Description
The efficient refurbishment of rotable parts on an aircraft proves to be a main concern for airline carriers today. Airlines must be able to seamlessly rotate parts into and out of the system for maintenance in accordance with FAA requirements while leaving daily operations uninterrupted. In this paper, we develop an airline maintenance scheduling model that constructs an optimal schedule for part maintenance over a given time horizon using deterministic forecasting techniques. The model generates a schedule that minimizes the total cost of a maintenance schedule solution while maximizing the utility of all parts in the system. The model is then tested against actual network data of three part types crucial to airline operations and used to investigate the current data collection processes of US Airways maintenance lead time metrics. Manual sensitivity analysis is performed to generate the marginal value of each parameter and potential model extensions are highlighted as a result of these conclusions.

Description
In recent years, Operations Research (OR) has had a signicant impact on improving the performance of hospital Emergency Departments (EDs). This includes improving a wide range of processes involving patient ow from the initial call to the ED through disposition, discharge home, or admission to the hospital. We mainly seek to illustrate the benet of OR in EDs, and provide an overview of research performed in this vein to assist both researchers and practitioners. We also elaborate on possibilities for future researchers by shedding light on some less studied aspects that can have valuable impacts on practice.

Description
The deductive logic and leadership techniques presented in Dr. Dean Kashiwagi's Information Measurement Theory (IMT) and the Kashiwagi Solution Model (KSM) provide the tools to implement positive change within one's life and environment. By altering the way that I perceive the world, I have made progress in self-improvement through action. This project utilizes self-evaluation as a method to learn from dominant information and experience. In establishing that natural laws govern the world, there is no randomness; events and decisions are all cause-and-effect. When seen through this lens, life becomes simpler and manageable. Through my own implementation of IMT and KSM, I live a more productive lifestyle and feel that I have a meaningful plan for my future.
