[0007] Hereinafter, embodiments 1 to 3 embodying one embodiment of the present disclosure will be described in detail with reference to the drawings. The same or equivalent components, members, and processes shown in each drawing will be denoted by the same reference numerals, and redundant descriptions will be omitted as appropriate.

[0008] [Embodiment 1] [Overview] First, an overview of the production management device 1 according to this embodiment will be described. The production management device 1 acquires production quantities from production equipment 110, and calculates and displays the production capacity of the production equipment 110 from the acquired production quantities. Because the production capacity of the production equipment 110 is calculated from the actual production quantity, it is possible to calculate an appropriate production capacity without considering variable factors that may affect the production quantity.

[0009] The production facility 110 produces products such as ceramic manufactured products from raw materials such as ceramic. The production facility 110 also counts the production quantity of the produced products and transmits it to the production management device 1. For example, the production facility 110 may transmit the production quantity counted up to that point to the production management device 1 at predetermined time intervals. The predetermined time may be, for example, several seconds to several tens of seconds.

[0010] [Production Management Device 1] The production management device 1 will be described with reference to Fig. 1. Fig. 1 is a functional block diagram showing an overview of the production management device 1. As shown in Fig. 1, the production management device 1 includes a control unit 10, a storage unit 20, a communication unit 30, a display 40, and an operation unit 50.

[0011] The communication unit 30 communicates with external devices and receives the production quantity from the production equipment 110. The communication unit 30 then outputs the received production quantity to the control unit 10. The production quantity may be received periodically.

[0012] The control unit 10 executes processing in the production management device 1, and includes a first acquisition unit 11, a setting unit 12, a first calculation unit 13, a second calculation unit 14, a first display unit 15, and a timer 16. The storage unit 20 includes production quantity information 21, production capacity information 22, and first frequency information 23.

[0013] The first acquisition unit 11 acquires the production quantity M of the product for each first time T of the production equipment 110 from the production quantity acquired via the communication unit 30. For example, the first acquisition unit 11 acquires the production quantity M by counting the production quantity acquired via the communication unit 30 for the first time T. Then, the first acquisition unit 11 stores the production quantity M together with the acquisition time as production quantity information 21 in the storage unit 20. The first time T is, for example, several minutes to one hour. An example of the production quantity information 21 is shown in 201 of FIG. 2. In this example, the first time T is one minute, and the production quantity for each minute from 09:00 is shown. The first time T is also denoted in chronological order as Ta, Tb, Tc, etc. For example, the production quantity from 09:00 to 09:01 (Ta) is Ma (units), the production quantity from 09:01 to 09:02 (Tb) is Mb (units), and the production quantity from 09:02 to 09:03 (Tc) is Mc (units), etc.

[0014] The setting unit 12 sets a standard production quantity MK for a predetermined period S. Specifically, the setting unit 12 sets the standard production quantity MK using the production quantity M for each first time T in the period S stored in the production quantity information 21 of the storage unit 20. Then, the setting unit 12 stores the set standard production quantity MK in the storage unit 20. For example, the setting unit 12 sets a flag indicating that the production quantity M in the production quantity information 21 is the standard production quantity MK (indicated by a "◯" in 201 in FIG. 2 ), thereby storing the fact that the production quantity M is the standard production quantity MK.

[0015] A more detailed explanation will be given below with reference to Fig. 3. Fig. 3 is a diagram showing the transition of the production quantity M for each first time T in a period S.

[0016] 3, the first time T in the period S is chronologically represented as Ta, Tb, Tc, Td, Te, Tf, Tg, Th, and Ti. The production quantity at Ta is represented as Ma, the production quantity at Tb as Mb, the production quantity at Tc as Mc, the production quantity at Td as Md, and the production quantity at Te as Me. The production quantity at Tf is represented as Mf, the production quantity at Tg as Mg, the production quantity at Th as Mh, and the production quantity at Ti as Mi.

[0017] Here, it is assumed that the largest production quantity among the production quantities Ma to Mi in the period S is Mf ( FIG. 3 ). In this case, the setting unit 12 sets Mf, which is the largest production quantity in the period S, as the standard production quantity MK. Then, the setting unit 12 stores the set standard production quantity MK in the storage unit 20.

