[0003] [Patent Document 1] Japanese Patent Application Publication No. 2024-9711 Summary of the Invention [Problem to be solved by the invention]

[0004] At production sites, a production system is sometimes used in which production equipment, workers, and mobile objects such as automatic conveyance devices each play their respective roles and work together to carry out production work. In this production system, for example, the production equipment automatically processes materials and assembles products, while the mobile objects appropriately handle the attachment and removal of materials, and the production work progresses through a division of labor.

[0005] The technology disclosed in Patent Document 1 is a technology that improves production efficiency and achieves energy savings in production lines that automatically produce boards on which a large number of components are mounted, but it is not expected to be sufficiently effective in non-automated production lines in which the above-mentioned production equipment and mobile objects work together to carry out production work.

[0006] The present disclosure has been made in consideration of the circumstances described above, and aims to make it possible to improve production efficiency and reduce energy consumption in a production system in which production equipment and mobile objects work together to carry out production work.

The operation information acquisition means acquires operation information indicating the operation status of the production equipment. The location information acquisition means acquires location information indicating the location of a mobile object that can work in cooperation with the production equipment. The work status identification means identifies the work status of the production equipment and the mobile object based on the operation information and the location information. The instruction content determination means determines instruction contents for the production equipment and the mobile object according to the work status. The production equipment instruction information notification means notifies the production equipment of production equipment instruction information indicating instruction contents for the production equipment. The mobile object instruction information notification means notifies the mobile object of mobile object instruction information indicating instruction contents for the mobile object. [Effects of the Invention]

[0008] According to the present disclosure, the production management system identifies the work status of the production equipment and the mobile body based on the operation information of the production equipment and the location information of the mobile body, and notifies the production equipment instruction information indicating the instructions to the production equipment and the mobile body instruction information indicating the instructions to the mobile body, respectively. This makes it possible to improve production efficiency and reduce energy consumption in a production format in which the production equipment and the mobile body cooperate with each other to carry out production work.

[0010] A production management system, a production management device, a production management method, and a program according to an embodiment of the present disclosure will be described in detail below with reference to the drawings. The production management system according to the embodiment of the present disclosure manages production efficiency and energy efficiency.

[0011] 1, a production management system 1 according to an embodiment of the present disclosure includes at least one production management device 100 that manages the production of products, multiple production facilities 200a, 200b, 200c, ... 200x that produce the products, and multiple work support devices 300a, 300b, 300c, ... 300y that support the work of workers PWa, PWb, PWc, ... , PWy. Note that the letters following the production facilities 200, work support devices 300, and workers PW are given for convenience to identify each production facility 200, each work support device 300, and worker PW, and are unrelated to the number of production facilities 200 and work support devices 300.

[0012] In the following description, when there is no need to distinguish between the individual production equipment 200a, 200b, 200c, ..., 200x, they will be collectively referred to as production equipment 200. Furthermore, when there is no need to distinguish between the individual work support devices 300a, 300b, 300c, ..., 300y, they will be collectively referred to as work support devices 300. Similarly, when there is no need to distinguish between the individual workers PWa, PWb, PWc, ..., PWy, they will be collectively referred to as worker PW. Note that the corresponding workers PW and work support devices 300 have the same suffix, such as the work support device carried by worker PWa being work support device 300a, and the work support device carried by worker PWb being work support device 300b. Furthermore, in this embodiment, the production management system 1 is described as having a worker PW and a work support device 300 carried by the worker PW as mobile bodies, but the production management system 1 may have other mobile bodies, such as an automatic conveying device, instead of or in addition to the worker PW and the work support device 300.

[0013] The production management device 100 and the production facility 200 are communicably connected, for example, via a wired LAN (Local Area Network) conforming to the Ethernet (registered trademark) standard, a dedicated line, etc. The production management device 100 and the production facility 200 are communicably connected, for example, via a wireless LAN such as Wi-Fi (Wireless Fidelity) (registered trademark).

