Summary of Invention

[0003] A management device according to one aspect of the present invention may be a management device that manages greenhouse gas (GHG) emissions discharged in association with the manufacture of a target product manufactured through a plurality of manufacturing steps including a first manufacturing step by a first manufacturer. The management device may include a request receiving unit that receives, for the first manufacturer, a request for input of unit process type GHG emission information for specifying GHG emissions discharged in the first manufacturing step, or receives a request for input of process total type GHG emission information for specifying GHG emissions discharged before the first manufacturing step. The management device may include an input requesting unit that requests the first manufacturer to input the unit process type GHG emission information of the target product for the first manufacturing step, or input the process total type GHG emission information of the target product for the period before the first manufacturing step, in accordance with the reception result from the request receiving unit. The management device receives, from the first manufacturer, the input of the unit process type GHG emission information of the target product for the first manufacturing step, or the input of the process total type GHG emission information of the target product for the period before the first manufacturing step, and may include an input receiving unit that registers the unit process type GHG emission information of the target product for the first manufacturing step or the process total type GHG emission information of the target product for the period before the first manufacturing step in a database.

[0004] In the management device, the plurality of manufacturing processes may include a second manufacturing process by a second manufacturer prior to the first manufacturing process. When the request receiving unit receives a request for input of unit process type GHG emission information for the target product for the first manufacturing process, it may further receive a request from the second manufacturer for input of unit process type GHG emission information for the target product for the second manufacturing process, or a request for input of process aggregate type GHG emission information for the target product for processes prior to the second manufacturing process. Depending on the reception result at the request receiving unit, the input request unit may request the second manufacturer to input unit process type GHG emission information for the target product for the second manufacturing process, or to input process aggregate type GHG emission information for the target product for processes prior to the second manufacturing process. The input receiving unit may receive from the second manufacturer the input of unit process type GHG emission information for the target product for the second manufacturing process, or process aggregate type GHG emission information for the target product prior to the second manufacturing process, and may further register the GHG emission information for the target product for the second manufacturing process or the process aggregate type GHG emission information for the target product prior to the second manufacturing process in the database.

[0005] Any of the management devices may further include a request receiving unit that receives requests from the first manufacturer for input of process-aggregate GHG emission information for the target product for the period prior to the first manufacturing process, and for input of unit-process type GHG emission information for the target product for the period prior to the first manufacturing process. The plurality of manufacturing processes may include a second manufacturing process by a second manufacturer prior to the first manufacturing process. When the request receiving unit receives a request from the request receiving unit for input of unit-process type GHG emission information for the target product for the first manufacturing process, the input request unit may request the first manufacturer to input the unit-process type GHG emission information for the target product for the first manufacturing process, and may also request the second manufacturer to input process-aggregate GHG emission information for the target product for the period prior to the second manufacturing process. The input receiving unit may receive input of process-aggregate GHG emission information for the target product for the period prior to the second manufacturing process from the second manufacturer and further register the process-aggregate GHG emission information for the target product for the period prior to the second manufacturing process in the database.

[0006] In any of the management devices, the plurality of manufacturing processes may include a third manufacturing process by a third manufacturer prior to the second manufacturing process. The inquiry receiving unit may accept an inquiry from the second manufacturer for input of process-aggregate GHG emission information for the target product prior to the second manufacturing process, and for input of unit-process type GHG emission information for the target product for the second manufacturing process. The input requesting unit may, when the inquiry receiving unit accepts an inquiry for input of unit-process type GHG emission information for the target product for the second manufacturing process, request the second manufacturer to input unit-process type GHG emission information for the target product for the second manufacturing process, and also request the third manufacturer to input process-aggregate GHG emission information for the target product prior to the third manufacturing process. The input receiving unit may receive the input of process-aggregate GHG emission information for the target product prior to the third manufacturing process from the third manufacturer and further register the process-aggregate GHG emission information for the target product prior to the third manufacturing process in the database.

