The present invention relates to a management apparatus, a production management system, a management method, a program, and a recording medium, and more particularly, to a technique for managing the manufacturing of a product worn by a user.
Conventionally, various technologies related to production management of products have been proposed. For example, Japanese Unexamined Patent Application Publication No. 2001-273021 discloses a technique of making a production plan for each variety on the basis of a demand prediction, a variety of products, a delivery date, and the like.
The size and shape of a human body vary widely depending on age, gender, race, and the like. Therefore, it is ideal that products worn by users, such as a garment and shoes, are made to order according to the size of each user. However, when manufacturing the product using a manufacturing apparatus, it is practical for users with body shapes that fall within a certain range to be covered with the product in a certain size.
The narrower the range covered by the product in a certain size, the more the product fits the user's body shape, which is preferable in terms of increasing customer satisfaction. On the other hand, narrowing the range covered by the product in a certain size leads to an increase in the number of types of products, which is not preferable from the standpoint of inventory risk.
The present invention focuses on these points, and an object of the present invention is to provide a technique for balancing a variation in size of the product and the inventory risk.
The first aspect of the present invention is a management apparatus for managing manufacturing of a product worn by a user. This management apparatus comprises a feature acquisition part that acquires a plurality of features relating to a body shape of the user, a mapping part that maps and superimposes, for each of a plurality of different users, a density distribution specified by a feature of the plurality of different users on a multi-dimensional feature space having the plurality of features as coordinate axes, a manufacturing data allocation part that allocates, to each of a plurality of different points in the feature space, manufacturing data used for manufacturing a product corresponding to each region in the feature space including coordinates of each point, and a production management part that calculates the number of products to be manufactured using each piece of the manufacturing data on the basis of the coordinates of each of the plurality of different points in the feature space and the density distribution mapped to and superimposed on the feature space.
The second aspect of the present invention is a production management system that comprises the above-mentioned management apparatus, and a manufacturing apparatus that manufactures the product using the above-mentioned manufacturing data. In the production management system, the management apparatus further includes an order reception part that receives an order for the product from a user, and the production management part calculates the number of products to be manufactured by the manufacturing apparatus if the number of orders for the product received by the order reception part is less than the manufacturing capacity of the manufacturing apparatus.
The third aspect of the present invention is a management method for managing manufacturing of a product worn by a user. The method performed by a processor comprises the steps of acquiring a plurality of features relating to a body shape of the user, mapping and superimposing, for each of a plurality of different users, a density distribution specified by a feature of the plurality of different users on a multi-dimensional feature space having the plurality of features as coordinate axes, allocating, to each of a plurality of different points in the feature space, manufacturing data used for manufacturing a product corresponding to each region in the feature space including coordinates of each point, and calculating the number of products to be manufactured using each piece of the manufacturing data on the basis of the coordinates of each of the plurality of different points in the feature space and the density distribution mapped and superimposed on the feature space.
The fourth aspect of the present invention is a non-transitory computer-readable recording medium storing a program for managing manufacturing of a product worn by a user. The program stored in the non-transitory computer-readable recording medium makes a computer perform functions of acquiring a plurality of features relating to a body shape of the user, mapping and superimposing, for each of a plurality of different users, a density distribution specified by a feature of the plurality of different users on a multi-dimensional feature space having the plurality of features as coordinate axes, allocating, to each of a plurality of different points in the feature space, manufacturing data used for manufacturing a product corresponding to each region in the feature space including coordinates of each point, and calculating the number of products to be manufactured using each piece of the manufacturing data on the basis of the coordinates of each of the plurality of different points in the feature space and the density distribution mapped to and superimposed on the feature space.
It should be noted that any combination of the above-described constituent elements, and an aspect obtained by converting the expression of the present invention among methods, apparatus, systems, computer programs, data structures, recording media, and the like are also effective as an aspect of the present invention.
Hereinafter, the present invention will be described through exemplary embodiments of the present invention, but the following exemplary embodiments do not limit the invention according to the claims, and not all of the combinations of features described in the exemplary embodiments are necessarily essential to the solution means of the invention.
