As shown in FIG. 4, the control unit 314 includes a work instruction generation unit 3141, a work possible person determination unit 3142, and an information generation unit 3143.

When the work request generation unit 3141 receives the work request information J2 via the first communication unit 311, the work instruction generation unit 3141 generates the work attribute information J3 illustrated in FIG. 7. The work instruction generation unit 3141 refers to the work management information J1 stored in the storage unit 313 when generating the work attribute information J3. The work attribute information J3 is information indicating the attribute of the work requested to be carried out, which is the support work requested to be carried out in the work request information J2. As shown in FIG. 7, the work attribute information J3 is, for example, information in which the notification authority information J31, the line identification information J32, and the required work priority information J33 are associated with each other.

The notification authority information J31 is information indicating the upper limit of the authority level of the worker OP who should be notified of the work request information J2, which is set according to the severity level of the work requested to be performed. In the example shown in FIG. 7, “level 7” is registered as the notification authority information J31. To describe with reference to FIGS. 5 to 7, “W01” indicating the work required to be performed registered in the work type information J11 of the work request information J2 is indicated by the severity information J12 of the work management information J1. “Level 7” is associated as the severity level. Therefore, the work instruction generation unit 3141 sets “level 7” according to the severity level as the notification authority information J31 indicating the attribute of the work requested to be performed.

The line identification information J32 is information for identifying the mounting line on which the component mounter 2 that has transmitted the work request information J2 is arranged, out of the plurality of mounting lines L01, L02, L03, L04. In the example shown in FIG. 7, “L02” is registered as the line identification information J32. To describe with reference to FIGS. 6 and 7, “L02” indicating the mounting line L02 is registered in the mounting line ID information J21 of the work request information J2. Therefore, the work instruction generation unit 3141 sets the same “L02” as the mounting line ID information J21 as the line identification information J32 indicating the attribute of the work requested to be performed.

The required work priority information J33 is information indicating the priority level of the implementation of the required work. In the example shown in FIG. 7, “level 5” is registered as the required work priority information J33. Explaining with reference to FIGS. 5 to 7, “W01” indicating the work requested to be performed registered in the work type information J11 of the work request information J2 is indicated by the priority information J13 of the work management information J1. “Level 5” is associated as the priority level. Therefore, the work instruction generation unit 3141 sets “level 5” as the requested work priority information J33 indicating the attribute of the work requested to be performed.

The work instruction generating unit 3141 generates the work instruction information J4 illustrated in FIG. 8 by adding the work attribute information J3 generated as described above to the work request information J2. This work instruction information J4 is transmitted to all the mobile terminal devices 32 by the second communication unit 312.

When the second communication unit 312 receives the work availability information J6 (FIG. 12), which will be described later, transmitted from the mobile terminal device 32, the work possible person determination unit 3142 carries out the work required work based on the work availability information J6. It is determined whether or not there is a worker OP who can do the job. The information generation unit 3143 generates information according to the determination result of the workable person determination unit 3142. It is assumed that the determination result of the workable person determination unit 3142 indicates that there is a worker OP who can carry out the work requiring work. In this case, the information generation unit 3143 generates work enabler determination information J7 (FIG. 13), which will be described later, indicating that there is a worker OP who can perform the work requiring work. The work available person determination information J7 is transmitted to the specific mobile terminal device 32 by the second communication unit 312. Details of the workable person determination unit 3142 and the information generation unit 3143 will be described later.

In the following description, the worker attribute information J5A to J5E will be collectively referred to as "worker attribute information J5".

The input unit 324 is a unit to which various information is input by the input operation of the operator OP. The work availability information J6, which will be described later, is input to the input unit 324 (FIG. 12).

As shown in FIG. 9, the control unit 325 includes a notification determination unit 3251, a notification control unit 3252, and a position specifying unit 3253.

The position specifying unit 3253 specifies the position of the mobile terminal device 32, and adds the specified position to the worker attribute information J5 as worker position information J54 indicating the current position of the worker OP.

