DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

The present embodiment has a function of retrieving a similar design document from existing design cases for a plant to be designed when designing a plant such as a rolling mill or a power plant.

FIG. 1 is a block diagram showing the configuration of a similar case extracting apparatus according to the present invention.

First, examples stored in the first database 10 are data of a plant design specification or a document such as a control logic diagram, and a first search key and a second search key associated therewith. , And the second search key is key data associated with the detector or actuator to be displayed or printed in the document. FIG. 2 shows an example of the data configuration of the case.

[0009] Regarding "case X" shown in FIG. 2, data used for the first search key and the second search key correspond to the module name and the device name, respectively. here,
The module name is the design specification of the design target plant,
Alternatively, it is data corresponding to the contents of a control logic diagram or the like. The device name is key data associated with a device such as a detector or an actuator displayed or printed in a document. If the first search key input unit 11 in FIG. 1 has input the above-mentioned module name, it is input to the first search unit 12.

The first search means 12 uses the module name of the first search key as a search key, and searches the case in the first database 10 for the case of the module name matching the module name of the first search key. Search for. First
The case searched by the search means 12 is temporarily stored in the first search result storage means 13. Second database 1
5 calls the key list. Here, an example of the key list is shown in FIG. If the plant currently being designed is “plant A”, the key list 31 is referred to. If the plant to be designed is “plant B”, the key list 31 switches accordingly.

The second search means 14 shown in FIG. 1 reads an example of the first search result stored in the first search result storage means 13 and searches the device name given from the case for a second search. As a key, the key list is compared with the key list, the number of device names of cases matching the device name of the key list is counted, and the value is held. This process is sequentially performed for all the cases stored in the first search result. After obtaining the number of device name matches of the case, the case with the largest number of device name matches is selected as a similar case. As a result, a similar case is output to the extraction result output means 16.

Next, each processing step will be described with reference to FIG.

First search key input step 41 in FIG.
If there is an input of the above-mentioned module name, this is input to the first search step 42. In the first search step 42, using the moshur name of the first search key as the search key, the case of the module name matching the module name of the first search key from the cases in the first database 10 of FIG. Perform the process of searching for. The case searched in the first search step 42 is stored in the first search result storage step 43.

The second database 15 in FIG. 1 calls the key list described above. Second search step 44 in FIG.
, The case of the first search result stored in the first search result storing step 43 is read, the device name given from the case is used as the second search key, and the result is compared with the key list. The number of device names of cases matching the name is counted, and the value is held.

This processing is sequentially performed for all the cases stored in the first search result. After obtaining the number of device name matches of the case, the case with the largest number of device name matches is selected as a similar case. As a result, extraction result output step 1
At 6, the similar case is output. Thus, in the present invention,
When performing a similar case search, the user does not need to input an enormous amount of data, and the input load of search conditions can be reduced.

[0016]

As described above, according to the present invention, a similar case search in which the input load of search conditions on the user side is reduced by reading a plurality of key data to be used for search from a key list held in a database is provided. it can.
