[0032] The input unit 150 is an input device such as a keyboard, a pointing device, etc. The display unit 155 is a display device such as a liquid crystal display device.

[0033] The storage unit 170 is a HDD, a flash memory, a RAM (Random Access Memory), etc. The storage unit 170 may be a NAS (Network Attached Storage) device that the information processing device 100 can access via a network. The storage unit 170 stores information such as a trained model M and teacher data D.

[0034] The database 200 is a large-capacity storage device accessible by the information processing device 100. In this embodiment, the information processing device 100 and the database 200 are separate devices, but these devices may be integrated.

[0035] The database 200 stores information such as raw material information 210, molded product information 220, product information 230, and recycled material information 240. The information processing device 100 can obtain this information by accessing the database 200.

[0036] For example, the raw material information acquisition unit 105 acquires raw material information 210 by accessing the database 200.

[0037] [Ingredients information] FIG. 3 is a diagram showing an example of the contents of the raw material information 210. In the raw material information 210, for example, form information and type information are associated with a raw material ID. The raw material ID is identification information for identifying a raw material. The form information is information indicating the form of the raw material, such as pellets or crushed material. The type information is information indicating the type of cyclic olefin resin contained in the raw material, for example. The types of cyclic olefin resin will be described later.

[0038] [Molded product information] FIG. 4 is a diagram showing an example of the contents of the molded product information 220. The molded product information 220 is information about a molded product molded using raw materials or recycled materials. For example, the molded product information 220 is information in which type information, material information, and recycle information are associated with a molded product ID. The molded product ID is identification information for identifying a molded product. The type information is information indicating the type of molded product, such as a lens, a film, and a container. The material information is information about raw materials or recycled materials used to mold the molded product. The material information may be, for example, a raw material ID included in the raw material information 210 in FIG. 3 or a recycled material ID to be described later in FIG. 6. The recycle information is information indicating whether or not the molded product is molded using recycled materials (i.e., whether or not it is a recycled product). For example, if the molded product is molded using recycled materials, the recycle information is "Yes". On the other hand, if the molded product is molded using only raw materials, the recycle information is "No".

[0039] [Product Information] FIG. 5 is a diagram showing an example of the contents of the product information 230. The product information 230 is information about a product manufactured using a molded product. For example, the product information 230 is information in which type information, molded product information, recycled content information, and authentication information are associated with a product ID. The product ID is identification information for identifying a product. The type information is information indicating the type of product, such as a smartphone or a camera. The molded product information is information about a molded product used in manufacturing the product. The molded product information may be, for example, the molded product ID included in the molded product information 220 in FIG. 4. The recycled content information is information indicating the proportion of recycled materials in a product. For example, the recycled content information may be the proportion (%) of the weight of recycled materials to the weight of the entire product.

[0040] The authentication information is information indicating whether or not a product has been authenticated as a recycled product. When the authentication unit 140 determines that the proportion of recycled materials in a product is equal to or greater than a predetermined threshold based on the recycling proportion information in the product information 230, it certifies that the product is a recycled product. For example, the authentication unit 140 may set the authentication information to "OK" if the recycling proportion information is 80% or greater, and may set the authentication information to "NG" if the recycling proportion information is less than 80%. "OK" means that the product has been authenticated as a recycled product, and "NG" means that the product has not been authenticated as a recycled product.

[0041] [Recycled material information] FIG. 6 is a diagram showing an example of the contents of the recycled material information 240. The recycled material information 240 is information about recycled materials, which are recycled products of raw materials. In the recycled material information 240, for example, form information, type information, blending information, and quality score are associated with a recycled material ID. The recycled material ID is identification information for identifying the recycled material. The form information is information indicating the form of the recycled material, such as pellets or crushed material. The type information is information indicating the type of cyclic olefin resin contained in the recycled material, for example. The types of cyclic olefin resin will be described later. The blending information is information indicating the blending amount of the recycled cyclic olefin resin in the recycled material. For example, the blending amount may be the ratio of the weight of the recycled cyclic olefin resin to the weight of the entire recycled material. The quality score is information indicating the quality of the recycled material.

[0042] The score calculation unit 135 calculates the quality score using the trained model M, and writes the calculated quality score to the recycled material information 240. A method for calculating the quality score using the trained model M will be described below.

[0043] [Trained model] Fig. 7 is a diagram showing an example of the configuration of a trained model M. The trained model M includes an input layer L1, an intermediate layer L2, and an output layer L3. In Fig. 7, the trained model M includes one intermediate layer L2, but may include multiple intermediate layers L2.

[0044] The calculation unit 130 of the information processing device 100 reads out the trained model M from the storage unit 170. When the calculation unit 130 inputs an input variable to the input layer L1 of the trained model M, an output variable is output from the output layer L3 of the trained model M.

[0045] FIG. 8 is a diagram showing an example of processing performed by the calculation unit 130. As shown in FIG. 8, in this embodiment, an example will be described in which the input variables input to the trained model M are blending information, and the output variables output from the trained model M are optical property information. As described above, the blending information is information indicating the blending amount of recycled cyclic olefin resin in the recycled material. In addition, the optical property information may include at least one of the haze, light transmittance, refractive index, birefringence, and yellow index of a molded product (such as a lens) molded using the recycled material.

[0046] The calculation unit 130 reads out the trained model M from the storage unit 170, and acquires combination information (an example of an input variable) input by a user using the input unit 150. Then, the calculation unit 130 outputs optical property information (an example of an output variable) in response to the input of the combination information (an example of an input variable) based on the trained model M. The calculation unit 130 may display the output optical property information on the display unit 155.