An outline of the embodiment will be described while referencing
The management apparatus 1 can mutually communicate with a user terminal T owned by a user U who is an orderer of a product handled by the management apparatus 1 via a network N such as the Internet. The database 2 is a database for storing body shape information of a wearer (i.e. someone who wears the product handled by the management apparatus 1) who resides in a sales area of the product manufactured by the manufacturing apparatus 3. The manufacturing apparatus 3 is an apparatus for manufacturing the product worn by the wearer. The product worn by the wearer includes a garment such as a sweater, underwear, a knit hat, socks, and gloves, and footwear such as shoes and sandals. Here, the wearer of the product may be the user U, or may be a person different from the user U (for example, a family member, a friend, an acquaintance, or the like of the user U).
The plant 4 produces raw materials for the manufacturing apparatus 3 to manufacture the product. By way of illustration, but not limitation, the manufacturing apparatus 3 is a seamless knitting machine capable of knitting a garment three-dimensionally in one entire piece. In this case, the plant 4 may be a plant that produces fibers and the like made of structural proteins as raw materials for the manufacturing apparatus 3 to manufacture the product.
If the user U taps a “detail input” icon on the product order screen shown in
It should be noted that the user U does not have to be the only person who performs input in the product order screen shown in
The management apparatus 1 according to the embodiment acquires a plurality of pieces of information regarding the wearer's body shape from the user terminal T of the user U. The management apparatus 1 maps the acquired information into a multi-dimensional feature space having the plurality of features as coordinate axes, where the plurality of features correspond to the acquired information.
In this manner, any one point in the feature space corresponds to the wearer's body shape on a one-to-one basis. The management apparatus 1 maps information acquired from a plurality of different users U to the feature space, thereby forming a heat map indicating the distribution of the body shapes of the users U in the multi-dimensional space. A region having a high density of the distribution of the body shapes of the users U in the multi-dimensional space can be considered to mean that there is a great demand for the product having a size corresponding to this region.
In addition, the management apparatus 1 allocates, to each of a plurality of different points in the feature space, manufacturing data used for manufacturing the product corresponding to each region including coordinates of each of these points. Here, the “manufacturing data” is data for the manufacturing apparatus 3 to refer to in order to manufacture a product having a size fitting the body shape corresponding to the point to which the manufacturing data is allocated. In a case where the manufacturing apparatus 3 is a seamless knitting machine, for example, the “manufacturing data” is knitting data for the manufacturing apparatus 3 to refer to in order to knit the product having the size fitting the body shape corresponding to the point to which the manufacturing data is allocated.
The product manufactured by using the manufacturing data allocated to a certain point can be said to be a product that only fits the body shape corresponding to that point, theoretically. Actually, however, due to errors and variations in manufacturing of the product, physical fluctuations such as expansion and contraction of the raw material, and subjective fluctuations such as preferences of the wearer, the product manufactured according to the manufacturing data allocated to the certain point becomes a product corresponding to the size corresponding to the region including said certain point in the multi-dimensional space.
Therefore, the management apparatus 1 according to the embodiment calculates, on the basis of the density in the heat map indicating the distribution of the body shapes of the users U mapped to the regions in the feature space including the points to which the respective pieces of manufacturing data are allocated, the number of products to be manufactured using the respective pieces of manufacturing data. As a result, the management apparatus 1 can balance the variation in size of the product and the inventory risk. In other words, even if the number of pieces of manufacturing data arranged in the feature space is increased in order to increase the variation of details of the product, the number of each product to be manufactured according to each piece of the manufacturing data can be accurately estimated, and therefore, the inventory risk can be reduced.
Hereinafter, the management apparatus 1 according to the embodiment will be described in more detail.
The storage part 10 is a large-capacity storage device such as a read only memory (ROM) that stores a basic input output system (BIOS) of a computer that realizes the management apparatus 1, a random access memory (RAM) that becomes a working area of the management apparatus 1, and a hard disk drive (HDD) or a solid state drive (SSD) that stores an operating system (OS), an application program, or various kinds of information that is referred to when the application program is executed.
The control part 20 is a processor such as a CPU and a GPU of the management apparatus 1, and functions as a feature acquisition part 21, a mapping part 22, a manufacturing data allocation part 23, a region determination part 24, a production management part 25, and an order reception part 26 by executing programs stored in the storage part 10.
The feature acquisition part 21 acquires a plurality of features relating to the user U's body shape from the user terminal T of the user U via the network N. The mapping part 22 maps and superimposes, for each of a plurality of different users, a density distribution specified by the features of the plurality of different users on the multi-dimensional feature space having the plurality of features as the coordinate axes.
