First Embodiment
The first embodiment will be described below with reference to the drawings. FIG. 1 is a diagram illustrating a system configuration of a material management system 100 according to the first embodiment.
[0009]
The material management system 100 according to the present embodiment includes a material management apparatus 200, a terminal apparatus 300, a terminal apparatus 400, a measurement device 500, and a measurement device 600.
[0010]
In the material management system 100 according to the present embodiment, the material management apparatus 200, the terminal apparatus 300, and the terminal apparatus 400 are connected with one another via a network such as the Internet. In the material management system 100, the measurement device 500 performs short-range wireless communication with the terminal apparatus 300 using any desired technology such as BLUETOOTH. The measurement device 600 performs short-range wireless communication with the terminal apparatus 400 using any desired technology such as BLUETOOTH.
[0011]
The material management system 100 according to the present embodiment manages quality information indicating the quality of a material of waste. In one example, the quality information of the material is referred to by a business operator handling waste, for example, in transactions of waste with another business operator. The quality information will be described in detail below.
[0012]
In the present disclosure, examples of business operators handling waste include a business operator acting as a provider who provides a waste material, and a business operator acting as a user who uses the waste material. For example, the business operator as the provider is a waste discharge operator, and the business operator as the user is a waste treatment operator. [0013]
The waste discharge operator is a business operator who sorts waste into different materials, and stores the materials. The waste treatment operator is a business operator who applies intermediate treatment or regeneration treatment to the materials.
[0014]
In the material management system 100 according to the present embodiment, the terminal apparatus 300 is, for example, a terminal apparatus used by the business operator as the provider, and the terminal apparatus 400 is, for example, a terminal apparatus used by the
business operator as the user. In the following description, the terminal apparatus 300 is referred to as the provider terminal 300, and the terminal apparatus 400 is referred to as the user terminal 400. Further, in the following description, the business operator as the provider who provides the materials of waste is referred to as a provider, and the business operator as the user who uses the materials of waste is referred to as a user. In the present embodiment, it is assumed that one type of waste material is traded; however, more than one type of waste material may be traded. Further, such waste material may be a resin.
[0015]
The business operator acting as the provider and the business operator acting as the user do not have to be distinguished from each other, such that one business operator may act as the provider or the user depending on the situation.
[0016]
The measurement device 500 and the measurement device 600 according to the present embodiment are each implemented by a hand-held (portable) spectroscope. The measurement device 500 measures a property of the material as a transaction subject, and outputs the resultant measurement data including a near-infrared light spectrum to the provider terminal 300. Similarly, the measurement device 600 measures a property of the material as the transaction subject, and outputs the resultant measurement data including a near-infrared light spectrum to the user terminal 400. [0017]
The provider terminal 300 according to the present embodiment transmits the measurement data output from the measurement device 500 to the material management apparatus 200. Specifically, the provider terminal 300 transmits, to the material management apparatus 200, the measurement data of the material to be provided to the user in transaction with the user, and stores the measurement data in the material management apparatus 200. The user terminal 400 acquires quality information of the material obtained through the transaction with the provider from the material management apparatus 200, and displays the acquired quality information. The user terminal 400 further transmits the measurement data of the material, which is acquired using the measurement device 600, to the material management apparatus 200. The material management apparatus 200 verifies the measurement data received from the user terminal 400, with the measurement data received from the provider terminal 300. [0018]
The material management apparatus 200 includes a quality information database (DB) 240, a measurement database (DB) 250, and a quality information manager 260. [0019]
The quality information database 240 stores, for each material to be traded, quality information indicating the quality of the material. The quality information is generated by the quality information manager 260. The quality information according to the present embodiment may be used as, for example, information for determining whether to issue a certification to prove that the material has a certain level of quality. The measurement
database 250 stores the measurement data received from the provider terminal 300. The measurement database 250 serves as a measurement data storage unit.
[0020]
The quality information manager 260 generates the quality information of the material using the measurement data received from the provider terminal 300, and stores the quality information in the quality information database 240. The quality information manager 260 outputs the quality information of the material, selected at the user terminal 400, to the user terminal 400. Further, in response to receiving the measurement data from the user terminal 400, the quality information manager 260 verifies the measurement data that is received with the measurement data that is received from the provider terminal 300 and stored in the quality information database 240, and outputs a result of the verification to the user terminal 400. [0021]
In the present embodiment, examples of output include transmitting information to an external apparatus, and displaying information on a display. The external apparatus is any apparatus connected to the material management apparatus 200, for example, via a network. The display may be a display included in the external apparatus or a display included in the material management apparatus 200.
[0022]
In the present embodiment, the quality information indicating the quality of the material as a transaction subject, is managed, for example, using a database. With the database, in the transaction of the material, a person in charge, who works at the business operator, does not have to go to a storage location of the material and manually check the quality of the material. Accordingly, the quality of the material can be easily checked.
[0023]
The material management apparatus 200 according to the present embodiment may be implemented by a cloud server on the Internet. Alternatively, the material management apparatus 200 may be implemented by a plurality of information processing apparatuses each being a server.
[0024]
In the embodiment described with reference to FIG. 1, the material management apparatus 200 includes the quality information database 240 and the quality information manager 260, but the present invention is not limited to this embodiment. Any one of the quality information database 240 and the measurement database 250 may be partly or entirely disposed at another apparatus that communicates with the material management apparatus 200. Further, the measurement database 250 may store part or entire information stored in the quality information database 240, such that the measurement database 250 may be used as the quality information database 240.
