Description

  The present invention relates to a product specification design apparatus.

  In order-made products such as plants and infrastructure equipment which are designed after receiving customer's required specifications, a product specification design apparatus that automatically determines the product specifications is often used in order to make the design work more efficient. This product specification design device requires a design rule for determining product specifications. As a background art of this design rule generation, there is JP 2010-128699 A (Patent Document 1). The design specification design apparatus of this publication outputs a device with a high matching rate of required specification items.

JP 2010-128699 A

  However, customers who require special specification values different from other customers for some required specification items (for example, the safety of the outer case material of products that handle corrosive gas is guaranteed by the standards. Even if there is a material, a customer who has a policy that emphasizes safety may desire a material that is stronger than the standard material). Since many of the customer's required specification items are standard specification values, standard design rules are adopted, resulting in standard product specifications ignoring customer policies.

In addition, not only the circumstances of the customer, the situation regarding the installation, for example, environmental measures at the installation area (wind, snow, flying sand measures, such as salt damage measures) and the presence or absence of the need for, EPC (E ngineering P rocurement C onstruction) contractors Appropriate product specifications vary depending on the construction capabilities of the supplier.

  An object of the present invention is to design a product specification corresponding to a project.

  In order to solve the above-described problems, the present invention provides a customer specification (for example, customer-specific specification information) or installation information (for example, installation) for the required specifications stored in the design performance DB and the product specifications for the required specifications. Categorize by region and EPC contractor, and use these categories as extraction conditions.

[Basic configuration]
FIG. 1 shows the configuration of the product specification design apparatus.

  The product specification design apparatus according to the present embodiment includes a calculation unit 101, an input / output unit 102, and a storage unit 103.

  The calculation unit 101 includes a category-specific rule generation unit 104 and a category-specific rule adoption determination unit 105. Details will be described later.

  The input / output unit 102 has a function of performing input / output through an input / output device.

  The storage unit 103 includes category-specific rule data 108, category classification priority data 109, rule adoption reference value data 110, design performance data 111, item category data 112, requirement specification data 113, and product specification data 114.

  The category-specific rules 108, the category classification priority 109, the rule adoption reference value 110, and the case category 112 are input or edited through the input / output unit 102 and stored in the storage unit 103.

The required specification data 113 is received from the case management system, and the design performance data 111 is received from the design data management system via a network (not shown), and stored in the storage unit 103.
[Basic processing flow]
FIG. 2 shows a processing flow. The category-specific rule generation unit 104 reads the rule adoption reference value 110, the design performance data 111, and the category classification priority data 109 from the storage unit 103, and generates the category-specific rule 108 based on them. The category-specific rule generation unit 104 stores the generated category-specific rule 108 in the storage unit 103.

The category-specific rule adoption determination unit 105 is based on the category classification priority data 109, the item category data 112, the required specification data 113, and the category-specific rules 108 created by the category-specific rule generation unit 104 from the storage unit 103. Then, product specification data 114 is generated and stored in the storage unit 105.
[Detailed flow of category-specific rule generation unit 104]
The processing contents of the category-specific rule generation unit 104 will be described with reference to the processing flowchart of FIG.

  First, the flow 301 selects a category category set in the category category priority data 109 from the design result data 111, and extracts data of a category target in the category category.

  FIG. 7 shows design result data 111 and FIG. 11 shows category division priority data 109. In the category classification priority data 109 shown in FIG. 11, customers, EPCs, regions, and standards are registered as category classifications. The category category priority data 106 can be edited on the category category priority editing screen 106 shown in FIG. The category division priority editing screen 106 includes a menu 611 on the left side and a screen 612 showing the priority for each category generated from the category division priority data 109 on the right side. From the top, the menu includes priority order storage, new category registration, and category deletion. The user can select this menu, and can add, delete, and modify rule data, category data, and category classification priority data by category. When a change occurs, each data in the storage unit 103 is updated. Will be.

  A case will be described where “customer” is selected as the category classification for which rules are generated first.

  Reference is made to design performance data 111 shown in FIG. The design record data 111 stores installation information related to installation of equipment and customer information for specifying the customer's original specifications. In the present embodiment, as the installation information, the EPC business name is stored in the category classification “EPC”, and the installation area is stored in the category classification “region”. In the present embodiment, items of “customer name”, “required specification / specification gas type”, and “required specification / pipe material” are set as customer information. When the customer of the target product for product design is “Company A”, data of case Nos. 1, 2, 3, and 4 in which the category classification “customer name” is data of “Company A” are extracted.

  Next, the flow 302 is performed. First, a combination of the required specification value and product specification value of the extracted design performance data is obtained. Here, when the extracted category classification is “customer” and the category target “customer name” is “Company A”, when “use gas type” is “CO2”, “pipe material” is “Stainless” ”, 2 data,“ CH4 ”is used, 1 data is“ Stainless ”and 1 data is“ Brass ”. . Therefore, there are three types of combinations of required specifications and product specifications. Then, the adoption rate and the number of data are tabulated for these three types of combinations. The tabulation results are shown in FIG. The adoption rate means the ratio of the corresponding product specifications to the same required specifications. In the example of FIG. 8, for the “use gas type CO2” that is the required specification, the product material “pipe material” is only Stainless, so the rate of adoption of the pipe material “Stainless” relative to the specification gas type CO2 is 100%. On the other hand, for the gas type CH4, the pipe materials are Stainless and Brass, so the adoption rate is 50% for both Stainless and Brass. At the same time, count the number of data.

