- ⁇ Processing Description> 6 is a flow diagram showing an example of a recommended material search process. This process is executed by the processor 20 that has read the material search program 211 when the recommended material search device 100 receives a search request for a recommended material from the external device 10.
- the processor 20 accepts input of the reference material from the external device 10 (step S10). Specifically, the processor 20 accepts input of, for example, the name and type of the reference material from a search user of the external device 10.
- the processor 20 acquires the material information of the reference material that has been input (step S20). Specifically, the processor 20 retrieves the corresponding material information from the material information DB 110 based on the name and type of the input reference material. The processor 20 also acquires the corresponding physical property information and molding quality information from the physical property information DB 120 and molding quality information DB 130, respectively, based on the identification information 110a of the retrieved material information.
- the processor 20 accepts the selection of a physical property evaluation item and the input of an evaluation physical property value (step S30). Specifically, the processor 20 accepts the selection of a physical property evaluation item that the search user places importance on from among a plurality of physical property evaluation items that correspond to the physical property values 120d in the physical property information of the reference material, such as the elastic modulus in mechanical properties and the crystallization temperature in thermal properties. For example, if the elastic modulus, tensile strength, and melting temperature are registered as the physical property values 120d in the physical property information of the reference material, the processor 20 accepts the selection of the physical property evaluation items that the search user places importance on from among these (e.g., tensile strength and melting temperature).
- the processor 20 accepts the selection of the physical property evaluation items that the search user places importance on from among these (e.g., tensile strength and melting temperature).
- the processor 20 also accepts input of evaluation property values for the selected physical property evaluation items. For example, if modulus of elasticity and crystallization temperature are selected as physical property evaluation items, the processor 20 accepts the numerical range of modulus of elasticity and crystallization temperature desired (accepted) by the search user as the evaluation property value.
- the processor 20 determines search conditions for the candidate materials (step S40). Specifically, the processor 20 determines the input physical property evaluation items and evaluation physical property values as search conditions for the candidate materials.
- the processor 20 may also include the type of reference material in the search conditions. By including the type of reference material as a search condition, the processor 20 can narrow the search range to a narrower range, thereby reducing the processing load.
- the processor 20 executes a search for candidate materials (step S50). Specifically, the processor 20 searches the physical property information DB 120 and the material information DB 110 based on the search conditions, and identifies candidate materials that satisfy the search conditions. Note that typically, multiple candidate materials that satisfy the search conditions are identified.
- the processor 20 executes a similarity comparison process (step S60). Specifically, the processor 20 compares the similarity between the reference material and the candidate material based on the Euclidean distance between the two materials.
- FIG. 7 is a flow diagram showing an example of a similarity comparison process.
- the processor 20 generates a data plot of the reference material and the candidate material (step S061). Specifically, the processor 20 generates a data plot of the reference material and the candidate material based on predetermined quality evaluation items. More specifically, the processor 20 generates a data plot in which the shrinkage of each of the reference material and the candidate material is quality evaluation item 1 (horizontal axis) and the fluidity is quality evaluation item 2 (vertical axis).
- Figure 8 shows an example of a data plot for a reference material and a candidate material. As shown in the figure, even if the reference material and candidate materials are materials with the same lot number, there is some variation in the molding quality for each measurement. For this reason, the data plot is represented by a cloud of points that show the variation (distribution) of molding quality for each of the reference material and candidate materials.
- the processor 20 standardizes the reference material and the candidate materials based on the statistics (step S062).
- the data plots are data in which the values of the quality evaluation items for different types of materials are expressed as a point cloud, and therefore the absolute values are not consistent. Therefore, the processor 20 uses the data plots to standardize the reference material and the candidate materials based on statistics such as the average value and standard deviation of the materials.
- the normalization is performed using the following equations (2) and (3).
- X'Ai indicates the position of candidate material A in the horizontal direction after standardization.
- XAi indicates the plot position of candidate material A in the horizontal direction before standardization.
- Xo indicates the average value in the horizontal direction of the reference material before standardization.
- ⁇ xo indicates the standard deviation in the horizontal direction of the reference material before standardization.
- Y'Ai indicates the position of the candidate material A in the vertical axis direction after standardization.
- YAi indicates the plot position of the candidate material A in the vertical axis direction before standardization.
- Yo indicates the average value in the vertical axis direction of the reference material before standardization.
- ⁇ yo indicates the standard deviation in the vertical axis direction of the reference material before standardization.
