  • Evaluation of System Evolvability Based on Usable Excess
    Journal of Mechanical Design, 2016
    Co-Authors: Jeffrey D. Allen, Christopher A. Mattson, Scott Ferguson
    Abstract:

    Complex, large-scale engineered systems are an integral part of modern society. The cost of these systems is often high, while their ability to react to emergent requirements can be low. This paper proposes evolvability, based on usable excess, as a possible metric to promote system longevity. An equation for the usability of excess, previously defined only in terms of quantity, is improved to include the attributes of type, location, and form as well as quantity. A methodology for evaluating a system's evolvability is also presented. Using an Automated Assembly Line as an example, we show that system evolvability can be modeled as a function of usable excess.

  • Evaluation of System Reconfigurability Based on Usable Excess
    Volume 2B: 40th Design Automation Conference, 2014
    Co-Authors: Jeffrey D. Allen, Christopher A. Mattson, Jason D. Watson, Scott Ferguson
    Abstract:

    The challenge of designing complex engineered systems with long service lives can be daunting. As customer needs change over time, such systems must evolve to meet these needs. This paper presents a method for evaluating the reconfigurability of systems to meet future needs. Specifically we show that excess capability is a key factor in evaluating the reconfigurability of a system to a particular need, and that the overall system reconfigurability is a function of the system’s reconfigurability to all future needs combined. There are many examples of complex engineered systems; for example, aircraft, ships, communication systems, spacecraft and Automated Assembly Lines. These systems cost millions of dollars to design and millions to replicate. They often need to stay in service for a long time. However, this is often limited by an inability to adapt to meet future needs. Using an Automated Assembly Line as an example, we show that system reconfigurability can be modeled as a function of usable excess capability.Copyright © 2014 by ASME

  • hybrid Automated Line workstations interaction scenario for optical devices Assembly
    2016 18th Conference of Open Innovations Association and Seminar on Information Security and Protection of Information Technology (FRUCT-ISPIT), 2016
    Co-Authors: Alexey Kashevnik, Nikolay Teslya, Valery Arckhipov, Eugeny Yablochnikov, Kirill Kipriyanov
    Abstract:

    The paper propose a scenario for interaction of workstations in the hybrid Automated Assembly Line. Presented scenario is a part of optical devices Assembly process. For the interaction of workstations an ontology-based publish / subscribe self-organizing mechanism is used. For the scenario implementation, an appropriate 3D model has been developed with help of DELMIA modelling system. For modelling workstation interaction the services have been developed based on Smart-M3 information sharing platform that provides possibilities for information sharing and ontology-based publish / subscribe mechanism between different services in a common space.

  • Searching optimal resequencing and feature assignment on an Automated Assembly Line
    Journal of the Operational Research Society, 2009
    Co-Authors: A Lim
    Abstract:

    The resequencing and feature assignment problem (RFAP) appears among jobs in the Assembly Line, especially in the automotive industry. Each job in the Assembly Line must be assigned a feature from its feasible feature set. However, a changeover cost is incurred between two consecutive jobs with different features. To minimize the total changeover cost, the job sequence needs to be rearranged, but the rearrangement is restricted to the number of offLine buffers. The RFAP turns out to be \[Nscr]-hard in the strong sense. Based on a beam search heuristic to generate upper bounds of optimum solutions, we have proposed an iterative search scheme which can achieve optimum solutions in a reasonably short time, for cases sized as large as that in reality. Extensive experiments have shown very favourable results for our methods in terms of both the solution quality and the time efficiency.Department of Logistics and Maritime Studie

  • searching optimal resequencing and feature assignment on an Automated Assembly Line

    Abstract:

    In this paper, we have solved the resequencing and feature assignment problem (RFAP) by an iterative search scheme, which can obtain optimum solutions for instances sized as large as that in reality. The search scheme is based on a beam search heuristic, which outperform other heuristics in previous literature. The algorithms proposed can therefore be utilized to improve the vehicle manufacturing and to benchmark the optimum or near-optimum solutions for future research