[0007] In any of the above-mentioned control devices, the first manufacturer may be a primary contractor, the second manufacturer may be a secondary contractor, and the third manufacturer may be a tertiary contractor.

[0008] In any of the control devices, the amount of GHG emissions from each of the multiple manufacturing processes may be calculated according to the primary emission factor specific to the target product, or a common secondary emission factor corresponding to the type of target product. The GHG emission information may include information indicating the proportion of the emission factors used to calculate the GHG emissions from each of the multiple manufacturing processes that are calculated by at least one of the primary emission factor and the secondary emission factor.

[0009] A management method according to one aspect of the present invention may be a management method for managing greenhouse gas (GHG) emissions associated with the manufacture of a target product produced by a first manufacturer through a plurality of manufacturing processes, including a first manufacturing process. The management method may include a step in which a request receiving unit receives a request from the first manufacturer to input unit process type GHG emission information for identifying GHG emissions emitted in the first manufacturing process, or a request to input process aggregate type GHG emission information for identifying GHG emissions emitted before the first manufacturing process. The management method may also include a step in which an input request unit requests the first manufacturer to input unit process type GHG emission information for the target product for the first manufacturing process, or process aggregate type GHG emission information for the target product for the process before the first manufacturing process, depending on the reception result at the request receiving unit. The management method may include a step in which the input receiving unit receives from the first manufacturer the input of unit process type GHG emission information for the target product for the first manufacturing process, or process aggregate type GHG emission information for the target product for processes prior to the first manufacturing process, and registers the unit process type GHG emission information for the target product for the first manufacturing process or the process aggregate type GHG emission information for the target product for processes prior to the first manufacturing process in a database.

[0010] The program according to one aspect of the present invention may be a program for causing a computer to function as a management device for managing greenhouse gas (GHG) emissions associated with the manufacture of a target product produced by a first manufacturer through a plurality of manufacturing processes, including a first manufacturing process. The program may cause the computer to function as a request receiving unit that accepts requests from the first manufacturer for input of unit process type GHG emission information to identify GHG emissions emitted in the first manufacturing process, or for input of process aggregate type GHG emission information to identify GHG emissions emitted before the first manufacturing process. Depending on the reception result at the request receiving unit, the program may cause the computer to function as an input request unit that requests the first manufacturer for input of unit process type GHG emission information for the target product for the first manufacturing process, or for input of process aggregate type GHG emission information for the target product for the process before the first manufacturing process. The program may configure the computer to function as an input receiving unit that receives input from the first manufacturer of unit process type GHG emission information for the target product for the first manufacturing process, or process aggregate type GHG emission information for the target product prior to the first manufacturing process, and registers the unit process type GHG emission information for the target product for the first manufacturing process or the process aggregate type GHG emission information for the target product prior to the first manufacturing process in a database.

[0011] It should be noted that the above summary of the invention does not enumerate all of its features. Furthermore, subcombinations of these features may also constitute an invention. [Brief explanation of the drawing]

[0012] [Figure 1] This diagram shows an example of the inter-company transaction structure in automobile manufacturing. [Figure 2] This figure shows an example of the overall configuration of a management system for managing GHG emissions according to this embodiment. [Figure 3]This figure shows an example of a functional block of a management device. [Figure 4] This flowchart shows an example of a procedure for specifying the input format of GHG emissions information required from each contractor. [Figure 5] This flowchart shows an example of the processing procedure when a contractor, having received a request to input process-aggregated GHG emission information, asks for input of unit-process GHG emission information instead. [Figure 6] This figure shows an example of a hardware configuration. [Modes for carrying out the invention]

[0013] The present invention will be described below through embodiments of the invention, but these embodiments are not intended to limit the invention as defined in the claims. Furthermore, not all combinations of features described in the embodiments are necessarily essential to the solution of the invention.

[0014] In recent years, there has been a growing desire to accurately derive greenhouse gas emissions (GHG emissions) for each stage of product manufacturing, thereby determining the total GHG emissions associated with product production. Here, the stages include the collection, transportation and storage, processing, and assembly of parts of raw materials or components.

