precise, high-bandwidth planar “wrist” and an industrial vision system to perform accurate alignment of small parts. The system architecture, experimental hardware, and program... View full abstract»

  • On the analysis and design of CUSUM-Shewhart control schemes

    Publication Year: 1985, Page(s):377 - 391

    In recent years cumulative sum (CUSUM) control charts have become increasingly popular as an alternative to Shewhart's control charts. These charts use sequentially accumulated information in order to detect out-of-control conditions. They are philosophically related to procedures of sequential hypothesis testing (the relation being similar to that existing between Shewhart's charts and classical ... View full abstract»

  • Short-term production scheduling of an automated manufacturing facility

    Publication Year: 1985, Page(s):392 - 400
    Cited by:  Papers (57)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (717 KB)

    We describe a new implementation of the Kimemia-Gershwin hierarchical policy for the real-time scheduling of flexible manufacturing systems. Major improvements result at all three levels of the policy. The algorithm simplification, resulting in substantial reductions of off-line and on-line computation time, is reported, as is the improvement in performance through the elimination of chattering. S... View full abstract»

  • Scheduling algorithms for flexible flow lines

    Publication Year: 1985, Page(s):401 - 412
    Cited by:  Papers (10)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (920 KB)

    This paper discusses scheduling algorithms for a certain kind of manufacturing environment, called the “flexible flow line.” Two scheduling problems are considered. “Loading” decides when each part should be loaded into the system. “Mix allocation” selects the daily part mix. The goals are to maximize throughput and reduce WIP. New heuristic algorithms spe... View full abstract»

  • A prototype manufacturing knowledge base in Syllog

    Publication Year: 1985, Page(s):413 - 421
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (759 KB)

    This paper describes a prototype knowledge base for manufacturing planning, which we have built using a knowledge system shell called Syllog. We describe a Tester Capacity Planning and Yield Analysis task, knowledge needed for a part of the task, and the use of the knowledge in the Syllog system. We report that the sometimes difficult process of knowledge acquisition turned out, in this case, to b... View full abstract»

  • Large-scale scientific application programs in chemistry and physics on an experimental parallel computer system

    Publication Year: 1985, Page(s):422 - 432
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (959 KB)

    We present and discuss an experimental distributed system consisting of two IBM 4341s, an IBM 4381, and ten FPS-164 attached processors, configured to allow parallel execution of a single large-scale calculation on multiple processors. A number of our application programs have been converted to run on this system, and the strategy for this conversion is outlined in sufficient detail to facilitate ... View full abstract»