FIG. 11 is a diagram for explaining the work instruction process executed by the information management device 31 and the notification determination process executed by the mobile terminal device 32. As described above, when the work instruction information J4 is generated by the work instruction processing of the work instruction generation unit 3141 in the information management device 31, the work instruction information J4 is transmitted to all the mobile terminal devices 32. In the mobile terminal device 32, the notification determination unit 3251 executes a notification determination process of determining whether or not the notification unit 322 needs to notify the work request information J2 included in the work instruction information J4 received by the terminal communication unit 321. .. The notification determination unit 3251 compares the worker attribute information J5 stored in the storage unit 323 with the work attribute information J3 included in the work instruction information J4 to notify the work request information J2 of the notification unit 322. Determine the necessity. The notification control unit 3252 controls the notification operation of the notification unit 322 when the notification determination unit 3251 determines that the notification of the work request information J2 by the notification unit 322 is necessary.

In the work management system 3 according to the present embodiment, the work instruction information J4 in which the work attribute information J3 is added to the work request information J2 from the component mounter 2 is transmitted from the information management device 31 to each mobile terminal device 32. .. In each mobile terminal device 32 that has received the work instruction information J4, the notification determination unit 3251 reads the worker attribute information J5 from the storage unit 323, and the work attribute information J3 included in the worker attribute information J5 and the work instruction information J4. By comparing with, it is determined whether or not the notification of the work request information J2 by the notification unit 322 is necessary. Then, when it is determined that the notification by the notification unit 322 is necessary, the notification unit 322 notifies the work request information J2 by the control of the notification control unit 3252.

That is, in each mobile terminal device 32, the necessity of notification of the work request information J2 is determined in consideration of the attribute of the work requested to be performed in the work request information J2 and the attribute of the worker OP. To be done. Then, the information is notified only in the mobile terminal device 32 that needs to be notified of the work request information J2. Thereby, the worker OP carrying the portable terminal device 32 notified of the work request information J2 can recognize the component mounter 2 that needs to perform the support work based on the work request information J2. On the other hand, since the worker OP who does not need to be notified of the work request information J2 is not notified of the information, it is possible to avoid confusion caused by the notification of the information. As a result, as a whole of the plurality of mounting lines L01, L02, L03, L04, the efficiency of the support work by the worker OP can be improved.

Further, even if the worker OP is performing another work at a position away from the component mounter 2 that needs to perform the support work, the work request information J2 notified by the mobile terminal device 32 should be confirmed. This makes it possible to understand the necessity of carrying out support work. Further, as described above, the work request information J2 is individually considered in each mobile terminal device 32 in consideration of the attribute of the work requested to be performed in the work request information J2 and the attribute of the worker OP. It is determined whether or not to notify. As a result, it is not necessary for the information management device 31 to collectively manage the information necessary for the determination. Therefore, it is possible to determine whether or not the notification of the work request information J2 is necessary with high mobility in each mobile terminal device 32.

A more detailed determination operation of the notification determination unit 3251 will be described. The notification determination unit 3251 determines that the notification of the work request information J2 by the notification unit 322 is necessary when the authority level condition and the line condition are satisfied. The authority level condition is a condition indicating that the authority level indicated by the worker authority information J51 is equal to or lower than the upper limit of the authority level indicated by the notification authority information J31. The line condition is a condition indicating that the mounting line specified by the line specifying information J32 is included in the work charge line information J52. Explaining with reference to FIGS. 3, 8, 10, and 11, the authority level indicated by the operator authority information J51 is the upper limit of the authority level indicated by the notification authority information J31 for all of the operators OPA to OPE. "Level 7" or lower. Therefore, all the operators OPA to OPE satisfy the authority level condition. On the other hand, it is the workers OPB and OPE that the mounting line “L02” specified by the line specifying information J32 is included in the worker-in-charge line information J52. Therefore, the workers OPB, OPE satisfy the line condition, and the workers OPA, OPC, OPD do not satisfy the line condition. Therefore, in the mobile terminal device 32B carried by the worker OPB and the mobile terminal device 32E carried by the worker OPE, the notification determination unit 3251 determines that the work request information J2 needs to be notified. Then, the notification unit 322 notifies the work request information J2 under the control of the notification control unit 3252 of the mobile terminal devices 32B and 32E.