[0014] The production management device 100 is a general-purpose computer device such as a personal computer or a server computer, and manages the work status of workers PW and production equipment 200. The production management device 100 acquires operation information from each production equipment 200 and acquires location information from each work support device 300. Based on this acquired information, the production management device 100 identifies the work status of the production equipment 200 and workers PW, and instructs the operation mode that each production equipment 200 should perform and the work content that each worker PW should perform.

[0015] The production facility 200 is a production device that physically or scientifically processes and treats workpieces to be processed, and includes, for example, a processing device, a processing device, a conveying device, an inspection device, a control device, and the like. In this embodiment, the production facility 200 will be described using, as an example, a lathe that performs outer diameter processing, inner diameter processing, hole drilling, groove processing, and the like on workpieces. The production facility 200 has multiple operating modes with different energy consumption amounts, and operates by switching between the multiple operating modes in response to instructions from the production management device 100. The operating modes include, for example, a normal operating mode in which the facility operates with normal power consumption, and an energy-saving mode in which the facility operates with less power consumption than the normal operating mode.

[0016] The work support device 300 is a device that supports production work by a worker PW at a production site. The work support device 300 is a small device that the worker PW can carry while working, such as a wristwatch-type wearable device worn on the worker PW's wrist. The work support device 300 generates position information indicating the position of the worker PW at the production site and transmits it to the production management device 100. The work support device 300 receives beacon signals transmitted by beacons installed at the production site using a beacon sensor provided in the work support device 300, and generates position information for the worker PW by identifying the beacon closest to the worker PW based on the strength of the received signal. The position information represents the position of the worker PW using, for example, an XY Cartesian coordinate system on the floor or ceiling of the production site. In addition to the beacon sensor, the work support device 300 also includes an acceleration sensor, an azimuth angle sensor, and the like, and uses the detection data from these sensors to identify the position and movement of the worker PW. The work support device 300 displays the work instructions generated and transmitted by the production management device 100 on its own display screen based on this position information. The worker PW proceeds with the work according to the work instructions displayed on the display screen.

[0017] (Example of hardware configuration of production management device 100) Next, we will explain an example of the hardware configuration of the production management device 100. As shown in Fig. 2, the production management device 100 physically comprises a processor 101, a memory 102, a storage 103, a display device 104, an input / output interface (input / output I / F (InterFace)) 105, and a communication interface (communication I / F) 106. These components are electrically connected to each other via a bus line 107.

[0018] The processor 101 is an arithmetic device that controls the overall operation of the production management device 100. The processor 101 is a general-purpose processor such as a CPU (Central Processing Unit), an MPU (Micro Processing Unit), or a GPU (Graphics Processing Unit). The processor 101 is not limited to a general-purpose processor, and may be a dedicated processor configured using an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), or the like.

[0019] The memory 102 is a main storage device and includes a ROM (Read Only Memory), a RAM (Random Access Memory), etc. The processor 101 reads programs and various data from the ROM or storage 103 onto the RAM and executes the processes, thereby realizing the overall control and functions of the production management device 100.

[0020] The storage 103 is an auxiliary storage device that stores programs and various data required for program execution, and includes non-volatile storage devices such as HDDs (Hard Disk Drives) and SSDs (Solid State Drives). The storage 103 stores, for example, an OS (Operating System), which is basic software that controls the entire production management device 100, and applications that run on the OS and provide various functions. Note that some of the programs and various data required for program execution may be stored in ROM.

[0021] The display device 104 is an image display device such as an LCD (Liquid Crystal Display), a PDP (Plasma Display Panel), or an organic EL (Electro-Luminescence) display, and displays various images under the control of the processor 101. The display device 104 displays, for example, images related to production management processing on a display screen. The display device 104 may be connected to the input / output interface 105 for use.

[0022] The input / output interface (input / output I / F) 105 is an interface for connecting to input devices such as a keyboard and a mouse for inputting operation signals, and output devices such as a speaker for outputting audio data. The input / output interface 105 receives operation data input by an operator via the input device, and outputs data such as moving images and audio to the output device.

[0023] The communication interface (communication I / F) 106 is an interface that connects to a communication network and enables the production management device 100 to perform data communication with each of the production equipment 200 and the work support device 300. The communication interface 106 includes, for example, a network board, an Ethernet module that performs data communication with the production equipment 200, a wireless LAN module that performs data communication with the work support device 300, etc.

