Abstract

A method of supporting creation of a quality function development chart which converts customer requirements to product characteristics urges input of customer requirements, urges input of product characteristics associated with the customer requirements, urges input of a degree of association of the customer requirements and the product characteristics, and urges input of a design quality for each of the product characteristics.

Claims

1. A supporting method for checking of a quality function development chart, comprising:

receiving a quality function development chart representing degrees of customer satisfaction of a plurality of products with respect to a customer requirement, benchmark values indicating actually measured values of the products with respect to a product characteristic, and a correlation chart representing a degree of association between the customer requirement and the product characteristic;

extracting maximum and minimum values of the degrees of customer satisfaction;

extracting maximum and minimum values of the benchmark values corresponding to the maximum and minimum values of the degrees of customer satisfaction;

generating an equation representing a value relationship between the degrees of customer satisfaction and the benchmark values, using the maximum and minimum values of the degrees of customer satisfaction and the benchmark values of the maximum and minimum values;

calculating guideline values of design qualities when the degrees of customer requirement are consistent with target quality values, using the equation; and

displaying the guideline values of design qualities.

2. A program stored in a computer-readable medium, for supporting checking of a quality function development chart, the program comprising:

means for instructing a computer to receive a quality function development chart representing degrees of customer satisfaction of a plurality of products with respect to a customer requirement, benchmark values indicating actually measured values of the products with respect to a product characteristic, and a correlation chart representing a degree of association between the customer requirement and the product characteristic;

means for instructing a computer to extract maximum and minimum values of the degrees of customer satisfaction;

means for instructing the computer to extract maximum and minimum values of the benchmark values corresponding to the maximum and minimum values of the degrees of customer satisfaction;

means for instructing the computer to generate an equation representing a value relationship between the degrees of customer satisfaction and the benchmark values, using the maximum and minimum values of the degrees of customer satisfaction and the benchmark values of the maximum and minimum values;

means for instructing the computer to calculate guideline values of design qualities when the degrees of customer requirement are consistent with target quality values, using the equation; and

means for instructing the computer to display the guideline values of the design qualities.

3. A supporting method for checking of a quality function development chart, comprising:

receiving a quality function development chart representing customer requirements, customer importance ratings, product characteristics, and a correlation chart representing degrees of association between the customer requirements and the product characteristics;

calculating a first reference priority of product characteristics in accordance with an independent weighting scheme, the first reference priority depending on corresponding one of the customer importance ratings and on corresponding one of the degrees of association;

calculating a second reference priority of product characteristics in accordance with a proportional weighting scheme, the second reference priority depending on corresponding one of the customer importance ratings and on corresponding one of the degrees of association;

calculating a guideline value represented by a total sum of an absolute value of a difference between the first and second reference priorities of product characteristics; and

displaying a waning message indicating that the degrees of association between the customer requirements and the product characteristics are not preferable, if the guideline value exceeds a threshold value.

4. A program stored in a computer-readable medium, for supporting checking of a quality function development chart, the program comprising:

means for instructing a computer to receive a quality function development chart representing customer requirements, customer importance ratings, product characteristics, and a correlation chart representing degrees of association between the customer requirements and the product characteristics;

means for instructing the computer to calculate a first reference priority of product characteristics in accordance with an independent weighting scheme, the first reference priority depending on corresponding one of the customer importance ratings and on corresponding one of the degrees of association;

means for instructing the computer to calculate a second reference priority of product characteristics in accordance with a proportional weighting scheme, the second reference priority depending on corresponding one of the customer importance ratings and on corresponding one of the degrees of association;

means for instructing the computer to calculate a guideline value represented by a total sum of an absolute value of a difference between the first and second reference priorities of product characteristics; and

means for instructing the computer to display a waning message indicating that the degrees of association between the customer requirements and the product characteristics are not preferable, if the guideline value exceeds a threshold value.