Further, it is assumed that the current position of the worker OP indicated by the worker position information J54 satisfies the worker position condition indicating that the current position of the worker OP is within a predetermined range AR from the component mounter 2 that has transmitted the work request information J2. (See FIG. 3). In this case, the notification determination unit 3251 determines that the notification of the work request information J2 by the notification unit 322 is necessary if the authority level condition is satisfied even if the line condition is not satisfied. In the example shown in FIGS. 3 and 11, the worker OPC does not satisfy the line condition, but satisfies the worker position condition. Therefore, in addition to the workers OPB and OPE, the notification determining unit 3251 also determines that the work request information J2 needs to be notified in the mobile terminal device 32C carried by the worker OPC. Then, the notification unit 322 notifies the work request information J2 under the control of the notification control unit 3252 of the mobile terminal device 32C. As a result, the worker OPC near the component mounter 2 that needs to perform the support work can be notified of the work request information J2.

Further, it is assumed that the priority level indicated by the performed work priority information J53 satisfies the priority level condition indicating that it is lower than the priority level indicated by the required work priority information J33. In this case, when the notification determination unit 3251 satisfies the authority level condition and the line condition, or satisfies the authority level condition and the worker position condition and satisfies the priority level condition, the work request information J2. The notification unit 322 determines that the notification is necessary. In the example shown in FIGS. 3 and 11, the workers OPB, OPC, and OPE correspond to those satisfying the above conditions. Therefore, in each of the mobile terminal devices 32B, 32C, 32E carried by the workers OPB, OPC, OPE, the notification determination unit 3251 determines that the notification of the work request information J2 is necessary. Then, the notification unit 322 notifies the work request information J2 under the control of the notification control unit 3252 of each mobile terminal device 32B, 32C, 32E. In this aspect, in each mobile terminal device 32, the notification determination unit 3251 can determine that the notification of the work request information J2 by the notification unit 322 is necessary when the priority level condition is satisfied. That is, when the priority level of the support work currently being carried out is lower than the priority level of the work requiring work, the work request information J2 is notified. On the other hand, when the priority level of the support work currently being carried out is equal to or higher than the priority level of the work requested to be carried out, the work request information J2 is not notified. As a result, the worker OP is prevented from being confused by the notification of the work request information J2 regarding the work requiring work having a low priority level, and can concentrate on the support work having a high priority level.

FIG. 12 is a diagram for explaining the work availability notification process executed by the mobile terminal device 32. In the specific mobile terminal device 32 (hereinafter, referred to as “attention terminal device”) for which the notification operation of the work request information J2 by the notification unit 322 is performed, the work permission/inhibition information J6 is input to the input unit 324 by the input operation of the worker OP. Is entered. The work permission/inhibition information J6 is information indicating whether or not the work required to be performed can be performed. In the example shown in FIG. 12, the mobile terminal devices 32B, 32C, 32E carried by the operators OPB, OPC, OPE are the target terminal devices, and the work permission/inhibition information J6 is input to the input unit 324 in these target terminal devices. To be done. When the work availability information J6 is input to the input unit 324, the terminal-side communication unit 321 executes work availability notification processing for transmitting the work availability information J6 to the information management device 31. By receiving the work permission/prohibition information J6, the information management device 31 can grasp the target terminal devices 32B, 32C, 32E from among the plurality of mobile terminal devices 32 to which the work request information J2 has been notified.