[0018] The standard production quantity MK does not necessarily have to be the maximum production quantity. For example, the setting unit 12 may set the second largest production quantity Mg among the production quantities M in the period S as the standard production quantity MK. Furthermore, the setting unit 12 may set the average value of the production quantities M in the period S, that is, (Ma + Mb + Mc + Md + Me + Mf + Mg + Mh + Mi) / 9 as the standard production quantity MK.

[0019] The first calculation unit 13 uses the standard production quantity MK in the period S and the production quantity M for each first hour T to calculate the production capacity P (%) of the production facility 110 for each first hour T in the period S. Specifically, the first calculation unit 13 calculates the production capacity P using the formula P = M / MK × 100.

[0020] Explaining this using the example of FIG. 3 , the first calculation unit 13 calculates the production capacity Pa at the first time Ta as Pa = Ma / MK × 100. The first calculation unit 13 also calculates the production capacity Pb ​​at the first time Tb as Pb = Mb / MK × 100. Thereafter, the first calculation unit 13 calculates the production capacity P at each first time T, for example, calculating the production capacity Pc at the first time Tc as Pc = Mc / MK × 100. Therefore, for example, if the maximum production quantity is the base production quantity MK, the production capacity P at each time is expressed as a percentage (%) of the maximum production quantity for the period S. Then, the first calculation unit 13 stores the calculated production capacity P over time in the storage unit 20 as production capacity information 22 (201 in FIG. 2 ).

[0021] The second calculation unit 14 calculates a first frequency, which is the frequency of the production capacity P of the production equipment 110 for each first time T during a period S. For example, assume that the production capacity P at each first time T during a certain period S is "80, 80, 90, 100, 90, 90, 90, 70, 60, 70." In this case, the second calculation unit 14 calculates the first frequencies as follows: the frequency of a production capacity P of "100" is "1," the frequency of a production capacity P of "90" is "4," the frequency of a production capacity P of "80" is "2," the frequency of a production capacity P of "70" is "2," and the frequency of a production capacity P of "60" is "1." Then, the second calculation unit 14 stores the first frequencies together with the production capacity P as first frequency information 23 in the storage unit 20. An example of the first frequency information 23 is shown in 202 of FIG. 2 .

[0022] The first display unit 15 creates a first graph G1 that shows the relationship between the production capacity P and the first frequency for each first time T. Then, the first display unit 15 displays the first graph G1 on the display 40.

[0023] 4 to 6 show examples of the shape of the first graph G1 that the first display unit 15 displays on the display 40. FIG. 4 is a diagram showing a graph G11, which is an example of the first graph G1. FIG. 5 is a diagram showing a graph G12, which is an example of the first graph G1. FIG. 6 is a diagram showing a graph G13, which is an example of the first graph G1. All of the graphs G11 to G13 are graphs in which the horizontal axis represents production capacity P and the vertical axis represents the first frequency.

[0024] Graph G11 shown in FIG. 4 has a peak of the first frequency when production capacity P is close to "100," and has a shape that is narrow in the horizontal direction and protrudes upward. When production capacity P is close to "100," the production facility 110 is operating at almost full capacity. Therefore, when the first graph G1 has such a shape, it indicates that the operation rate of the production facility 110 is high. Therefore, the manager of the production facility 110 can easily confirm that the operation rate of the production facility 110 is high from graph G11 displayed on the display 40.

[0025] Graph G12 shown in FIG. 5 has a first frequency peak near the average value of production capacity P, and the width of the horizontal axis of production capacity P is wide, with production capacity P extending to both "0" and "100." A production capacity P close to "0" indicates that the production equipment 110 is not operating. Furthermore, a production capacity P peaking near the average value indicates that a state in which the production equipment 110 is unable to operate at full capacity has occurred and that this state continues. Therefore, when the first graph G1 has this shape, there is a possibility that the production equipment 110 is repeatedly temporarily stopped due to the same cause. Therefore, the manager of the production equipment 110 can easily confirm from graph G12 displayed on the display 40 that temporary stoppages due to the same cause may be occurring repeatedly during production by the production equipment 110.

