Project Planning System, Control Program and Method for Checking Consistent Recording of Pipelines in a Project Planning System

A method for checking the consistent recording of pipelines in a project planning system, the method comprising:

• recording pipelines two-dimensionally in a first plan and three-dimensionally in a second plan;
• determining at least one main path within each plan for each of the pipelines recorded in the first and second plans;
• determining sequences of objects comprising at least one of (i) line components, (ii) branches and (iii) connections for the main paths recorded within both plans which are each to be compared with one another;
• eliminating from sequences to be compared each object without a mutual correspondence which is at least one of (i) only recorded in one of the first and second plans and (ii) only recorded in one main path of one of the first and second plans;
• determining and classifying iteratively, after elimination of the objects without mutual correspondence, objects with different ordering within the sequences to be compared which have a maximum order difference with respect to their ordering within the sequences to be compared;
• continuing determining the objects with different ordering until all objects remaining after classification have no order difference with respect to their ordering within the sequences to be compared;
• creating a correctly ordered assignment between corresponding objects recorded in the first plan and second plans;
• and
• displaying the correctly ordered assignment between corresponding objects recorded in the first plan and second plans on a graphical user interface.

A project planning system, comprising:

• a processor;
• and
• memory;
• wherein the project planning system is configured to:
• record pipelines two-dimensionally in a first plan and three-dimensionally in a second plan;
• identify at least one main path within each plan for pipelines recorded in first and second plans;
• identify sequences of objects comprising at least one of (i) line components, (ii) branches and (iii) connections, which are each to be compared with one another for the main paths recorded within both plans;
• eliminate from the sequences to be compared objects without a mutual correspondence which are at least one of (i) only recorded in one of the first and second plans and (ii) only recorded in one main path of one of the first and second plans;
• iteratively identify and classify, within the sequences to be compared, objects with different ordering which have a maximum order difference with respect to their ordering within the sequences to be compared after elimination of the objects without mutual correspondence;
• continue determination of the objects with different ordering until all objects remaining after classification have no order difference with respect to their ordering within the sequences to be compared;
• create a correctly ordered assignment between corresponding objects recorded in the first plan and second plan;
• and
• display said correctly ordered assignment between corresponding objects recorded in the first plan and second plan on a graphical user interface.

• program code for creating a correctly ordered assignment between corresponding objects recorded in the first plan and second plans;
• and
• program code for displaying the correctly ordered assignment between corresponding objects recorded in the first plan and second plans on a graphical user interface.
