[0010] Hereinafter, embodiments of a work plan creation device according to the present invention will be described with reference to the drawings. Note that the following embodiments are examples for explaining the present invention and are not intended to limit the present invention. For example, the shapes, structures, materials, components, relative positional relationships, connection states, numerical values, mathematical formulas, contents of each step in the method, the order of each step, etc. shown in the following embodiments are examples, and may include contents not described below. In addition, geometric expressions such as parallel and orthogonal may be used, but these expressions do not indicate mathematical strictness and include substantially allowable errors, deviations, etc. Also, expressions such as simultaneous and identical include a substantially allowable range.

[0011] Further, the drawings are schematic diagrams that are appropriately emphasized, omitted, or adjusted in ratio for explaining the present invention, and are different from the actual shapes, positional relationships, and ratios. Also, the X-axis, Y-axis, and Z-axis shown in the figures represent orthogonal coordinates arbitrarily set for the explanation of the figures. That is, the Z-axis does not necessarily follow the vertical direction, and the X-axis and Y-axis do not necessarily exist in the horizontal plane.

[0012] In addition, in the following, there may be cases where a plurality of inventions are comprehensively described as one embodiment. Also, a part of the content described below is explained as an arbitrary component related to the present invention.

[0013] FIG. 1 is a diagram showing the device configuration of the work plan creation system 100. FIG. 2 is a diagram showing the functional configuration of the work plan creation system 100. The work plan creation system 100 is a system that creates a work plan for causing each of a plurality of work entities to perform a plurality of work processes, and re-creates a work plan that starts at an arbitrary time based on the progress of the work process. In the case of this embodiment, the work plan creation system 100 includes a work plan creation device 210, a server 220, and a terminal device 230. Note that the work plan creation system 100 may be realized by any combination or all of the functions of the work plan creation device 210, the server 220, and the terminal device 230 by one processor, or may be realized by separate processors.

[0014] A work entity is a subject that performs a work process, such as work equipment like a processing machine or an inspection machine, or a person who executes work. Note that a single work entity may perform a plurality of work processes, or a plurality of work entities may perform a single work process.

[0015] The type of the network 240 to which the work plan creation device 210, the server 220, and the terminal device 230 are connected is not particularly limited, and for example, a LAN (Local Area Network, in-house information communication network) that communicates based on a private IP address (local IP address) can be exemplified. Specifically, the network 240 is a network compliant with IEEE (The Institute of Electrical and Electronics Engineers) 802.3.

[0016] In addition, at least one of the work plan creation device 210, the server 220, and the terminal device 230 may be connected to a WAN (Wide Area Network), a so-called Internet, provided by a telecommunications carrier that can communicate based on a global IP address.

[0017] The server 220 includes a first processor 229 and is a device capable of transmitting and receiving information to and from the work plan creation device 210 and the terminal device 230 via the network 240. The specific server 220 is not particularly limited, but in the case of this embodiment, the server 220 is exemplified as a NAS (Network Attached Storage). Note that the server 220 may be, for example, a desktop computer, a laptop computer, or the like.

[0018] The server 220 stores data called a master for creating a work plan in the storage device 222. The server 220 realizes the communication unit 221 by causing the first processor 229 to execute a communication program. The communication unit 221 can transmit at least part of the information of the master to the work plan creation device 210.

[0019] The storage device 222 is a device capable of storing information long-term and outputting the stored data, and examples thereof include an HDD (Hard Disk Drive) and an SSD (Solid State Drive).

[0020] The master has at least parameter information. The parameter information is data used for creating a production plan. The parameter information is, for example, information that can identify a plurality of work processes at the work site, information indicating the capabilities of the work entity, etc. Specifically, when the work entity is a device, examples include what the device can process, the number of products produced per unit time or the number of processes processed per unit time by the device, the interval of regular maintenance, the time required for maintenance, etc. Also, when the work entity is a person, examples include the person's affiliation, work experience value (proficiency), the person's capabilities, etc. Further, the parameter information may include the relationship between work entities, for example, the proficiency of a person (operator) with respect to a device, the compatibility between people, etc. Also, the parameter information may include information associating the work entity and the work process, information fixing the period for implementing the work process, etc. Also, the parameter information may include information indicating the execution order of the work processes, etc.

[0021] The terminal device 230 is a device that outputs progress information indicating the progress of a work process executed according to a work plan, and is a computer equipped with a third processor 239 and a second display device 231. The terminal device 230 may be incorporated into the work equipment when the work entity is the work equipment. Also, the terminal device 230 may be a portable terminal device that a person can carry when the work entity is a person. The terminal device 230 communicates with at least one of the server 220 and the work plan creation device 210 via the network 240 and transmits the progress information. The terminal device 230 includes a browsing unit 170 and a collection unit 171 as a processing unit realized by causing the third processor 239 to execute a program.