[0025]
In the material management system 100 according to the present embodiment, the number of each of the provider terminal 300 and the user terminal 400 is one, but the present invention is
not limited to this embodiment. The number of provider terminals 300 and the number of user terminals 400 may be changed according to the number of business operators that use a service provided by the material management system 100.
[0026]

Referring now to FIG. 4, the quality information database 240 according to the present embodiment is described below. FIG. 4 is a diagram illustrating a quality information database according to the first embodiment. The quality information database 240 according to the present embodiment serves as a quality information storage unit that stores quality information. The material management apparatus 200 manages the quality information database 240 for each of the business operators each operating as a provider. [0041]
The quality information database 240 includes, as information items, a business operator ID, a business operator name, a material name, a measurement date and time, a measurement location, a measurement target image, a measurement condition, impurity information, a material weight, a material producer or processor, a material production date or material processing date, a material production condition or material processing condition, and measurement data, for example. The items “business operator ID” and “material name” are associated with the other items.
[0042]
In the present embodiment, information associating the values of the item “business operator ID” and “material name”, and the values of the other items is referred to as quality information.
[0043]

The value of the item “business operator ID" is identification information for identifying a business operator as a provider in the material management apparatus 200. The value of the item "business operator name" indicates a name of the business operator identified with the business operator ID.
[0047]
In the example illustrated in FIG. 4 according to the present embodiment, it is assumed that the provider that provides the material is a business entity such as a company, but the present embodiment is not limited to this example. The business operator that provides the material may be an individual. In such cases, the values of the items "business operator ID" and "business operator name" are identification information for identifying the individual as the provider (providing source) providing the material and the name of such provider, respectively.
[0048]
The value of the item "material name" is the name of the material. The value of the item "material name" may be specified by analyzing the measurement data, for example. [0049]
The value of the item "measurement date and time" is the date and time when the measurement device 500 measured a property of the material. In other words, the value of the item "measurement date and time" indicates a date and time when the measurement device 500 acquired the measurement data.
[0050]
The value of the item "measurement location" is a location where the measurement device 500 measured the property of the material. Specifically, for example, the value of the item
"measurement location" may be information indicating the current location of the provider terminal 300 when the provider terminal 300 captured an image of the material.
[0051]
The value of the item "measurement target image" is a file name of image data representing an image of the material having been captured by the provider terminal 300. In other words, the value of the item "measurement target image" is identification information for identifying the image data of the material. The image data of the material may be stored separately from the quality information, while being associated with its file name.
[0052]
The value of the item "measurement condition” indicates a condition when the measurement device 500 measured the property of the material. Specifically, the value of the item "measurement condition" may be a measurement device identification number for identifying the measurement device 500.

[0079]
Referring now to FIGs. 6 to 8, processing for storing quality information according to the present embodiment is described below. FIG. 6 is a sequence diagram illustrating the operation performed by the material management system 100 according to the first embodiment.
[0080]
In the present embodiment, as the provider terminal 300 receives an operation for instructing registration of quality information of a material in the material management system 100, the provider terminal 300 displays a guidance screen for storing the quality information in the material management apparatus 200 (step S601).
[0081]
In response to the input reception unit 350 receiving an operation for instructing the measurement device 500 to measure the material via the guidance screen (step S602), the communication controller 340 of the provider terminal 300 transmits an instruction that instructs the measurement device 500 to start measuring the material (step S603).
[0082]
In response to the reception of the instruction instructing the start of measurement, the measurement device 500 measures a property of the material (step S604), and transmits the measurement data, which is a result of the measurement, to the provider terminal 300 (step S605).
[0083]
In response to obtaining the measurement data, at the provider terminal 300, the display controller 360 causes the display 318 to display an image capturing screen for requesting the user to capture an image of the material (step S606). The provider terminal 300 receives an operation to capture an image of the material, and acquires image data of the material that is captured (step S607).
[0084]
Subsequently, the provider terminal 300 obtains the image data of the material, and causes the display controller 360 to display on the display 318 an input screen for inputting additional data (step S608). The provider terminal 300 then receives an input of the additional data at the input reception unit 350 (step S609).
[0085]
The image capturing screen and the input screen may be displayed in an order different from the order described above. For example, in the present embodiment, the provider terminal 300, which acquires the measurement data, may display the input screen first. In response to the completion of the input of the additional data, the provider terminal 300 displays the image capturing screen.
[0086]
Referring back to FIG. 6, the communication controller 340 of the provider terminal 300 transmits the measurement data and the additional data to the material management apparatus 200 (step S610).
[0087]
At the material management apparatus 200, as the data input 261 of the quality information manager 260 acquires the measurement data and the additional data (step S611), the quality information generator 263 generates the quality information (step S612).
[0088]
Subsequently, the storage controller 262 of the material management apparatus 200 stores the measurement data in the measurement database 250 and the quality information in the quality information database 240, respectively (step S613). In the present embodiment, the measurement data is stored in the measurement database 250; however, both the quality information and the measurement data may be stored in the quality information database 240. That is, the measurement data and the quality information may be stored in any desired memory.