[0024] (Example of functional configuration of production management device 100) Next, we will explain the functional configuration of the production management device 100. As shown in Figure 3, the production management device 100 functionally comprises a control unit 110, a storage unit 120, a display unit 130, an input / output unit 140, and a communication unit 150.

[0025] The control unit 110 is realized, for example, by a process in which the processor 101 shown in Fig. 2 executes a program loaded from the storage 103 into the RAM of the memory 102. The storage unit 120 is realized, for example, by the memory 102 and storage 103 shown in Fig. 2. The input / output unit 140 is realized, for example, by the input / output interface 105 shown in Fig. 2. The communication unit 150 is realized, for example, by the communication interface 106 shown in Fig. 2.

[0026] The control unit 110 controls the overall functions of the production management device 100. The control unit 110 has an operation information acquisition unit 111 that acquires operation information of the production equipment 200, a location information acquisition unit 112 that acquires location information of the worker PW, a work status identification unit 113 that identifies the work status, an instruction content determination unit 114 that determines instruction content, a production equipment instruction information notification unit 115 that notifies the production equipment 200 of production equipment instruction information, and a worker instruction information notification unit 116 that notifies the worker PW of worker instruction information.

[0027] The operation information acquisition unit 111 acquires operation information indicating the operation status of the production facility 200. The operation information includes, for example, the operation status, operation time, operation settings, power consumption, etc. of the production facility 200. The operation information acquisition unit 111 acquires the operation information by, for example, transmitting a transmission request to the production facility 200 via the communication unit 150 to instruct the production facility 200 to transmit the operation information, and receiving the operation information transmitted from the production facility 200 in response to the transmission request. The operation information acquisition unit 111 is an example of operation information acquisition means.

[0028] The position information acquisition unit 112 acquires position information of the worker PW. The position information includes, for example, coordinate values ​​at the production site. The position information acquisition unit 112 acquires the position information of the worker PW, for example, by transmitting a transmission request to the work support device 300 via the communication unit 150 to instruct the transmission of position information, and receiving position information transmitted from the work support device 300 in response. Here, the position information transmitted from the work support device 300 indicates the position of the work support device 300 carried by the worker PW, but the position information acquisition unit 112 processes the position of the work support device 300 indicated by the position information acquired from the work support device 300 as the position of the worker PW. The position information acquisition unit 112 is an example of position information acquisition means.

[0029] The work status identification unit 113 identifies the work status of the production equipment 200 and the worker PW based on the operation information of the production equipment 200 and the location information of the worker PW. The work status identification unit 113 is an example of a work status identification means. The work status identification unit 113 identifies the work status of the production equipment 200 and the worker PW as, for example, "solo work," "team work," or "non-operation."

[0030] "Independent work" is work performed independently by the production equipment 200 and the worker PW. Independent work performed by the production equipment 200 includes, for example, outer diameter machining, inner diameter machining, drilling, and groove machining. Independent work performed by the worker PW includes measurement, inspection, and deburring. Deburring is the process of removing protrusions that occur on the workpiece during each process, such as cutting and molding, and parts that are difficult to remove by machine are mainly performed manually by the worker.

[0031] "Associated work" is work performed in cooperation between the production equipment 200 and the worker PW, and mainly corresponds to pre- and post-processing of various processes in the production equipment 200. "Associated work" includes, for example, the installation of a workpiece on the production equipment 200, removal of a workpiece from the production equipment 200, replacement of cutting tools, and supply of cutting water by the worker PW.

[0032] "Non-operation" refers to a situation in which no production activity is being carried out. Non-operation by the production equipment 200 corresponds to, for example, situations in which no processing work is being performed by the production equipment 200 except for the time required for pre- and post-processing of various processes, or an abnormal stop in which processing is interrupted due to some kind of malfunction. Non-operation by a worker PW corresponds to, for example, a so-called waiting state in which the worker PW has no work to perform and is waiting for the next work. Note that a worker PW taking a rest during a preset time does not constitute non-operation by the worker PW.