[0026] Graph G13 shown in FIG. 6 shows a shape in which the first frequency drops near the average value of production capacity P and peaks in the first frequency on both sides of the average value along the horizontal axis. Graph G13 also shows a shape in which the width of the horizontal axis is wide, with production capacity P extending to both "0" and "100." The fact that production capacity P has multiple peaks other than "100" indicates that the production equipment 110 is unable to operate at full capacity due to multiple causes and that this condition continues. Therefore, when the first graph G1 has this shape, it is possible that the production equipment 110 is continually experiencing temporary shutdowns and that there are multiple causes. Therefore, the manager of the production equipment 110 can easily confirm from graph G13 displayed on the display 40 that the production equipment 110 is continually experiencing temporary shutdowns and that there are multiple causes.

[0027] The timer 16 measures time and outputs date and time information to the setting unit 12.

[0028] The display 40 is a display device that displays information, such as a liquid crystal display, an organic EL (Electro-Luminescence) display, etc. The operation unit 50 accepts user operations on the production management device 1, such as a keyboard or a mouse. The display 40 and operation unit 50 may also be integrated into one device, such as a touch panel.

[0029] [Processing Flow of Production Management Device 1] Next, the processing flow executed by the control unit 10 of the production management device 1 configured as above will be described with reference to Fig. 7. Fig. 7 is a flowchart showing an example of the processing flow in the production management device 1.

[0030] 7 , in the control unit 10, first, the first acquisition unit 11 starts measuring time using the timer 16 (S11). Then, the first acquisition unit 11 acquires the production quantity M at the first time T from the production quantity produced by the production equipment 110 input from the communication unit 30 (S12, acquisition step). Then, the first acquisition unit 11 stores the production quantity M in the storage unit 20 as production quantity information 21 (S13, storage step).

[0031] Next, the setting unit 12 determines whether it is time to evaluate the operating state of the production equipment 110 (S14). Whether it is time to evaluate the operating state is determined, for example, based on whether a period S has elapsed since the start of timekeeping. The period S may be, for example, one hour, eight hours, one day, one week, one month, or one year.

[0032] If the setting unit 12 determines that it is not time to evaluate the operating state of the production facility 110 (S14: NO), the setting unit 12 returns to the process of step S12 again. On the other hand, if the setting unit 12 determines that it is time to evaluate the operating state of the production facility 110 (S14: YES), the setting unit 12 proceeds to the process of step S15.

[0033] In step S15, the setting unit 12 sets a standard production quantity MK using the production quantity M (setting step). Then, the setting unit 12 stores the set standard production quantity MK in the storage unit 20 (S15).

[0034] Next, the second calculation unit 14 calculates a first frequency, which is the frequency at which the production capacity P appears (S16). Subsequently, the first display unit 15 generates a first graph G1 showing the relationship between each production capacity P and the first frequency, using each production capacity P and the first frequency associated with each production capacity P from the first frequency information 23 in the storage unit 20. Then, the first display unit 15 displays the first graph G1 on the display 40 (S17). Thereafter, the control unit 10 ends the process.

[0035] As described above, in the production management device 1 according to the first embodiment, the setting unit 12 sets the standard production quantity MK for the period S using multiple production quantities M of the product acquired for each first time T. The first calculation unit 13 then calculates the production capacity P for each first time T by dividing the production quantity M for each first time T by the set standard production quantity MK. This allows the manager to easily recognize the production capacity P of the production equipment 110 for each first time T. Furthermore, because the production capacity P is calculated using the actual production quantity M, it is possible to calculate the meaningful production capacity P of the production equipment 110 without considering the type of product, differences between lots, aging of the production equipment 110, and the like. Furthermore, using the production capacity P makes it possible to identify process issues and take measures, which can lead to improved productivity of the production equipment 110.

[0036] Furthermore, even if the lot or the equipment of the production facility 110 changes, the production capacity P can be calculated simply by measuring the production quantity M for each first time T, so that the production capacity P can be calculated easily and with a simple configuration.

[0037] [Embodiment 2] [Production management device 2] Next, a production management device 2 according to embodiment 2 will be described with reference to Fig. 8 to Fig. 11. First, the production management device 2 according to embodiment 2 will be described with reference to Fig. 8. Fig. 8 is a functional block diagram showing an overview of the production management device 2. The production management device 2 according to embodiment 2 differs from the production management device 1 according to embodiment 1 in the following respects.

