CORE DEFINITION

A graphical mathematical modeling tool used to describe and analyze concurrent, asynchronous, and distributed systems, composed of places (states), transitions (events), and directed arcs.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Visual analysis of concurrent systems. Transform complex concurrent behavior into analyzable graphical models, facilitating the discovery of deadlocks, conflicts, and other issues.

anchor

Anchor fast decisions

Use graphical mathematics to describe concurrent systems: places (states/conditions) are represented by circles, transitions (events) by boxes, and tokens flow between places to represent resources/states. A transition fires when its input places have tokens; firing consumes and produces output tokens. Formal analysis of deadlocks, conflicts, and reachability is possible.
