Example of a flow diagram of a nuclear submarine propulsion system.

Flow diagram is a collective term for a diagram representing a flow or set of dynamic relationships in a system. The term flow diagram is also used as a synonym for flowchart,^[1] and sometimes as a counterpart of the flowchart.^[2]

Flow diagrams are used to structure and order a complex system, or to reveal the underlying structure of the elements and their interaction.^[3]

Overview

The term flow diagram is used in theory and practice in different meanings. Most commonly the flow chart and flow diagram are used in an interchangeable way in the meaning of a representation of a process. For example the Information Graphics: A Comprehensive Illustrated Reference by Harris (1999) gives two separate definitions:

Flow chart or flow diagram... is a diagram that visually displays interrelated information such as events, steps in a process, functions, etc., in an organized fashion, such as sequentially or chronologically.^[4]

Flow diagram [is] a graphic representation of the physical route or flow of people, materials, paperworks, vehicles, or communication associated with a process, procedure plan, or investigation.^[2]

In the second definition the meaning is limited to the representation of the physical route or flow. An example of such a diagram is the illustration of the flows in a nuclear submarine propulsion system, which shows different streams back and forth in the system. The representation of such a system can be supplemented by one or more flowcharts, which show the sequence of one of the flows in one direction, or any of the control flows to manage the system.

The physical movement of objects from one location to another can also be visualized in a mix of maps and flowchart or sankey diagram, which are called flow maps. Flow maps can indicate on a map, what flows, moves or migrates, in which direction, and in which quantities etc.^[5]

Specific types of flow diagrams

In theory and practice specific types of diagrams are also called a type of flow diagrams, such as:

Alluvial diagram, highlights and summarizes the significant structural changes in networks
Circular flow of income
Control flow diagram, a diagram to describe the control flow of a business process, process or program
Cumulative flow diagram, a tool used in queuing theory.
Functional flow block diagram, in systems engineering
Data flow diagram, a graphical representation of the flow of data through an information system
Dynamic stock and flow diagram
Information flow diagram, an illustration of information flow throughout an organisation.
Process flow diagram, in Operations, a graphical representation of a process
Product flow diagram (PFD), a graphical representation of the order by which a sequence of products is created according to Product based planning principles.
Sankey diagram, where line width represents magnitude
Signal-flow graph, in mathematics, a graphical means of showing the relations among the variables of a set of linear algebraic relations
State diagram, a representation of a finite state machine