[0038] 8 , the control unit 10 of the production management device 2 includes a third calculation unit 17, a fourth calculation unit 18, and a second display unit 19 instead of the first calculation unit 13, the second calculation unit 14, and the first display unit 15 of the production management device 1. The storage unit 20 of the production management device 2 includes cycle time information 24 and second frequency information 25 instead of the production capacity information 22 and the first frequency information 23 of the production management device 1.

[0039] As shown in FIG. 8 , the production management device 2 includes a control unit 10 , a storage unit 20 , a communication unit 30 , a display 40 , and an operation unit 50 .

[0040] The control unit 10 executes processing in the production management device 2, and includes a first acquisition unit 11, a setting unit 12, a third calculation unit 17, a fourth calculation unit 18, a second display unit 19, and a timer 16. The storage unit 20 includes production quantity information 21, cycle time information 24, and second frequency information 25.

[0041] The third calculation unit 17 calculates the cycle time Q for each first time T during the period S using the production quantity M. The cycle time Q is the time required to produce one product and is calculated using the formula Q (seconds) = T / M (units). If the first time T is measured in minutes or hours, it is converted to seconds for calculation. The cycle time Q may be the time required to produce a predetermined number of products. The third calculation unit 17 then stores the calculated cycle time Q together with time in the storage unit 20 as cycle time information 24 ( 901 in FIG. 9 ). The cycle time Q may be expressed as an integer by rounding up or down any decimal places in the calculation result, or may be expressed to one decimal place by rounding up or down any decimal places. Furthermore, the cycle time Q may be expressed to two decimal places by rounding up or down any decimal places.

[0042] The fourth calculation unit 18 calculates a second frequency, which is the frequency of the cycle time Q of the production equipment 110 for each first time T during the period S. For example, assume that the cycle times Q for each first time T during the period S are "9, 10, 9, 10, 11, 10, 11, 12, 10, 12, 13, 10, 11" seconds. In this case, the fourth calculation unit 18 calculates the second frequencies such that the frequency of a cycle time Q of "9" seconds is "2," the frequency of a cycle time Q of "10" seconds is "5," and the frequency of a cycle time Q of "11" seconds is "3." The fourth calculation unit 18 also calculates the second frequencies such that the frequency of a cycle time Q of "12" seconds is "2," and the frequency of a cycle time Q of "13" seconds is "1." Then, the fourth calculation unit 18 stores the second frequencies together with the cycle times Q in the storage unit 20 as second frequency information 25 (902 in FIG. 9 ).

[0043] The second display unit 19 creates a second graph G2 showing the relationship between the cycle time Q and the second frequency for each first time T. Then, the second display unit 19 displays the second graph G2 on the display 40.

[0044] The first acquisition unit 11 may also acquire information about lots of M production quantities produced by the production facility 110. Here, a lot is a unit for managing manufactured products. More specifically, a lot is the smallest unit of production quantity or shipping quantity of products manufactured under the same conditions. The number of items in one lot is not particularly determined, and may be, for example, 50 items or 100 items per lot.

[0045] The third calculation unit 17 may store the cycle time Q, which represents the operating state of the production equipment 110 for each first time T, for each lot in the storage unit 20 along with time as cycle time information 24. In this case, the fourth calculation unit 18 may read the cycle time Q for each lot from the cycle time information 24 in the storage unit 20, and calculate a second frequency, which is the frequency of each cycle time Q, for each lot. The fourth calculation unit 18 may store the second frequency for each lot together with the cycle time Q as second frequency information 25 in the storage unit 20.

[0046] 10 and 11 show examples of the second graph G2 displayed on the display 40 by the second display unit 19. Fig. 10 shows a graph G21, which is an example of the second graph G2. Fig. 11 shows graphs G22 and G23 for each lot, which are also examples of the second graph G2. Graphs G21 to G23 are graphs in which the horizontal axis represents the cycle time and the vertical axis represents the second frequency.

[0047] 10, the second frequency is highest when the cycle time Q is 10 seconds. As the cycle time Q becomes longer than 10 seconds, the second frequency gradually decreases. If the graph G21 extends to the right in the horizontal direction from the most frequent value of the cycle time Q, this indicates that there may be a problem with the production equipment 110, such as a capacitor malfunction.

[0048] This allows the manager of the production facility 110 to easily recognize the distribution of the cycle time Q of the production facility 110 from the shape of the graph G21 displayed on the display 40 and to discover any problems.

