[11] With the ongoing trend of Industry 4.0 pushing manufacturers toward automation and improved communication, FlexSim has been used to develop computer simulation models for these applications.

[13] The software has been used for nearly real-time production planning, which improves upon the Master Schedule approach (which can get out of date and miss on-site changes).

[14] In one study, FlexSim was integrated into a dynamic data-driven application system to automatically generate simulation models via the XML language.

[22] The environment has been used in various patient care improvement initiatives, including studies to understand different treatment options in Labor & Delivery,[23] deploying advanced practice nurses in treating non-urgent patients,[24] and demonstrating simulation-based design of a breast-screening facility as both a process improvement tool and as a management training tool.

Most standard objects contain an array of drop-down lists, properties windows, and triggers that allow the user to customize the logic required for an accurate model of the system.

FlexSim also includes a flowcharting tool to create the logic for a model using pre-built activity blocks.

Experienced users also have the option to specify and modify object parameters and behaviors using FlexScript and C++ programming languages.
