Abstract

A system, method, and computer program for determining a quantity mismatch report so that a plurality of configured quantities for a plurality of product variants can be compared, comprising the steps of transforming a plurality of logical expressions; detecting a quantity mismatch report from said transformed logical expressions; and determining at least one product variant from said quantity mismatch report and appropriate means and computer-readable instructions.

Claims

1. A method of determining a quantity mismatch report so that a plurality of configured quantities for a plurality of product variants can be compared, comprising the steps of:

transforming a plurality of logical expressions;

detecting a quantity mismatch report from said transformed logical expressions; and

determining at least one product variant from said quantity mismatch report.

2. The method of claim 1, wherein said transforming step comprises the step of subtracting a first logical expression from a second logical expression using a truth table, whereby a combination of lines in said truth table having a true expression is translated into a minterm table.

3. The method of claim 2, wherein said transforming step further comprises the step of minimizing said minterm table by calculating a plurality of prime implicants.

4. The method of claim 1, wherein said detecting step utilizes a prime implicant table in positional cube notation to identify a plurality of equivalent primitives.

5. A computer-program product tangibly embodied in a machine readable medium to perform a method to determine a quantity mismatch report, comprising:

instructions for transforming a plurality of logical expressions;

instructions for detecting a quantity mismatch report from said transformed logical expressions; and

instructions for determining at least one product variant from said quantity mismatch report.

6. The computer-program product of claim 5, wherein said transforming instructions comprises instructions for subtracting a first logical expression from a second logical expression using a truth table,

wherein a combination of lines in said truth table having a true expression is translated into a minterm table.

7. The computer-program product of claim 6, wherein said transforming instructions further comprises instructions for minimizing said minterm table by calculating a plurality of prime implicants.

8. The computer-program product of claim 5, wherein said detecting instructions utilize a prime implicant table in positional cube notation to identify a plurality of equivalent primitives.

9. A data processing system having at least a processor and accessible memory to implement a method to determine, comprising:

means for transforming a plurality of logical expressions;

means for detecting a quantity mismatch report from said transformed logical expressions; and

means for determining at least one product variant from said quantity mismatch report.

10. A method of determining a quantity mismatch report comprising the steps of:

transforming a plurality of logical expressions, comprising the steps of;

subtracting a first logical expression from a second logical expression using a truth table, whereby a combination of lines in said truth table having a true expression is translated into a minterm table; and

minimizing said minterm table by calculating a plurality of prime implicants;

detecting a quantity mismatch report from said transformed logical expressions using a prime implicant table in positional cube notation to identify a plurality of equivalent primitives; and

determining at least one product variant from said quantity mismatch report.
