  • Multivariate control charts for nonconformities

    Creator:
    Chattinnawat, Wichai
    Abstract:
    When the nonconformities are independent, a multivariate control chart for nonconformities called a demerit control chart using a distribution approximation technique called an Edgeworth Expansion, is proposed. For a demerit control chart, an exact control limit can be obtained in special cases, but not in general. A proposed demerit control...

  • Performance evaluation of heterogeneous wireless local area network systems

    Creator:
    Paotrakool, Kittiporn
    Abstract:
    The market for Wireless Local Area Networks (WLANs) has experienced tremendous growth over the last few years and this trend is expected to continue in the future. This growth is due to the fact that wireless LANs provide several benefits including mobility, efficiency, and accuracy. In addition, the cost of...

  • Multi-mode resource-constrained project scheduling problem with resource vacations and task splitting

    Creator:
    Buddhakulsomsiri, Jirachai
    Abstract:
    The research presented in this dissertation addresses the Multi-Mode Resource-Constrained Project Scheduling Problem (MMRCPSP) in the presence of resource unavailability. This research is motivated by the scheduling of engineering design tasks in automotive product development to minimize the project completion time, but addresses a general scheduling situation that is applicable...

  • Application of buckling behavior to evaluate and control shape variation in high-temperature microlamination

    Creator:
    Wattanutchariya, Wassanai
    Abstract:
    The miniaturization of energy, chemical and biological systems for distributed and portable applications, known as process intensification, is realized by the enhancement in heat and mass transfer performance within high surface-to-volume ratio microchannels. Fabrication of devices for process intensification is achieved in part by microlamination techniques. These techniques consist of...
