Harmony Search For Structural Design, Zong Woo Geem, Kang Seok Lee, Chung-Li Tseng

Engineering Management and Systems Engineering Faculty Research & Creative Works

Various algorithms have been developed and applied to structural optimization, in which cross-sectional areas of structure members are assumed to be continuous. in most cases of practical structure designs, however, decision variables (cross-sectional areas) are discrete. This paper proposes a combinatorial optimization model for structural design using a new nature-inspired algorithm, harmony search (HS). HS is also compared to genetic algorithms through a standard truss example. Numerical results reveal that the proposed HS is a powerful search algorithm for combinatorial structure optimization.

Conceptual Simulation Modeling For Regional Distribution Center Systems, Kitti Setavoraphan

All-Inclusive List of Electronic Theses and Dissertations

This study focuses on the simulation modeling of warehousing operations commonly seen at general merchandize distribution centers. The key operational processes and modeling requirements related were identified and analyzed through a pattern and knowledge-based approach to capture the structural and behavioral characteristics of general distribution centers to support simulation study for performance evaluation and process improvement. Robust representations and patterns were developed to represent the elements and logic of the simulation models for these processes to facilitate efficient and effective construction of models. The issues of conceptual modeling such as synthesis, abstraction, decomposition, and specialization were addressed.

Guidelines To Select A Computerized Maintenance Management System, Dattaraj Kamalapurkar

Masters Theses

In today's highly competitive global economy, maintenance personnel are presented with more difficult challenges than at any previous point in time. In order to meet these challenges, many maintenance managers tend to rely . on Computerized Maintenance Management System (CMMS). When properly selected and implemented, CMMS is one of the most powerful cost reduction tools in any organization. However in reality, many CMMS implementations fail rather than achieve success. While there are many contributing factors, one major factor that greatly impacts successful implementation is selecting the right CMMS system. With more than 200 CMMS systems to choose from, selecting the …

Simulating Discriminatory Profiling, Oscar Neal

Masters Theses

There is a concern that racial profiling is being used to invoke searches and stops in spite of its violation of the fourth amendment. Simulation methods are used to study the correlation test of stops, searches and citations with race, age, and gender. The design uses sensitivity analysis of inputs to determine their relationship to outputs statistics of a police department's citations and stops. Experimental results are than used to verify and predict departmental bias. A simulation program written in Visual Basic is used as a tool to explore simulation techniques. A formulation of simulation uses in studying discriminatory profiling …

Distributed Simulation Modeling For Manufacturing Systems Design Using Xml, Rawinkhan Srinon, Sreeram Ramakrishnan

Engineering Management and Systems Engineering Faculty Research & Creative Works

Discrete event simulations have been used to model manufacturing systems. Various decomposition methods such as distributed simulations have been employed for this modeling. in the context of distributed simulations, each federate must be able to share the embedded logic with the other federates, irrespective of the software used to design and build such systems. This paper provides an extensible Markup Language (XML)-Based representation for distributed models that can be shared across the federation of simulations. Specifically, the paper outlines three different model components that forms the basis of a design framework for distributed simulation models - object model (for simulation …

Statistics-Based Approaches To Stochastic Optimal Control Problems, Aihong Wen

Industrial, Manufacturing, and Systems Engineering Dissertations - Archive

This dissertation develops practical approaches to stochastic optimal control problems in the absence of linear system transition functions, quadratic cost functions, and/or Gaussian random disturbances. In such type of problems, an analytical solution is impossible and numerical synthesis techniques have to be applied. The ''classic'' algorithms existing in the literature suffer from the problem of the''curse of dimensionality,'' an exponential increase of computation time and memory requirements as the dimension of the problem grows. The statistics-based numerical approaches are presented as the main tools for mitigating the ``curse of dimensionality'' phenomenon. Two approaches are explored: (A) stochastic dynamic programming (SDP), …

Leveraging Itil To Govern Aoc Information Technology, Robert V. Weaver Iii

Theses and Dissertations

The Air Operations Center (AOC) is a complex system of systems that is resistant to traditional engineering controls and management strategies. The US Air Force (USAF) seeks to transform its antiquated AOC Information Technology (IT) management function into an agile enterprise capable of leveraging cutting-edge technology by aligning the AOC's infrastructure with its organizational strategies and vision. The USAF calls this effort a transformation. Private industry calls it IT Governance. To achieve AOC IT Governance, the USAF must stop managing infrastructure components and start managing IT services. IT Service Management abstracts business processes from the technology supporting them by creating …

A Generic Object-Oriented Tabu Search Framework, Hoong Chuin Lau, Xiaomin Jia, Wee Chong Wan

Research Collection School Of Computing and Information Systems

Presently, most tabu search designers devise their applications without considering the potential of design and code reuse, which consequently prolong the development of subsequent applications. In this paper, we propose a software solution known as Tabu Search Framework (TSF), which is a generic C++ software framework for tabu search implementation. The framework excels in code recycling through the use of a well- designed set of generic abstract classes that clearly define their collaborative roles in the algorithm. Additionally, the framework incorporates a centralized process and control mechanism that enhances the search with intelligence. This results in a generic framework that …

Effect Of Sound Cue Frequency Filters On Front/Back Localization Performance For Three-Dimensional Verbal And Non-Verbal Warnings, Angelica A. Hernandez

Master's Theses - Daytona Beach

In aviation, as technology becomes more advanced and more demands are placed on the human operator, warnings have become an important part of display design. Although warnings have made a significant contribution to safety, problems still plague their design. Recent technological advances have been able to give sounds and warnings a three-dimensional quality (3D). This technology enables a person to perceive sound from any direction around the listener without having the sound physically come from that direction. Three-dimensional sounds have been shown to improve target acquisition and collision avoidance in flight (Oving & Bronkhorst, 1999), and may have other future …

Support For A Delivery Train Based Material Handling Mechanism, Sai P. Boyedapu

Electrical & Computer Engineering Theses & Dissertations

Modeling a delivery train system is more challenging than traditional forklift systems as the delivery train model consists of a tugger, cart and a controller that combine to deliver materials within a manufacturing plant. Also, the decision logic for selection of carts and tuggers, joining of loads to particular delivery trains is more complicated than forklift systems. Simulation software such as Arena, Automod and Flexsim do not provide direct support for modeling delivery train systems.

In this thesis, an object-oriented, platform and language independent model of a delivery train was designed. The model was then implemented as an extension to …
