Evaluating Capacity Options For The North American West Coast Container Ports., Jomon Aliyas Paul, Michael Maloni
Evaluating Capacity Options For The North American West Coast Container Ports., Jomon Aliyas Paul, Michael Maloni
Jomon Aliyas Paul
As global trade continues to recover from the recent economic recession, US container port congestion experienced in the last decade will likely re-emerge. Yet there is limited research that examines network-wide port capacity in support of solutions for minimizing such congestion. To address this gap, we simulate the US West Coast container port network, quantifying the costs and benefits of different options to better utilize current port capacity across the entire network. We specifically assess both efficiency improvement and operational coordination options on historical and future container volumes. The results demonstrate the strength of efficiency as a means to alleviate …
Dry Port Development In China: Motivations, Challenges, And Opportunities, Qincheng Zheng, Michael Maloni, Jomon Aliyas Paul
Dry Port Development In China: Motivations, Challenges, And Opportunities, Qincheng Zheng, Michael Maloni, Jomon Aliyas Paul

As coastal production costs in China rise, producers are moving inland to remain competitive with other Asian countries. As a result, Chinese sea ports are rapidly developing dry (i.e., inland) ports to compete for hinterland access. Yet the growing body of research examining dry ports has yet to analyze China. This article fills this gap by combining practitioner interviews, publicly available data, and industry and academic literature to provide an overview of dry ports in China. The article discusses the recent active development of dry ports in China and summarizes the existing dry port network. Motivations for further dry port …
A Process Flow Based Framework For Nurse Demand Estimation To Address Nurse Shortage., Jomon Paul, Leo Macdonald
A Process Flow Based Framework For Nurse Demand Estimation To Address Nurse Shortage., Jomon Paul, Leo Macdonald
Jomon Aliyas Paul
The nursing shortage in the United States poses a serious problem to hospitals, given that nurses provide an indispensable service within the healthcare system. This issue is expected to worsen, especially given the aging population of baby-boomers, which includes those that are part of the nurse workforce. This has resulted in a wide variety of problems, including patient safety issues, inability to detect complications, and potential patient mortality rate increases. Nurse shortage implications go beyond healthcare quality, extending to health economics as well. Inaccurate estimates of the nursing resources required to satisfy patient demand in a hospital environment could make …
Slow Steaming Impacts On Ocean Carriers And Shippers, Michael Maloni, Jomon Paul, David Gligor
Slow Steaming Impacts On Ocean Carriers And Shippers, Michael Maloni, Jomon Paul, David Gligor
Jomon Aliyas Paul
Ocean container carriers have implemented slow steaming (reduced vessel speeds) in recent years to improve fuel efficiency and lower greenhouse gas emissions. However, many shippers oppose the practice due to increased pipeline inventory associated with longer transit times. Given this conflict, this article seeks to quantify the costs and benefits of slow steaming relative to carriers and shippers. We simulate a high volume Asia-North America container trade lane to estimate slow steaming impacts under different vessel speeds, volumes and fuel prices. Under current conditions, the results justify slow steaming practices, revealing extra slow steaming as the most beneficial vessel speed …
Efficient Operating Room Redesign Through Process Improvement And Optimal Handling Of Scheduled And Emergent Surgeries, Jomon Paul, Arun Jotshi
Efficient Operating Room Redesign Through Process Improvement And Optimal Handling Of Scheduled And Emergent Surgeries, Jomon Paul, Arun Jotshi
Jomon Aliyas Paul
This article is focused on the benefits of reducing variability and the role of Operations Research techniques in efficient operating room (OR) redesign through process improvement and optimal management of scheduled and emergent surgeries at hospitals. Issues at a participant hospital are studied which are presented in this article where in the authors develop a three step OR redesign model to address them. The three step redesign was carried out as follows. Firstly, the process bottlenecks affecting OR performance were identified with the help of a Discrete Event Simulation Model (DES). Once the DES model focusing on the “As-Is” operations …