13 and 14 are diagrams for explaining the work possible person notification process executed by the information management device 31. When the second communication unit 312 receives the work availability information J6 from each of the target terminal devices 32B, 32C, 32E, the information management device 31 executes the work available person notification process. Specifically, in the information management device 31, the work possible worker determination unit 3142 determines whether or not there is a worker OP who can carry out the work to be performed based on each work availability information J6. Then, the information generation unit 3143 generates information according to the determination result of the workable person determination unit 3142. It is assumed that the determination result of the workable person determination unit 3142 indicates that there is a worker OP who can perform the work required to be performed. In this case, the information generation unit 3143 generates workable person determination information J7 indicating the determination result. Then, the second communication unit 312 transmits the generated work available person determination information J7 to each of the focused terminal devices 32B, 32C, 32E (FIG. 13).

In each of the attention terminal devices 32B, 32C, 32E that have received the workable person determination information J7 from the information management device 31, the notification control unit 3252 causes the notification unit 322 to notify the workable person determination information J7. Thereby, each worker OPB, OPC, OPE carrying the target terminal device 32B, 32C, 32E can confirm that there is a worker OP capable of performing the work requested to be performed. Therefore, it is possible to prevent a plurality of people from duplicating the required work.

On the other hand, it is assumed that the determination result of the work possible worker determination unit 3142 indicates that there is no worker OP who can perform the work requested to be performed. In this case, the work instruction generation unit 3141 generates new work instruction information J4A in which the upper limit of the authority level indicated by the notification authority information J31 is set high and the mounting line types indicated by the line identification information J32 are set large. .. Then, the second communication unit 312 transmits the generated new work instruction information J4A to all the mobile terminal devices 32 (FIG. 14). In the new work instruction information J4A, at least the upper limit of the authority level indicated by the notification authority information J31 is set to be high, and a large number of mounting line types indicated by the line identification information J32 are set. As a result, the target range of the mobile terminal device 32 that is determined to need to be notified of the work request information J2 can be widened. Therefore, it is possible to increase the possibility that there is a worker OP who can perform the work requested to be performed.

[Control operation related to management of support work in work management system]
Next, the control operation relating to the management of the support work in the work management system 3 will be described with reference to the flowcharts of FIGS. FIG. 15 is a flowchart of the work instruction process executed by the information management device 31. FIG. 16 is a flowchart of the notification determination process executed by the mobile terminal device 32. FIG. 17 is a flowchart of the work availability notification process executed by the mobile terminal device 32. FIG. 18 is a flowchart of the work possible person notification process executed by the information management device 31.

In the information management device 31, when the work request information J2 from the component mounter 2 is received via the first communication unit 311, the work instruction process is started (step a1). First, the work instruction generation unit 3141 generates work instruction information J4 by adding work attribute information J3 to the work request information J2 (step a2). Then, the second communication unit 312 transmits the generated work instruction information J4 to all mobile terminal devices 32 (step a3). When the transmission of the work instruction information J4 is completed, the work instruction processing by the information management device 31 ends.

When the mobile terminal device 32 receives the work instruction information J4 from the information management device 31 via the terminal side communication unit 321, the notification determination process is started (step b1). First, the notification determination unit 3251 compares the worker authority information J51 with the notification authority information J31 to determine whether the authority level condition is satisfied (step b2). The notification determination unit 3251 shifts the processing to step b3 when the authority level condition is satisfied. On the other hand, when the authority level condition is not satisfied, the notification determination unit 3251 determines that the notification of the work request information J2 is unnecessary (step b8).

In step b3, the notification determination unit 3251 determines whether or not the line condition is satisfied by comparing the work-in-charge line information J52 and the line identification information J32. The notification determination unit 3251 shifts the processing to step b4 when the line condition is satisfied. On the other hand, when the line condition is not satisfied, the notification determination unit 3251 shifts the processing to step b5.

In step b4, the notification determination unit 3251 determines whether or not the priority level condition is satisfied by comparing the performed work priority information J53 and the requested work priority information J33. The notification determination unit 3251 determines that the notification of the work request information J2 is necessary when the priority level condition is satisfied (step b6). On the other hand, when the priority level condition is not satisfied, the notification determination unit 3251 determines that the notification of the work request information J2 is unnecessary (step b8).