[0089]
Referring now to FIG. 7, processing performed by the quality information generator 263 is described below according to the present embodiment. FIG. 7 is a flowchart illustrating processing performed by the quality information generator 263 according to the first embodiment.
[0090]
The quality information generator 263 obtains the measurement data and the additional data, and extracts the date and time of measurement, the material name, and the impurity information each from the measurement data (step S701).
[0091]
Specifically, the quality information generator 263 analyzes the near-infrared light spectrum included in the measurement data, and identifies the material name that matches the analysis result. The information associating the analysis result of the measurement data and the material name may be stored in the material management apparatus 200 or may be stored in a storage device residing on a network in a manner that is communicable with the material management apparatus 200.
[0092]
The quality information generator 263 analyzes the near-infrared light spectrum included in the measurement data, and determines a type and a proportion of the impurity contained in the material. The quality information generator 263 extracts information indicating the measurement date and time, from the measurement data.
[0093]
The quality information generator 263 then compares the date and time of acquisition of the image data that is obtained as the additional data and represents an image of the material, with the date and time of measurement that is extracted at step S701 (step S702). The date and time
of acquisition of the image data is the date and time when the image of the material is captured at the provider terminal 300. Such date and time are obtained from metadata added to the image data at the provider terminal 300.
[0094]
When a difference between the date and time of acquisition of the image data and the date and time of the measurement is not within a predetermined range at step S702, the material management apparatus 200 transmits an error notification to the provider terminal 300 (step S704), and the operation ends.
[0095]
When the difference between the date and time of acquisition of the image data and the date and time of the measurement is within the predetermined range at step S702, the quality information generator 263 stores the measurement data in the measurement database 250, in association with the information indicating a storage location of the measurement data, the date and time of the measurement, the material name, the impurity information, and the additional data (step S705).
[0096]
The quality information generator 263 stores the information indicating the storage location of the measurement data, the date and time of the measurement, the material name, the impurity information, and the additional data, in the quality information database 240 as the quality information (step S706). The operation then ends.
[0097]
As described above, in the present embodiment, the quality information is generated, based on a determination that a difference between the date and time of acquisition of the image data and the date and time of the measurement is within the predetermined range.
[0098]
The case where the difference between the date and time of acquisition of the image data and the date and time of the measurement is within the predetermined range indicates that the measurement of a property of the material by the measurement device 500 and capturing of the image of the material by the provider terminal 300 are performed at the same time or substantially at the same time.
[0099]
In the present embodiment, the time when the measurement is performed on a certain material and the time when the image is captured for the certain material are compared, and a result of the comparison is used for verification. This prevents the measurement data and the image data of different materials from being erroneously associated with each other, thus increasing the accuracy of the quality information.
[0100]

[0138]
Accordingly, in the present embodiment, the material management system 100 allows the business operator who uses a certain material of waste to easily check the quality of such material.
[0139]
Referring to FIGs. 12, 13A and 13B, the operation of verifying the quality of the material obtained by the business operator as the user, performed by the user terminal 400, according to the present embodiment is described below.
[0140]
FIG. 12 is a sequence diagram illustrating the operation performed by the material management system 100 according to the first embodiment.
[0141]
In the material management system 100, in response to the input reception unit 450 receiving an operation for instructing verification of the quality of the material, the display controller 460 of the user terminal 400 displays a guidance screen on the display of the user terminal 400 (step S 1201).
[0142]
Subsequently, in response to the input reception unit 450 receiving an operation for instructing to acquire the measurement data of the obtained material via the guidance screen (step S1202), the user terminal 400 transmits an instruction that instructs to start measurement to the measurement device 600 (step S1203).
[0143]
In response to the reception of the instruction that instructs the start of measurement, the measurement device 600 measures a property of the material (step S1204), and transmits the measurement data, which is a result of the measurement, to the user terminal 400 (step S1205).
[0144]
When the user terminal 400 acquires the measurement data, the display controller 460 displays a verification screen on the display of the user terminal 400 (step S 1206). Subsequently, the user terminal 400 receives input of information to the verification screen by the input reception unit 450 (step S1207).
[0145]
The information input to the verification screen includes, for example, a material name of the material obtained by the business operator as the user and the name of the business operator providing such material.
[0146]
When the information is input, the communication controller 440 of the user terminal 400 transmits a verification request to verify the measurement data to the material management apparatus 200 (step S 1208). The verification request includes the measurement data acquired by the user terminal 400 from the measurement device 600 and the information input at step S1207.
[0147]
At the material management apparatus 200, in response to the data input 261 receiving the verification request, the verification unit 267 identifies a specific measurement device 600 from the measurement data included in the verification request (step S1209). Specifically, the verification unit 267 extracts a measurement device identification number for identifying the specific measurement device 600 used for measurement, from the measurement data included in the verification request.
[0148]
Subsequently, the verification unit 267 of the material management apparatus 200 specifies measurement data to be verified with the measurement data included in the verification request, from among the measurement data stored in the measurement database 250 (step S1210). Specifically, the verification unit 267 specifies the measurement data, which is associated with quality information including the material name and the business operator name each having been input, in the measurement database 250 at step S 1207. [0149]
Subsequently, at the material management apparatus 200, the verification unit 267 refers to adjustment data stored in the adjustment data storage unit 268, to adjust two sets of measurement data for verification (step S1211).
[0150]
The two sets of measurement data for verification are, specifically, the measurement data acquired from the user terminal 400 at step S1208 and the measurement data specified at step S1210.
