  • Analysis and Comparison of Fixed-Size Lot and Fixed-Time Lot Batch Production Systems

    Creator:
    Tiwari, Prashant
    Abstract:
    In high volume automated discrete item batch production systems, the batches or lots are typically fixed quantity (i.e., size), with setups incurred between the different production lots. Processing times for the fixed-size lots are relatively constant when the workstation is operating however, random workstation disruptions cause variability in the lot...

  • Rank and linear correlation differences in simulation and other applications

    Creator:
    Agahi, Maryam
    Abstract:
    Monte Carlo simulation is used to quantify and characterize uncertainty in a variety of applications such as financial/engineering economic analysis, and project management. The dependence or correlation between the random variables modeled can also be simulated to add more accuracy to simulations. However, there exists a difference between how correlation...

  • Work Overloads Approximation on a Moving Assembly Line Workstation using Markov Chain

    Creator:
    Khandke, Shardul
    Abstract:
    Moving mixed-model assembly lines are used by many companies to assemble multiple model types of a particular product. A moving assembly line consists of a material movement system that moves jobs at a constant velocity across a series of workstations. The variation in the work content of jobs at workstations...

  • Measuring Instrument Precision Estimation in Destructive Testing

    Creator:
    Sunil Raj, Sayooj
    Abstract:
    The variability introduced into measurements by a measuring instrument is referred to as measurement instrument precision. Experimental procedures and analysis methods exist when measurements are repeatable and can be repeated on the same item. However, when the measurements are destructive and repeated measurements are not possible, estimating measuring instrument precision...

  • Container fleet-sizing for part transportation and storage in the supply chain

    Creator:
    Park, SeJoon
    Abstract:
    This research addresses fleet-sizing for reusable containers that are used for protection, transportation, and storage of parts between a component plant and assembly plant. These reusable containers are often expensive and occupy a large amount of storage space when empty and full. Having a large container fleet comes with higher...

  • Selecting Probability Distributions for Use in Complex Discrete Event Simulation Models

    Creator:
    Moria, Eyad A.
    Abstract:
    In discrete event simulation, probability distributions are used as models of various unpredictable system components. The times between equipment failures and job processing times are examples of such random system components. The commonly recommended and taught practice for selecting a probability distribution to represent a random component is a multistep...

  • Utilizing smart manufacturing information in a job shop to support job selection and processing speed decisions

    Creator:
    Houck, Christopher
    Abstract:
    Creating schedules for the job shop manufacturing system is an extremely difficult task. Although researchers have devoted a lot of attention to generating optimal solutions, these solutions are static, thus they do not update as random events occur that disrupt the system. As smart manufacturing has grown, researchers have been...

  • A comparison of single runs versus multistart for simulated annealing and threshold accepting

    Creator:
    Crews, Matthew
    Abstract:
    Simulated Annealing and Threshold Accepting are two stochastic search algorithms that have been successfully used on a variety of complex and difficult problem sets. Due to their stochastic nature they are not guaranteed to produce the same result for each run. This means that these techniques actually produce a distribution...

  • Equipment replacement prioritization measures : simulation and testing for a vehicle fleet

    Creator:
    Kriett, Phillip Oliver
    Abstract:
    Oregon Department of Transportation (ODOT) Fleet Services manages a fleet that in 2008 included approximately 5,000 pieces of active equipment worth $340–$390 million. Every biennium, a fixed budget is available to replace a certain amount of this equipment. This research evaluated various measures for establishing equipment replacement priorities. A model...

  • Impact of asset usage preferences on parallel replacement decisions

    Creator:
    Wagner, Tristan John
    Abstract:
    Data from a state department of transportation fleet shows that the usage of a typical asset decreases as it ages. One possible explanation for decreasing asset usage with age is operator preference for using the newest available asset. In this research the long-term cost and replacement implications of such a...