As described referring to
The mapping part 22 estimates, on the basis of the feature of the information that has been acquired, a value of a feature of information that has not been acquired among the plurality of features relating to the user U's body shape. For example, in
More specifically, the mapping part 22 calculates the average value μl and the variance al of the feature 1 of the other users U whose feature 2 values are F2, and treats a normal distribution specified by the average value μl and the variance al as the density distribution. Therefore, as shown in
For convenience of illustration,
For example, it is assumed that the feature 1 is the body fat percentage and the feature 2 is the weight. It is also assumed that the user U has also inputted information concerning height, gender, and age. In this instance, the mapping part 22 may generate the density distribution by calculating the average value μl and the variance al of the body fat percentage of the other users U having the same height, weight, gender, and age as those inputted by the user U and use the average value μl as an estimated value.
As described above, the source information can be considered to be information indicating the reliability of the feature. For example, a feature obtained from a salesperson of a store “measuring” the user U can be said to be highly reliable information. On the contrary, a feature, for which no value is inputted by the user U, obtained by “estimation” based on other features can be said to be information that is slightly less reliable than that obtained by “measurement.”
In addition, a feature that is once inputted by the user U and then fed back by the user U can also be said to be highly reliable information. The reliability of the feature is greatly improved if the feature obtained by the “estimation” is inputted by the feedback of the user U.
Therefore, the feature acquisition part 21 acquires the feature as well as the source information indicating the source of the feature relating to the body shape. The mapping part 22 changes, on the basis of the source of the feature, the shape of the density distribution specified by the feature in the feature space. This makes it possible to reflect the unreliability based on the source of the feature in the shape of the density distribution in the feature space.
Returning to the description of
The region determination part 24 determines, on the basis of the coordinates of each of the plurality of different points in the feature space, the region corresponding to the product to be manufactured on the basis of respective pieces of the manufacturing data allocated to the plurality of different points.
In
In
As described above, the region determination part 24 determines each region on the basis of the coordinates of each point to which the manufacturing data is allocated in the feature space. In the example shown in
In
Therefore, the production management part 25 calculates the number of products to be manufactured using the each piece of manufacturing data on the basis of the coordinates of each of the plurality of different points in the feature space and the density distribution mapped to and superimposed on the feature space. More specifically, the production management part 25 increases the number of products to be manufactured using the manufacturing data allocated to the region as the density of the superimposed density distribution included in the region increases. As a result, the production management part 25 can calculate the production quantity in accordance with the actual demand.
Here, the production management part 25 may calculate the production quantity in consideration of not only the density distribution in the feature space, but also the sales performance of the products in the past.
A manufacturing data identifier for uniquely specifying the manufacturing data is assigned to each piece of the manufacturing data. In the sales performance database, a density, which is the integrated value of the density distribution, and the annual sales are associated with each manufacturing data identifier. For example, the integrated value of the density distribution in the region to which the manufacturing data identifier 0001 is assigned is D1, and the annual sales are S1. The production management part 25 may reference the sales performance database and increase the number of products to be manufactured using the manufacturing data as the sales of the product manufactured on the basis of the manufacturing data become larger.
Specifically, when the integrated value of the density distribution in the region to which certain manufacturing data is allocated is D and the annual sales are S, the production management part 25 calculates the quantity of production P as P=axDx S. Here, a is a proportionality coefficient referenced by the production management part 25 for calculating the quantity of production P. The specific value of a may be determined in consideration of the production capacity and the like of the manufacturing apparatus 3. As is clear from the derivation equation of the quantity of production P, the larger the integrated value D of the density distribution in the region to which the certain manufacturing data is allocated, the larger the quantity of production P. In addition, the larger the past sales of the product manufactured using the certain manufacturing data, the larger the quantity of production P.
Here, the order reception part 26 receives an order for the product from the user U. The production management part 25 accumulates the number of orders received by the order reception part 26 on a yearly basis, thereby obtaining past sales of the product manufactured using the certain manufacturing data.
Generally, the number of orders for the product, such as a garment and shoes, is not uniform throughout the year. For example, the number of orders for sweaters and cardigans increases at the beginning of autumn and winter, and then returns to normal, but increases again in early spring. Therefore, the operation rate of the manufacturing apparatus 3 is not uniform throughout the year, and there is a busy period and a quiet period.
