The process shown in Fig. 1 is an example of the fastening management method and fastening management program of the present disclosure, and the technology of the present disclosure is not limited to such a configuration.

[0026] 1, this fastening management process includes a process step (S101) of reading worker information for each plant facility 3, a process step (S102) of accessing the computer of each plant facility 3 at a set timing, a process step (S103) of reading plant information and work information for each plant facility 3, a process step (S104) of determining the placement status of workers 10, and a process step (S105) of adjusting the placement of workers 10 relative to the plant facility 3. This fastening management process is executed by a fastening management system 2 shown in FIG.

[0027] Process for reading worker information for each plant facility 3 (S101): The fastening management system 2 performs monitoring and adjustment processing of the placement and work status of the workers 10 in, for example, the assembly, maintenance, and inspection processing of a plurality of plant facilities 3A, 3B, ... 3X. These plant facilities 3A, 3B, ... 3X may be facilities that operate independently, facilities operated by the same organization, or facilities that operate cooperatively within the same site and may be facilities that are divided for the management of maintenance and inspection.

[0028] The fastening management system 2 is connected to a management server 4 that manages these plant facilities 3A, 3B, ..., 3X, and reads worker information including identification information and skill information of workers 10A-1, 10A-2, ..., 10X-N working in the plant. This identification information is an example of information for individually identifying workers 10A-1, 10A-2, ..., 10X-N and for authenticating those who have permission to enter and work in the plant.

[0029] Step (S102) of accessing the computer of each plant facility at a set timing: The plant facilities 3A, 3B, ... 3X are equipped with plant management servers 6A, 6B, ... 6X which manage the respective facilities and the workers 10. The management servers 6A, 6B, ... 6X monitor the entry and exit into the plant facility and allocate the workers 10 to their work locations, for example, using the identification information of the workers 10. The identification information of the workers 10 may be, for example, biometric information such as the face, retinal pattern, and fingerprints of the workers 10, as well as information registered on their ID cards, for example.

[0030] The plant management servers 6A, 6B, ...6X may collect identification information, for example, when a worker 10 arrives at work, when work begins at the plant, when a work process is completed, when an additional work process occurs, or when determining whether the worker 10 is appropriately positioned after being positioned or during work.

[0031] The management server 4 is connected to each plant management server 6A, 6B, .... 6X via wired or wireless communication, and is able to access the identification information and work process information of each worker 10 at preset times or when instructed by a supervisor with management authority.

[0085] The management server 4 then determines the distribution state of work capacity relative to the work load for each work location in the plant equipment 3A, 3B, ... 3X, and judges whether the allocation process of the workers 10 is appropriate. If there is a work location where the work capacity is insufficient, the management server 4 performs an adjustment process such as moving the workers 10 of the other plant equipment 3A, 3, ... 3X. In adjusting the workers 10, for example, if multiple workers 10 are nominated as candidates, a selection process may be performed based on conditions such as the acquisition results and number of training sessions in the practical training related to the plant equipment 3A, 3B, ... 3X, as well as the recent date of the most recent training.

[0086] <Advantages of the First Embodiment> According to this configuration, the following effects can be obtained.

[0087] (1) By comparing the workload and work capacity stored in the work management database 5, it becomes possible to determine whether the placement of the workers 10 in the plant equipment 3A, 3B, ... 3X is appropriate or not, and the work status can be visualized, thereby improving the reliability of management processing for the plant equipment 3A, 3B, ... 3X.

[0088] (2) By calculating the work capacity of each worker 10 using the skills, experience, and training certification information of each worker 10, it is possible to assign workers 10 with appropriate work skills to each work location of the plant equipment 3A, 3B, ... 3X, thereby reducing the workload of personnel assignment processing.

[0089] (3) Since the workers 10 having the necessary work skills can be assigned, the safety of assembly, maintenance and inspection work can be improved.

[0090] (4) By matching the skill information of the workers 10 with the skill information required for the work location, appropriate allocation of workers 10 can be performed regardless of the manager's experience level.

[0091] Second Embodiment Fig. 6 shows an example of a fastening management process according to the second embodiment. The process shown in Fig. 6 is an example, and the technology of the present disclosure is not limited to this process. In this fastening management process, S indicates some of the processes, and the numbers attached to S indicate an example of the order.

[0092] In this fastening management process, the positioning of the worker 10 is monitored and adjustment processing is performed, for example, at the start of fastening management such as maintenance or inspection, or between specific work processes, as a monitoring timing.

