Hereinafter, examples will be described with reference to the drawings.

  FIG. 1 is an overall system configuration diagram of a configuration design apparatus 100 and peripheral devices according to the present embodiment.

  This system includes a configuration design device 100 and peripheral devices (communication device 170, remote input / output device 180, communication network 181 and input / output device 190).

  The input / output device 190 is for inputting specification value data and outputting related design information, and is preferably composed of a keyboard, mouse, display, printer, etc., which are general input / output devices of a computer. However, the apparatus configuration is not limited to these.

  The remote input / output device 180 is for inputting / outputting data at a remote place. The processing contents are the same as those of the input / output device 190, but for data exchange with the product information management device 100, the communication device 170 and the communication network 181 are interposed therebetween.

  The input / output interface 191 is a part of the product information management device 100 of the present invention, and performs data communication between the remote input / output device 180 and the input / output device 190 and each part of the configuration design device 100.

  The configuration design device 100 is configured to include a storage device 120, a calculation device 140, and an input interface 191 that is connected to an external peripheral device.

Hereinafter, each configuration of the configuration design apparatus 100 will be described in detail.
<Configuration of storage unit 120>
The storage device 120 includes a configuration determination rule storage unit 121, a change method storage unit 122, and a required specification storage unit 123.

  The configuration determination rule storage unit 121 is a part that stores rules for estimating and designing a configuration based on required specifications. FIG. 2 is an example of a data table stored in the configuration determination rule storage unit 121. The column heading of the first column of the data table is “No.” of the configuration determination rule, and the column headings of the second column and thereafter are “rule group”, “rule level”, “condition part”, “execution part” in this order. "

  “Rule group” is data indicating the group of each rule, “rule level” is data indicating the level of the rule according to the contents of “condition part” or “execution part” in “rule group”, The “condition part” stores data indicating the condition of the specification for executing the rule, and the “execution part” stores data indicating the contents to be executed when the condition is satisfied. The rule registered in the first row (No. 301) of the data area is explained. In the rule in which the “rule level” of “method determination” is classified as “0”, the requested “input BOD” When the value satisfies 300 or more, it indicates that the “aggregation and precipitation” method is selected as the “treatment method”.

  After the configuration plan is generated, the change method storage unit 122 evaluates the configuration plan, and stores the rule group to be changed and the rule level change amount among the configuration determination rules to be applied when the required specifications are not satisfied. Part. FIG. 3 is an example of a data table stored in the change method storage unit 122.

  The column heading of the first column of the data table is “No.” of the configuration determination rule, and the column headings of the second and subsequent columns are “required specification item”, “required specification achievement status”, “change target rule group in order,” “Applicable rule level change degree”. “Required specification item” is the data of the required specification to be evaluated, “Required specification achievement status” is the data indicating how much the evaluation result has not achieved the required specification, and “Change target rule group” is the target of change. “Applied rule level change degree” is data indicating how much the “rule level” applied in the “rule group” is changed.

  Explaining the rules registered in the first row (No. 401) of the data area, when the required specification achievement status of the required specification item “output BOD (biochemical oxygen demand)” satisfies “30% or less” Indicates that it is selected that the rule group “equipment specification determination” is to be changed and that the rule of the applied rule level “+1” or lower is applied.

  The required specification storage unit 123 is a part in which specifications required by customers and specifications that become conditions for new designs are stored. FIG. 4 is an example of a data table stored in the required specification storage unit 123. In the present embodiment, “required specification item” and “required specification value” are heading items.

  In the case of the present embodiment, “input BOD” is data indicating an input specification that is an input of a product, “output BOD” is data indicating a performance value that is a target specification to be achieved by the product, and “processing time” is required for processing. Data indicating time, “price” is data indicating product price.

  In this example, “input BOD” is “400”, “output BOD” is “100 or less”, “processing time” is “20 h or less”, and product “price” is “13,000 or less” as required specification data. Indicates that it has been accepted.

  The arithmetic device 140 includes a requirement specification receiving unit 141, a configuration plan generation unit 142, a configuration plan evaluation unit 143, an application rule level generation unit 144, an application rule change unit 145, and a configuration plan output unit 146. Yes.

  The product configuration design apparatus performs processing of the entire flowchart of the configuration design apparatus shown in FIG. 5 by linking these units.

  In step 201, the required specification receiving unit 141 performs the required specification items of the input specification and the target specification requested from the remote input / output device 180 or the input / output device 190 via the communication network 181 and the communication device 170. The required specification value is received and stored in the required specification storage unit 123.

  In step 202, the configuration plan generation unit 142 determines a product configuration plan using the configuration determination rule stored in the configuration determination rule storage unit based on the value of the required specification received in step 201. As the configuration determination rule to be used, a rule satisfying the “rule level” is extracted and applied. At the time of generating the first configuration proposal, the rule level is applied as “0”. In the examples of the configuration determination rules No. 301, 302, and 303 in FIG. 2, the rule in the upper column of the rule level “0” is applied.

  FIG. 6 shows the extracted level 0 rules. Specifically, in the method determination of rule No. 301 with respect to the required specifications of FIG. 4, since level 0 is applied and the input BOD is 300 or more, the processing method determines coagulation sedimentation. Furthermore, since the processing method is coagulation sedimentation and level 0, the pump output 10 kW is determined as the equipment specification determination. Such processing is repeated, and the processing time 10h, the pump type P10, the pump price 800, and the other construction price 10000 are determined. FIG. 7 shows the determined configuration plan 1.