[0151]
The processing of step S 1211 is described below.
[0152]
In general, when the same material is measured separately by the measurement device 500 and the measurement device 600, even if the measurement device 500 and the measurement device 600 are of the same model, the measurement data output from the measurement device 500 and the measurement data output from the measurement device 500 may not completely match.
[0153]
One of the factors causing such a mismatch is that each measurement device has a unique characteristic. In view of the above, in the present embodiment, the adjustment data storage unit 268 stores adjustment data for adjusting data to compensate a characteristic unique to an individual measurement device, in association with a measurement device identification
number for identifying each measurement device. The measurement data is adjusted using the adjustment data.
[0154]
Specifically, when the verification unit 267 acquires the measurement data from the user terminal 400, the verification unit 267 refers to the adjustment data storage unit 268, and adjusts the measurement data using the adjustment data associated with the measurement device identification number included in the measurement data.
[0155]
The verification unit 267 refers to the adjustment data storage unit 268, and adjusts the measurement data specified at step S 1208 by using the adjustment data associated with the measurement device identification number included in the quality information for the specified measurement data. In the present embodiment, the measurement data may be adjusted before the measurement data is stored in the measurement database 250, and the adjusted measurement data may be stored in the measurement database 250.
[0156]
Subsequently, the verification unit 267 verifies the two sets of adjusted measurement data (step S 1212), and transmits information indicating the verification result to the user terminal 400 via the data output 266 (step S 1213).
[0157]
When the information indicating the verification result is received, the user terminal 400 causes the display controller 460 to display, on the display, a verification result screen including the information indicating the verification result (step S 1214). The operation then ends.
[0158]
FIGs. 13 A and 13B are diagrams each illustrating an example screen displayed by the user terminal 400 according to the first embodiment. FIG. 13A illustrates a screen 131, which is an example of the verification screen displayed on the user terminal 400 at step S1206 of FIG. 12.
[0159]
The screen 131 includes a display area 131a and an operation button 131b. The display area 131a includes an input field for inputting the name of the material acquired by the business operator as the user, and an input field for inputting the name of the business operator that has provided such material.
[0160]
In the present embodiment, when the input to the two input fields is completed and the operation button 131b is pressed, the user terminal 400 transmits a verification request to the material management apparatus 200.
[0161]
Further, in response to pressing of the operation button 131b on the screen 131, the user terminal 400 changes the display from the screen 131 to a screen 132 illustrated in FIG. 13B.
[0162]
FIG. 13B illustrates a screen 132, which is an example of a verification result screen displayed on the user terminal 400 at step S 1213 of FIG. 12.
[0163]
The screen 132 includes display areas 132a and 132b. The display area 132a displays a material name and a business operator name, input in the display area 13 la of the screen 131. The display area 132b displays information indicating the verification result generated at the material management apparatus 200.
[0164]
In the example of FIG. 13B, the display area 132b displays the verification result indicating that the measurement data match. Alternatively, the display area 132b may display another screen in the present embodiment. For example, when the verification result indicates that the measurement data do not match, the display area 132b displays information indicating a difference between the two sets of measurement data obtained through verification.
[0165]
As described above, in the present embodiment, the measurement data of the material obtained by the business operator as the user is verified with the measurement data corresponding to the quality information, which is stored by the business operator as the provider. The result of such verification is presented to the business operator as the user of the material. Thus, according to the present embodiment, in a case where the quality of the material checked before obtaining the material, is different from the quality of the material that is obtained, the business operator using the material may request the business operator who provides the material to ensure the adequate compensation.
[0166]
As described above, in the present embodiment, the quality information indicating the quality of the material of waste is shared between the provider and the user. This can eliminate the process of confirming the quality of the material in the transaction, thus, facilitating the transaction process.
[0167]
In the present embodiment, the provider terminal 300 and the user terminal 400 acquire measurement data by communicating with the measurement device 500 and the measurement device 600, respectively, and transmit the acquired measurement data to the material management apparatus 200. However, the measurement data may be acquired in various other ways. For example, the material management apparatus 200 may directly acquire the measurement data from the measurement device 500 and the measurement device 600, respectively. In such case, the provider terminal 300 and the user terminal 400 do not have to acquire the measurement data from the measurement device 500 and the measurement device 600, respectively.
[0168]
Second Embodiment
The second embodiment will be described below with reference to the drawings. The second embodiment is an embodiment in which the first embodiment is applied to traceability management in a supply chain, through a series of processes from collection to recycling of industrial waste. The description of the second embodiment is given of the differences from the first embodiment. Like reference signs denote like elements as those of the first embodiment, and redundant descriptions thereof are omitted or simplified appropriately. [0169]
FIG. 14 is a diagram illustrating a system configuration of a material management system 100A according to the second embodiment.
[0170]
The material management system 100A according to the present embodiment is used to manage supply chain traceability, and tracks a material of the industrial waste through a series of processes in the supply chain from discharge of industrial waste to recycling of the industrial waste.
