This diagram represents a simple resource management system focused on the flow of a singular type of resource, designated by its "Black" color, through a production, storage, and consumption cycle. A Source node generates an infinite amount of the resource, which is then directed into a Pool node where the resource is temporarily stored. From this Pool, the resource is subsequently channeled towards a Drain node, signifying its consumption and removal from the system. The connections between these nodes are designed to facilitate a constant flow rate of "1", indicating that resources are moved from the Source to the Pool, and from the Pool to the Drain at a steady pace during each step of the diagram's operation. This setup encapsulates a closed-loop system where resources are produced, held, and then expended, showcasing a basic but fundamental economic model that could simulate a wide range of scenarios from consumable item flow in a video game to resource allocation in a logistical simulation.