[0015] Therefore, the management device 100 according to this embodiment reduces the burden of managing the GHG emissions of the product while promoting the derivation of GHG emissions for each manufacturing process.

[0016] Products are manufactured through multiple processes. These processes may be carried out by different organizations.

[0017] For example, in the manufacture of automobiles, there are multiple parts manufacturers that supply parts to the finished vehicle manufacturer. Figure 1 shows an example of the inter-firm transaction structure in automobile manufacturing. The inter-firm transaction structure in automobile manufacturing is a so-called pyramid structure. Tier 0 represents the finished product manufacturer (Company A). Tier 1 represents the primary contractors (Companies B1 and B2) that directly supply parts to the finished product manufacturer. Tier 2 represents the secondary contractors (Companies C1, C2, C3, and C4) that directly supply parts or materials to the primary contractors. Tier 3 represents the tertiary contractors (Companies D1, D2, D3, and D4) that directly supply parts or materials to the secondary contractors. Note that Figure 1 shows tiers 0 through 3, but depending on the inter-firm transaction structure, there may be tiers 4 and above.

[0018] Manufacturers of finished products want to be provided with GHG emissions data for each stage of the manufacturing process. However, manufacturers of finished products may not be able to identify Tier 2 or lower contractors with whom they do not have direct business relationships. In such cases, it is difficult for manufacturers of finished products to determine the GHG emissions for each stage of the manufacturing process.

[0019] Figure 2 shows an example of the overall configuration of the management system 10 for managing GHG emissions according to this embodiment. The management system 10 comprises a management device 100 and a plurality of input terminals 200. The management device 100 communicates with the plurality of input terminals 200 via a network 50. The management device 100 is a device that can be operated by a person in charge at a Tier 0 finished product manufacturing company. The input terminals 200 are devices that can be operated by a person in charge at each of the Tier 1 to 3 contractor companies.

[0020] The management device 100 collects and manages GHG emission information related to the target products provided from each input terminal 200. In this embodiment, an example is described in which the management system 10 comprises one management device 100. However, the management system 100 may comprise, for example, a management device 100 for each different tier of the hierarchy or for each contractor. Multiple management devices 100 may exchange GHG emission information, as described later.

[0021] Figure 3 shows an example of functional blocks of a management apparatus 100. The management apparatus 100 includes a control unit 110, a communication unit 120, and a database 130. The management apparatus 100 manages GHG emission amount information for specifying the GHG emission amount discharged along with the manufacture of a target product. The target product, which is an object for deriving the GHG emission amount, is manufactured through a plurality of manufacturing processes. The target product is, for example, an automobile. The plurality of manufacturing processes include a first manufacturing process by a tier 1 primary contractor, a second manufacturing process by a tier 2 secondary contractor, and a third manufacturing process by a tier 3 tertiary contractor. The tier 1 primary contractor is an example of a first manufacturer. The tier 2 secondary contractor is an example of a second manufacturer. The tier 3 tertiary contractor is an example of a third manufacturer.

[0022] The control unit 110 may be configured by a microprocessor such as a CPU or MPU, a microcontroller such as an MCU, or the like. The communication unit 120 manages communication between respective components in the management apparatus 100. In addition, the communication unit 120 communicates with an external computer such as an input terminal 200 via a network 50 such as the Internet. The database 130 stores the GHG emission amounts related to the target product provided from each of the input terminals 200.

[0023] The control unit 110 has a request receiving unit 112, an input requesting unit 114, an input receiving unit 116, and a consultation receiving unit 118. The request receiving unit 112 receives a request for input of unit process type GHG emission amount information for specifying the GHG emission amount discharged in the first manufacturing process of the tier 1 primary contractor from the tier 1 primary contractor, or receives a request for input of process summation type GHG emission amount information for specifying the GHG emission amount discharged before the first manufacturing process.

