Activity diagrams [1] are graphical representations of workflows of stepwise activities and actions [2] with support for choice, iteration, and concurrency. In the Unified Modeling Language, activity diagrams are intended to model both computational and organizational processes (i.e., workflows), as well as the data flows intersecting with the related activities.
A simple flowchart representing a process for dealing with a non-functioning lamp.. A flowchart is a type of diagram that represents a workflow or process.A flowchart can also be defined as a diagrammatic representation of an algorithm, a step-by-step approach to solving a task.
Dia has a modular design with several shape packages available for different needs: flowchart, network diagrams, circuit diagrams, and more.It does not restrict symbols and connectors from various categories from being placed together.
The 2009 edition was a major revision to IEEE 1016-1998, elevating it from recommended practice to full standard. This revision was modeled after IEEE Std 1471-2000, Recommended Practice for Architectural Description of Software-intensive Systems, extending the concepts of view, viewpoint, stakeholder, and concern from architecture description ...
ABC FlowCharter is a flowchart program originally from Texas-based Micrografx, Inc. [1] The trademark for this software was filed on August 25, 1989, and registered in January 1991. [2] It is also known as Micrografx FlowCharter and iGrafx FlowCharter. [3] Version 4.0 of ABC FlowCharter was released in 1995.
Figure 1: Functional flow block diagram format. [1] A functional flow block diagram (FFBD) is a multi-tier, time-sequenced, step-by-step flow diagram of a system's functional flow. [2] The term "functional" in this context is different from its use in functional programming or in mathematics, where pairing "functional" with "flow" would be ...
The beginning programmer would first create a flow chart to solve the problem. Since all of the problems involved words (rather than mathematical problems) the solution was intuitive. The flow chart would be translated into the flow programming language using a top-down, mechanical method.
The SFC standard is defined as Preparation of function charts for control systems, and was based on GRAFCET (itself based on binary Petri nets [1] [2]). It can be used to program processes that can be split into steps. Basic Batch SFC, with important elements labeled. Main components of SFC are: Steps with associated actions;
