Abstract

A plurality of rule groups are stored in a hard disk (14) in advance, and each group generally includes a plurality of rules. A data file is stored on a floppy disk (16) and includes input- and output-variable data. The input- and output-variable data is a set of input-variable data and output-variable data, the latter of which is obtained when the input-variable data is applied and an operation in accordance with rules desired to be generated is carried out. The data file on the floppy disk (16) is read by a floppy disk drive (15). Using the input-variable data, the CPU (11) performs an operation in accordance with each rule group stored on the hard disk (14). The operational results and the output-variable data are compared and the degree of effectiveness of each rule group is calculated on the basis of the comparison. The best rule group is selected based upon the degree of effectiveness.

Claims

1. A rule generating apparatus comprising:

rule-group storage means in which plural groups of rules, each group including a plurality of rules, are stored in advance;

first input means for entering specifications for rule generation;

second input means for entering input-variable data and output-variable data used in rule generation;

first selecting means for selecting rule groups, which satisfy the specifications entered by said first input means, from among the rule groups stored in said rule-group storage means;

first operating means for performing operations, in accordance with respective ones of the rule groups selected by said first selecting means, using the input-variable data entered by said second input means;

second operating means for comparing operational results from said first operating means and the output-variable data entered by said the second input means, and calculating degree of effectiveness of each rule group; and

second selecting means for selecting an appropriate rule group on the basis of the degree of effectiveness obtained by said second operating means.

2. A rule generating apparatus according to claim 1, further comprising memory means for storing the rule group selected by said second selecting means.

3. A rule generating apparatus according to claim 1, further comprising an output unit for outputting the rule group selected by said second selecting means.

4. A rule generating apparatus according to claim 1, wherein said first input means comprises a recording medium storing specification data, and a reading device for reading the specification data from said recording medium.

5. A rule generating apparatus according to claim 1, wherein said second input means comprises a recording medium storing the input- and output-variable data, and a reading device for reading the input- and output-variable data from the recording medium.

6. A rule generating apparatus according to claim 1, which comprises a host device and a terminal device connected to the host device so as to be capable of communicating therewith;

the host device having said rule-group storage means, said first selecting means, said first operating means, said second operating means and said second selecting means; and

said terminal device having said first input means and said second input means.

7. A rule generating apparatus according to claim 1, which comprises a host device and a terminal device connected to the host device so as to be capable of communicating therewith;

said host device having said rule-group storage means; and

said terminal device having said first input means, said second input means, said first selecting means, said first operating means, said second operating means and said second selecting means.

8. A rule generating apparatus according to claim 1, which comprises a host device and a terminal device connected to the host device so as to be capable of communicating therewith;

said host device having said rule-group storage means and said first selecting means; and

said terminal device having said first input means, said second input means, said first operating means and said second selecting means.

9. A rule generating apparatus according to claim 1, wherein said specifications include essential matters and conditional matters;

said first selecting means selects rule groups that satisfy all of the essential matters; and

said first selecting means or said second selecting means selects rule groups on the basis of the conditional matters.

10. A rule generating apparatus comprising:

rule-group storage means in which plural groups of rules, each group including a plurality of rules, are stored in advance;

input means for entering input-variable data and output-variable data used in rule generation;

first operating means for performing operations, in accordance with respective ones of the rule groups stored in said rule-group storage means, using the input-variable data entered by said input means;

second operating means for comparing operational results from said first operating means and the output-variable data entered from said input means, and calculating degree of effectiveness of each rule group; and

selecting means for selecting an appropriate rule group on the basis of the degree of effectiveness obtained by said second operating means.

11. A rule generating apparatus according to claim 10, further comprising memory means for storing the rule group selected by said selecting means.

12. A rule generating apparatus according to claim 10, further comprising an output means for outputting the rule group selected by said selecting means.

13. A rule generating apparatus according to claim 10, wherein said input means comprises a recording medium storing the input- and output-variable data, and a reading device for reading the input- and output-variable data from the recording medium.

14. A rule generating apparatus according to claim 10, which comprises a host device and a terminal device connected to the host device so as to be capable of communicating therewith;

the host device having said rule-group storage means, said first operating means, said second operating means and said selecting means; and