[0024] Unit-process type GHG emission information is information used to identify so-called gate-to-gate (G2G) type GHG emissions. Unit-process type GHG emission information may include gate-to-gate emission factors. Gate-to-gate emission factors indicate the GHG emissions per specific unit (e.g., per product, per unit weight of product) emitted in a specific manufacturing process.

[0025] The emission intensity includes a primary emission intensity, which is determined based on measured values ​​of GHG emissions emitted during the manufacturing of the target product, and a secondary emission intensity, which is determined based on industry standards, medians, averages, etc., for each country or region for the type of product to which the target product belongs. The primary emission intensity is more accurate than the secondary emission intensity. Therefore, it is preferable that the emission intensity for each manufacturing process be the primary emission intensity. The higher the proportion of primary emission intensity among all emission intensity in each manufacturing process used for the target product, the higher the accuracy of the GHG emissions for the target product. Therefore, the GHG emission information provided by each contractor may include information indicating whether the emission intensity is primary or secondary. In addition, the GHG emissions for each manufacturing process may be calculated according to either the primary or secondary emission intensity. In this case, the GHG emission information may include information indicating the proportion of the emission intensity used to calculate the GHG emissions for each manufacturing process that is calculated by at least one of the primary or secondary emission intensity. GHG emission information may include information (PDS: Primary Data Score) indicating the proportion of the emission intensity used to calculate GHG emissions for each manufacturing process that is calculated using the primary emission intensity.

[0026] Process-aggregated GHG emission information is information used to identify so-called cradle-to-gate (C2G) type GHG emissions. Cradle-to-gate GHG emission information is information used to identify GHG emissions emitted before the target manufacturing process. In other words, cradle-to-gate GHG emission information is information used to identify GHG emissions emitted up to the target manufacturing process. Cradle-to-gate GHG emission information is information used to identify the total GHG emissions emitted in all manufacturing processes prior to the target manufacturing process. Cradle-to-gate GHG emission information may include cradle-to-gate emission intensity. Cradle-to-gate emission intensity indicates the GHG emissions per specific unit emitted before the target manufacturing process.

[0027] The input request unit 114 requests the Tier 1 primary contractor to input either unit process type GHG emission information for the target product for the first manufacturing process, or process aggregate type GHG emission information for the target product for processes prior to the first manufacturing process, depending on the result of the request reception unit 112.

[0028] The input receiving unit 116 receives input from Tier 1 primary contractors, either unit process type GHG emission information for the target product for the first manufacturing process, or process aggregate type GHG emission information for the target product prior to the first manufacturing process. The unit process type GHG emission information for the target product for the first manufacturing process or process aggregate type GHG emission information for the target product prior to the first manufacturing process is then registered in the database 130. For example, unit process type GHG emission information may include GHG emission information for direct emissions (Scope 1) such as the use of fuel by the Tier 1 primary contractor and indirect emissions (Scope 2) such as the use of electricity purchased from other companies, which are attributable to the manufacturing of the target product by the Tier 1 primary contractor. Process aggregate type GHG emission information may include, in addition to the above GHG emission information from the Tier 1 primary contractor, various GHG emission information from upstream processes attributable to the manufacturing of the target product.

[0029] When the request receiving unit 112 receives a request for input of unit process type GHG emission information for the target product for the first manufacturing process, it may further receive a request from the Tier 2 secondary contractor for input of unit process type GHG emission information for the target product for the second manufacturing process, or a request for input of process aggregate type GHG emission information for the target product for processes prior to the second manufacturing process.

[0030] The input request unit 114 may request the Tier 2 secondary contractor to input unit process type GHG emission information for the target product for the second manufacturing process, or process aggregate type GHG emission information for the target product before the second manufacturing process, depending on the reception result at the request reception unit 112. The input reception unit 116 receives the input of unit process type GHG emission information for the target product for the second manufacturing process, or process aggregate type GHG emission information for the target product before the second manufacturing process, from the Tier 2 secondary contractor, and may further register the GHG emission information for the target product for the second manufacturing process or the process aggregate type GHG emission information for the target product before the second manufacturing process in the database 130.

