Case Studies

  • CSX Solves Railroad Operation Challenges with and without AnyLogic Rail Library
    CSX is a US railroad company that operates about 21,000 route miles (34,000 km). AnyLogic allows the railroad industry users to simulate line-of-road, terminal, and yard problems. The following three projects, completed by CSX in 2014, covered a variety of tasks that were solved using AnyLogic software.
  • Customer-Centric Transportation Network Modelling
    The public transportation company employed PwC Australia to develop a solution that could provide a customer-centric view of their railway infrastructure and help the company understand the current incident effects on rail network operations and how to improve the situation. PwC consultants decided to build a model of the transportation network that would simulate train movements, incidents, and customers at stations and in trains.
  • Disaster Response Applications Using Agent-Based Modeling
    In an effort to find practical operational solutions for response to an unexpected crisis or natural disaster, Battelle, world’s largest, non-profit, independent R&D organization, needed to test the effectiveness of a 48 hour shelter-in-place order for an Improvised Nuclear Device scenario. The goal was to reduce radiation dosages received during an uncoordinated mass evacuation, by comparing immediate evacuation and shelter-in-place order.
  • Emergency Evacuation Planning: Minimizing Gridlock and Improving Public Safety
    A typical rush hour impedes the mobility of individual vehicles and significantly slows the overall flow of traffic. This phenomenon is compounded by events of mass mobilization, such as during an evacuation due to a hurricane or other event. When this occurs, traffic can reach a state of gridlock. ITS researchers sought to understand how public safety could be improved during such events by incorporating communication among a percentage of the vehicle population.
  • Evaluating Healthcare Policies to Reduce Rates of Cesarean Delivery
    The challenge of reducing the cesarean delivery rate has been recognized by numerous researchers for years. For the first time, in research conducted for the Washington State, Alan Mills, FSA MAAA ND, a research actuary, and his colleagues reproduced this part of the United States healthcare system in a simulation model to allow the stakeholders, including health agencies, insurers, clinicians, and legislators, to test their assumptions on the model to find the right solutions.
  • Evaluating Hospital Inpatient Care Capacity
    Stockholm County, Sweden was in the process of building a new, highly specialized hospital. The Health Administration of the county questioned whether they would get an acceptable level of care production with the current investments and reasoning concerning various operational and strategic issues. To find the answers, they used simulation modeling in AnyLogic.
  • Evaluating Introduction of Warehouse Automation Systems
    Symbotic is a warehouse automation solutions provider. Its systems are based on mobile robots that can travel freely throughout a dense storage structure, accessing products in all locations and handling them at a very high throughput rate. The company needed a tool to help their customers learn the impact of warehouse reorganization and compare capital investments against expected operational savings before the actual introduction of automation systems.
  • Handling Total Care Need for Dialysis Patients
    The County of Stockholm (Sweden), like any country or region, experiences a continuous need to handle the healthcare necessities of various patient groups. Each group can be seen as a subpopulation, with its own distinctive traits, characteristics, and challenges. The discussed simulation project focused on the dialysis patients, a group who needs to visit caregiving facilities frequently.
  • Improving Plane Maintenance Process with AnyLogic Agent-Based Modeling
    The military aircraft maintenance turnaround process (the in-between time when the aircraft touches down, is refueled, rearmed, and inspected, in order to be released) is complex and, being fairly time-consuming, includes multiple interactions and parallel workflows. Engineers from Lockheed Martin, one of the largest companies in the aerospace, defense, security, and technologies industry, used AnyLogic simulation modeling to improve decision making in the entire military airplane turnaround process and evaluate the impact of process changes on turnaround time.
  • Major US Airline Decides NOT to Charge Additional Fees
    A major US airline wanted to explore several options to generate new profits through ancillary products or changes to existing policies. Although the revenue generation through charging additional fees was apparent in the short term, prior to implementing a policy change, the airline opted to evaluate the long term perceived impact on brand equity, market share and customer loyalty.