- equations (2) and (3) are used to normalize other candidate materials in a similar manner.
- Figure 9 shows an example of the distribution of forming quality for standardized reference material and candidate materials. Standardization quantifies the variation in forming quality for the reference material and each candidate material, making them mutually comparable.
- the processor 20 calculates the Euclidean distance used in the similarity comparison (step S063). Specifically, the processor 20 calculates the Euclidean distance between the point group (cluster) of the reference material and the point group (cluster) of the candidate material using a known method such as the group averaging method. The calculation of the Euclidean distance d is performed using the following formula (4).
- the above formula (4) represents the sum of the distances of all the standardized plotted points.
- n indicates the number of plots of candidate material A.
- m indicates the number of plots of the reference material.
- i and j are subscripts indicating a point of the sum.
- the formula (4) is also used in the case of other candidate materials.
- the processor 20 compares the similarity between the reference material and the candidate materials (step S64). Specifically, the processor 20 compares the similarity between the reference material and each candidate material based on the magnitude of the Euclidean distance. More specifically, the processor 20 evaluates that the closer the Euclidean distance, the higher the similarity. This is because the similarity is proportional to the Euclidean distance between the reference material and the recommended material, which becomes comparable by standardizing the molding quality.
- the processor 20 also determines the recommendation order of the candidate materials based on the comparison of the similarities (step S65). Specifically, the processor 20 determines the recommendation order of the candidate materials by assigning a higher recommendation order to the materials with higher similarities.
- FIG. 10 is a diagram showing an example of the relationship between the Euclidean distance between a reference material and a candidate material, and the similarity of molding quality.
- the example shown shows that the Euclidean distance from the reference material is closest to the candidate material B, C, and A in that order.
- the processor 20 evaluates the candidate materials B, C, and A in order as having the highest similarity to the molding quality of the reference material, and determines the recommended ranking of each candidate material according to this order.
- step S70 ( Figure 6).
- the processor 20 calculates the environmental impact based on the environmental information (step S70). Specifically, the processor 20 identifies the corresponding environmental information based on the identification information of the candidate material. The processor 20 also uses the identified environmental information to calculate the environmental impact related to a specific environmental load, such as the amount of carbon dioxide emissions. Note that the environmental impact may be the numerical value related to the environmental load registered in the environmental information.
- the processor 20 outputs the search results (step S80). Specifically, the processor 20 generates search results that associate material information for each candidate material with a recommendation ranking, and outputs (transmits) the search results to the search user's computer.
- the processor 20 may also include physical property information and molding quality information for the candidate materials in the search results.
- This type of recommended material search system makes it possible to select more appropriate recommended materials that take molding quality into consideration.
- the recommended material search device quantifies the variation in molding quality such as fluidity and shrinkage, and determines the recommended order by comparing the similarity between the standardized reference material and the candidate materials. Therefore, the recommended material search system can search for recommended materials with appropriate molding quality similar to the molding quality of the reference material.
- search results include information about the environmental impact of the recommended materials, so search users can select suitable materials while also taking the environmental impact into consideration.
- the recommended material search device 100 may also add the cost of the recommended material to the search results.
- the cost-related information may be managed, for example, by linking it to various materials in the material information.
- the search user can select a suitable material by referring to the cost of the recommended material in addition to the similarity to the reference material and the environmental impact.
- the above embodiment was described on the assumption that the material information DB 110, the physical property information DB 120, the molding quality DB, and the environmental information DB 140 are stored in advance in the memory resource 30, but these databases may be stored in another computer (e.g., a cloud server). That is, in this case, the recommended material search system 1000 includes a computer (cloud server) that stores the databases.
- the recommended material search device 100 searches for and acquires the target material information, physical property information, molding quality information, and environmental information from the database of the computer (cloud server) when executing the recommended material search process.
- a recommended material search system configured in this way can also enable the selection of more appropriate recommended materials that take molding quality into consideration.
- the present invention is not limited to the above-mentioned embodiments and modifications, but includes various other embodiments and modifications.
- the above-mentioned embodiments have been described in detail to clearly explain the present invention, and are not necessarily limited to those having all of the configurations described.
- it is possible to replace part of the configuration of one embodiment with the configuration of another embodiment or modification and it is also possible to add the configuration of another embodiment to the configuration of one embodiment.
- control lines and information lines are those that are considered necessary for the explanation, and do not necessarily show all the control lines and information lines in the product. In reality, it can be considered that almost all components are interconnected.