[0031] A contractor who receives a request to input process-aggregated GHG emission information may be able to provide unit-process type GHG emission information. Therefore, when the inquiry reception unit 118 receives a request from a Tier 1 primary contractor to input process-aggregated GHG emission information for the target product up to the first manufacturing process, it accepts an inquiry for input of unit-process type GHG emission information for the target product up to the first manufacturing process. In this embodiment, the inquiry for input of unit-process type GHG emission information is accepted, but it is also possible to accept input of unit-process type GHG emission information and process-aggregated GHG emission information from the second manufacturing process onward without making an inquiry. Furthermore, a Tier 1 primary contractor may make inquiries within their own organization (i.e., within Tier 1, not Tier 2) regarding the input of unit-process type GHG emission information and process-aggregated GHG emission information from the second manufacturing process onward.

[0032] If the inquiry reception unit 118 receives an inquiry regarding the input of unit process type GHG emission information for the target product for the first manufacturing process, the input request unit 114 may request the Tier 1 primary contractor to input the unit process type GHG emission information for the target product for the first manufacturing process, and the Tier 2 secondary contractor to input the process aggregate type GHG emission information for the target product for the second manufacturing process and earlier.

[0033] The input receiving unit 116 may receive process-aggregated GHG emission information for the target product prior to the second manufacturing process from a Tier 2 subcontractor, and may further register the process-aggregated GHG emission information for the target product prior to the second manufacturing process in the database 130.

[0034] When the inquiry reception unit 118 requests a Tier 2 subcontractor to input process-aggregated GHG emission information for the target product prior to the second manufacturing process, it may further accept inquiries for input of unit-process type GHG emission information for the target product for the second manufacturing process.

[0035] If the inquiry reception unit 118 receives an inquiry regarding the input of unit process type GHG emission information for the target product for the second manufacturing process, the input request unit 114 may request the Tier 2 secondary contractor to input the unit process type GHG emission information for the target product for the second manufacturing process, and the Tier 3 tertiary contractor to input the process aggregate type GHG emission information for the target product for the third manufacturing process and earlier.

[0036] The input receiving unit 116 may receive process-aggregated GHG emission information for the target product prior to the third manufacturing process from a Tier 3 third-tier subcontractor, and may further register the process-aggregated GHG emission information for the target product prior to the third manufacturing process in the database 130.

[0037] Figure 4 is a flowchart illustrating an example of the procedure for specifying the input format of GHG emission information required from each contractor.

[0038] The request receiving unit 112 accepts input formats for GHG emission information from Tier 1 primary contractors (S100). On the input screen, a representative of a Tier 0 finished product manufacturer may select whether to request the Tier 1 primary contractor to input unit process type GHG emission information to identify GHG emissions emitted in the Tier 1 primary contractor's first manufacturing process, or to request the input of process aggregate type GHG emission information to identify GHG emissions emitted before the first manufacturing process. If there are multiple Tier 1 primary contractors involved in the manufacturing of the target product, the request receiving unit 112 may accept input formats for GHG emission information separately from each primary contractor.

[0039] The input request unit 114 determines whether the input format for the Tier 1 primary contractor is of the unit process type (S102). If the input format for the Tier 1 primary contractor is of the process aggregate type, the input request unit 114 requests the Tier 1 primary contractor to input process aggregate type GHG emission information (S104). The input request unit 114 may request the Tier 1 primary contractor to input process aggregate type GHG emission information by sending a message via the communication unit 120 to the person in charge at the Tier 1 primary contractor, such as by email.

[0040] If the input format for the Tier 1 primary contractor is unit process type, the input request unit 114 requests the Tier 1 primary contractor to input unit process type GHG emission information (S106). Furthermore, the request reception unit 112 accepts the input format for the GHG emission information for the Tier 2 secondary contractor (S108). If there are multiple Tier 2 secondary contractors involved in the manufacturing of the target product, the request reception unit 112 may accept the input format for the GHG emission information separately from each of the secondary contractors.

