Creation of Functional Chains and Physical Paths
Functional Chains and Operational Processes
On an existing dataflow diagram, select all the Functional Exchanges contributing to your Functional Chain.
| - The selected elements must form a uninterrupted path of Functional Exchanges.
- The path of selected elements shall only have two end, which means that it can be composed by only one branch.
- Only Functional Exchanges must be selected.
|
Using the contextual menu on this multiple selection, click on Functional Chain / Create a Functional Chain
A new Functional Chain is created and displayed.
If you want to edit a Functional Chain, you have to create a Functional Chain Description diagram. You can create this diagram from a Navigate command in the contextual menu from a Functional Chain.
A new diagram is created, representing your Functional Chain. What you see on this diagram are not Functions and Exchanges but Functional Chain Involvement elements. This is a essentially a "working" diagram.
On the following diagram, the tools of the palette have been used to include a new Function and new Exchanges so that we have a branch.
- The “Involve Function” tool simply adds a new element representing a Function. It is the responsibility of the user to add the necessary Functional Exchanges in order to form a complete Functional Chain.
- The “Involve Functional Exchange” allows selecting a possible (already existing) Exchange between the selected source and target elements representing Functions.
- The “Involve Functional Chain” tool adds a new element representing a Functional Chain. It is the responsibility of the user to add the necessary Functional Exchanges in order to form a complete Functional Chain.
- The “Involve Functional Exchange and Target Function” is contextual to the selected source Function element: it allows creating at the same time both the elements representing an outgoing Exchange and the Target Function.
- The “Involve Functional Exchange and Target Functional Chain” is contextual to the selected source Function element: it allows creating at the same time both the elements representing an outgoing Exchange and the Target Functional Chain.
On the dataflow diagram, the result is the following.
Physical Paths
The same strategy applies for Physical Paths on System Architecture Blank and Logical Architecture Blank and Physical Architecture Blank diagrams.
| - The selected elements must form a uninterrupted path of Physical Links.
- This path shall only have two end, which means that it can be composed by only one branch.
- Only Physical Links must be selected.
