The PROVISION graphical user interface (GUI) provides a fully-interactive, Windows®-based environment with a full-featured drawing utility that incorporates point-and-click and drag-and-drop functionality for defining streams and unit operations-so drawing process flow diagrams (PFDs) is simple.

PROVISION incorporates many built-in Microsoft® standards, such as OLE Automation, enabling you to quickly transfer graphics and process data to other Windows applications. You can easily configure the environment to suit your preferences in many areas, such as units of measure, thermodynamics, and unit icon types. In addition, you can select interactive or batch calculation control and quickly review simulation results via on-demand reports, plots, and tables.

PROVISION employs a novel approach to problem specification. An interactive color-coded data entry and validation system guides you through simulation setup and execution. The result is a remarkably easy-to-learn and easy-to-use interface with visually enhanced program navigation.
