Description

  The present invention relates to a technology that supports evaluation of basic units related to product manufacture and process design.

  In LCA (Life Cycle Assessment), a common basic unit created by a predetermined organization is statistically calculated based on a huge amount of data of the entire industry. In addition, since raw materials, manufacturing methods, and the like are improved as technology advances, the basic unit needs to be updated as needed. However, the common basic unit cannot be updated so frequently because the original data is enormous. Therefore, when a long time has passed since the common basic unit was updated, or when the company does not use industry standard materials or manufacturing methods, the environmental load is calculated using the common basic unit. Depending on the object and the object, the calculated environmental load value may deviate from the actual environmental load value in the company.

  Therefore, each company may independently calculate the basic unit within the range that can be investigated. For example, the following Patent Document 1 discloses a method for calculating a basic unit.

JP-A-8-235245

  By the way, when the environmental load is calculated by creating a basic unit uniquely using the conventional technology, the calculated environmental load value may be different from the environmental load value calculated using the common basic unit. In this case, if the environmental load value calculated based on the original basic unit is more accurate than the environmental load value calculated based on the common basic unit, it can be said that it represents the actual environmental load. In this evaluation, it is possible to calculate the value of the environmental load with higher accuracy by using that.

  On the other hand, if the environmental load value calculated based on the original basic unit is less accurate than the environmental load value calculated based on the common basic unit, the deviation from the actual environmental load value will be larger. It is necessary to review the calculation method of original unit consumption. If there is not much difference between the environmental load value calculated by the original basic unit and the environmental load value calculated by the common basic unit, the two will not change much in terms of accuracy difference from the actual environmental load. It will be.

  Therefore, the environmental load value calculated based on the original basic unit is more accurate or low, and the greater the difference from the environmental load value calculated based on the common basic unit, the more the replacement or calculation method is changed. It can be said that there is a high need for review.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to preferentially notify a unique basic unit having a large degree of deviation from a common basic unit.

  In order to solve the above problems, in the present invention, for each unique basic unit to be evaluated, a basic unit ratio indicating the degree to which the original basic unit to be evaluated deviates from the standard basic unit, The identification information of the basic unit to be evaluated is notified in descending order of the basic unit ratio.

For example, a basic unit evaluation support device that supports the evaluation of basic units,
A common basic unit information holding unit for holding a common basic unit ID for identifying each common basic unit and a value of the common basic unit in association with the date and time when the common basic unit was registered;
Unique basic unit information that stores the unique basic unit ID that identifies each of the unique basic units that are independently calculated by the company and the value of the unique basic unit in association with the date and time when the unique basic unit was calculated A holding part;
A correspondence information holding unit that holds a unique basic unit ID indicating the same basic unit as the basic unit indicated in the common basic unit ID in association with the common basic unit ID;
When the reference period and the evaluation period are designated by the user, the latest common basic unit within the reference period is extracted with reference to the common basic unit information holding unit for each common basic unit ID, and the original basic unit For each ID, the unique basic unit information holding unit is referred to extract the latest unique basic unit within the evaluation period, and the basic unit value corresponding to the unique basic unit ID is the corresponding common basic unit ID. A basic unit for obtaining a first basic unit ratio for each unique basic unit ID indicating the degree of deviation from the indicated common basic unit value and notifying the user of the unique basic unit ID in descending order of the first basic unit ratio A basic unit evaluation support apparatus comprising a ratio notification unit.

  Next, the unique basic unit creation unit 21 determines whether or not the execution unit 317 of the unique basic unit creation condition setting screen 31 has been selected by the user via the input device 11, thereby performing the unique basic unit creation process. It is determined whether execution has been instructed (S103). When the execution of the unique basic unit creation process is instructed (S103: Yes), the unique basic unit creation unit 21 executes the unique basic unit creation process (S200) to be described later. The process shown in step S100 is executed again.

  When execution of the unique basic unit creation process is not instructed (S103: No), the unique basic unit creation unit 21 selects the return button 316 on the unique basic unit creation condition setting screen 31 by the user via the input device 11. By determining whether or not the original basic unit creation processing has been canceled, it is determined (S104). When the original unit creation process is canceled (S104: Yes), the unit evaluation support device 20 executes the process shown in step S100 again. On the other hand, when the unique basic unit creation process has not been canceled (S104: No), the unique basic unit creation unit 21 executes the process shown in step S103 again.

  If the unique basic unit creation button 300 is not selected in step S101 (S101: No), the basic unit ratio notification unit 23 selects the basic unit comparison button 301 on the initial screen 30 by the user via the input device 11. It is determined whether or not (S105). When the basic unit comparison button 301 is not selected (S105: No), the unique basic unit creation unit 21 executes the process shown in step S101 again. When the basic unit comparison button 301 is selected (S105: Yes), the basic unit ratio notification unit 23 displays, for example, the basic unit comparison condition setting screen 32 shown in FIG. 12 on the output device 12 (S102).

