  • offshoring and the global Distribution of Work implications for task interdependence theory and practice
    Journal of International Business Studies, 2009
    Co-Authors: Kuldeep Kumar, Paul C Van Fenema, Mary Ann Von Glinow
    Abstract:

    A recent offshoring Research NetWork (ORN) global survey of offshoring shows that since 2004 management concerns about operational issues on achieving the benefits of offshoring have increased significantly. In this paper we examine inter-task interdependence, a key operational determinant of inter-site interaction and communications in offshoring. We analyze existing theories of interdependence to examine the extent to which they provide guidance for understanding the interaction and communication requirements between Work segments that are offshored and distributed across the globe. Using a series of mini-cases on globally distributed Work (GDW), we show how the traditional typology of interdependence developed in the 1960s and 1970s is no longer adequate for understanding and managing task interdependencies in GDW. We propose three concepts to address this problem: integration interdependence, “hand-offs”, and information “stickiness”. We then show how our revised typology of interdependence enables a better understanding of the interactions and communication requirements between sites. Using this revised theory we propose guidelines for Work design, and examine their implications for practical offshoring and Work-Distribution decisions. Implications for theory and practice for MNEs engaged in offshore relationships are discussed.

  • a genetic algorithm for robotic assembly line balancing
    European Journal of Operational Research, 2006
    Co-Authors: Gregory Levitin, Jacob Rubinovitz, Boris Shnits
    Abstract:

    Flexibility and automation in assembly lines can be achieved by the use of robots. The robotic assembly line balancing (RALB) problem is defined for robotic assembly line, where different robots may be assigned to the assembly tasks, and each robot needs different assembly times to perform a given task, because of its capabilities and specialization. The solution to the RALB problem includes an attempt for optimal assignment of robots to line stations and a balanced Distribution of Work between different stations. It aims at maximizing the production rate of the line. A genetic algorithm (GA) is used to find a solution to this problem. Two different procedures for adapting the GA to the RALB problem, by assigning robots with different capabilities to Workstations are introduced: a recursive assignment procedure and a consecutive assignment procedure. The results of the GA are improved by a local optimization (hill climbing) Work-piece exchange procedure. Tests conducted on a set of randomly generated problems, show that the Consecutive Assignment procedure achieves, in general, better solution quality (measured by average cycle time). Further tests are conducted to determine the best combination of parameters for the GA procedure. Comparison of the GA algorithm results with a truncated Branch and Bound algorithm for the RALB problem, demonstrates that the GA gives consistently better results.

  • a genetic algorithm for robotic assembly line balancing
    IFAC Proceedings Volumes, 2002
    Co-Authors: Gregory Levitin, Jacob Rubinovitz, Boris Shnits
    Abstract:

    Abstract Robotic assembly line balancing (RALB) is specific for robotic assembly, where different robots require different assembly times to perform the same task because of their specialization. The problem includes optimal assignment of robots to line stations and balanced Distribution of Work between different stations. It aims at maximizing the production rate of the line. This problem is solved by a genetic algorithm (GA). Different procedures for adapting the GA to the RALB problem are introduced, including a local optimization (hill climbing) Work-piece exchange procedure. The best combination of these procedures is reached by testing on a set of randomly generated problems.

  • high resolution kelvin probe microscopy in corrosion science scanning kelvin probe force microscopy skpfm versus classical scanning kelvin probe skp
    Electrochimica Acta, 2007
    Co-Authors: Michael Rohwerder, Florin Turcu
    Abstract:

    With the introduction of a Kelvin probe mode to atomic force microscopy, the so called scanning Kelvin probe force microscopy (SKPFM), the Kelvin probe technique finds application in a steadily increasing number of different fields, from corrosion science to microelectronics and biosciences. For many of these applications, high resolution is required as the relevant information lies in the sub-microscopic Distribution of Work functions or potentials, which explains the increasing interest in SKPFM. However, compared to the standard scanning Kelvin probe (SKP) technique SKPFM is prone to much more artefacts, which are often not taken into account in the interpretation of the results, as is also the case with the real physical nature of the measured data. A critical discussion of possible artefacts and on the interpretation of the data is presented in this paper, with the main focus on application in corrosion science.

  • effect of quantum collapse on the Distribution of Work in driven single molecules
    Physical Review Letters, 2004
    Co-Authors: Vladimir Chernyak, Shaul Mukamel
    Abstract:

    Two sources of quantum deviations from Jarzynski's celebrated classical relation between the free energy change and the Distribution of Work are analyzed using an exactly solvable harmonic model: Quantum dynamics retains the Gaussian profile of the Distribution and merely gives rise to analytic corrections in variant Planck's over 2pi, whereas quantum measurements (wave function collapse) induce extended power-law tails which fundamentally alter the Distribution. These results may be observed in quantum information processing and in experiments involving mechanically or optically driven single quantum objects.

  • quantum extension of the jarzynski relation analogy with stochastic dephasing
    Physical Review Letters, 2003
    Co-Authors: Shaul Mukamel
    Abstract:

    The relation between the Distribution of Work performed on a classical system by an external force switched on an arbitrary time scale and the corresponding equilibrium free energy difference is generalized to quantum systems. Using the adiabatic representation, we show that this relation holds for isolated systems as well as for systems coupled to a bath described by a master equation. A close formal analogy is established between the present "classical trajectory" picture over populations of adiabatic states and phase fluctuations (dephasing) of a quantum coherence in spectral line shapes, described by the stochastic Liouville equation.
