Note that the screen on which the difference between the input specification and the similar specification shown in FIG. 7 is output may be provided in the plant book display unit 106, or may be provided in another display unit not shown in FIG. It may be a screen. Specifically, since the information about which municipality is intended is the same and there is no difference, “difference for municipality” is set to “none”. Since the numerical information of the standard high water level is “40” in the input specification and “50” in the specification 3 shown in FIG. 4, the “standard high water level difference” is “10”.

  The second difference calculation unit 108 calculates the difference between the similar specification given by the similar specification search unit 103 and all past specifications stored in the plant specification storage unit 102 (see step ST4 in FIG. 3). Here, the difference between the specification 3 shown in FIG. 4 as a similar specification and the specification 1, specification 2, specification 3 and specification 4 shown in FIG. 4 is calculated.

  The relevance calculation unit 109 calculates the strength of the relevance between the difference given by the first difference calculation unit 107 and the difference given by the second difference calculation unit 108 (see step ST5 in FIG. 3). Here, the strength of the degree of association between the difference shown in FIG. 7 and the difference 1, difference 2, difference 3 and difference 4 shown in FIG. 8 is calculated.

  Here, as the relevance level of “difference for local governments”, it is calculated whether or not the difference exists, and as the relevance level of “standard high water level difference”, it is calculated whether or not the difference exists. The result shown in FIG. 9 is obtained. The degree of association 1 is obtained as the degree of association between the difference shown in FIG. 7 and the difference 1 shown in FIG. Further, the relevance level 2 is obtained as the relevance level between the difference shown in FIG. 7 and the difference 2 shown in FIG. Further, the degree of association 3 is obtained as the degree of association between the difference shown in FIG. 7 and the difference 3 shown in FIG. Further, the degree of association 4 is obtained as the degree of association between the difference shown in FIG. 7 and the difference 4 shown in FIG. It should be noted that the screen on which the relevance level of “difference for local government” and the relevance level of “standard high water level difference” shown in FIG. 9 may be provided in the plant book display unit 106. It may be a screen provided in another display unit not shown in FIG.

  The relevance 1 is the relevance of “difference for local government”, that is, the difference of “difference for local government” does not match, and the relevance of “standard high water level difference”, that is, the difference of “standard high water level difference” The presence or absence is consistent. As for the degree of relevance 2, the degree of relevance of “difference for local governments” is inconsistent, and the degree of relevance of “standard high water level difference” is coincident. As for the degree of association 3, the degree of association of “difference for local government” is the same, and the degree of association of “standard high water level difference” is inconsistent. The relevance level 4 is the same as the relevance level of “difference for local government”, and the relevance level of “standard high water level difference” is the same.

  Based on the relevance calculated by the relevance calculation unit 109, the related specification extraction unit 110 extracts, from the plant specification storage unit 102, a past specification that gives the strongest difference as a related specification (step ST6 in FIG. 3 is performed). reference). It is assumed that the strength of the association is stronger, for example, as there is more “matching” information. Here, among the relevance 1, relevance 2, relevance 3 and relevance 4 shown in FIG. 9, the relevance of “difference for local government” and “standard high water level difference” are the most relevant. The relevance level 4 with the same relevance level is selected, and the specification 4 is extracted from the specifications shown in FIG.

  The related book extracting unit 111 extracts a past book corresponding to the related specification extracted by the related specification extracting unit 110 from the plant book storage unit 104 as a related book (see step ST8 in FIG. 3). Here, the book 4 shown in FIG. 5 corresponding to the specification 4 shown in FIG. 4 is extracted as a related book.

  The inter-book difference extracting unit 112 extracts a difference between the similar book provided by the similar book extracting unit 105 and the related book provided by the related book extracting unit 111 (see step ST9 in FIG. 3). Here, the difference between the book 3 shown in FIG. 5 as a similar book and the book 4 shown in FIG. 5 as a related book is extracted.

  FIG. 10 is a diagram showing a screen display example of the calculation result of the difference calculation, that is, the result of calculating the difference between the similar book and the related book. When the difference between the book 3 shown in FIG. 5 and the book 4 shown in FIG. 5 is extracted, there is no difference in the “alarm activation if the water level is 90 or more”. It can be seen that there is a difference between the parts of the book 4 "starting the drain pump if the water level is 50 or more" and "starting the drain pump if the water level is 60 or more" in Book 4. In FIG. 10, “the portion where the difference occurs” is indicated by a circle.

  The plant book display unit 106 displays the similar books extracted by the similar book extraction unit 105 (see step ST10 in FIG. 3), and the “difference has occurred” shown by the inter-book difference extraction unit 112. "Part" is clearly indicated on the display of similar books (see step ST11 in FIG. 3). Here, on the display of the book 3 shown in FIG. 5 as a similar book, the “part where the difference occurs” shown in FIG. 10 (that is, the part shown by a circle in FIG. 10) is displayed. Make it explicit.

  FIG. 11 is a diagram showing a screen display example in a state where the result of the display, that is, the “part where the difference is generated” is clearly shown on the display of the similar books. The “part where the difference is generated” shown on the display of the book 3 is clearly shown surrounded by a rectangle.

  Next, the validity of the display result shown in FIG. 11 will be described. The past book shown in FIG. 5 is derived from the past specification shown in FIG. 4 according to the following simple rule.

  That is, “For municipality A, if the water level is 80 or higher, the alarm is activated”, “For municipality B, if the water level is 90 or higher, the alarm is activated” and “If the water level is higher than the standard high water level, the drain pump is activated” It is a rule.

  According to the above rules, the book corresponding to the specification of the plant to be designed is obtained by changing the numerical value “50” of the portion clearly shown by the rectangle in FIG. 11 to “40”. Therefore, according to this embodiment, it turns out that the effect that the part which should be changed is specified arises.

  The actual plant design is very complicated in both specifications and books, and the above rules are often not clear. Therefore, even if similar specifications are known from input specifications, it is often not clear which part should be changed in similar books corresponding to similar specifications. In this embodiment, by paying attention to the difference between the specifications of the plant created and accumulated in the past and the book of the plant corresponding thereto, even if such a rule is not clarified, “difference is By indicating the “occurring part”, it is possible to clearly indicate the part to be changed in accordance with the input specification.

  Note that in this embodiment, changes in specifications are reflected in changes in books, so if there are similar changes in specifications in the past, the parts of the books that were changed accordingly will also be changed in this specification change. This is based on the prediction that there is a high possibility of being subject to The action by each functional unit shown in FIG. 1 is to extract such a book difference.

  As described above, according to the present embodiment, when the past specification as shown in FIG. 4 and the past book as shown in FIG. 5 are stored in the storage device, it is shown in FIG. When such a plant specification is given, it is possible to specify a book to be a starting point of design and development, and a part to be changed corresponding to the input specification shown in FIG. Therefore, the plant designer can smoothly proceed with the design and further development of the plant by referring to the display.