[0047] Figure 9 is a schematic diagram of a part of a neural network used in trained model M. x indicates the value of the unit (node) in each layer. The value of each unit is calculated using a specified function by multiplying the output of the unit in the previous layer by a weight w and adding them together. These can be expressed as the following equation.

[0048]

number

[0049] Here, b is a bias term. The function f may be a ReLU or sigmoid function. The calculation of the above formula (1) is repeated from the input layer L1 to the output layer L3, and the output variables are output from the trained model M.

[0050] The learning unit 125 generates a trained model M by performing machine learning using the teacher data D. "Learning" means adjusting the weights w and bias terms b to appropriate values. Learning is performed by a stochastic gradient descent method or the like. That is, random values ​​are given to the weights w and bias terms b of each layer, and the teacher data D is given to the input layer L1. In the early stages of learning, the output value output from the output layer L3 is an incorrect value, but in the case of the teacher data D, the value (target value) that is originally desired to be output is known, so the weights and the like are updated in reverse order from the output layer L3 to the input layer L1 so that the deviation (error) between the output value and the target value becomes small. This is called error backpropagation, and the error between the output value and the target value is expressed by squared error, cross entropy, or the like. At this time, if the error is expressed by a differentiable function, the amount of adjustment (gradient) to reduce the error can be calculated.

[0051] FIG. 10 is a diagram showing an example of teacher data D. For example, the teacher data D is a teacher data ID to which blending information and optical property information are associated. The teacher data ID is identification information for identifying the teacher data. As described above, the blending information is information indicating the blending amount of the recycled cyclic olefin resin in the recycled material. For example, the blending amount may be the ratio of the weight of the recycled cyclic olefin resin to the weight of the entire recycled material. In addition, the optical property information may include at least one of the haze, light transmittance, refractive index, birefringence, and yellow index of the resin composition.

[0052] The processing of the information processing device 100 of this embodiment includes processing in a learning stage and processing in an operation stage. In the learning stage, the learning unit 125 of the information processing device 100 generates a trained model M by performing machine learning using the teacher data D. That is, the learning unit 125 generates the trained model M by performing machine learning using the blending information as an input variable and the optical property information as an output variable. The learning unit 125 stores the generated trained model M in the storage unit 170.

[0053] Also, in the operation stage, the calculation unit 130 of the information processing device 100 outputs optical property information using the trained model M generated in the learning stage. Specifically, the calculation unit 130 acquires blending information input by a user using the input unit 150. Then, the calculation unit 130 outputs optical property information based on the trained model M in response to the input of the blending information.

[0054] [Score calculation process] The score calculation unit 135 acquires blending information of the recycled materials from the recycled material information 240 shown in Fig. 6, and outputs the acquired blending information to the calculation unit 130. In response to the input of the blending information of the recycled materials, the calculation unit 130 outputs optical property information based on the trained model M. The score calculation unit 135 calculates a quality score based on the optical property information output by the calculation unit 130. The quality score is a score that indicates a higher value as the quality of the recycled material based on the optical property information (haze, light transmittance, refractive index, birefringence, yellow index, etc.) is better.

[0055] 6, the score calculation unit 135 writes the calculated quality score in association with the recycled material ID into the recycled material information 240. The score calculation unit 135 may also display the calculated blending information on the display unit 155. This allows the user to easily understand the quality score for each recycled material.

[0056] [Flowchart of processing by information processing device] 11 is a flowchart showing an example of processing of the information processing device 100. For example, the processing according to this flowchart is executed by the computer of the information processing device 100 executing a program.

[0057] First, the ingredient information acquiring unit 105 of the information processing device 100 acquires the ingredient information 210 from the terminal device 300-1, and records it in the database 200 (S11). The ingredient information 210 includes an ingredient ID, form information, and type information, as shown in FIG.

[0058] Next, the molded product information acquisition unit 110 acquires the molded product information 220 from the terminal device 300-2 and records it in the database 200 (S12). The molded product information 220 includes a molded product ID, type information, material information, and recycle information, as shown in Fig. 4. Since the molded product information 220 acquired here is for a molded product that is molded using only raw materials (a molded product that is not a recycled product), the recycle information is "No."

[0059] Next, the product information acquisition unit 115 acquires the product information 230 from the terminal device 300-3, and records it in the database 200 (S13). The product information 230 includes a product ID, molded product information, recycling ratio information, and authentication information, as shown in FIG.

[0060] Next, the recycled material information acquisition unit 120 acquires the recycled material information 240 from the terminal device 300-4 and records it in the database 200 (S14). As shown in Fig. 6, the recycled material information 240 includes a recycled material ID, form information, type information, blend information, and a quality score.

[0061] Next, the molded product information acquisition unit 110 acquires the molded product information 220 of the recycled product from the terminal device 300-5, and records it in the database 200 (S15). Since what is acquired here is the molded product information 220 of a molded product (recycled product) that is molded using recycled materials, the recycle information becomes "Yes."

[0062] Next, product information acquisition unit 115 acquires product information 230 of the recycled product from terminal device 300-6 and records it in database 200 (S16). For example, if the recycling ratio information is 80% or more, authentication information may be set to "OK", and if the recycling ratio information is less than 80%, authentication information may be set to "NG". This ends the processing according to this flowchart.

[0063] As described above, the monitoring system 10 of this embodiment includes the raw material information acquisition unit 105 that acquires raw material information 210 related to raw materials, and the recycled material information acquisition unit 120 that acquires recycled material information 240 related to recycled materials that are recycled products of the raw materials.

The recycled cyclic olefin resin composition according to the present embodiment may also contain unused cyclic olefin resin (A).

[0070] In this specification, the recovered cyclic olefin resin (A1) and the unused cyclic olefin resin (A) are collectively referred to as "cyclic olefin resin (A)".