Accordingly, the production management part 25 calculates the quantity of production P, which is the number of products to be manufactured by the manufacturing apparatus 3, if the number of orders for the product received by the order reception part 26 is less than the manufacturing capacity of the manufacturing apparatus 3. As a result, the manufacturing apparatus 3 can manufacture the product that is expected to be sold at a time when there is a margin in the manufacturing capacity and hold them as inventory. Since the inventory held in advance can be sold during the busy period in which the number of orders exceeds the manufacturing capacity of the manufacturing apparatus 3, it is possible to suppress missing a sales opportunity. Further, the operation rate of the manufacturing apparatus 3 can be leveled, and therefore the manager of the production factory F can improve the efficiency of capital investment.
The case where the production management part 25 calculates the quantity of production on the basis of the density distribution mapped in the multi-dimensional feature space having the plurality of features as the coordinate axes has been described above. Here, the density distribution that the production management part 25 uses as a basis for calculating the quantity of production changes every time a feature is inputted or updated by the user U.
Therefore, the region determination part 24 may reorganize the region, which is the scope of the manufacturing data, after the density distribution is updated. Specifically, the region determination part 24 updates the region corresponding to the product to be manufactured on the basis of each of the plurality of pieces of manufacturing data in response to the update of the superimposed density distribution included in the region. Hereinafter, the reorganization of the region by the region determination part 24 will be described.
The integration part 240 integrates a plurality of regions into one region if the density of the superimposed density distribution included in the regions is less than the predetermined first threshold value. For example, the density distribution based on the body shape information of a certain user changes when the user U provides the feedback regarding the feature. If there is a change in the density distribution for a plurality of users U, the density distribution in the feature space also changes as a result.
If the body shape of the user U deviates from the average value, such as when the user U is a large person, the density of the feature space corresponding to the body shape of said user U is low. A change in the density distribution of such a user U may cause the density of the superimposed density distribution in the peripheral region to fall below the predetermined first threshold value. The product corresponding to such a region can be said to be a product with low demand from the beginning.
Therefore, from the standpoint of inventory risk management, the integration part 240 integrates regions covering the products with low demand. In this sense, the “first threshold value” is an “integration determination criterion density” that the integration part 240 references in order to determine whether or not to integrate the plurality of regions. The integration determination criterion density may be determined in consideration of the sales performances and the like of the products corresponding to the regions before integration.
As shown in
More specifically, the integration part 240 first makes a determination to integrate the region XL and the region XL2. Upon receiving the determination of the integration part 240, the manufacturing data allocation part 23 sets the midpoint between a point XL and a point XL2 as a point XL′ to which new manufacturing data is allocated, and deletes the point XL and the point XL2. The integration part 240 performs the Voronoi tessellation using the new point as a kernel point. As a result, the region XL and the region XL2 are integrated to generate the new region XL′. As shown in
Accordingly, the manufacturing data allocation part 23 can allocate new manufacturing data having the region integrated by the integration part 240 as the scope. Although the satisfaction level of the user U with respect to the product may be lowered because the region of the manufacturing data is widened, the product corresponding to the region integrated by the integration part 240 can be said to be a product with low demand from the beginning. Therefore, the integration part 240 can reduce the inventory risk by integrating the regions.
The division part 241 divides a region into two regions if the density of the superimposed density distribution included in the region exceeds the predetermined second threshold value. For example, the density of the region corresponding to the M-size body shape is high. When the order reception part 26 receives an order from a new user U, the body shape of the user U has a high probability of being M-size, and as a result, the density of the region corresponding to the M-size body shape may increase with time.
Here, since the manufacturing data is associated with one point in the feature space, the product manufactured by using each piece of the manufacturing data best matches the body shape corresponding to the point associated with the manufacturing data. Therefore, it is considered that the smaller the region in which the manufacturing data is used for manufacturing of the product corresponding thereto, the higher the satisfaction level of the user U who purchases the product corresponding to the region.
Hence, if the density of the superimposed density distribution included in a region exceeds the predetermined second threshold value, the division part 241 divides this region into two regions, thereby increasing the degree of customer satisfaction for the product manufactured by the manufacturing apparatus 3. In addition, since the division part 241 divides a region having density exceeding the second threshold value, it is ensured that the density of this region after the division is equal to or higher than a certain value. As a result, the inventory risk can be reduced.
Accordingly, the “second threshold value” is a “division determination criterion density” which the division part 241 refers to in order to determine whether or not to divide a region. The division determination criterion density may be determined in consideration of the sales performances and the like of the product corresponding to each region after the division.