[0041] The input request unit 114 determines whether the input format for the Tier 2 subcontractor is of the unit process type (S110). If the input format for the Tier 2 subcontractor is of the process aggregate type, the input request unit 114 requests the Tier 2 subcontractor to input process aggregate type GHG emission information (S112).

[0042] If the input format for the Tier 2 subcontractor is unit process type, the input request unit 114 requests the Tier 2 subcontractor to input unit process type GHG emission information (S114). Furthermore, the input request unit 114 requests the Tier 3 tertiary subcontractor to input unit process type GHG emission information (S116).

[0043] As described above, each contractor can be requested to input GHG emission information in either a unit process type or process aggregate type. The GHG emission information input by Tier 1 primary contractors or Tier 2 secondary contractors may be stored in database 130 for sharing with organizations other than Tier 0 or Tier 1 that requested the input. Furthermore, the GHG emission information obtained by Tier 0 from Tier 1 and below may be shared with Tier 1 and below.

[0044] Figure 5 is a flowchart illustrating an example of the processing procedure when a contractor, having received a request to input process-aggregated GHG emission information, inquires about inputting unit-process GHG emission information instead.

[0045] The inquiry reception unit 118 determines whether it has received an inquiry from a Tier 1 primary contractor regarding the input of unit process type GHG emission information (S200). If an inquiry has been received, the input request unit 114 requests the Tier 1 primary contractor to input the unit process type GHG emission information (S202). Furthermore, the input request unit 114 requests the Tier 2 secondary contractor to input process aggregate type GHG emission information (S204).

[0046] Furthermore, the inquiry reception unit 118 determines whether it has received an inquiry from a Tier 2 subcontractor regarding the input of unit process type GHG emission information (S206). If an inquiry has been received, the input request unit 114 requests the Tier 2 subcontractor to input the unit process type GHG emission information (S208). Furthermore, the input request unit 114 requests the Tier 3 tertiary subcontractor to input the unit process type GHG emission information (S210).

[0047] As described above, by accepting inquiries from contractors who have been asked to input process-aggregated GHG emission information, it is possible to further increase the proportion of unit-process type GHG emission information for the target products.

[0048] Figure 6 shows an example of a computer 1200 that may embody an aspect of this embodiment in whole or in part. A program installed on the computer 1200 can cause the computer 1200 to function as an operation associated with an apparatus according to an embodiment of the present invention, or as one or more "parts" of said apparatus. Alternatively, the program can cause the computer 1200 to execute said operation or said one or more "parts." The program can cause the computer 1200 to execute a process or a stage of said process according to an embodiment of the present invention. Such a program can cause the computer 1200 to execute a specific operation associated with some or all of the blocks in the flowcharts and block diagrams described herein. It may be executed by CPU1212.

[0049] The computer 1200 according to this embodiment includes a CPU 1212 and RAM 1214, which are interconnected by a host controller 1210. The computer 1200 also includes a communication interface 1222 and input / output units, which are connected to the host controller 1210 via an input / output controller 1220. The computer 1200 also includes a ROM 1230. The CPU 1212 operates according to programs stored in the ROM 1230 and RAM 1214, thereby controlling each unit.

[0050] The communication interface 1222 communicates with other electronic devices via a network. A hard disk drive may store programs and data used by the CPU 1212 in the computer 1200. The ROM 1230 stores boot programs and / or programs that depend on the computer 1200's hardware, such as a boot program executed by the computer 1200 upon activation. Programs are provided via computer-readable recording media such as a CR-ROM, USB memory, or IC card, or via a network. Programs are installed in RAM 1214, which is also an example of a computer-readable recording media, or in ROM 1230, and executed by the CPU 1212. The information processing described within these programs is read by the computer 1200, resulting in coordination between the programs and the various types of hardware resources described above. An apparatus or method may be configured to implement information operations or processing in accordance with the use of the computer 1200.