[0022] Progress information is information indicating the progress of a work process. For example, as progress information, it is possible to exemplify how many parts have been manufactured and how many have been inspected at a predetermined time (for example, the first time). Further, the progress information may be information indicating what percentage of the work has progressed with respect to the number of parts to be processed in the work process included in the production plan. Further, the progress information may include state information indicating the state of the work subject. The state information can be exemplified by information indicating the state (situation) of the operator, such as when the device is stopped, during the recovery work of the device, or during an emergency meeting of the operator.

[0023] The collection unit 171 is a processing unit that acquires the progress information of the work process. Note that the method by which the collection unit 171 collects the progress information is not limited. For example, when the work subject is a device, the collection unit 171 may directly acquire the progress information from the device. Further, the collection unit 171 may acquire the progress information from the operator who uses the work subject. Further, when the work subject is a person, the collection unit 171 may acquire the progress information via the user interface.

[0024] The browsing unit 170 causes the second display device 231 to display the work plan acquired from the work plan creation device 210. Further, the browsing unit 170 may cause the second display device 231 to display the information necessary for inputting the progress information. Thereby, the work subject who is a person or the operator of the work subject who is a device such as work equipment can confirm the work plan.

[0025] The operation plan creation device 210 creates an operation plan for causing each of a plurality of operation entities to perform a plurality of operation steps based on parameter information provided in the master. The operation plan creation device 210 is a computer including a second processor 219 and a first display device 211. The operation plan creation device 210 can communicate with the server 220 via the network 240 and retrieve parameter information from the storage device 222 managed by the server 220. The specific operation plan creation device 210 is not particularly limited, and examples thereof include a desktop computer and a laptop computer. The operation plan creation device 210 includes a parameter acquisition unit 111, an operation plan creation unit 112, a progress acquisition unit 113, a completion acquisition unit 114, and an output unit 115 as a processing unit realized by causing the second processor 219 to execute an operation plan creation program.

[0026] The parameter acquisition unit 111 is a processing unit that acquires parameter information. The acquisition source of the information of the parameter acquisition unit 111 is not limited. In the case of the present embodiment, the parameter acquisition unit 111 acquires parameter information from the storage device 222 of the server 220. Note that the parameter acquisition unit 111 may acquire at least a part of the parameter information from a storage device (not shown) included in the operation plan creation device 210.

[0027] The operation plan creation unit 112 is a processing unit that creates an operation plan based on the acquired parameter information. FIG. 3 is a diagram showing an operation plan created by the operation plan creation device 210 based on parameter information. In the case of the present embodiment, the operation plan creation unit 112 creates a first operation plan based on first parameter information by the day before the day on which the operation plan is to be executed.

[0028] The operation plan creation unit 112 automatically assigns a plurality of operation steps to a plurality of operation entities respectively based on parameter information and the like. The assignment method of the operation plan creation unit 112 is not limited. For example, the operation plan creation unit 112 may automatically assign operation steps to operation entities by using a mathematical optimization method. Examples of the goals of mathematical optimization include maximizing production efficiency and completing all operation steps as early as possible.

[0029] In addition, the operation plan created by the operation plan creation unit 112 may be displayed on the first display device 211. Also, the operation plan may be displayed on the second display device 231 of the terminal device 230 via the network 240, the server 220, and the like.

[0030] In addition, the operation plan creation unit 112 creates a second operation plan based on the progress of the actual operation based on the first operation plan. The functions of such an operation plan creation unit 112 will be described later.

[0031] The progress acquisition unit 113 acquires progress information indicating the progress of the operation steps implemented by each operation entity at the first time based on the first operation plan created by the operation plan creation unit 112. The source from which the progress acquisition unit 113 acquires the progress information is not limited. In the case of this embodiment, the progress information is acquired from the terminal device 230.

[0032] FIG. 4 is a comparison diagram showing the relationship of the progress information with respect to the first operation plan. The comparison diagram shown in FIG. 4 may not be created. In addition, the progress acquisition unit 113 may create it based on the latest progress information and the like acquired from a plurality of terminal devices 230 (operation entities) when the first time (current time) is 9:20. In the case of this embodiment, the progress acquisition unit 113 acquires progress information from a plurality of operation entities at predetermined time intervals (not necessarily equal intervals).

