Flow Network Class

Description:A network that flows a Commodity

See also Flow Network Property Reference for a detailed list of properties for this class of object.

Related Classes: Commodity, Process, Facility, Market, Flow Node, Flow Path, Flow Storage.

Overview

A Flow Network flows a single Commodity through a collection of Flow Node objects linked by Flow Path objects, with optional storage in Flow Storage objects.

Example

Figure 1 shows a three node network in which a Facility "Plant" produces a Commodity "Water" that flows on the network from the "Source" node to the "Sink" node where it is sold in a Market. The Flow Path from "Source" to "Sink" is limited in capacity but the market can be reach via the "Bypass" node along a different set of Flow Path objects but there is a cost associated with flows through that node.

Table 1 lists the objects for this example, Table 2 the memberships and Table 3 the properties.