[0093] As shown in FIG. 6, the fastening management process includes a process of acquiring deployment information of workers 10 from each piece of plant equipment (S201), a process of comparing the skill condition information and workload of the plant equipment with the work capacity of the deployed workers 10 (S202), a process of determining the work capacity (S203), a process of monitoring the work status (S204), a process of checking for unassigned workers 10 in other plant equipment (S205), a process of judging the skill conditions (S206), a process of issuing deployment instructions to workers 10 (S207), and a process of issuing instructions to replace workers 10 (S208).

[0094] Step of acquiring location information of the worker 10 from each piece of plant equipment (S201): In the fastening management system 70, the management server 4 collects the location information of the worker 10 from each of the plant management servers 6A, 6B, 6C, and 6D.

[0095] Step of comparing the skill requirement information and workload of the plant equipment with the work capacity of the assigned worker 10 (S202): The management server 4 uses the collected deployment information, information on the work locations of each piece of plant equipment 3A, 3B, 3C, 3D, and workload information calculated from the work content to compare with the work capacity of the assigned worker 10.

[0096] In the comparison process, for example, as shown in FIG. 7, it is determined whether the work capacity information 74 of the worker 10 actually assigned matches or is insufficient against the required work capacity information 72 set for each piece of plant equipment 3A, 3B, 3C, and 3D.

[0097] This work capacity information 74 may be, for example, information on the number of people, or may be information stored in the work capacity section 66 of the work management database 5. Here, the required work capacity information 72 and the work capacity information 74 are represented by icons representing the workers 10, or the like, as a method for easily visualizing the comparison results.

[0098] Alternatively, the comparison between the required work capacity information 72 and the work capacity information 74 may be expressed, for example, as calculated numerical value information.

[0099] Work capacity determination process (S203): The management server 4 calculates the work load and work capacity for each of the plant equipment 3A, 3B, 3C, and 3D, and then compares these to generate a screen showing the results of the comparison between the required work capacity information 72 and the work capacity information 74.

[0100] In the comparison process, for example, as shown in FIG. 7, in "Plant A" and "Plant D", the work capacity information 74 is insufficient compared to the required work capacity information 72.

[0101] Furthermore, in the "B plant" and the "C plant", each has a work capacity greater than the required work capacity information 72, and excess work capacity information 76 is displayed.

[0102] When the work capacity is sufficient for the workload (YES in S203), the management server 4 determines that the allocation process of the workers 10 by the plant management servers 6A, 6B, 6C, and 6D is appropriate.

[0103] Work status monitoring step (S204): When the management server 4 determines that the worker 10 allocation process is appropriate, it continues to monitor the work status or monitors the work status until the next judgment of the work capacity.

[0104] Step of confirming unassigned workers 10 in other plant equipment (S205): If the work capacity is insufficient for the workload (NO in S203), the management server 4 determines that the allocation process of the workers 10 by the plant management servers 6A, 6B, 6C, 6D is inappropriate, and confirms unassigned workers 10 in other plant equipment 3A, 3B, 3C, 3D. These unassigned workers 10 are displayed as excess work capacity information 76, for example, as shown in FIG. 7.

[0105] Skill condition determination process (S206): When the management server 4 extracts an unassigned worker 10 from the worker database 14A, 14B, 14C, 14D, it determines whether the worker 10 satisfies the necessary skill conditions set for the work location of the missing plant equipment 3A, 3B, 3C, 3D.

[0106] Placement instruction process for worker 10 (S207): When, for example, an unassigned worker 10 has the necessary skill conditions (YES in S206), the management server 4 outputs placement instructions to the worker 10 via the plant management servers 6A, 6B, 6C, 6D in which the worker 10 is registered. As a result, in the fastening management system 70, as shown in Fig. 7, relocation information is displayed with an arrow or the like pointing an icon display of excess work capacity information 76 to required work capacity information 72 of the destination plant equipment 3A, 3B, 3C, 3D.

[0107] Worker 10 replacement instruction process (S208): Furthermore, the management server 4 performs a determination process for the unassigned worker 10 that has been read out to determine whether or not the worker 10 has the necessary skill conditions. If the worker 10 does not have the skill conditions required for this work location (NO in S206), the management server 4 extracts another unassigned worker 10 and outputs an instruction to replace the worker 10.

[0108] <Configuration of the fastening management system 70> Fig. 7 shows an example of the configuration of a fastening management system. In Fig. 7, the same components as those in Fig. 2 are given the same reference numerals.