  On the basic unit comparison condition setting screen 32, for example, as shown in FIG. 12, an area 3200 for inputting a factory ID, an area 3201 for inputting a product ID, an area 3202 for inputting a component ID, and an environmental aspect An area 3203 for selecting a base unit, an area 3204 for selecting a basic unit type as a reference for comparison, an area 3205 for inputting a reference period that is a calculation period of the basic unit used as a reference, and an evaluation target An area 3206 for inputting an evaluation period, which is a calculation period of the original basic unit, an area 3207 for selecting a type, an area 3208 for selecting a target stage, a return button 3209, and an execution button 3210 are displayed.

Is determined (S107). When execution of the basic unit ratio calculation process is instructed (S107: Yes), the basic unit ratio notification unit 23 executes a basic unit ratio calculation process (S300), which will be described later. The process shown in step S100 is executed again.

  When the execution of the basic unit ratio calculation processing is not instructed (S107: No), the basic unit ratio notification unit 23 selects the return button 3209 on the basic unit comparison condition setting screen 32 by the user via the input device 11. It is then determined whether or not the basic unit ratio calculation process has been canceled (S108). When the basic unit ratio calculation process is canceled (S108: Yes), the basic unit evaluation support apparatus 20 executes the process shown in step S100 again. On the other hand, when the basic unit ratio calculation process is not canceled (S108: No), the basic unit ratio notification unit 23 executes the process shown in step S107 again.

  First, the unique basic unit creation unit 21 extracts a record including the factory ID, product ID, and part ID specified by the user on the unique basic unit creation condition setting screen 31 from the measurement information holding unit 25 (S201). The record including the environmental aspect ID corresponding to the environmental aspect designated by the user is extracted from the recorded records (S202), and the date of manufacture is included in the period for which the basic unit is calculated from the extracted records. Records are extracted (S203).

  Next, the unique basic unit creation unit 21 determines whether the basic unit calculation method designated by the user is “average” (S204). When the calculation method of the basic unit designated by the user is “average” (S204: Yes), the unique basic unit creation unit 21 classifies the records extracted in step S203 for each process ID, and for each process ID. Calculate the total environmental load and the total production quantity. Then, the unique basic unit creation unit 21 calculates the basic unit value of the unique basic unit for each process ID by dividing the total value of the environmental load by the total value of the production quantity for each process ID (S205). The process shown in S211 is executed.

  When the basic unit calculation method designated by the user is not “average” (S204: No), the unique basic unit creation unit 21 determines whether or not the basic unit calculation method designated by the user is “maximum”. Determination is made (S206). When the calculation method of the basic unit designated by the user is “maximum” (S206: Yes), the unique basic unit creation unit 21 divides the environmental load by the production quantity for each record extracted in step S203, and the temporary basic unit. A unit value is calculated (S207). Then, the unique basic unit creation unit 21 classifies the records extracted in step S203 for each process ID, and sets the maximum value of the temporary basic unit calculated in step S207 for each process ID as the unique basic unit for each process ID. The basic unit value is calculated (S208), and the process shown in step S211 is executed.

  When the basic unit calculation method designated by the user is not “maximum” (S206: No), that is, when the basic unit calculation method designated by the user is “latest”, the unique basic unit creation unit 21 In the record extracted in step S203, the record with the latest manufacturing date is extracted for each process ID (S209), and the basic unit value is calculated by dividing the environmental load by the production quantity for the extracted record for each process ID (S210). ).

  Next, the unique basic unit creation unit 21 extracts the basic unit ID from the basic unit information holding unit 22 for each process ID, and associates the calculated basic unit value and the calculated date and time with the extracted basic unit ID. Stored in the unit information holding unit 26 (S211), for example, the calculation result screen 33 showing the calculation result of the basic unit value shown in FIG. 14 is displayed on the output device 12 (S212). In the example of the calculation result screen 33 shown in FIG. 14, the basic unit value calculation condition designated by the user is displayed in the area 330, and the environmental aspect ID and the basic unit are calculated for each basic unit ID as the basic unit value calculation result. The value and the unit of the basic unit value are displayed in the area 331.

  Next, the unique basic unit creation unit 21 determines whether or not the user has instructed to output the calculation result by operating the input device 11 and selecting the output button 333 shown in FIG. 14 (S213). ). When the output of the calculation result is instructed by the user (S213: Yes), the unique basic unit creation unit 21 outputs the calculation result in the area 331 in FIG. 14 to another computer or the like via the printer or the communication line 13. In step S214, the basic unit evaluation support apparatus 20 ends the operation shown in the flowchart.

  On the other hand, when the output of the calculation result is not instructed by the user (S213: No), the unique basic unit creation unit 21 operates the input device 11 to select the return button 332 shown in FIG. Thus, it is determined whether or not the display end of the calculation result is instructed (S215). If the user has not instructed the display end of the calculation result (S215: No), the unique basic unit creation unit 21 executes the process shown in step S213 again. When the user gives an instruction to end the display of the calculation result (S215: Yes), the basic unit evaluation support device 20 ends the operation shown in this flowchart.