[0171]
The material management system 100A according to the present embodiment manages the quality of the material of industrial waste, traded between business operators in a supply chain, through a series of processes from collection to recycling (reuse) of industrial waste. [0172]
The material management system 100A according to the present embodiment includes one or more material management apparatuses 200A - 1, 200A - 2,..., 200A - n and one or more terminal apparatuses 700 - 1, 700 - 2,..., 700 - n. In the following description, the material management apparatuses 200A - 1, 200A - 2,..., 200A - n are collectively referred to as the material management apparatus 200A when they are not distinguished from each other, and the terminal apparatuses 700 - 1, 700 - 2,..., 700 - n are collectively referred to as the terminal apparatus 700 when they are not distinguished from each other.
[0173]
The material management apparatus 200A and the terminal apparatus 700 are communicably connected with each other via a network. The material management apparatuses 200A are each a distributed ledger node included in the blockchain system, and are connected to each other by a peer-to-peer (P2P) network. The terminal apparatus 700 according to the present embodiment may be used by each of the business operators in the supply chain. [0174]
In the present embodiment, it is assumed that the business operators in the supply chain include a disposal operator, a treatment operator, a material producer, a manufacturer, and a brand owner.
[0175]
The processes in the supply chain according to the present embodiment include, for example, a process performed by the disposal operator, a process performed by the treatment operator,
a process performed by the material producer, a process performed by the manufacturer, and a process performed by the brand owner.
[0176]
The discharge operator is a business operator, who sorts the industrial waste into a plurality of materials and stores the materials. The process performed by the discharge operator is sorting of the collected industrial waste into different materials and storing of the materials. The treatment operator is a business operator, who applies intermediate treatment or regeneration treatment on the material. The process performed by the processing business operator is intermediate treatment or regeneration treatment on the material.
[0177]
The material producer is a business operator, who manufactures a material of a product from a material (raw material) to which intermediate treatment is applied, and sells the produced material. The process performed by the material producer is the manufacturing of a material of a product from a raw material to which intermediate treatment is applied, and the selling of such material. The manufacturer is a business operator, who manufactures a product by molding the material purchased from the material producer, and selling the manufactured product. The process performed by the manufacturer is manufacturing of a product by molding the material purchased from the material producer, and selling of such product. [0178]
The brand owner is a business operator who purchases the product manufactured by the manufacturer and sells the purchased product. The process performed by the brand owner is selling of the product.
[0179]
In the following description, in a series of processes from collection to recycling of industrial waste, the process of sorting the industrial waste into a plurality of materials and storing the materials by the disposal operator is the most upstream, and the process of selling a product by the brand owner is the most downstream.
[0180]
In the example of FIG. 14, among the terminal apparatuses 700, the terminal apparatus 700 - 1 is used by the discharge operator, the terminal apparatus 700 - 2 is used by the treatment operator, and the terminal apparatus 700 - 3 is used by the material producer. Still referring to the example of FIG. 14, the terminal device 700 - 4 is used by the manufacturer, and the terminal device 700 - 5 is used by the brand owner.
[0181]
Although not illustrated in FIG. 14, the terminal apparatuses 700 may each be connected to the measurement device 500 of its own so as to communicate with the measurement device 500.
[0182]
The material management apparatus 200A according to the present embodiment includes a quality information database 240A, a measurement database 250, a quality information manager 260A, a ranking database 280, and an evaluation database 290.
[0183]
The quality information database 240A according to the present embodiment stores quality information indicating the quality of the material traded between the business operators. The quality information according to the present embodiment includes information indicating a transaction history of a material included in a resource, such as the industrial waste.
[0184]
The ranking database 280 stores information used for determining a rank of the quality of the material in the resource, which has been traded between the business operators. The evaluation database 290 stores evaluation information indicating an evaluation of each business operator. The evaluation database 290 serves as an evaluation information storage unit that stores the evaluation information of a business operator.
[0185]
In generating the quality information of the material in the resource, the quality information manager 260A according to the present embodiment refers to the ranking database 280 to determine a rank of the quality of the material in the resource, and includes information indicating the rank in the quality information.
[0186]
Further, in displaying the quality information on the terminal apparatus 700, the quality information manager 260A according to the present embodiment displays the evaluation information indicating an evaluation of the business operator, who is a source of the resource. [0187]
In the material management system 100A according to the present embodiment, for example, when the disposal operator sorts the industrial waste into different materials, the terminal apparatus 700 - 1 stores quality information of each material that is sorted, in the material management apparatus 200A. The quality information that is generated includes, for example, identification information for identifying a collection source of the industrial waste. In other words, the quality information may include identification information for identifying a process performed immediately before the process of sorting that is performed by the disposal operator.
[0188]
In the material management system 100A, for example, when the treatment operator purchases the material from the disposal operator, the terminal apparatus 700 - 2 acquires the quality information of the material to be purchased, from the material management apparatus 200A.
[0189]
In the material management system 100A, after the treatment operator applies the treatment to the material purchased from the disposal operator, the terminal apparatus 700 - 2 stores the
quality information indicating the quality of the material in the resource, which has been treated, in the material management apparatus 200A. At this time, the quality information includes identification information for identifying the quality information of the material, which is acquired when the treatment operator purchases the material from the disposal operator. In other words, the quality information may include identification information for identifying a process performed immediately before the process of applying treatment that is performed by the treatment operator.
[0190]
In the material management system 100A, for example, when the material producer purchases the material in the resource from the treatment operator, the terminal apparatus 700 - 3 acquires the quantity information of the material to be purchased from the material management apparatus 200A.