[0109] In this fastening management system 70, for example, the management server 4 performs monitoring and judgment processing of the placement status and work status of the workers 10 for the four pieces of plant equipment 3A, 3B, 3C, and 3D, and adjustment processing of the workers 10.

[0110] In the fastening management system 70, required work capacity information 72, work capacity information 74, and excess work capacity information 76 for each work location are generated as information indicating the deployment status of workers 10 deployed by, for example, the plant management servers 6A, 6B, 6C, and 6D of each plant facility 3A, 3B, 3C, and 3D.

[0111] The required work capacity information 72, work capacity information 74, and excess work capacity information 76 may be displayed on the information presentation unit 106 provided in the plant management servers 6A, 6B, 6C, and 6D, for example.

[0112] The management server 4 then uses the required work capacity information 72, work capacity information 74, and excess work capacity information 76 generated by each plant management server 6A, 6B, 6C, and 6D to determine the placement status of the workers 10 and perform placement adjustment processing for the workers 10 among the other plant equipment 3A, 3B, 3C, and 3D.

[0113] In addition, the fastening management system 70 may have plant identification information 78 set therein using a two-dimensional code or the like, which can access, for example, identification information for the plant equipment 3A, 3B, 3B, and 3D, component part information such as the constituent equipment, piping, flange joints, bolts and nuts, gaskets, and other information.

[0114] <Placement process of worker 10> FIG. 8 shows the worker allocation process performed by each plant management server.

[0115] 8, the plant management server 6A reads out the qualification information of the worker 10, the skill experience information 80 acquired in the flange fastening skill training device, the skill authentication information 82, and the like stored in the worker database 14A. Furthermore, the worker database 14A stores information on entry and exit to the plant facility 3A, work permission, and an ID tag 84 including the authentication information of the worker 10.

[0116] This ID tag 84 is provided with code information 86, such as a QR code (registered trademark), and is linked to authentication information for the worker 10 and management authority information including access to the plant management server 6A, etc.

[0117] A facial image 90 captured by an authentication device (not shown) is sent to the plant management server 6A as identification information 88 of the worker 10, and the authentication result and authentication information based on an ID card 92 attached to the worker 10 are also notified to the plant management server 6A. The plant management server 6A assigns personnel to work locations in the plant based on the authentication information and skill information of the workers 10.

[0118] The other plant management servers 6B, 6C, and 6D may also have the same configuration as the plant management server 6A, and may perform processing to assign the respective workers 10 to the respective work locations.

[0119] <Hardware for Management Server 4 and each plant management server 6> FIG. 9 shows an example of the hardware configuration of the management server and the plant management server.

[0120] The control unit 94 is configured by a computer having a communication function, and includes, for example, a processor 96, a storage unit 98, a communication unit 100, and an input / output unit (I / O) 102.

[0121] The processor 96 executes the OS (Operating System) in the memory unit 98 and performs information processing to realize various programs such as a fastening management program including authentication processing of the worker 10, registration in the worker database 14, comparison processing between the skill information of the worker 10 and the skill condition information of the work area, and judgment processing of the work progress status.

[0122] The management server 4 then performs calculations such as determining whether the placement of the workers 10 placed by each plant management server 6 is appropriate, calculating the workload and work ability, and adjusting the placement of the workers 10.

[0123] The storage unit 98 is an example of a recording medium, and includes storage elements such as a ROM (Read-Only Memory) and a RAM (Random-Access Memory). When configuring each plant management server 6, for example, the storage unit 98 stores an OS as well as programs for executing the process of arranging the workers 10 and the generation of instruction information.

[0124] Furthermore, in the case where the storage unit 98 constitutes, for example, the management server 4, a calculation processing program for workload and work ability, a comparison processing program for determining the deployment states of the workers 10, a deployment adjustment program for the workers 10, etc. are stored in the storage unit 98. Furthermore, the storage unit 98 stores, for example, various programs, a worker database 14, a plant database 16, a work status database 18, and a process information database 104.

[0125] For example, in the case of the management server 4, the communication unit 100 is a functional unit that connects to each plant management server 6. In addition, in the case of configuring the plant management servers 6A, 6B, 6C, and 6D, the communication unit 100 is a functional unit for transmitting and receiving information to and from an external database and a terminal device 12 provided to a worker 10 via wireless communication.

