Logistics Planning for a Large Mineral Resources Company


Logistics Planning for a Large Mineral Resources Company

Companies in the mining and energy sectors face many of the same supply chain challenges of other industries. Transportation services, warehouse management, and global services are intertwined in moving equipment and supplies to the work site and shipping cargo to customers. These challenges make it difficult to predict the likely system impact of local decisions or how changes in one part of the system cause undesirable effects to other divisions. In 2013, the largest mineral resources company contracted Goldratt Research Labs and Amalgama to develop a simulation tool that would allow for better decision-making on a day-to-day and long term basis. The project requirements included...]

Optimal Aircraft Boarding Strategy


Optimal Aircraft Boarding Strategy

To increase profit, airlines seek to minimize turnaround time. Turnaround time is attributed to multiple factors, disembarkation, baggage unloading, refueling, cargo unloading, aircraft maintenance, cargo and baggage loading and passenger boarding. A group in the Science and Engineering Faculty at Queensland University of Technology in Brisbane, Australia completed a project using AnyLogic software to investigate the turnaround time for aircraft passenger boarding using AnyLogic simulation software. The recently published paper studied seven common boarding strategies and two new suggested strategies to find the optimal boarding methods for a Boeing 777 and Airbus 380. They considered behavior of groups traveling together, and individuals storing luggage as part of the simulation model.

Modeling and Optimization of Unconventional Oil Production


Modeling and Optimization of Unconventional Oil Production

Canada's oil reserves are third only to Venezuela and Saudi Arabia, and over 95% of these reserves are in the oil sands deposits in the province of Alberta. Oil sands are a deposit of loose sand or partially consolidated sandstone containing petroleum or other hydrocarbons which require in situ methods for production. The in situ method is more costly than the mining method, but it's much less damaging to the environment, requiring only a few hundred meters of land and a nearby water source to operate. It's estimated by the Alberta government that 70-80% of oil in the oil sands is buried too deep for open pit mining; therefore, in situ methods will likely be the future of extracting oil from oil sands. The most common form of in situ is called Steam Assisted Gravity Drainage (SAGD). With the SAGD technique, a pair of horizontal wells, situated 4 to 6 meters above the other, is drilled from a central well pad. In a plant nearby, water is transformed into steam which then travels through above-ground pipelines to the wells and enters the ground via a steam injection (top) well.

Disaster Management Aid Simulation


Disaster Management Aid Simulation

In the wake of a disaster, natural or otherwise, a power outage can cause residual damage and hardships. To reduce the length of power outages, utility companies often have mutual aid agreements in place. Mutual aid agreements provide a mechanism to acquire emergency assistance quickly in the form of materials, equipment, personnel and other relevant services. There are many factors that drive the deployment of assistance during a disaster (i.e. distance, urgency, cost, extent of damage, etc.) To help utility companies make better, faster decisions, York University applied simulation modeling with AnyLogic software to manage the process of mutual assistance. Learn more via the case study or recorded presentations from AnyLogic Conference 2015.

Outpatient Appointment Scheduling


Outpatient Appointment Scheduling

Indiana University Health Arnett (IUHA) is an integrated healthcare system which consists of a full service acute care hospital and a multispecialty clinic with approximately 200 providers at numerous locations. In the past, provider schedules were driven by individual preference which led to increased variation in scheduling rules that failed to meet employer or patient expectations. To better serve patients and maintain provider approval, IUHA sought to develop a scheduling methodology that provides same day access for a designated patient population while allowing acceptable access to the remaining patient population.

Beyond Market Mix Models


Beyond Market Mix Models

Traditional Marketing Mix models attempt to explore the tradeoffs amongst different marketing channels and the spends associated with them. The weaknesses of these models are, generally, their static nature and the restrictive assumptions required to apply their results. For these reasons, an American pharmaceutical company, one of the largest in the world, engaged with Sterling Simulation to explore the benefits of agent-based modeling, prior to launching a new product. The use-case was presented by Scott Hebert, Vice President of Sterling Simulation at the AnyLogic Conference 2015.