[0033] Note that the progress acquisition unit 113 may create a comparison chart that represents the first work plan and the progress information in a comparable state for each of a plurality of work entities. Each time the progress acquisition unit 113 creates a comparison chart, it may display a new comparison chart on at least the first display device 211 of the work plan creation device 210 via the output unit 115. Thereby, the person in charge of creating the work plan who views the comparison chart on the first display device 211 or the like can grasp the progress of each work entity and each work process, and can easily determine whether to recreate the work plan according to the current situation.

[0034] The completion acquisition unit 114 acquires the expected completion time of the work processes in the in-progress state at the first time (in the case of this embodiment, the current time (9:20)). The work processes in the in-progress state refer to the work processes that are in the middle of the work and have not been completed yet. The method for acquiring the completion time is not limited. For example, the completion acquisition unit 114 derives the progress speed of the work based on the progress information acquired by the progress acquisition unit 113. Further, the completion acquisition unit 114 may derive and acquire the completion time by calculation, or may acquire the input completion time. Specifically, the completion acquisition unit 114 may acquire all the work in the work processes in the in-progress state from the first work plan, and acquire the completion time by deriving the completion time based on the derived progress speed and the acquired all work. Also, the person in charge of creating the work plan may acquire the completion time verbally or the like from the worker who is performing the recovery work on the work entity 4, and acquire the completion time based on the completion time input by the person in charge of creating the work plan into the work plan creation device 210. Further, the completion acquisition unit 114 may acquire the completion time expected by the work entity. Also, information indicating the work time corresponding to the recovery work recorded in the master or the like may be acquired to derive the completion time.

[0035] The completion acquisition unit 114 outputs, via the output unit 115, at least one of the progress information acquired by the progress acquisition unit 113 and the correspondence information in which the completion time is associated with the first work plan to the first display device 211. FIG. 5 is a diagram showing the progress information, the correspondence information in which the completion time and the first work plan are associated. As shown in FIG. 5, the end of the hatched band shown in the prediction column indicates the completion time. Also, the numbers described inside the hatched band indicate the progress information.

[0036] The person in charge of creating the work plan who has seen the correspondence information can easily grasp that the progress of work process 1 and the progress of work process 2 are behind at the stage of the current time (9:20), and can easily grasp that the recovery work of the work entity 4 will be completed at 13:00.

[0037] Based on the input of the second time by the person in charge of creating the work plan, the work plan creation unit 112 creates a second work plan based on at least one of the progress information acquired by the progress acquisition unit 113 and the completion time acquired by the completion acquisition unit 114, the second parameter information acquired by the parameter acquisition unit 111, and the second time to be re-planned, and outputs the second work plan to the first display device 211, the second display device 231, etc. via the output unit 115.

[0038] In the case of this embodiment, the person in charge of creating the work plan inputs, via the user interface, into the work plan creation device 210 the second time for replanning, that is, the time to start work according to the newly created second work plan, based on the output corresponding information. The parameter acquisition unit 111 acquires second parameter information. The second parameter information acquired by the parameter acquisition unit 111 may be at least part of the first parameter information already acquired as the second parameter information. The work plan creation unit 112 temporarily arranges the work processes so that the work processes according to the first work plan are arranged after the work processes (in the case of this embodiment, work process 1, work process 4, work process 7, recovery work) corresponding to the plurality of completion times acquired by the completion acquisition unit 114 respectively (see Fig. 6). The work plan creation unit 112 maintains the state of the first work plan, that is, creates the second work plan as a fixed condition, for the in-progress work processes (work process 2, work process 5) at the second time (13:00 in the case of this embodiment).

[0039] The second work plan created by the work plan creation unit 112 is output, via the output unit 115, to the first display device 211, the second display device 231, etc. in a state where the progress information acquired by the progress acquisition unit 113 and the completion times acquired by the completion acquisition unit 114 are associated (see Fig. 7).

[0040] Note that the present invention is not limited to the above embodiment. For example, in the present specification, another embodiment realized by arbitrarily combining the described components and excluding some of the components may also be an embodiment of the present invention. Also, modification examples obtained by applying various modifications conceivable by those skilled in the art without departing from the gist of the present invention, that is, the meaning indicated by the language described in the claims, with respect to the above embodiment are also included in the present invention.

[0041] For example, in the above embodiment, the server 220, the terminal device 230, and the work plan creation device 210 are described as communicating with each other via the network 240, but the server 220, the terminal device 230, and the work plan creation device 210 may communicate directly with each other.

[0042] Also, although the first work plan, the second work plan, etc. have been described for display on display devices such as the first display device 211 and the second display device 231, it does not deny display on display devices other than the first work plan and the second work plan, and the first work plan, the second work plan, etc. may be displayed by printing on paper.