[0126] Under the control of the processor 96, the I / O 102 is connected to an external database (DB) 105 and a terminal device 12, and also displays information such as the results of determining the placement status of the worker 10, placement instructions, or placement adjustment instructions on the information presentation unit 106, and also inputs information from the operation input unit 107.

[0127] The information presentation unit 106 is an example of a means for displaying the overall operating status of the fastening management system 70 and information on the work location to be notified to the worker 10, and is configured, for example, with an information presentation device such as an LCD (Liquid Crystal Display).

[0128] The operation input unit 107 is an example of a means for inputting setting conditions for the management server 4 and the plant management servers 6A, 6B, 6C, and 6D and authentication information such as the ID number of the worker 10, and is equipped with an operation means such as a keyboard or a touch panel.

[0129] <Advantages of the second embodiment> According to this configuration, one of the following effects can be obtained.

[0130] (1) The same effects as in the first embodiment can be obtained.

[0131] (2) By having each of the plant facilities 3A, 3B, 3C, and 3D complement each other's insufficient work capabilities, it is possible to prevent insufficient fastening processing capabilities and work delays in some of the plant facilities 3A, 3B, 3C, and 3D.

[0132] (3) By visualizing the work capacity, the required work capacity, and the excess work capacity, the reliability of the fastening process of the plant equipment 3A, 3B, 3C, and 3D is improved and the management process is simplified.

[0133] Third embodiment Fig. 10 shows an example of a fastening management process according to the third embodiment. The process shown in Fig. 10 is an example, and the technology of the present disclosure is not limited to this process. In this fastening management process, S indicates some of the processes, and the numbers attached to S indicate an example of the order.

[0134] In the fastening management process, for example, it is monitored whether the fastening process is being performed in accordance with the process information, and if a delay in the process occurs, it is assumed that the lack of work capacity is due to an inappropriate allocation of workers 10, and adjustment processing for the workers 10 is performed.

[0135] As shown in FIG. 10, the fastening management process includes a step (S301) of acquiring positioning information of workers 10 from each piece of plant equipment, a step (S302) of reading process information of each piece of plant equipment from a process information database (DB) 104, a step (S303) of acquiring work reports from each piece of plant equipment, a step (S304) of determining the timing of determining the work status, a step (S305) of determining whether the work status matches the process information, a step (S306) of determining the priority of the process, a step (S307) of adjusting the workers 10, and a step (S308) of notifying the workers 10 of instruction information.

[0136] Step of acquiring location information of worker 10 from each piece of plant equipment (S301): In the fastening management system 70, the management server 4 collects location information of worker 10 from each of the plant management servers 6A, 6B, 6C, and 6D.

[0137] Step (S302) of reading process information for each piece of plant equipment from the process information database (DB) 104: The management server 4 accesses the process information database 104 and reads the process information for the fastening work set for each work location of the plant equipment 3A, 3B, 3C, and 3D.

[0138] Step of acquiring work reports from each plant equipment (S303): In the contract management process, the management server 4 acquires and reads work reports including the positioning information of the workers 10 of each plant equipment 3A, 3B, 3C, 3D and their work status from the plant management servers 6A, 6B, 6C, 6D.

[0139] Determining the timing for judging the work status (S304): The management server 4 uses, for example, a timer (not shown) to determine whether it is the timing for judging the work status by the fastening management process based on time information such as time information and the elapsed time since the previous monitoring process. The management server 4 may set the worker information and plant equipment information read from each of the plant management servers 6A, 6B, 6C, and 6D in the process information database 104.

[0140] Process for determining whether work status and process information match (S305): The management server 4 compares the process information stored in the process information database 104 with the work reports read from each plant management server 6 to determine the progress of the current fastening work at each work location or plant equipment 3A, 3B, 3C, 3D.

[0141] The management server 4 performs the determination process using, for example, the work time and work status information contained in the process information database 104. If the work status matches the process information or is within a predetermined range such as a predetermined error (YES in S305), the management server 4 returns to S303 and continues the monitoring process such as obtaining a work report.

[0142] Furthermore, if the work situation does not match the process information (NO in S305), the management server 4 determines that the allocation of the worker 10 is inappropriate, and proceeds to a reallocation process for the worker 10.

[0143] Process priority determination process (S306): The management server 4 recognizes the location where the delay or interruption of the work process is occurring as a location where the work capacity is insufficient as an adjustment process for the worker 10. Then, the management server 4 reads, for example, the process information database 104 and extracts the priority of the location where the worker 10 is inappropriately placed.

