IDEF0, a compound acronym is a function modeling methodology for describing manufacturing functions, which offers a functional modeling language for the. Overview. IDEFØ is a method designed to model the decisions, actions, and activities of an organization or system. IDEFØ was derived from a well- established. Function Modeling (IDEF0) as a Federal Information Processing Standard (FIPS). to utilize the IDEF0 modeling technique, by implementors in.

IDEF0 stands for Integration Definition for Process Modelling, a public-domain methodology used to model businesses and their processes so they can be understood and improved.
IDEF0 diagrams typically include the following components:. Node trees—Tree-like structures of nodes rooted at a chosen node and used to represent a full IDEF0 decomposition in a single diagram.
In Visio and newer versions: You can also type a title and number for the diagram. Select the distance you want the title block border offset from the outside edge of the page, and then click OK. In the Shape Tutoral dialog box, type a name for the process.
IDEF0 – Part 1 (understanding it)
For Process IDuse the default, A0, to represent the top-level process. From IDEF0 Diagram Shapesdrag 1 legged connector shapes onto the drawing page and drag their endpoints to connection points on activity boxes. Drag the side selection handle to stretch the text block across the width of the title block. With the shape selected, type text to describe the viewpoint and purpose of the model you’re creating. In the Shape Data dialog box, type a node name, such as A0 for the top-most parent diagramor type the node number of the parent function box for example, A3 or A if this parent diagram is also a child diagram.
You can also type a title and number. In the Shape Data dialog box, type a name for the process the box represents.
The name should be an active verb or verb phrase. The sub-diagram ID can be a node number, such as A42, or the page number or name of the child diagram. Continue dragging, naming, and numbering activity boxes until you’ve placed between three and six boxes in the title block. Add constraint arrows and modify them the way you want.
Use the IDEF0 connector shape to:. When the endpoints turn red, the shapes are connected. Drag a second IDEF0 connector onto the page and drag its begin point to a connection point on another activity box.
Place the arrowhead of the second connector directly on top of the arrowhead of the first connector, so that the two arrows appear joined together. Drag a second IDEF0 connector onto the page and align its begin point with the begin point of the first connector.
Drag the end point up or down until the arrows fork the way you want. Drag an IDEF0 connector onto the drawing page, and then drag the begin point to a connection point on an activity box.
When the begin point turns red, the shapes are connected. With the connector selected, hold down the CTRL key and drag a copy of the connector to the place where you want the first branch. Connect the end points of the branches to the appropriate activity boxes. To better align fanned out branches, connect the begin points of the duplicate branches to the begin point of the original branch. If your branches have two bends, idet0 can also use the control handle to reposition the center leg of the connector.
To add a tunnel, right-click the connector, and then click Tunnel In or Tunnel Out. To remove a tunnel, right-click the connector, and then click Tunnel In or Tunnel Out to clear the check box.
IDEFØ – Function Modeling Method – IDEF
Use the 1 legged connector shape to add straight-line arrows to an IDEF0 diagram. In the Shape Data dialog box, type A0 or the node number or name of the node at which you want the tree rooted, and then click OK.
To add a text label to a node, drag a Text block 8pt shape onto the drawing page. With the text block selected, type a label. Drag a Solid connector shape onto the drawing page. Glue one endpoint to the connection point at the center of the node.
Drag the other endpoint until the connector is tutoriaal length you want and points in the direction you want. Repeat step 3 until you have added all the branches you need for nodes that will be connected to the top node. Drag other Node tugorial onto the drawing page and glue their centers to the free ends of the connectors. Tuhorial your way down the tree, repeating steps 3, 4, and 5, until you have added all the nodes and connectors you need.
In the Shape Data dialog box, type the number you want, and then click OK. If you want to be able to jump directly from a node to the detailed diagram that describes it, add a hyperlink to the node, and then link it to the drawing page that contains the detailed diagram.