[0033] The work status identification unit 113, for example, refers to the production equipment work status identification table shown in Fig. 4 and identifies the work status of the production equipment 200 based on the "production equipment work status" associated with the combination of "production equipment operation status" corresponding to the operation status included in the operation information of the production equipment 200 and "worker location" corresponding to the location of the worker PW indicated by the location information. In the production equipment work status identification table shown in Fig. 4, for example, "production equipment work status: solo work" is associated with the combination of "production equipment operation status: external diameter processing, internal diameter processing, etc." and "worker location: workbench, checkroom, etc."

[0034] Furthermore, the work status identification unit 113, for example, refers to the worker work status identification table shown in Fig. 5 and identifies the work status of the worker PW based on the "worker work status" associated with the "worker location" and the "production equipment operation status." In the worker work status identification table shown in Fig. 5, for example, the combination of "worker location: near production equipment" and "production equipment operation status: workpiece installation, workpiece removal, cutting water supply, etc." is associated with "worker work status: collaborative work." Note that the worker work status identification table shown in Fig. 5 is associated with "worker work content" that indicates the specific work content of the worker PW estimated from the combination of the "worker location" and the "production equipment operation status."

[0035] Returning to FIG. 3 , the instruction content determination unit 114 determines the instruction content for the worker PW and the production facility 200 based on predetermined conditions. For example, when the work status of the worker PW identified by the work status identification unit 113 satisfies the condition that the worker PW is not in operation, the instruction content determination unit 114 determines the work to be performed by this worker PW. The instruction content determination unit 114 is an example of an instruction content determination means. For example, the instruction content determination unit 114 determines to instruct the worker PW to perform an individual task such as inspecting and testing the production facility 200 or measuring a machined workpiece, or a combined task such as removing a machined workpiece from the production facility 200 after various types of processing have been completed and attaching a workpiece to be processed.

[0036] In addition, for example, when the work status of the worker PW and the production equipment 200 identified by the work status identification unit 113 both meet the condition that they are not operating, the instruction content determination unit 114 decides to instruct the non-operating production equipment 200 to switch its operating mode to an energy-saving mode.

[0037] The production equipment instruction information notification unit 115 notifies the production equipment 200 of the production equipment instruction information. The production equipment instruction information notification unit 115 transmits the production equipment instruction information indicating the instruction content determined by the instruction content determination unit 114 to the corresponding production equipment 200 via the communication unit 150. The production equipment 200 that receives the production equipment instruction information instructing it to switch to the energy saving mode switches its operation mode from the normal mode to the energy saving mode. Note that the operation mode can be switched from the energy saving mode to the normal mode in response to, for example, input of an operation signal by the operator PW instructing the start of a processing operation. Note that the production equipment instruction information notification unit 115 is an example of a production equipment instruction information notification means.

[0038] The worker instruction information notification unit 116 notifies the worker PW of the worker instruction information. The worker instruction information notification unit 116 transmits the worker instruction information indicating the instruction content determined by the instruction content determination unit 114 to the corresponding work support device 300 via the communication unit 150. The worker PW performs work in accordance with the instruction content displayed on the display screen of the work support device 300. Note that the worker instruction information is an example of mobile object instruction information. Also, the worker instruction information notification unit 116 is an example of mobile object instruction information notification means.

[0039] The memory unit 120 stores various data and control programs executed by the control unit 110. The memory unit 120 stores, for example, the production equipment work status identification table and the worker work status identification table described above. The display unit 130 displays various information under the control of the control unit 110. The input / output unit 140 inputs various data from an input device and outputs various data to an output device under the control of the control unit 110. The communication unit 150 transmits and receives various data to and from the production equipment 200 and the work support device 300 under the control of the control unit 110.

[0040] (Example of functional configuration of production equipment 200) Next, an example of the functional configuration of the production equipment 200 will be described with reference to Fig. 6. Fig. 6 shows components for switching the operation mode when the production equipment 200 executes a workpiece machining operation. The production equipment 200 includes a control unit 210, a machining unit 220, and a communication unit 230.