[0191]
In the material management system 100A, after the material producer produces a material from the material, which is raw material, purchased from the treatment operator, the terminal apparatus 700 - 3 stores the quality information indicating the quality of the material in the material management apparatus 200A. At this time, the quality information stored by the terminal apparatus 700-3 includes identification information for identifying the quality information of the material, which is acquired when the material is purchased from the treatment operator. In other words, the quality information may include identification information for identifying a process performed immediately before the process of production that is performed by the material producer.
[0192]
In the material management system 100A, for example, when the manufacturer purchases the material from the material producer, the terminal apparatus 700 - 4 acquires the quality information of the material to be purchased from the material management apparatus 200A. [0193]
In the material management system 100A, after the manufacturer manufactures a product from the material purchased from the material producer, the terminal apparatus 700 - 4 stores the quality information indicating the quality of the product in the material management apparatus 200A. At this time, the quality information stored by the terminal apparatus 700-4 includes identification information for identifying the quality information of the material, which is acquired when the material is purchased from the material producer. In other words, the quality information includes identification information for identifying a process performed immediately before the process of manufacturing that is performed by the manufacturer. [0194]
In the material management system 100A, for example, when the brand owner purchases the product from the manufacturer, the terminal apparatus 700 - 5 acquires the quality information of the product to be purchased from the material management apparatus 200A. [0195]
In this way, in the present embodiment, when generating the quality information of the material to be sold by each business operator, each business operator causes the material management apparatus 200A to store the quality information, which includes the identification information for identifying the quality information of the material that is obtained when purchasing the material from the upstream business operator.
[0196]
In other words, in the present embodiment, the quality information is generated or updated to reflect the quality information at each process in the series of processes in the supply chain, and recorded on the blockchain. In the present embodiment, the quality information recorded on the blockchain includes identification information for identifying the process immediately before the current process.
[0197]
In the present embodiment, with the quality information managed throughout the series of processes on the blockchain, falsification of the quality information is prevented. In addition, in the present embodiment, the business operator can prove a source of the material, handled by the business operator, to a transaction counterpart. In other words, when the business operator sells a resource to a downstream business operator, the business operator can present the quality information of a material, which is a raw material of such resource, to the downstream business operator.
[0198]
In the present embodiment, when the business operator purchases a resource, the business operator can trace back the quality information of a material, which is a raw material of the resource, handled by an upstream business operator. In other words, according to the present embodiment, the business operator in the supply chain can view the quality information indicating the quality of the material in the resource, at any processing before the current process to be performed by the business operator.
[0199]
Therefore, according to the present embodiment, the upstream business operator allows the downstream business operator to check the source of the recycled resource, thus, increasing the reliability of transactions between the business operators.
[0200]
Further, according to the present embodiment, the downstream business operator can view the quality of the raw material of the resource to be traded, by tracing back the quality information of the material that is most upstream in the supply chain.
[0201]
For example, it is assumed that the downstream business operator is the treatment operator and the upstream business operator is the discharge operator. In the transaction of a material, the quality information may be used in the negotiation of purchase conditions of the material to be traded, such as a price, delivery date, and purchase amount of the material. Similarly,
the quality information may be used in deciding various other conditions of the material to be traded, such as a condition for cleaning or a condition for removing impurities.
[0202]
In another example, in a case where the downstream business operator is the material producer and the upstream business operator is the treatment operator, the quality information may be used in the negotiation of purchase conditions of the material to be traded, such as a price, delivery date, and purchase amount of the material, or checking of purities of the material to be traded.
[0203]
In another example, in a case where the downstream business operator is the manufacturer and the upstream business operator is the material producer, the quality information may be used in the negotiation of purchase conditions of the material to be traded, such as a price, delivery date, and purchase amount of the material. Similarly, the quality information may be used in checking whether the purity of the material to be traded is suitable for the product, or determining processing conditions of the product.
[0204]
In another example, in a case where the downstream business operator is the brand owner and the upstream business operator is the manufacturer, the quality information may be used in the negotiation of purchase conditions of the product subject to transaction, such as a price, delivery date, and purchase amount of the product.
[0205]
Referring now to FIG. 15, functions of the material management apparatus 200 A are described below according to the second embodiment. FIG. 15 is a diagram illustrating a quality information database according to the second embodiment.
[0206]
The quality information database 240A according to the present embodiment stores quality information, which includes, in addition to the information items of the quality information of FIG. 4 for the first embodiment, quality information ID, quality information ID of used resource, and a rank.
[0207]
The value of the item "quality information ID" is identification information for identifying quality information. Specifically, the value of the item "quality information ID" is identification information for identifying a resource (material) to be traded between business operators. In other words, the value of the item "quality information ID" is identification information for identifying a process currently performed by the business operator. The value of the item "rank" is information indicating a rank of the quality of the resource (material) corresponding to the quality information described above. For example, the rank indicates whether the quality of the material is good or bad.
[0208]
The value of the item "quality information ID of used resource" is identification information for identifying quality information of raw material of the resource, of which quality is indicated by the quality information. In other words, the value of the item "quality information ID of used resource" is identification information for identifying a process immediately before the current process performed by (or to be performed by) the business operator that stores the quality information.
[0209]
In the quality information database 240A, the value of the item “quality information ID" and the value of the item "rank" may be values generated by the material management apparatus 200A. The value of the item “quality information ID of used resource" may be a value input on the additional data input screen.
