  • A Framework for a Fuzzy Sustainable Maintenance Strategy Selection Problem -- restricted access to full text 

    Nezami, Farnaz Ghazi (Wichita State University. Graduate School, 2011-05-04)
    Maintenance cost constitutes 15-60% of the total production cost. Choosing the right maintenance strategy might provide significant savings in lost production, additional power consumption and lifecycle costs. An optimum ...
  • A framework to minimise total energy consumption and total tardiness on a single machine 

    Mouzon, Gilles C.; Yildirim, Mehmet Bayram (Taylor & Francis, 2008)
    A great amount of energy is wasted in industry by machines that remain idle due to underutilisation. A way to avoid wasting energy and thus reducing the carbon print of an industrial plant is to consider minimisation ...
  • A framework to minimize total energy consumption and total tardiness on a single machine 

    Mouzon, Gilles C.; Yildirim, Mehmet Bayram (Wichita State University. Graduate School., 2008-04-25)
    A great amount of energy is wasted in industry by machines which stay idle due to underutilization. A way to avoid consuming the wasted energy is to incorporate energy consumption into consideration while making the ...
  • A fully Bayesian approach for sample size determination 

    Safaie, Nasser (Wichita State University. Graduate School, 2010-04-23)
    The sample size determination plays a significant role in design and analysis of many engineering problems plus data sampling projects. There is a number of sampling techniques including both classical as well as Bayesian ...
  • A fuzzy multi objective model for a green generation expansion problem 

    Meza, Jose L. Ceciliano; Nezami, Farnaz Ghazi (Wichita State University. Graduate School, 2010-04-23)
    In this paper, a comprehensive fuzzy multi-objective model is presented for generation expansion planning problem considering uncertainty in objective functions and demand constraint. The purpose of the model is determining ...

  • Gender influences on spine loads during complex lifting 

    Marras, William S.; Davis, Kermit; Jorgensen, Michael J. (Elsevier, 2003-03)
    Background context: Previous research has documented differences in spine loading between genders when the imposed load is normalized relative to the size of the person. However, under realistic work conditions the magnitude ...
  • A generic model-free approach for lithium-ion battery health management 

    Bai, Guangxing; Wang, Pingfeng; Hu, Chao; Pecht, Michael (Elsevier Ltd., 2014-12-15)
    Accurate estimation of the state-of-charge (SoC) and state-of-health (SoH) for an operating battery system, as a critical task for battery health management, greatly depends on the validity and generalizability of battery ...
  • A generic probabilistic framework for structural health prognostics and uncertainty management 

    Wang, Pingfeng; Youn, Byeng D.; Hu, Chao (Elsevier, 2012-04)
    Structural health prognostics can be broadly applied to various engineered artifacts in an engineered system. However, techniques and methodologies for health prognostics become application-specific. This study thus aims ...
  • A Generic Reliability and Risk Centered Maintenance Framework for Wind Turbines 

    Jagannath, Dwarakanath (Wichita State University. Graduate School, 2011-05-04)
