Arrow diagramming method (ADM) is a network diagramming technique in which activities are represented by arrows. [1] ADM is also known as the activity-on-arrow (AOA) method. Usage
Arrow diagram. This tool is used to plan the appropriate sequence or schedule for a set of tasks and related subtasks. It is used when subtasks must occur in parallel. The diagram helps in determining the critical path (longest sequence of tasks). The purpose is to help people sequentially define, organize, and manage a complex set of activities.
The precedence diagram method (PDM) is a tool for scheduling activities in a project plan. It is a method of constructing a project schedule network diagram that uses boxes, referred to as nodes, to represent activities and connects them with arrows that show the dependencies. It is also called the activity-on-node (AON) method.
A network diagram can be created by hand or by using diagram software. There are two types of network diagrams, activity on arrow and activity on node . Activity on node diagrams are generally easier to create and interpret. To create an AON diagram, it is recommended (but not required) to start with a node named start. This "activity" has a ...
Arrow's theorem assumes as background that any non-degenerate social choice rule will satisfy: [15]. Unrestricted domain — the social choice function is a total function over the domain of all possible orderings of outcomes, not just a partial function.
Event chains diagrams present events as arrows on the Gantt charts. Arrows pointing down are threats. Arrows pointing up are opportunities. Issues are shown as an arrow within a circle. Color of the issue arrow is red (dark). Closed or transferred risks are shown using dashed lines. Color of arrow is white.

State diagrams are directed multigraphs that represent finite-state machines. Commutative diagrams are digraphs used in category theory , where the vertices represent (mathematical) objects and the arrows represent morphisms, with the property that all directed paths with the same start and endpoints lead to the same result by composition.