[0210]
Referring now to FIG. 16, the functions performed by the material management apparatus 200A according to the present embodiment are described below. FIG. 16 is a diagram illustrating a functional configuration of the material management apparatus 200A according to the second embodiment.
[0211]
The ranking database 280 of the material management apparatus 200A according to the present embodiment is referred to when generating the quality information. Specifically, the ranking database 280 stores reference information, which can be a basis to determine whether the quality of the resource (material), indicated by the quality information, is good or bad. The reference information includes, for example, information indicating a type of impurity, or a threshold value for the proportion of the impurity, contained in the material. The evaluation database 290 stores evaluation information for the business operator.
[0212]
The quality information manager 260A according to the present embodiment includes a data input 261, a storage controller 262, a quality information generator 263 A, a list obtainer 264, a quality information obtainer 265, a data output 266, a verification unit 267, and an evaluation unit 269.
[0213]
The quality information generator 263A according to the present embodiment issues a quality information ID for identifying the quality information when generating the quality information. The quality information ID that is issued is included in the quality information. The quality information generator 263A refers to the ranking database 280 to determine a rank of the quality of the resource to indicate whether the quality of the resource is good or bad.
[0214]
When information indicating an evaluation of a particular business operator is input from the terminal apparatus 700, the evaluation unit 269 according to the present embodiment updates the evaluation information of the particular business operator in the evaluation database 290.
Specifically, the evaluation unit 269 extracts evaluation information, which is associated with a business operator ID of the particular business operator subject to the input of a new evaluation, from the evaluation information stored in the evaluation database 290. The evaluation unit 269 then performs statistical processing on the extracted evaluation information including the newly input evaluation, and updates the evaluation information of the particular business operator.
[0215]
Although the description is omitted in FIG. 16, the terminal apparatus 700 includes a communication controller, an input reception unit, and a display controller, similarly to the provider terminal 300 and the user terminal 400 illustrated in FIG. 5.
[0216]
Referring to FIG. 17, processing performed by the quality information generator 263A is described below according to the present embodiment. In the material management system 100A according to the present embodiment, the operation of storing the quality information in the quality information database 240A is the same as that of the sequence diagram of FIG. 6, except that the provider terminal 300 is replaced by the terminal apparatus 700 of FIG. 14 and the processing of the quality information generator 263A is performed as described below. [0217]
FIG. 17 is a flowchart illustrating processing performed by the quality information generator 263A according to the second embodiment. The quality information generator 263A obtains the measurement data and the additional data, and extracts the date and time of measurement, the material name, and the impurity information from the measurement data (step S 1701). [0218]
Subsequently, the quality information generator 263A determines a rank of the quality of the resource (material), based on the impurity information extracted from the measurement data at step S1701 and information in the rank database 280 (step S1702).
[0219]
For example, the quality information generator 263A may determine that the quality has a rank “excellent” when a proportion of the impurity indicated by the impurity information extracted at step S1701 is less than a threshold stored in the ranking database 280. The quality information generator 263A may further determine that the quality has a rank “good” when such proportion of the impurity is equal to or greater than the threshold. The threshold indicating the proportion of the impurity may have multiple values according to multiple stages of the threshold. The quality information generator 263A may determine a rank of the quality of the material, according to a corresponding stage of the threshold. The processing of determining a rank based on the impurity proportion, performed by the quality information generator 263 A, is described below in more detail.
[0220]
Alternatively, the quality information generator 263A according to the present embodiment may determine a rank of the quality of the material, according to a type of impurity included
in the impurity information. For example, the quality information generator 263A may set the rank of the quality to “acceptable”, when a certain type of impurity is included in the material. [0221]
The quality information generator 263A proceeds to step S1702 following step S1703. Since the processing from step S1703 to step S1705 of FIG. 17 is the same as the processing from step S702 to step S704 of FIG. 7, the description thereof is omitted.
[0222]
When the difference between the date and time of acquisition of the image data and the date and time of the measurement is within the predetermined range at step S1704, the quality information generator 263A stores the measurement data in the measurement database 250, in association with the information indicating a storage location of the measurement data, the date and time of the measurement, the material name, the impurity information, the additional data, and the rank (step S 1706).
[0223]
Subsequently, the quality information generator 263A issues a quality information ID, which is identification information for identifying the quality information (step S1707).
[0224]
The quality information generator 263A stores the information indicating the storage location of the measurement data, the date and time of the measurement, the material name, the impurity information, the additional data, the rank, and the quality information ID, in the quality information database 240 as the quality information (step S1708).
[0225]
The additional data according to the present embodiment includes the quality information ID of the used resource. The quality information ID of the used resource may be input on the additional data input screen displayed on the terminal apparatus 700 in a substantially similar manner as described above referring to step S608 of FIG. 6, for example.
[0226]
Referring now to FIGs. 18A and 18B, the processing of determining a rank based on the impurity proportion, performed by the quality information generator 263 A, is described according to the embodiment. FIGs. 18A and 18B are graphs for explaining reference information to be used for determining a rank based on the impurity proportion, according to the present embodiment.
[0227]
The ranking database 280 stores, for example, absorbance waveform data of a resource (for example, plastic) formed of a resin containing 100% polypropylene (PP), and absorbance waveform data of a resource formed of a resin containing 100% polyethylene (PE), as the reference information to be used for determining a rank of the quality of the resource.