  Next, the basic unit ratio calculation process (S300) will be described with reference to FIG. 15 and FIG. 15 and 16 are flowcharts showing an example of the basic unit ratio calculation process (S300).

  First, the basic unit ratio notifying unit 23 extracts a record including the factory ID, product ID, and component ID specified by the user on the basic unit comparison condition setting screen 32 from the basic unit information holding unit 22 (S301), From the recorded records, a record including the type and stage designated by the user is further extracted (S302).

  Next, the basic unit ratio notifying unit 23 determines whether or not the common basic unit is designated as a reference by the user (S303). When the common basic unit is designated as the reference (S303: Yes), the basic unit ratio notifying unit 23 extracts a record including the environmental aspect ID of the environmental aspect designated by the user from the common basic unit information holding unit 27 ( S304), the process shown in step S306 is executed.

  On the other hand, when the common basic unit is not specified as the reference (S303: No), that is, when the past unique basic unit is specified as the reference, the basic unit ratio notification unit 23 sets the environmental aspect of the specified environmental aspect. The record including the ID is extracted from the unique basic unit information holding unit 26 (S305). Then, the basic unit ratio notifying unit 23 calculates, for each basic unit ID, the basic unit value of the record that is the registration date within the reference period designated by the user and includes the latest registration date from the extracted records. Then, it is extracted as a reference basic unit value (S306).

  Next, the basic unit ratio notifying unit 23 extracts a record including the environmental side ID of the environmental side designated by the user from the unique basic unit information holding unit 26 (S307), and extracts the record for each basic unit ID. The basic unit value of the record that is the registration date within the evaluation period designated by the user and includes the latest registration date is extracted as the evaluation basic unit value (S308).

  Next, the basic unit ratio notifying unit 23 selects one unselected reference basic unit value from the reference basic unit values extracted in step S306 (S309), and the common basic unit is designated as a reference by the user. It is determined whether or not (S310). When the common basic unit is designated as the reference (S310: Yes), the basic unit ratio notifying unit 23 refers to the correspondence table holding unit 24 and corresponds to the common basic unit selected in step S309. It is determined whether or not there is a unique basic unit (S311).

  When there is no corresponding unique basic unit (S311: No), the basic unit ratio notifying unit 23 executes the process shown in step S314. When there is a corresponding unique basic unit (S311: Yes), the basic unit ratio notifying unit 23 refers to the correspondence table holding unit 24, and the unique unit corresponding to the common basic unit that is the reference basic unit selected in step S309. The basic unit ID of the basic unit is extracted. Then, the basic unit ratio notifying unit 23 extracts the evaluation basic unit value corresponding to the extracted basic unit ID from the evaluation basic unit values extracted in step S308, and in step S309, the extracted evaluation basic unit value. The basic unit ratio is calculated using, for example, the following calculation formula (1) using the selected reference basic unit value, which is the common basic unit value (S312), and the process shown in step S314 is executed.

  In step S310, when the common basic unit is not specified as the reference (S310: No), that is, when the past unique basic unit is specified as the reference, the basic unit ratio notification unit 23 extracts in step S308. From the evaluation basic unit values, an evaluation basic unit value having the same basic unit ID as the past original basic unit, which is the reference basic unit selected in step S309, is extracted, and the extracted evaluation basic unit value and selected in step S309 The basic unit ratio is calculated using, for example, the above-described calculation formula (1) using the past unique basic unit value which is the reference basic unit value (S313).

  Next, the basic unit ratio notifying unit 23 determines whether all the reference basic unit values extracted in step S306 have been selected (S314). If all the reference basic unit values extracted in step S306 are not selected (S314: No), the basic unit ratio notification unit 23 executes the process shown in step S309 again. On the other hand, when all the reference basic unit values extracted in step S306 are selected (S314: Yes), the basic unit ratio notifying unit 23 outputs a comparison result screen 34 showing the basic unit comparison results as shown in FIG. The information is displayed on the device 12 (S315).

  In the example of the comparison result screen 34 shown in FIG. 17, the basic unit ratio calculation conditions designated by the user are displayed in the area 340, and the ranking, the basic unit ratio value, and the basic basic unit ratio are calculated as the basic unit ratio calculation result. , The evaluation basic unit ratio value, and the basic unit ID of the original basic unit to be evaluated are displayed in the region 341, and a graph indicating the distribution of the basic unit ratio is displayed in the region 342.

  Next, the basic unit ratio notifying unit 23 determines whether or not the user has instructed to output the calculation result by operating the input device 11 and selecting the output button 344 shown in FIG. 17 (S316). ). When the output of the calculation result is instructed by the user (S316: Yes), the basic unit ratio notifying unit 23 displays the calculation result in the area 341 and the graph in the area 342 in FIG. 17 via the printer or the communication line 13. The data is output to another computer or the like (S317), and the basic unit evaluation support apparatus 20 ends the operation shown in this flowchart.

  On the other hand, when the output of the calculation result is not instructed by the user (S316: No), the basic unit ratio notification unit 23 operates the input device 11 to select the return button 343 shown in FIG.
