Filed:

Jan 31, 2000

Appl. No.:

09/495531

Inventors:

Yuan John Li - Novi MI
Mawutor Kofi Kpeglo - Canton MI
Yung-Sen Steven Shang - Canton MI

Assignee:

Visteon Global Technologies, Inc. - Dearborn MI

International Classification:

G06F 1700

US Classification:

706 45, 706 46

Abstract:

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.

International Classification:

G06G 748

US Classification:

703 8, 703 1, 345419

Abstract:

A method of optimized design of an HVAC air-handling assembly for a climate control system on a vehicle includes the steps of generating a basic design of the HVAC air-handling assembly and analyzing a performance of the basic design of the HVAC air-handling assembly using an engineering analytical technique. The method also includes the steps of varying the basic design of the HVAC air-handling assembly based on the performance analysis and using the optimized basic design of the HVAC air-handling assembly in generating the HVAC air-handling assembly design.