[0049] 11, the histogram graph G22 for lot #01 shows the highest second frequency of 2A [times] corresponding to a cycle time Q of 10 [seconds], while the histogram graph G23 for lot #02 shows the highest second frequency of 1A [times] corresponding to a cycle time Q of 20 [seconds].

[0050] By using the second frequency for each lot, it is also possible to calculate the cycle time Q including multiple lots. For example, the total cycle time Q for lot #01 and lot #02 shown in FIG. 11 can be calculated using the maximum value of the second frequency for each of lots #01 and #02 using the following formula (1): Q = ((10 x 2A) + (20 x 1A)) / (2A + 1A) (1) Furthermore, various values ​​totaling lot #01 and lot #02 can also be calculated using the average value of the second frequency for each of lots #01 and #02 or other representative values ​​(maximum value, minimum value, etc.).

[0051] [Processing Flow of Production Management Device 2] Next, the processing flow executed by the control unit 10 of the production management device 2 configured as above will be described with reference to Fig. 12. Fig. 12 is a flowchart showing an example of the processing flow in the production management device 2.

[0052] 12, the processes of steps S11 to S14 are the same as those in the above-described embodiment 1 (see FIG. 7). If the setting unit 12 determines in step S14 that it is time to evaluate the operating state of the production equipment 110 (S14: YES), the setting unit 12 proceeds to the process of step S21.

[0053] In step S21, the fourth calculation unit 18 calculates a second frequency, which is the frequency at which each cycle time Q occurs. Subsequently, the second display unit 19 reads out each cycle time Q and the second frequency associated with each cycle time Q from the second frequency information 25 in the storage unit 20. Then, the second display unit 19 generates a histogram-like second graph G2 indicating the relationship between each cycle time Q and the second frequency, and displays it on the display 40 (S22). Thereafter, the control unit 10 ends this process.

[0054] As described above, in the production management device 2 according to the second embodiment, the second display unit 19 generates the second graph G2 in the form of a histogram indicating the relationship between each cycle time Q and the second frequency. Then, the second display unit 19 displays the second graph G2 on the display 40.

[0055] This allows the manager of the production facility 110 to easily recognize the distribution of the cycle time Q of the production facility 110 from the second graph G2 displayed on the display 40. Furthermore, the manager of the production facility 110 can infer the operating status of the production facility 110 from the second graph G2 displayed on the display 40, which in turn can lead to an improvement in the productivity of the production facility 110.

[0056] [Embodiment 3] [Production management device 3] Next, a production management device 3 according to embodiment 3 will be described with reference to Fig. 13. The production management device 3 according to embodiment 3 will be described with reference to Fig. 13. Fig. 13 is a functional block diagram showing an overview of the production management device 3. The production management device 3 according to embodiment 3 has features of both the production management device 1 according to embodiment 1 and the production management device 2 according to embodiment 2.

[0057] 13 , the control unit 10 of the production management device 3 includes a first acquisition unit 11, a setting unit 12, a first calculation unit 13, a second calculation unit 14, a first display unit 15, a timer 16, a third calculation unit 17, a fourth calculation unit 18, and a second display unit 19. The storage unit 20 of the production management device 3 includes production quantity information 21, production capacity information 22, first frequency information 23, cycle time information 24, and second frequency information 25.

[0058] As a result, the production management device 3 can calculate the production capacity P described in the first embodiment, and can also calculate the cycle time Q described in the second embodiment.

[0059] [Example of implementation by software] The functions of each production management device 1 to 3 (hereinafter referred to as "device") can be realized by a program that causes a computer to function as the device, and a program that causes a computer to function as each control block of the device (especially each part included in the control unit 10).

[0060] In this case, the device includes a computer having at least one control device (e.g., a processor) and at least one storage device (e.g., a memory) as hardware for executing the program.

[0061] The program may be non-transitory and may be recorded on one or more computer-readable recording media. The recording media may or may not be included in the device. In the latter case, the program may be supplied to the device via any wired or wireless transmission medium.

[0062] In addition, some or all of the functions of each of the control blocks can be realized by logic circuits. For example, integrated circuits in which logic circuits that function as each of the control blocks are formed are also included in the scope of the present disclosure. In addition, the functions of each of the control blocks can also be realized by, for example, a quantum computer.
