These flights are monitored and booked by airlines and the Transportation Security Authorities (TSA). A good forecast for international flights and travelers arriving and departing from the US may help to plan for immigration arrival proceedings, security screenings, monitoring, help to plan government budget spending on TSA processes as well as help to estimate income for the tourism industry among others. This study presents an analysis and forecast assessment of international flights and determines the best model for forecasting international flights. The study examines the seasonality of the data, finds the best model and finally makes a forecast prediction for the 2012 year. We then illustrate the model chosen for this forecast. In executing this study, we look at numerous modeling alternatives; time series regression, winter's exponential smoothing, decomposition method (automated and spread sheet), ARIMA, combination model with ARIMA and dynamic regression. The study concludes that dynamic regression is the best forecasting model with its unique handling capabilities of interventions and seasonality, and presents recommendations.

At the University of Tennessee, Knoxville, Industrial and Systems Engineering students have an opportunity, in the Student Projects with Industry (SPI) program within the Center for Productivity Innovation, to develop their research ideas in conjunction with industry. The success of the SPI program is assessed by evaluating the impact of the SPI program on the preparation of the students, the academic welfare of the department, and the program’s economic and social impact on the community. The SPI program provides students with simulated work experiences that enhance their leadership attributes, developing students’ critical thinking capabilities, and improving their technical, organizational, and social skills. That these skills enhance students’ success both in the university and in their careers is evident in measurable results, including higher student graduation rates, an increased number of publications, and a wider sponsor network for potential funding. The impact can further be measured by the millions of dollars affecting the local economy, in addition to the intangible social benefits gained.

Urban use of EVs rather than conventional vehicles shifts transportation's air pollutant emissions from urban areas (tailpipes) to predominantly rural areas (power plants), changing the geographic distribution of health impacts. We model PM2.5-related health impacts attributable to urban EV use for 34 major cities. Our investigation focuses on environmental justice (EJ) by comparing pollutant inhalation versus income among impacted counties. We find that EVs could increase environmental injustice in China: most (~77%, range: 41-96%) emission inhalation attributable to urban EVs use is distributed to predominately rural communities whose incomes are on average lower than the cities where EVs are used. Results vary dramatically across cities depending on urban income and geography. Discriminant analysis reveals that counties with low income and hig...

Managing risk in the supply chain has never been as challenging as it is today. This paper develops a comprehensive quantitative risk evaluation and mitigation model in global supply chains from several disciplines -logistics, supply chain management, operation management, economics and international business. A case study is provided based on a real company whose products are manufactured in China and sold in U.S. Firstly, four main risks including supply risk, operational risk, demand risk and financial risk, are identified and modeled as probabilistic distributions of the outcome of adverse events associated with the components throughout the supply chain. These risks are further incorporated into a simulation model, and quantitatively evaluated using @Risk 5.0. Furthermore, some risk mitigation strategies such as hedging and speculation are implemented and integrated with the simulation model for further investigation.

Flight simulations were conducted with the UTSI's Aviation Systems research flight simulator to validate the display and to evaluate its utility for flying along constant specific excess power (PS) contours and for directly obtaining PS contours from level acceleration flight test. This study considers the energy state of the aircraft from the point of view of the relation that exists between specific excess power, PS, and the forces in flight. The approach yields as one result a cubic function for the PS of the aircraft. We then directly solve for velocity, V, as the control parameter for a given PS as a function of altitude, H. Using LabView software, this technique is used to build a real-time energy management display which provides guidance and real-time information on the aircraft's energy state. Flight simulation results proved the display to be successful in obtaining direct PS contours from level acceleration flight tests and in providing guidance for flights along constant PS contours at low airspeeds, although it was difficult to keep the PS constant.

Recent industrial engineering graduates face difficulties in structuring their acquired knowledge from an open-ended problem solving perspective. Leadership at Boeing is determined by the ability to define knowledge, model and mentor/teach others that knowledge. By this definition, industrial engineers fall short on their ability to teach others their problem solving process. This paper first provides a framework for a set of attributes, defined to establish the core elements of what industrial engineers must learn, practice and develop for sustainable solutions, to later introduce the D.R.I.V.E.S. model as a structured methodology for continuous improvement, using different industrial engineering tools to narrow down open-ended problems into a sequence of steps to propose the right set of solutions and ensure sustainable improvement implementations.

This paper focuses on modeling the effects of different degrees of variation (high, medium and low) at different location in a manufacturing process. A simulation study applies design of experiments to determine the influence of different types of variations on the performance measures. The process performance measures considered are throughput, work in process, value added time, wait time, and total output of the process. This study identifies the location and level of improvement in a process to increase the overall gain in performance measures and reliability of the manufacturing process.

This paper presents a new idea of treating the time spent in developing a simulation model as lead-time. The concept of simulation lead-time is derived from lean principles. This paper proposes a framework composed of different steps, techniques, and mechanisms to reduce this simulation lead-time.
