Structure Comparison 

Use

The function for comparing structures enables you to compare two structures or substructures in Integrated Product and Process Engineering (iPPE) and identify which nodes are used in both structures.

Features

·        You can compare where nodes are used. The system compares the nodes and their subordinate structures. Alternatives and variants of nodes can also be taken into account. It presents the results in a table.

·        On the initial screen, there are three different options for the structure comparison.

¡        Single-level structure comparison

The system compares the nodes directly below the node entered.

¡        Structure comparison on all levels

The system compares all the nodes below the node entered, regardless of how many levels each structure has.

¡        Structure comparison to a specific level

The system compares all the nodes below the node entered as far as the specified level.

·        Objects that are used in both structures are highlighted in a different color in the results table.

·        You can filter the results from single-level and multi-level structure comparisons using the following options:

¡         Only the intersection is displayed of all the nodes that are in both structures.

¡         A delta is displayed, that is, nodes that are in only one of the structures.

¡         / The system searches for and displays the selected node in the other structure.

This enables you to choose whether only the nodes that occur in both structures are displayed or only the nodes that occur in one structure. You can also search for individual nodes.

Actions

To compare structures, proceed as follows:

...

       1.      In the iPPE Workbench Professional, select Environment ® Evaluations ® Structure Comparison.

The dialog box Structure Comparison: Selection appears.

       2.      Select a radio button to specify the scope of the comparison. Enter the nodes that you wish to compare in Structure 1 and Structure 2, as well as their class and class type.

       3.      If necessary, set the indicators for Consider Alternatives and Consider Variants and choose  Start.

       4.      The screen with the results of the structure comparison appears.

You can also start a structure comparison by right-clicking one of the objects that you wish to compare in the navigation tree and selecting Structure Comparison in the context menu. The system transfers the selected object to Structure 1 in the dialog box Structure Comparison: Selection.