[0228]
In FIG. 18 A, the horizontal axis represents wavelengths, and the vertical axis represents absorbance expressed in secondary differentiation. In FIG. 18A, a curve LI represents the
absorbance waveform of a material formed of 100% polypropylene (PP). Further, in FIG. 18A, a curve L2 represents the absorbance waveform of a material formed of 100% polyethylene (PE). In FIG. 18 A, a curve L3 represents a waveform, indicated by the measurement data of a material that is measured.
[0229]
In the present embodiment, an absorbance waveform of a specific material that does not contain impurities or additives and is not coated, is referred to as a first waveform. Further, in the present embodiment, an absorbance waveform of an impurity is referred to as a second waveform. Examples of the impurity, which is preferably not to be contained in the material, include PE (polyethylene).
[0230]
In the following description, the absorbance waveform of the material formed of 100% polypropylene (PP), which is indicated by the curve LI, serves as the first waveform. The absorbance waveform of the material formed of 100% polyethylene (PE), which is indicated by the curve L2, serves as the second waveform. In the following description, the waveform represented by the measurement data of the material that is measured, indicated by the curve L3, serves as a measured waveform.
[0231]
The quality information generator 263A according to the present embodiment synthesizes the first waveform and the second waveform using the multiple regression analysis, such that a correlation coefficient with the third waveform becomes maximum. FIG. 18B illustrates a curve L4, which indicates a combined waveform obtained by synthesizing the first waveform and the second waveform. In the example of FIG. 18B, the proportion of the first waveform in the combined waveform is 76.7%, and the proportion of the second waveform in the combined waveform is 23.3%.
[0232]
Accordingly, of the material subjected to the quality determination, a proportion of PP (polypropylene) is 76.7%, and a proportion of PE (polyethylene) is 23.3%. In the present embodiment, the quality of the material is determined according to the proportion of PP (polypropylene) and the proportion of PE (polyethylene) contained in the material. [0233]
Specifically, in the present embodiment, thresholds are set in a stepwise manner, with respect to the proportion of PP (polypropylene) to the combined waveform generated using the multiple regression analysis. The quality of the material is determined based on the thresholds and the proportion of PP (polypropylene) in the combined waveform. In other words, the quality information generator 263A determines a rank of the quality of the material, according to the proportion of the impurity in the combined waveform. The threshold value for the proportion of PP (polypropylene) in the combined waveform may be stored in the ranking database 280.
In the present embodiment, for example, among the thresholds set in a stepwise manner, the first threshold is set to 95% and the second threshold is set to 80%. In such case, the quality information generator 263A determines that the material in which the proportion of PP (polypropylene) in the combined waveform is 95% or more has the rank “excellent”. The quality information generator 263A determines that the material in which the proportion of PP (polypropylene) in the combined waveform is 80% or more and less than 95% has the rank “good”. The quality information generator 263A determines that the material in which the proportion of PP (polypropylene) in the combined waveform is less than 80% has the rank "acceptable".
[0235]
Therefore, the material from which the measured waveform L3 illustrated in FIGs. 18A and 18B is obtained is determined to have a rank “acceptable".
[0236]
In the above description, the absorbance waveform data indicating the first waveform and the second waveform, respectively, are stored in the ranking database 280. However, the absorbance waveform data corresponding to the second waveform may not be stored in the ranking database 280. In other words, the absorbance waveform data of the impurity may not be stored in the ranking database 280.
[0237]
In such case, the quality information generator 263 A calculates a correlation coefficient between the measured waveform and the first waveform, and determines whether the quality of the material is good or bad according to the calculated correlation coefficient. More specifically, a threshold value for the correlation coefficient is set and stored in the ranking database 280 so that the quality of a material having a high correlation coefficient is determined to be a material having good quality.
[0238]
For example, the threshold value for the correlation coefficient may be set such that the rank of a material having a coefficient of 0.99 or more is determined as "excellent", the rank of a material having a coefficient of 0.98 or more and less than 0.99 is determined as "good", and the rank of a material having the coefficient of less than 0.98 is determined as "acceptable". [0239]
In the present embodiment, in a case that the material to be measured is a material to which a certain amount of additive is added to impart a specific function, the state in which the certain amount of additive is added is regarded as the best state for such material. In this case, the ranking database 280 may store absorbance waveform data of a material to which a certain amount of additive is added as reference information for determining whether the quality of the material to be measured is good or bad. The quality information generator 263A calculates a correlation coefficient between a waveform indicated by the absorbance waveform data of the material to which the certain amount of the additive is added, and a waveform of the
material to be measured, and determines a rank of the material to be measured according to the correlation coefficient.
[0240]
In this way, even when the material to be measured contains an additive or is coated, the quality of the material is determined with high accuracy.
[0241]
Further, in the present embodiment, when none of the absorbance waveform data indicating the first waveform and the absorbance waveform data indicating the second waveform are stored in the ranking database 280, a rank of the quality of the material may be determined based on, for example, the level of brightness or the level of transparency of the image obtained by capturing the material to be measured.
[0242]
In the present embodiment, the accuracy of the information indicating the quality of the material to be measured increases, thus contributing to facilitation of transactions of the material.
[0243]
Referring now to FIGs. 19 and 20, the operation of displaying quality information on the terminal apparatus 700 according to the present embodiment is described below.
[0244]