  Next, the processing flow 303 will be described. The rule adoption reference value data 110 stores a reference as to which rule is adopted. FIG. 9 shows rule adoption reference value data 110. In this embodiment, the “adoption rate reference value” and the “data number reference value” are used as references. For each combination of “Required specification” and “Product specification”, the calculated adoption rate and the number of data are compared, and the combination is that the adoption rate is greater than the adoption rate reference value and the number of data is greater than the data number reference value. Is adopted as a design rule. As shown in FIG. 9, in this embodiment, the rule is that the adoption rate is 75% or more and the number of data is 2 or more. Therefore, according to the total result of FIG. ", The rule that the pipe material is" Stainless "is adopted. When a plurality of combinations satisfying the adoption standard value are extracted, the combination having the highest adoption rate is adopted as the design rule.

  Finally, in flow 304, it is determined whether or not calculation has been performed for all category divisions and category targets. If there is a category division or category target that has not been calculated, the flow 301 is returned to and calculation is performed.

  The calculated category-specific rules 108 can be confirmed and edited on the category-specific rule editing screen 107.

The category-specific rule editing screen shown in FIG. 5 includes a navigation 501 for tracing a design rule to be confirmed from the product configuration. When a design rule to be referred to is selected using this, the design rule display unit 503 displays category categories and category targets. Separately, combinations of required specifications and product specifications are displayed, and it is possible to confirm which combination was adopted based on the rule adoption reference value 110 set by the rule adoption reference value setting unit 502. If the combination adopted in the rule adoption standard value is not adopted in the design rule, or conversely, if the rule adoption standard value is not met, but there is a combination to be adopted as the design rule, edit whether to adopt it here. It can be carried out.
[Detailed Flow of Category-Based Rule Adoption Determination Unit 105]
A detailed flow of the category-specific rule adoption determination unit 105 will be described with reference to the processing flowchart shown in FIG.

  First, in the flow 401, the category division with the priority “1” is selected from the category division priority 109. In this embodiment, as shown in FIG. 11, “customer” is selected.

  Next, in a flow 402, the corresponding category classification rule is extracted from the category-specific rule data 108. FIG. 10 shows the category-specific rule data 108 of this embodiment. In this embodiment, there are a rule for determining “pipe material” and a rule for determining “presence / absence of a heat retaining mechanism”. Since there is a rule relating to “Company A” in the rule for determining “pipe material”, the rule is extracted. On the other hand, in the rule for determining “presence / absence of heat insulation mechanism”, there is no category classification rule of customer, so nothing is extracted.

  Next, in the flow 403, the category category 112 is checked against the extracted category category rule to determine the applicability of the rule. The item category data 112 of the present embodiment is shown in FIG. In this example, the category target for the category classification "customer" is "Company A", the category target for the category classification "EPC" is "Company J", and the category target for the category classification "Region" is "Middle East" Since there is a category object “Company A” of the category “Customer”, it is determined that the rule relating to “Company A” for determining the extracted “pipe material” is applicable. Further, when there is a rule determined to be applicable, the required specification value 113 of the rule determined to be applicable is checked against the required specification data 113 to determine whether or not the product specification value is adopted. FIG. 13 shows the required specification data 113 of this embodiment. In this example, the category classification “Used gas type” is “CO2” and matches the “Used gas type CO2” which is the required specification of the rule for determining the “Pipe material” of the extracted “Company A”. Adopting this rule, the product specification and “pipe material” is determined as “Stainless”.

  Then, whether or not the rule application determination has been calculated for all the category sections is determined in the flow 404, and if all the category sections have not been calculated, the next priority category section is selected and the process proceeds to the flow 405. Then, the next priority order of the category category targeted at that time and the set category category are selected, and the flow returns to the corresponding flow 402 to perform calculation.

  As shown in FIG. 11, “EPC” is set as the priority order “2” in this embodiment. As shown in FIG. 10, the only rule for determining “presence / absence of heat retaining mechanism” stored as the category classification “EPC” in the category-specific rule data 108 of this embodiment is “M company”. However, as shown in FIG. 12, in the case category data 112 of this embodiment, “EPC” is “Company J”, so this rule is not applied.

  Furthermore, as shown in FIG. 11, “region” is set as the priority order “3” of this embodiment. As shown in FIG. 10, the rule stored as the category classification “region” in the category-specific rule data 108 of this embodiment is only the rule relating to “Europe” that determines the pipe material. However, as shown in FIG. 12, in the case category data 112 of this embodiment, “Region” is “Middle East”, so this rule is not applied.

  Here, as a rule for determining the “pipe material”, a rule for “Middle East” is set, and the “use gas type” is “CO2” and the “pipe material” is “Brass”. If there is a match, the item category data 112 and the required specification data 113 are matched, but since the product specification has already been determined for the pipe material in the category “customer” of the priority “1”, the priority Low rules do not apply.

  Eventually, the standard category category rule is applied to the rule for determining the presence or absence of the heat retention mechanism, and in this embodiment, the site temperature of the required specification is 20 degrees, so the product specification without the heat retention mechanism is determined. Is done. The determined product specification data 114 is shown in FIG. The product specifications thus determined can be linked to various design support systems to calculate an estimated amount and create a drawing.

  The processing by the category-specific rule adoption determining unit 105 is executed when the product specification is determined after the required specification data 113 is updated after receiving the required specification from the customer. The processing at may be executed in advance.