[0051] For example, when communication is performed between a computer 1200 and an external device, the CPU 1212 may execute a communication program loaded into RAM 1214 and, based on the processing described in the communication program, instruct the communication interface 1222 to perform communication processing. Under the control of the CPU 1212, the communication interface 1222 reads the transmission data stored in the transmission buffer area provided in RAM 1214 or a recording medium such as a USB memory, sends the read transmission data to the network, or writes the received data received from the network to a receive buffer area or the like provided on the recording medium.

[0052] Furthermore, the CPU 1212 may read all or necessary parts of a file or database stored on an external storage medium such as a USB memory stick into the RAM 1214, and perform various types of processing on the data in the RAM 1214. The CPU 1212 may then write the processed data back to the external storage medium.

[0053] Various types of information, such as various types of programs, data, tables, and databases, may be stored on the recording medium and subjected to information processing. The CPU 1212 may perform various types of processing on the data read from RAM 1214, including various types of operations, information processing, conditional judgments, conditional branching, unconditional branching, information retrieval / replacement, etc., as described throughout this disclosure and specified by the program instruction sequence, and write the results back to RAM 1214. The CPU 1212 may also retrieve information in files, databases, etc., within the recording medium. For example, if multiple entries are stored in the recording medium, each having an attribute value of a first attribute associated with an attribute value of a second attribute, the CPU 1212 may search among the multiple entries for an entry that matches the condition for which the attribute value of the first attribute is specified, read the attribute value of the second attribute stored in that entry, and thereby obtain the attribute value of the second attribute associated with the first attribute that satisfies a predetermined condition.

[0054] The program or software module described above may be stored on or near computer 1200 on a computer-readable storage medium. Alternatively, a recording medium such as a hard disk or RAM provided within a server system connected to a dedicated communication network or the Internet can be used as a computer-readable storage medium, thereby providing the program to computer 1200 via the network.

[0055] Computer-readable media may include any tangible device capable of storing instructions that can be executed by a suitable device. As a result, computer-readable media having instructions stored therein will comprise a product containing instructions that can be executed to create means for performing operations specified in a flowchart or block diagram. Examples of computer-readable media may include electronic storage media, magnetic storage media, optical storage media, electromagnetic storage media, semiconductor storage media, etc. More specific examples of computer-readable media may include floppy disks (registered trademark), diskettes, hard disks, random access memory (RAM), read-only memory (ROM), erasable programmable read-only memory (EPROM or flash memory), electrically erasable programmable read-only memory (EEPROM (registered trademark)), static random access memory (SRAM), compact disk read-only memory (CD-ROM), digital versatile disk (DVD), Blu-ray (RTM) disk, memory stick, integrated circuit card, etc.

[0056] Computer-readable instructions may include either source code or object code written in any combination of one or more programming languages. Source code or object code may include conventional procedural programming languages. These conventional procedural programming languages ​​may include assembler instructions, instruction set architecture (ISA) instructions, machine instructions, machine-dependent instructions, microcode, firmware instructions, state setting data, or object-oriented programming languages ​​such as Smalltalk®, Java®, C++, etc., and the "C" programming language or similar programming languages. Computer-readable instructions may be provided locally or via a wide area network (WAN), such as a local area network (LAN) or the internet, to the processor or programmable circuit of a general-purpose computer, a special-purpose computer, or other programmable data processing device. The processor or programmable circuit may execute computer-readable instructions to create means for performing operations specified in a flowchart or block diagram. Examples of processors include computer processors, processing units, microprocessors, digital signal processors, controllers, microcontrollers, etc.

[0057] Although the present invention has been described above using embodiments, the technical scope of the present invention is not limited to the scope described in the above embodiments. It will be apparent to those skilled in the art that various modifications or improvements can be made to the above embodiments. It will be clear from the claims that such modified or improved forms may also be included in the technical scope of the present invention.

[0058] It should be noted that the execution order of operations, procedures, steps, and stages in the apparatus, systems, programs, and methods shown in the claims, specifications, and drawings is not explicitly stated as "before," "prior to," etc., and that these can be implemented in any order unless the output of a previous process is used in a later process.