  In step 203, the configuration plan evaluation unit 143 calculates the performance, cost, and the like of the configuration plan generated by the configuration plan generation unit 142, and calculates an evaluation value. A known simulator is used to calculate the performance of the configuration plan. In the example of FIG. 7, the output BOD of the configuration plan 1 is calculated as 200, the processing time is 10 h as it is, and the price is 10,800, which is the sum of the pump price 800 and the other construction price 10,000.

  In step 204, the configuration plan evaluation unit 143 determines whether the target specification value of the generated configuration plan has been achieved. In the example of FIG. 7, the output BOD is 200 with respect to the required specification of 100 or less, and is not achieved. The achievement status of the target specification is calculated as a ratio, and it is calculated that 100% is not achieved.

  In step 205, the application rule level generation unit 144 determines whether or not the evaluation value calculated by the configuration plan evaluation unit 143 satisfies the target specification of the required specification, and if the target specification is not achieved, the achievement is achieved. Based on the situation, the change contents of the rule to be applied are extracted from the change methods stored in the change method storage unit 122.

  Specifically, in the example of FIG. 3, No. 401, 402, and 403 apply when the required specification achievement status of the output BOD is confirmed. Therefore, a combination of three rule changes is generated.

  For example, when the “output BOD” of the configuration proposal is “not reached 30% or more”, the change method data No. 401 is adopted, and the applied rule level of the rule group “equipment specification determination” is set to “+1”. Further, a combination of rules to be applied is generated based on the applied rule level. For example, when the above-mentioned “equipment specification determination” rule is “+1”, the rule level to be applied is changed to “1”. Therefore, from the configuration determination rule of FIG. The Therefore, in No. 402 of FIG. 3, the rule of two lines of rule level “0” and level “1” is applied. Therefore, combinations of these two lines and other rule levels occur. Specifically, the combination “No. 601” and the “equipment specification determination” level “1”, which are combinations of the “equipment specification determination” level “0” and the other rule level “0” as shown in FIG. It shows that two combinations of rule levels of the combination No. 602 are generated.

  Further, for the method specification determination, the applied rule level is +2 in FIG. 3 No. 402, so the method specification determination is applied up to the maximum level 2. Therefore, the system specification determination level 0, level 1, and level 2 are applied. However, since there is no level 1 in the method specification determination in the rules registered in FIG. 2, level 1 is omitted. Similarly, in the method determination, the maximum rule level to which No. 403 of FIG. 4 is applied is 3, and levels 0 to 3 can be applied, but levels 1 and 2 are not included in the rule of FIG. Omitted.

  Further, the total value of the rule level is calculated for each rule combination, and when all the combinations are enumerated, the level total value is calculated and held as “level total”. As a result, combination data of application rules for changing the configuration determination rule is as shown in FIG.

  In step 206, the application rule changing unit 145 starts from the rule level combination set by the application rule level generation unit 144 in step 205 in order from the rule combination having the lowest “level total” value, to the configuration determination rule storage unit 121. The configuration determination rule to be applied is extracted from the above and passed to the configuration plan generation unit 142 to be used for configuration plan generation. Specifically, the configuration determination rule of No. 601 with the low “level total” is extracted from the combination of the applied rule levels No. 601 and No. 602 in the example of FIG. . In the level combination No. 601, the rule of the rule level “0” in the configuration determination rule in FIG. 3 is extracted, and FIG. 6 is obtained. Next, a rule is also extracted for No. 602 having a level total “1”. At that time, the rule level “1” is extracted only for determining the No. 302 device specification, and the level “0” is extracted otherwise, as shown in FIG. Similarly, combinations of configuration determination rules of combinations Nos. 603 to 608 are generated.

  Returning again to step 202, the configuration plan generation unit 142 generates a configuration plan to which the configuration determination rule generated in step 206 is applied, evaluates each configuration plan in step 203, and satisfies all the evaluations in step 204. If a configuration plan is found, the process proceeds to step 208. If it is found in step 205 that a new rule level combination cannot be generated in step 205, the process is interrupted and the process proceeds to step 208.

  Finally, in step 208, the configuration plan output unit 146 receives the required specifications, the processing method and device configuration as the configuration plan generated by the configuration plan generation unit 142, the evaluation value of the configuration plan calculated by the configuration plan evaluation unit 143, Outputs the required specification achievement status of the evaluation value of the configuration plan.

  Specifically, as shown in FIG. 11, the required specifications, the achievement status of the required specifications, and the application rule level combination Nos. The processing method and the device configuration that are the configuration plan are displayed. On the horizontal axis, the required specification values and the specification values and evaluation values of each configuration plan are displayed side by side. This display may be rearranged according to required specification values and evaluation values. In addition, in the configuration plan, the achievement / unachieved column may be highlighted in the achievement status of the required specification. With this output, the user confirms the configuration plan, and if there is no problem, the user performs estimation and design based on the configuration plan.

  According to the configuration design apparatus described above, a feasible configuration plan corresponding to the required specification can be generated in a short time, and the estimation and design period can be shortened.