As shown in
More specifically, the division part 241 first makes a determination to divide the region M. The manufacturing data allocation part 23 receives the determination of the division part 241, allocates new manufacturing data to new points MS and ML in the region M, and deletes a point M. The division part 241 performs the Voronoi tessellation with the new points as kernel points. As a result, the region M is divided into two regions, which are the region MS and the region ML. As shown in
The modification part 242 modifies at least one of the position, size, and shape of each region on the basis of the density of the superimposed density distribution included in the region. For example, in the example shown in
In such a case, the modification part 242 moves the point M to the region with the highest density. Therefore, the result of the Voronoi tessellation is also changed, and as a result, the position, size, or shape of each region is also changed.
As shown in
More specifically, the modification part 242 first makes a determination to modify the region M. The manufacturing data allocation part 23 moves the point M in response to the determination of the modification part 242. The modification part 242 performs the Voronoi tessellation using the new point as a kernel point. As a result, the sizes and shapes of the region M and the regions S1, M2, L, L1, M1, and S adjoining the region M are also changed. Since the point to which the manufacturing data is allocated is moved to the region having high density, the degree of customer satisfaction for the product can be increased. Further, it is also possible to manufacture, while the operation rate of the manufacturing apparatus 3 is low, a product that is expected to be demanded.
The feature acquisition part 21 acquires the plurality of features relating to the user U's body shape from the user terminal T of the user U via the network N (step S2). The mapping part 22 maps the density distribution specified by the feature acquired by the feature acquisition part 21 to the multi-dimensional feature space having the plurality of features as the coordinate axes (step S4).
The manufacturing data allocation part 23 allocates, to each of the plurality of different points in the multi-dimensional feature space, the manufacturing data used for manufacturing the product corresponding to each region including the coordinates of each point (step S6). The region determination part 24 determines the region in the feature space corresponding to the product to be manufactured by using each piece of the manufacturing data allocated to each point in the feature space (step S8).
The production management part 25 calculates the number of products to be manufactured using each piece of the manufacturing data on the basis of the density distribution in the region in which the manufacturing data allocated to each point in the feature space is used for manufacturing of the product corresponding thereto (step S10). After the production management part 25 calculates the number of products, the processing in this flowchart ends.
As described above, according to the management apparatus 1 according to the embodiment, it is possible to balance the variation in size of the product and the inventory risk.
In particular, since the production management part 25 calculates the quantity of production of the product on the basis of the density distribution superimposed on the feature space, potential demand can be reflected in the quantity of production. As a result, the inventory risk of products can be reduced.
In addition, the region determination part 24 determines, on the basis of the position coordinates of the plurality of pieces of manufacturing data arranged at each point in the feature space, the region in the feature space in which each piece of the manufacturing data is used for manufacturing of the product corresponding thereto, and therefore the manufacturing apparatus 3 can manufacture the product having a size closest to the size of the user U.
The production management part 25 increases the number of products to be manufactured corresponding to the region as the density of the region is higher and the past sales becomes greater. As a result, the production management part 25 can provide information for formulating a production plan of the product that meets actual demand.
When the density distribution is updated in the feature space, the region determination part 24 reorganizes the regions covered by each piece of manufacturing data. As a result, the production management part 25 can calculate the quantity of production while adapting the product that the production factory F manufactures to the variations of the body shapes of the users U.
The present invention is explained on the basis of the exemplary embodiments. The technical scope of the present invention is not limited to the scope explained in the above embodiments and it is possible to make various changes and modifications within the scope of the invention. For example, the specific embodiments of the distribution and integration of the apparatus are not limited to the above embodiments, all or part thereof, can be configured with any unit which is functionally or physically dispersed or integrated. Further, new exemplary embodiments generated by arbitrary combinations of them are included in the exemplary embodiments of the present invention. Further, effects of the new exemplary embodiments brought by the combinations also have the effects of the original exemplary embodiments.
In the above description, the region determination part 24 is described mainly as determining each region by using the Voronoi tessellation in which the coordinates of each point to which the manufacturing data is allocated are used as a kernel point in the feature space. Alternatively, the region determination part 24 may set each region as a super-rectangular parallelepiped in the dimensionality of the feature space. In this instance, the region determination part 24 may arrange each super-rectangular parallelepiped in such a manner that each super-rectangular parallelepiped always includes one point to which manufacturing data is allocated, and the region to which the density distribution is mapped in the feature space is dense with a plurality of super-rectangular parallelepipeds.