[0041] The control unit 210 is realized by a processor and a memory, and controls the overall functions of the production equipment 200. The control unit 210 performs, for example, generating operation information indicating the operating status of the machining units, controlling switching of the operation modes of the machining units, and the like.

[0042] The machining unit 220 is a machine mechanism that performs various machining operations on a workpiece. The machining unit 220 operates by switching the operation mode under the control of the control unit 210.

[0043] The communication unit 230 is realized by a communication module for communicating with the production facility 200 via Ethernet (registered trademark), a dedicated line, etc. The communication unit 230, for example, transmits operation information of the production facility 200 generated by the control unit 210 to the production management device 100, and receives production facility instruction information from the production management device 100 that instructs switching to an operation mode.

[0044] (Example of functional configuration of work support device 300) Next, an example of the functional configuration of the work assistance device 300 will be described with reference to Fig. 7. The work assistance device 300 includes a control unit 310, a detection unit 320, a display unit 330, an input / output unit 340, and a communication unit 350.

[0045] The control unit 310 is realized by a processor and a memory, and controls the overall functions of the work support device 300. The control unit 310, for example, identifies the position of the worker PW using detection data detected by the detection unit 320, and transmits identification information of the control unit 310 itself and position information including the position of the worker PW to the production management device 100 via the communication unit 350.

[0046] The detection unit 320 is realized by various sensors such as a beacon sensor, an acceleration sensor, and an azimuth sensor, and detects the position and movement of the work assistance apparatus 300. The detection unit 320 supplies the detection data to the control unit 310.

[0047] As shown in FIG. 8, beacons BC1, BC2, and BC3 are arranged in accordance with locations in the production site PS where a worker PW can move. Beacons BC1, BC2, and BC3 are installed, for example, on the ceiling of a room where the production site PS is formed. Each beacon is assigned a unique ID and emits a beacon signal including the ID information. A beacon sensor functioning as the detection unit 320 of the work support device 300 carried by the worker PW receives the beacon signals emitted from each of the beacons BC1, BC2, and BC3. The number and locations of beacons arranged in the production site are arbitrary.

[0048] 7, the display unit 330 is realized by a display device such as an LCD (Liquid Crystal Display), a PDP (Plasma Display Panel), or an organic EL (Electro-Luminescence) display, and displays various information under the control of the control unit 310. The display unit 330 displays, for example, instructions indicated by the worker instruction information received from the production management device 100 on a display screen. The display screen of the display unit 330 may also serve as a touch panel and a keyboard as input devices.

[0049] The input / output unit 340 is realized by, for example, an interface for connecting to an input device such as a keyboard for inputting operation signals and an output device such as a speaker for outputting audio data, and inputs various data from the input device and outputs various data to the output device according to the control of the control unit 310.

[0050] The communication unit 350 is, for example, a communication interface for performing wireless communication. By The communication unit 350 transmits and receives various data to and from the production management device 100 via a wireless LAN under the control of the control unit 310. For example, the communication unit 350 transmits location information to the production management device 100. The communication unit 350 also receives work instruction information from the production management device 100.

[0051] Next, the production management processing executed by production management device 100 in the learning stage will be described with reference to the flowchart shown in Fig. 9. Control unit 110 of production management device 100 repeatedly executes the production management processing at a predetermined cycle, for example, in response to the launch of an application that executes the production management processing. The operation of the production management processing corresponds to the production management method of production management system 1 according to this embodiment.

[0052] First, the control unit 110 acquires operation information of the production facility 200 (step S101). The operation information acquisition unit 111 of the control unit 110 acquires the operation information by, for example, transmitting a transmission request to the production facility 200 via the communication unit 150 to instruct the production facility 200 to transmit the operation information, and receiving the operation information transmitted from the production facility 200 in response to the transmission request.

[0053] Next, the control unit 110 acquires the position information of the worker PW (step S102). The position information acquisition unit 112 of the control unit 110 acquires the position information of the worker PW, for example, by transmitting a transmission request to the work support device 300 via the communication unit 150 to instruct the work support device 300 to transmit the position information, and receiving the position information transmitted from the work support device 300 in response to the transmission request.

