Simulation methods have been widely applied to a variety of OR problems and domains, such as manufacturing, logistics, healthcare, finance, and education. In manufacturing, simulation can be used to optimize the layout, capacity, scheduling, inventory, and quality of a production system. It can also be used to assess the impact of disruptions, changes, and improvements. In logistics, simulation is used to design and manage the transportation, distribution, and delivery of goods and services. It can also help evaluate the trade-offs between cost, time, and service level. Simulation is also used in healthcare to plan and allocate resources, staff, and facilities of a healthcare system. It can also analyze the effects of policies, interventions, and innovations. In finance, simulation is used to forecast and manage risk, return and performance of financial assets and portfolios. It can also test and optimize the strategies and decisions of investors and traders. Lastly in education simulation is applied to create interactive learning experiences as well as measure learning outcomes and feedback of learners and educators.
