Simul8

Simul8 is discrete event simulation software that helps organizations model processes, test operational changes, and compare outcomes before making changes in the real world. Operations, engineering, healthcare, manufacturing, supply chain, and service teams can use it to examine how people, equipment, materials, and work move through a system over time. Users build a visual process model, define its routing and business rules, and add factors such as demand variation, resource availability, shift patterns, and equipment downtime. They can then run scenarios to see how proposed changes affect throughput, waiting times, utilization, service levels, and costs. This supports decisions about staffing, schedules, capacity, layouts, inventory, and investments. Core capabilities include: - Visual process modeling for flows, resources, queues, timing, and routing. - Scenario testing to compare alternative operating conditions and proposed improvements. - Results and visualizations for measures such as throughput, utilization, and waiting times. - Data inputs from spreadsheets, with additional data workflows available through Minitab Connect. - Visual Logic scripting and developer tools for more customized simulation behavior. Simul8 can be used for a focused improvement project or for recurring planning as conditions change. Manufacturing teams might test a new production line or identify a bottleneck; healthcare teams might examine patient flow or staffing; logistics teams might compare warehouse layouts or distribution strategies. The model represents variability and constraints so teams can examine a range of possible results rather than relying on a single average. Models are created in Simul8’s desktop environment. Organizations using Minitab Connect can prepare and refresh operational inputs, while approved simulations can be published to Minitab Solution Center for stakeholders to explore scenarios through interactive dashboards. These connected workflows can help teams keep models current and share simulation results with decision makers.