[0054] Next, the control unit 110 identifies the work status of the worker PW and the production facility 200 based on the location information of the worker PW and the operation information of the production facility 200 (step S103). The work status identification unit 113 of the control unit 110 refers to the production facility work status identification table shown in Fig. 4 and the worker work status identification table shown in Fig. 5, and identifies the work status of the production facility 200 and the worker PW as one of "solo work," "team work," or "non-operation" based on the location information of the worker PW and the operation information of the production facility 200.

[0055] Next, the control unit 110 determines the content of instructions to be given to the worker PW and the production facility 200 based on predetermined conditions (step S104). For example, when the work status of the worker PW identified by the work status identification unit 113 is non-operational, the instruction content determination unit 114 of the control unit 110 determines the work to be performed by this worker PW. For example, the instruction content determination unit 114 determines to instruct the worker PW to perform individual work such as inspection and testing of the production facility 200 or measurement of a machined workpiece, or to perform cooperative work such as removing a machined workpiece from the production facility 200 after various types of processing have been completed and installing a workpiece to be machined.

[0056] In addition, for example, when the work status identification unit 113 identifies that the work status of both the worker PW and the production equipment 200 is non-operating, the instruction content determination unit 114 decides to instruct the non-operating production equipment 200 to switch its operating mode to an energy-saving mode.

[0057] Next, the control unit 110 notifies the production equipment 200 and the worker PW of the instruction content (step S105). The production equipment instruction information notifying unit 115 of the control unit 110 generates production equipment instruction information instructing a switch to the energy saving mode determined by the instruction content determining unit 114, and transmits the information to the corresponding production equipment 200 via the communication unit 150. The production equipment 200 that has received the production equipment instruction information instructing a switch to the energy saving mode switches its operation mode from the normal mode to the energy saving mode.

[0058] Furthermore, the worker instruction information notification unit 116 of the control unit 110 generates worker instruction information indicating the instruction content determined by the instruction content determination unit 114, and transmits the information to the corresponding work support device 300 via the communication unit 150. The worker PW performs work in accordance with the instruction content displayed on the display screen of the work support device 300.

[0059] After executing the process of step S105, the control unit 110 ends the production management process.

[0060] As described above, in the production management system 1 according to this embodiment, the production management device 100 acquires operation information indicating the operation status of the production equipment 200 and location information indicating the location of the worker PW, identifies the work status of the production equipment and the worker PW based on this information, determines instructions for the production equipment 200 and the worker PW to improve production efficiency and reduce energy consumption, and notifies the production equipment 200 and the worker PW of the instructions. This makes it possible to improve production efficiency and reduce energy consumption in a production format in which production equipment and workers work together to carry out production work.

[0061] The present disclosure is not limited to the above-described embodiments, and various modifications and applications are possible without departing from the gist of the present disclosure.

[0062] In the above embodiment, when the condition that the work status of both the worker PW and the production equipment 200 identified by the work status identification unit 113 are non-operating is satisfied, the instruction content determination unit 114 determines to instruct the non-operating production equipment 200 to switch the operation mode to the energy saving mode. However, the instruction content determination unit 114 may add another condition to the conditions for determining the instruction to switch the operation mode to the energy saving mode, such as that the worker PW is not present near the production equipment 200 whose work status has been identified as non-operating.

[0063] Furthermore, when these conditions are met, the production management device 100 may switch the production equipment 200 to an energy-saving mode, and may also switch air conditioners, ventilation fans, hot and cold water supply devices, etc. installed around the production equipment 200 to an energy-saving mode as well.

[0064] In the above embodiment, the work status identification unit 113 identifies the work status based on the operation information of the production equipment 200 and the location information of the worker PW. However, in addition to the location information of the worker PW, the work status identification unit 113 may also incorporate, for example, information on the movement path ML of the worker PW at the production site PS, as shown in FIG. 10, as an element for identifying the work status. FIG. 10 shows the movement path ML of the worker PW moving from the guardhouse ST toward the production equipment 200e, traveling back and forth between the production equipment 200e and the production equipment 200a multiple times, and then returning to the guardhouse ST. This indicates that the worker PW did not enter the vicinity of the production equipment 200b, 200c, 200d, or 200f. By considering the movement path of the worker PW at the production site PS in this way, the production equipment 200 can more accurately identify the work status of the production equipment 200 and the worker PW and easily identify the production equipment 200 that is a target for energy consumption reduction.

