A method of knowledge-based engineering cost and weight estimation of an HVAC air-handling assembly for a climate control system on a vehicle includes the steps of selecting a parametric model of an HVAC air-handling assembly design using a knowledge-based engineering library stored in a memory of a computer system. The method also includes the steps of selecting a component part from the parametric model of the HVAC air-handling assembly, determining a cost estimate of the component part using the knowledge-based engineering library and using a summation of the component part cost as the cost estimate of the HVAC air-handling assembly. The method further includes the steps of determining a weight estimate of the component part using the knowledge-based engineering library and using a summation of the component part weight as the weight estimate of the HVAC air-handling assembly. The method further includes the steps of using the cost and weight estimate in the HVAC air-handling assembly design.

DETAILED DESCRIPTION Accordingly, the present invention is a method of knowledge-based engineering cost and weight estimation of an HVAC air-handling assembly for a climate control system on a vehicle.
The method includes the steps of selecting a parametric model of the HVAC air-handling assembly design using a knowledge-based engineering library stored in a memory of a computer system and selecting a component part from the model of the HVAC air-handling assembly.
The method also includes the steps of determining a cost estimate of the component part using the knowledge-based engineering library and using a summation of the component part cost as the cost estimate of the HVAC air-handling assembly.
The method further includes the steps of determining a weight estimate of the component part using the knowledge-based engineering library and using a summation of the component part weight as the weight estimate of the HVAC air-handling assembly.
The method further includes the steps of using the cost and weight estimate in HVAC air-handling assembly design.
One advantage of the present invention is that an improved method of knowledge-based engineering cost and weight estimation of an HVAC air-handling assembly for a climate control system on a vehicle is provided that considerably reduces design time and related expenses.
Another advantage of the present invention is that a method of knowledge-based engineering cost and weight estimation of an HVAC air-handling assembly for a climate control system on a vehicle is provided that utilizes parametric automated design in light of predetermined design, manufacturing and engineering criteria.
Yet another advantage of the present invention is that a method of knowledge-based engineering cost and weight estimation of an HVAC air-handling assembly for a climate control system on a vehicle is provided that allows analysis of an occupant's thermal comfort early in the design process using knowledge-based design rules and parametric constraints.
Still another advantage of the present invention is that a method of knowledge-based engineering cost and weight estimation of an HVAC air-handling assembly for a climate control system on a vehicle is provided which supports computer-aided engineering analysis (CAE) and rapid prototyping