In step b5, the notification determination unit 3251 determines whether or not the worker position condition is satisfied based on the worker position information J54. If the operator position condition is satisfied, the notification determination unit 3251 shifts the processing to step b4 described above. On the other hand, when the worker position condition is not satisfied, the notification determination unit 3251 determines that the notification of the work request information J2 is unnecessary (step b8).

When the notification determination unit 3251 determines that the work request information J2 needs to be notified in step b6, the notification unit 322 notifies the work request information J2 under the control of the notification control unit 3252 (step b7). Thereby, the worker OP carrying the portable terminal device 32 notified of the work request information J2 can recognize the component mounter 2 that needs to perform the support work based on the work request information J2. On the other hand, since the worker OP who does not need to be notified of the work request information J2 is not notified of the information, it is possible to avoid confusion caused by the notification of the information.

In the target terminal devices 32B, 32C, 32E notified of the work request information J2, when the work availability information J6 is input to the input unit 324, the work availability notification process is started (step c1). First, the terminal-side communication unit 321 transmits the work availability information J6 to the information management device 31 (step c2). When the work possible person determination information J7 from the information management device 31 is received by the terminal side communication unit 321 after the work permission information J6 is transmitted (step c3), the notification unit 322 notifies the work possible person determination information J7. (Step c4). Thereby, each worker OPB, OPC, OPE carrying the target terminal device 32B, 32C, 32E can confirm that there is a worker OP capable of performing the work requested to be performed.

On the other hand, when new work instruction information J4A from the information management device 31 is received by the terminal-side communication unit 321 after the work permission/inhibition information J6 is transmitted (step c5), based on the new work instruction information J4A, it is determined that The notification determination process of steps b1 to b8 described above is newly executed.

When the information management device 31 receives the work availability information J6 from the terminal devices 32B, 32C, 32E of interest via the second communication unit 312, the work possible person notification process is started (step d1). First, the work possible person determination unit 3142 identifies the target terminal devices 32B, 32C, 32E from among the plurality of mobile terminal devices 32, which are the transmission sources of the work availability information J6 and have been notified of the work request information J2. (Step d2). Then, the work possible worker determination unit 3142 determines whether or not there is a worker OP who can perform the work requested to be performed, based on the work availability information J6 (step d3).

It is assumed that the determination result of the workable person determination unit 3142 indicates that there is a worker OP who can perform the work required to be performed. In this case, the information generation unit 3143 generates the workable person determination information J7 indicating the determination result (step d4). Then, the second communication unit 312 transmits the generated work enabler determination information J7 to each of the focused terminal devices 32B, 32C, 32E (step d5).

On the other hand, it is assumed that the determination result of the work possible worker determination unit 3142 indicates that there is no worker OP who can perform the work requested to be performed. In this case, the work instruction generating unit 3141 generates new work instruction information J4A (step d6). Then, the second communication unit 312 transmits the generated new work instruction information J4A to all the mobile terminal devices 32 (step d7).

Although the embodiment of the present invention has been described above, the present invention is not limited to this, and for example, the following modified embodiment can be adopted.

[Modified Embodiment of Work Management System]
In the above embodiment, when the work availability information J6 transmitted from the terminal devices 32B, 32C, 32E of interest is information indicating that there is no worker OP who can perform the work requested, a new work instruction is issued. Although the configuration in which the information J4A is generated has been described, the present invention is not limited to this configuration. In the work management system 3 according to the modified embodiment, the processing contents of the work availability notification processing of the mobile terminal device 32 and the work possible person notification processing of the information management device 31 are different from those of the above embodiment. Modifications of the work availability notification process and the work possible person notification process will be described with reference to FIGS. 19 to 21.

