Screening of passengers at the airport security check point is one of the most critical measures to ensure our nation’s aviation security and safety. In this study, we investigate the operational efficiency and inspection effectiveness of passenger screening, including the magnetometer (MAG), X-Ray machines, manual wand search, trace of explosive residuals, and private screening at an airport. Passenger volumes by the day of the week and times of the day, along with the corresponding staffing levels of the screening personnel are modeled. Performance of the security system with respect to passengers making the flights on time is evaluated for various …

Patient throughput has become one of the most common measures of hospital performance in terms of patient satisfaction and operational efficiency. Throughout the country hospital emergency departments, which generally supply almost 50% of the inpatient population, face increased pressure on improving patient flow. Similarly performance of ORs, the largest revenue grosser for the hospital significantly affects the patient satisfaction considerably. In addition to employing a DMAIC - Lean Six Sigma approach to resolve these problems, In simulation has been used as an excellent tool to implement the Analyze and Improve phases of the six-sigma methodology. We used simulation, integrated with …

Rapid estimates of hospital capacity after an event that may cause a disaster can assist disaster-relief efforts. Due to the dynamics of hospitals, following such an event, it is necessary to accurately model the behavior of the system. A transient modeling approach using simulation and exponential functions is presented, along with its applications in an earthquake situation. The parameters of the exponential model are regressed using outputs from designed simulation experiments. The developed model is capable of representing transient, patient waiting times during a disaster. Most importantly, the modeling approach allows real-time capacity estimation of hospitals of various sizes and …
