Simio

Simulation models are normally built by programmers; Simio's pitch is that processes and objects can be defined graphically, with no programming, in a fully object-oriented tool. Its engine is discrete event simulation, and the models it produces act as digital twins that let managers try what-if scenarios before they spend on new equipment or change a process.

Process digital twins that stay current

Simio describes a process digital twin as a virtual replica of an operation with a continuous, two-way link to the physical process. Because it takes in real-time information instead of relying on static history, the model can be used to find bottlenecks, reallocate resources and see what is likely to happen next. The company names advanced analytics, predictive capabilities and rapid side-by-side scenario comparison among its foundations, and talks about end-to-end visibility and connecting processes that depend on one another.

Risk-based planning and scheduling

The scheduling side adds risk into the production schedule. A model captures detailed constraints and the variation within a system, and the result is a feasible schedule. Simio calls its method patented, and its materials include a comparison of its approach with the scheduling module of a large ERP vendor.

From surgery suites to container depots

Its listed markets include defense and federal government work, food and restaurant service, and fast-moving consumer goods. Its case studies and papers reach into outpatient surgery scheduling, offshore supply vessels, airport gates, theme park rides, a crude-by-rail terminal, empty container stacking in a Chilean depot, distribution centers, mini-load storage systems for e-commerce in Japan and traffic signal timing. Other topics include Industry 4.0 scheduling, artificial intelligence and neural networks, and links to Matlab.

Academic use and the Solution Series

Simio promotes itself to universities as object-based teaching software and runs a Solution Series of tips and techniques, along with a grant program.