[0144] This priority is an example of information that is set based on, for example, the importance of the functional configuration of the plant equipment 3A, 3B, 3C, and 3D, the sequence of work processes in fastening work, etc. In other words, the priority is set to a high value for work or work locations that need to be assembled, maintained, or inspected first, so that they are processed preferentially. Conversely, the priority is set to a low value for the latter steps of the fastening management process, for example.

[0145] Then, the management server 4 compares the priority of a work location where a delay is occurring in the work process with the priority of a work location where a worker 10 having the skill information required for this work location is assigned.

[0146] Step of adjusting the workers 10 (S307): In this fastening management process, for example, for a work location where the work process is delayed, a worker 10 with the necessary skill information is moved from the other plant equipment 3A, 3B, 3C, 3D with a lower priority to adjust the work capacity. At this time, for example, the fastening management process may be interrupted in the work location of the other plant equipment 3A, 3B, 3C, 3D with a lower priority, or the work capacity may decrease due to a shortage of workers 10.

[0147] Step of notifying instruction information to worker 10 (S308): The management server 4 notifies the terminal device 12 of the worker 10 of instruction information including movement, work content, and setting information for fastening tools to the selected worker 10 based on the skill information and priority information of the work location, either directly or via the plant management server 6A, 6B, 6C, 6D to which the worker 10 belongs or is registered.

[0148] <Configuration of the fastening management system 70> Fig. 11 shows an example of the configuration of a fastening management system. In Fig. 11, the same components as those in Fig. 2 and Fig. 7 are given the same reference numerals.

[0149] This fastening management system 70 illustrates a case in which process information set in the fastening management process is taken into account in, for example, the arrangement status of the worker 10, the monitoring process of the work status, the judgment process, and the adjustment process of the worker 10.

[0150] The management server 4 stores, for example, a process information database 104. In determining the allocation status of the workers 10 allocated to each of the plant management servers 6A, 6B, 6C, and 6D, the management server 4 determines whether or not to allocate the workers 10 preferentially based on whether or not a delay has occurred in the work process. Then, based on the result of this determination, the management server 4 performs an adjustment process for the allocation of the workers 10 among the other plant facilities 3A, 3B, 3C, and 3D.

[0151] As a result, in the fastening management process, for example, if the fastening process of some of the plant equipment 3A, 3B, 3C, and 3D is extremely delayed, not only will unassigned workers 10 belonging to other plant equipment 3A, 3B, 3C, and 3D be assigned, but workers 10 who are in the middle of work will be moved and adjusted based on the priority set for the fastening management process steps.

[0152] <About the Process Information Database (DB) 104> Fig. 12 shows an example of the configuration of the process information database. The configuration shown in Fig. 12 is just an example.

[0153] This process information database 104 is an example of management data that includes, for example, work processes and work status of the assembly, maintenance, and management of plant equipment 3A, 3B, 3C, and 3D, and is an information source used for comparing work load and work capacity and for determining work capacity.

[0154] The process information database 104 includes, for example, a plant information section 110, a flange fastening section 112, a worker section 114, a work time section 116, a work content section 118, a set time section 120, a work status section 122, and an importance section 124, as shown in FIG.

[0155] The plant information section 110 stores information that identifies the plant equipment to which the worker 10 belongs or is assigned.

[0156] The flange fastening unit 112 stores information on the position of the flange to be fastened, as well as information on the work target such as the flange, gasket, bolts, and nuts.

[0157] The worker section 114 stores identification information of the worker 10 who is positioned at a work location such as a flange fastening section.

[0158] The work time section 116 stores time information on flange fastening, maintenance, and inspection work. This work time section 116 includes, for example, a start time section 1161 and an elapsed time section 1162. For example, when determining the progress of work, the management server 4 uses the information stored in the work time section 116 to compare a preset work set time with the elapsed time.

[0159] The work content section 118 stores information on the work content performed by the worker 10 at a work location such as a flange fastening section. This work content section 118 may store, for example, information similar to that stored in the workload section 64 of the work management database 5, or may link to data in the workload section 64.

[0160] Scheduled work time information for each work location is stored in the set time section 120. This scheduled work time information is an example of comparison information for determining the progress of the fastening management process, and may be set based on time information required for past assembly, maintenance, and inspection, for example.

[0161] The work status section 122 stores progress information included in the work reports notified to the management server 4 from the plant management servers 6A, 6B, 6C, and 6D, and the results of judgments made based on the work reports.

