Studio III.5 Introduction to IBMS/IDEF Tool

This studio introduces the IDEF tool of the IBMS CASE system. The tool helps the users drawing an IDEF0 diagram.

Objective

  • Learn how to create an IDEF0 diagram using IBMS/IDEF tool.

Steps to start the IBMS/IDEF modeling tool:

  • Double click on the IBMS icon. You will see the welcome screen (with the moving spaceship). Click anywhere inside the welcome screen to bring up the first screen.
  • Under "tools", select IDEF Modeling. The IBMS will pop up the IDEF0 Modeler window. Its menu bar has the File, Edit, Tool, and Help options. Its tool box on the right contains 10 icons, representing (from left to right and top to bottom) pointer, cut, subject, text, flow, anchor point, zoom-out, zoom-in, decompose, and compose operations, respectively.

Working with IBMS/IDEF modeling tool:
Scenario:

  • Suppose we want to draw the level 1 IDEF0 as shown in Figure 5.1 and the level 2 in Figure 5.2 where the Subject S1 is decomposed into S11 and S12:

Figure 5.1: The level 1 IDEF0 diagram

Figure 5.1: The level 1 IDEF0 diagram

Figure 5.2: The level 2 IDEF0 diagram

Figure 5.2: The level 2 IDEF0 diagram

Steps:
To draw the level 1 IDEF0 diagram in Figure 5.1:

  • Left click on the Subject icon in the tool box and place it on the work area. The input dialogue box will prompt you to input information of the subject. Key in S1 as Subject Name for the Subject you just created.
  • Left click on the Subject icon in the tool box and place it on the work area. The input dialogue box will prompt you to input information of the subject. Key in S2 as Subject Name for the Subject you just created.
  • Left click on the Text icon in the tool box and place it over the subject S1. The input dialogue box will prompt you to input information of the text. Key in F1 as Text for the text you just created.
  • Left click on the Flow icon in the tool box, left click on the text F1, and left click on the subject S1.
  • Left click on the Text icon in the tool box and place it next to the subject S2. The input dialogue box will prompt you to input information of the text. Key in F4 as Text for the text you just created.
  • Left click on the Flow icon in the tool box, left click on the subject S2, and left click on the text F4.
  • Left click on the Flow icon in the tool box, left click on the subject S1, and left click on the subject S2. Left click on the Pointer icon in the tool box, left click on a point on the flow (this point is automatically assigned as an anchor point), and move the anchor point to get the flow as desired.
  • Left click on the Text icon in the tool box and place it over to the flow you just created in the previous. The input dialogue box will prompt you to input information of the text. Key in F2 as Text for the text you just created.
  • Left click on the Flow icon in the tool box, left click on the subject S2, and left click on the subject S1. Left click on the Pointer icon in the tool box, left click on a point on the flow that you want it to be an anchor point, and move the anchor point to get the flow as desired.
  • Left click on the Text icon in the tool box and place it under to the flow you just created in the previous. The input dialogue box will prompt you to input information of the text. Key in F3 as Text for the text you just created.

To assign an anchor point on a flow:

  • Left click on the Anchor Point icon in the tool box and left click on a point (you want it to be an anchor point) on a flow.

To change a direction of a flow:

  • Right click on a flow and confirm changing its direction.

To move subjects and texts:

  • Left click on the Pointer icon in the tool box, point to the subject/text, and hold LeftBotton to move to the new location desired in the work area and drop it there (release the LeftBotton)

To edit information of subjects and texts:

  • Right click on the subject/text. The input dialogue box will prompt you to edit information of that component.

To remove the IDEF0 components:

  • Left click on the Cut icon in the tool box, and left click on the IDEF0 component you want to remove. The confirmation box will prompt you to confirm the removal.

To zoom-in and zoom-out the IDEF0 diagram:

  • Left click on the Zoom-In (Zoom-Out) icon in the tool box, and left click on the work area. The IBMS/IDEF tool will zoom in (zoom out) the IDEF0.

To draw the level 2 IDEF0 diagram in Figure 5.2:

  • Left click on the Decompose icon in the tool box, left click on the subject S1, and draw IDEF0 diagram in Figure 5.2.

To save the IDEF0 diagram:

  • Under File menu, choose Save or SaveAs. Input the name and extension of the IDEF0 (the default extension is IDF) and specify folder for the IDEF0 to be saved. Then click OK.

To print the IDEF0 diagram:

  • Under File menu, choose Print. Input appropriate information. Then click OK.

To write report:

  • Under File menu, choose Write Report. Input appropriate information. Then click OK.

To save the IDEF0 diagram in other graphic formats using Paint program of MS Window:

  • Open the IDEF0 and display the desired diagram. Press PrintScreen button to get the screen in memory buffer.
  • Click Start, choose Program->Accessories->Paint. Under the Edit menu of Paint program, choose Paste to paste the screen shot from memory buffer into the work area. Modify the picture as desired and then save in an appropriate graphic format.
