Abstract
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.
