Is used to register a new case ID in the required specification result data 220 of the required specification result data storage unit 123 in the form of a specification value ID, and store the data.

In step S102, the specification change proposal generation unit 112 searches the specification change proposal rule data 270 in the specification change proposal rule storage unit 125 using the received specification value ID of the required specification value, and the specification value of the required specification value. The data record of the specification change proposal rule that matches the ID is searched and assigned.
In step S103, the specification change proposal generation unit 112 displays the specification change proposal rule assigned in step S102 and the related specification change proposal rule on the specification change proposal confirmation screen shown in FIG.
For example, the specification change proposal rule indicated by the data record 402 in FIG. 13 requires that the customer's requirement specification is “one” for “filter”. In the case of “fuel” = “gas” and “gas type” = “LNG”, in the past results, since LNG is natural gas, a filter is unnecessary and the probability of “not attached” is 90%. Represents the proposed specification value. In addition, the specification change proposal rule indicated by the data record 403 indicates that when the proposed specification value is “gas type” = “off gas”, the off-gas is a gas mixed with impurities, so that the customer's required specification is “filter” “non-gas”. “Appendix” indicates that the proposed specification is proposed as “filter” or “1 unit” in the past case with a probability of 100%.

In step S104, the user confirms the specification change proposal confirmation screen shown in FIG. 13, and receives a customer's approval if a business negotiation with the customer is in progress, and applies the specification change proposal rule to be applied from the displayed candidates. Select and enter a check mark in the corresponding cell in the application column 311.
The specification change proposal generation unit 112 receives the result of the user's input / editing on whether or not to apply the specification change proposal rule on the specification change proposal confirmation screen shown in FIG.
In step S105, the proposed specification generation unit 113 converts the required specification value into the proposed specification value according to the applied specification change proposal rule based on the edited result in step S104, and displays the proposed specification output screen shown in FIG. indicate.

(11) Specification Change Proposal Rule Generation Processing FIG. 11 is a diagram showing a processing flow of specification change proposal rule generation.
In step S201, the specification change proposal rule generation unit 114 reads all the actual data stored in the proposed specification actual data 230 of the proposed specification actual data storage unit 124. Note that the specification change proposal rule may change with time (time), and in order to generate an appropriate specification change proposal rule according to the time (time) change, within the estimated date range specified by the user. The specification change proposal rule generation process may be performed by reading only the record data of the corresponding case.

  In step S202, the specification change proposal rule generation unit 114 uses the proposed specification result data 230 of the proposed specification result data storage unit 124, the conditional probability α resulting from the proposed specification value j as a condition, with the proposed specification value i as a condition. (Conditional probability that the proposed specification value j is also established for a case where the proposed specification value i matches in the target case group registered in the past) is calculated using the following formula 1, and the specification change proposal rule The proposed specification value conditional probability data 240 is stored in the storage unit 125.

p(Yj|Xi)：提案仕様値iがXiとなる条件下で提案仕様値jがYjとなる確率
p(Xi∩Yj)：提案仕様値iがXiかつ提案仕様値jがYjとなる確率
p(Xi)：提案仕様値iがXiとなる確率

p (Yj | Xi): Probability that the proposed specification value j is Yj under the condition that the proposed specification value i is Xi
p (Xi∩Yj): Probability that the proposed specification value i is Xi and the proposed specification value j is Yj
p (Xi): Probability that the proposed specification value i is Xi

  In step S203, the specification change proposal rule generation unit 114 specifies a conditional probability of the proposed specification value conditional probability data 240 in the specification change proposal rule storage unit 125 that is equal to or higher than a threshold a (for example, 0.80), and The cell to be converted is converted to “1”, and the non-applicable cell is converted to “0” and stored as the proposed specification value dependency relationship data 250 in the specification change proposal rule storage unit 125. With this process, the post-processing combination calculation can be narrowed down to a meaningful calculation area having a dependency relationship, and can be limited to a realistic calculation time (for example, several seconds to several hours).

  In step S204, the specification change proposal rule generation unit 114 reads all the actual data stored in the required specification actual data 220 of the required specification actual data storage unit 123. Note that, in the case where only the actual data of the case corresponding to the estimated date range specified by the user is read in the proposed specification actual data 230 in the step S201, the actual data of the same case is also read in this processing.

In step S <b> 205, the specification change proposal rule generation unit 114 includes the required specification result data 220 in the required specification result data storage unit 123, the proposed specification result data 230 in the proposed specification result data storage unit 124, and the specification change proposal rule storage unit 125. Using the proposed specification value dependency relationship data 250, a proposal of the same specification item as the required specification value i is made on the condition of a proposed specification value group (k ₁ ,..., K _n ) having a dependency relationship with the required specification value i. The conditional probability β resulting from the specification value j is calculated using the following formula 2 and stored in the specification change proposal conditional probability data 260 of the specification change proposal rule storage unit 125. The specification change proposal for the requirement specification is not only the requirement specification value of the specification item but also the specification value condition of other specification items (the proposed specification value having the dependency stored as the proposed specification value dependency relationship data 250 in step S203). In many cases, the proposed specification values proposed to change the specifications differ. By performing this processing, a specification change proposal rule including those conditions can be generated.

  As described above, according to the present system (estimated configuration design apparatus 100), a proposed specification value with a high probability of specification change is proposed to a customer based on past performance information with respect to a customer's required specification value. By proposing the specification change to the proposed specification value that combines the company's standard specifications, cost reduction and delivery time can be shortened. Also, by accessing and utilizing this system from a mobile terminal, the required specification values can be input, for example, at the meeting with the customer, and the specification change proposal output can be obtained in real time, thereby prompting the proposal to the customer. It is possible to expand the ordering opportunities by making it easier.