[0162] The importance section 124 stores priority information set for each work location of the plant equipment 3A, 3B, 3C, and 3D, and based on at least the work procedure of the fastening management process.

[0163] <About the work area of ​​the plant> FIG. 13 shows an example of work locations set in a plant.

[0164] This plant facility 130 is composed of a plurality of pipes and equipment, for example, as shown in Fig. 13. The fastening management process of the present disclosure includes the allocation process of workers 10 with specialized skills and knowledge to flange fastening parts that connect these pipes together, and to work sites such as the assembly, maintenance, and inspection of equipment.

[0165] In the plant facility 130, work locations are divided, for example, by flange fastening parts or equipment located within one or a certain distance range, and each work location is assigned work location identification information 132A, 132B, ... 132G, etc.

[0166] The work location includes, for example, information on flange fastening section 134, which is formed by connecting pipes having flange joints at their ends in opposing positions and fastening the flange joints with bolts and nuts, as work location identification information 132C. Furthermore, flange fastening section 134 has tag 136 attached, for example, to a part of the pipes or the surface of the flange joint. Access information, such as a two-dimensional code that can be read by terminal device 12 of worker 10, is printed on tag 136.

[0167] The worker 10 can obtain information such as the work location identification information 132C, the model number of the flange joint, the number of bolts and nuts to be fastened, and the diameter of the pipes, for example, by reading the access information of the tag 136 with the terminal device 12.

[0168] <About fastening work> FIG. 14 shows an example of the configuration of a terminal device that inputs instruction information for fastening work and generates a work report.

[0169] A worker 10 placed at a work site receives instruction information sent from the plant management servers 6A, 6B, 6C, 6D to which the worker belongs at a terminal device 12, as shown in FIG. 14, and inputs the instruction information to a controller 140 that controls the fastening process.

[0170] The terminal device 12 and the controller 140 are connected, for example, wirelessly or via a wire.

[0171] In addition, for example, the operator 10 may manually input instruction information to the controller 140. The instruction information to be set includes, for example, setting information such as the axial force and the tightening torque value T required for fastening the bolt and the nut, as well as the work location.

[0172] The controller 140 is a device for controlling a fastening tool 142 used in the fastening work, and inputs control instructions such as a tightening torque value T to the fastening tool 142 via a cable 144. The controller 140 includes a display screen 146 for displaying, for example, setting information, operation contents, and the state of the fastening tool 142, and an operation input unit 148 for inputting setting operations, numerical information, and the like.

[0173] The fastening tool 142 performs a fastening process for the flange fastening portion 134 based on setting information input through the controller 140. The fastening tool 142 includes tools such as a torque wrench and a nut runner into which various types of work data can be input and set.

[0174] In the flange fastening portion 134, for example, a gasket 152 is sandwiched between flanges 150A and 150B which are connecting means, and bolts 154 and nuts 156 are arranged at a plurality of fastening points set on the periphery.

[0175] For example, eight fastening points are set on the periphery of flanges 150A, 150B. That is, flanges 150A, 150B are fastened by eight bolts 154A, 154B, 154C, etc. and nuts 156A, 156B, 156C, etc., spaced at equal intervals of angle θ=45°. Gasket 152 is in contact with the opposing surfaces of flanges 150A, 150B and is arranged so as not to overlap with flow paths formed by piping or the like.

[0176] In the fastening management process, when the controller 140 performs fastening work using the fastening tool 142, it generates work report information one by one or for each specified number of man-hours, and notifies the plant management server 6A, 6B, 6C, 6D, or the management server 4 of the work report information via the terminal device 12.

[0177] <Third embodiment> According to this configuration, the following effects can be obtained.

[0178] (1) The same effects as those of the first and second embodiments can be obtained.

[0179] (2) By obtaining work reports from the work locations of each plant facility 3A, 3B, 3C, and 3D and comparing them with pre-set process information to understand the work status, the safety of the fastening management process can be improved.

[0180] (3) By utilizing the priority of the fastening processing work set in the process information, the relocation process of the worker 10 for the plant equipment 3A, 3B, 3C, and 3D can be set, thereby preventing delays in work time and processing stalls in only some of the plant equipment 3A, 3B, 3C, and 3D.

[0181] [Modifications] Modifications of the embodiment described above are listed below.

[0182] In the above embodiment, the selection of the worker 10 to be allocated among the plant facilities is performed by determining whether the skill information and work capacity, including the working power, of the worker 10 satisfy the workload conditions of the work location.