[0065] In the above embodiment, the work status identification unit 113 identifies the work status as one of "solo work," "team work," or "non-operation" based on the operation information of the production equipment 200 and the location information of the worker PW. However, the work status identification unit 113 may further subdivide and identify the work status of the production equipment 200 and the worker PW.

[0066] Furthermore, the production management device 100 may manage a production plan indicating work content assigned in advance to a worker PW. Then, the control unit 310 of the work support device 300 receives input of identification information of the worker PW via the input / output unit 340, and inquires of the production management device 100 about the work content to be handled by this worker PW. The work content assigned in advance to the worker PW, indicated by the response to this inquiry, may be displayed on the display unit 330, and the worker PW may proceed with the work according to the work content displayed on the display screen.

[0067] In the above embodiment, the mobile object that performs production activities in cooperation with the production facility 200 has been described using the worker PW and the work support device 300 carried by the worker PW as an example. However, as described above, the production management system 1 may include other mobile objects, such as an automatic conveying device, instead of or in addition to the worker PW and the work support device 300. In this case, the mobile object, such as the automatic conveying device, is assumed to have at least the same functions as the worker PW and the work support device 300. More specifically, the mobile object is a robotic device that performs cooperative operations with the production facility 200, and is appropriately equipped with, for example, a control means, such as a computer, that controls the overall functions of the robotic device; a communication means that communicates data with the production management device 100 to exchange position information of the robotic device itself and mobile object instruction information from the production management device 100; a transport / movement means that transports workpieces from a material storage location to the production facility 200 and transports machined workpieces from the production facility 200 to a product storage location; and an arm means that attaches and detaches machined workpieces to and from the production facility 200.

[0068] Furthermore, the production management system 1 may use machine learning to determine the content of instructions to the production equipment 200 and the worker PW. In this case, the production management device 100 may input, for example, operation information of the production equipment 200, location information of the worker PW, etc., and generate a learning model that outputs the work status of the production equipment 200 and the worker PW, and content of instructions to the production equipment 200 and the worker PW for reducing energy consumption while improving production efficiency.

[0069] In the above embodiment, for example, the control program executed by the processor 101 that realizes the control unit 110 of the production management device 100 is stored in advance mainly in the storage 103. However, the present disclosure is not limited to this, and the control program for executing the various processes described above may be implemented in an existing general-purpose computer, framework, workstation, or the like, to function as a device equivalent to the production management device 100 according to the above embodiment. The same applies to the control programs executed by the processor that realizes the control unit 210 of the production facility 200 and the processor that realizes the control unit 310 of the work support device 300.

[0070] Such programs may be provided in any manner, for example, by storing them on a computer-readable recording medium (such as a flexible disk, a CD (Compact Disc)-ROM, or a DVD (Digital Versatile Disc)-ROM) and distributing them, or by storing the programs in storage on a network such as the Internet and providing them by downloading them.

[0071] Furthermore, when the above processing is performed by sharing the work between an OS (Operating System) and an application program, or by cooperation between the OS and the application program, only the application program may be stored on a recording medium, storage, etc. Alternatively, the program may be superimposed on a carrier wave and distributed over a network. For example, the program may be posted on a bulletin board system (BBS) on a network and distributed over the network. The program may then be launched and run under the control of the OS in the same way as other application programs, thereby designing the above processing to be performed.

[0072] The present disclosure allows various embodiments and modifications without departing from the broad spirit and scope of the present disclosure. Furthermore, the above-described embodiments are intended to explain the present disclosure and do not limit the scope of the present disclosure. In other words, the scope of the present disclosure is defined by the claims, not the embodiments. Various modifications made within the scope of the claims and the meaning of equivalent disclosures are considered to be within the scope of the present disclosure.