In the attention terminal devices 32B, 32C, and 32E that have notified the work request information J2, the work availability information J6 is input to the input unit 324 by the input operation of the worker OP. When the work availability information J6 is input to the input unit 324, the terminal-side communication unit 321 executes work availability notification processing for transmitting the work availability information J6 to the information management device 31. When the second communication unit 312 receives the work availability information J6 from each of the target terminal devices 32B, 32C, 32E, the information management device 31 executes the work available person notification process. Specifically, in the information management device 31, the work possible worker determination unit 3142 determines whether or not there is a worker OP who can carry out the work to be performed based on each work availability information J6. Then, the information generation unit 3143 generates information according to the determination result of the workable person determination unit 3142.

It is assumed that the determination result of the workable person determination unit 3142 indicates that there is a worker OP who can perform the work required to be performed. In this case, the information generation unit 3143 generates workable person determination information J7 indicating the determination result. Then, the second communication unit 312 transmits the generated work available person determination information J7 to each of the focused terminal devices 32B, 32C, 32E.

On the other hand, it is assumed that the determination result of the work possible worker determination unit 3142 indicates that there is no worker OP who can perform the work requested to be performed. In this case, the information generation unit 3143 generates the worker determination reminder information J8. The worker decision reminder information J8 is information for urging the worker OP having the highest authority level indicated by the notification authority information J31 to determine the operator who will carry out the required work. In the examples shown in FIGS. 19 to 21, the worker OPE carrying the mobile terminal device 32E corresponds to the worker with the highest authority level. Then, the second communication unit 312 transmits the generated worker determination reminder information J8 to the target terminal devices 32B, 32C, 32E (FIG. 19).

In the attention terminal devices 32B, 32C, 32E that have received the worker determination reminder information J8 from the information management device 31, the notification unit 322 notifies the worker determination reminder information J8 by the control of the notification control unit 3252 (FIG. 19). The worker OPE having the highest authority level can determine the worker OP who carries out the work requested work by checking the worker determination reminder information J8 notified by the mobile terminal device 32E of the worker. As a result, it is possible to reliably carry out the work requested to be carried out.

The worker OPE who has confirmed the worker determination reminder information J8 may input the worker designation information J9 to the input unit 324 of the mobile terminal device 32E of the worker. The worker designation information J9 is information for designating the worker OP who carries out the work requested to be carried out. The worker designation information J9 input to the input unit 324 is transmitted to the information management device 31 by the terminal side communication unit 321 (FIG. 20).

When the second communication unit 312 receives the operator designation information J9 from the mobile terminal device 32E, the information generation unit 3143 in the information management device 31 generates the determination notification information J10. The decision notification information J10 is information for notifying that the worker OP who carries out the work requested to carry out the work is determined by the designation of the worker OPE. Then, the second communication unit 312 transmits the generated determination notification information J10 to each of the target terminal devices 32B, 32C, 32E (FIG. 21).

In the attention terminal devices 32B, 32C, 32E that have received the decision notification information J10 from the information management device 31, the notification unit 322 notifies the decision notification information J10 by the control of the notification control unit 3252 (FIG. 21). Thereby, each worker OPB, OPC, OPE carrying the target terminal device 32B, 32C, 32E can confirm the worker OP who carries out the work requested to be carried out.

Next, in the work management system 3 according to the modified embodiment, the work availability notification process executed by the mobile terminal device 32 will be described with reference to the flowchart of FIG. 22, and the work possible person notification process executed by the information management device 31. This will be described with reference to the flowchart of FIG.

In the target terminal devices 32B, 32C, 32E notified of the work request information J2, when the work availability information J6 is input to the input unit 324, the work availability notification process is started (step e1). First, the terminal-side communication unit 321 transmits the work availability information J6 to the information management device 31 (step e2). When the worker-side reminder information J8 from the information management device 31 is received by the terminal-side communication unit 321 after the work permission/inhibition information J6 is transmitted, the notification unit 322 notifies the worker-determination reminder information J8 (step e3 ).

In the attention terminal devices 32B, 32C, 32E after the notification of the worker determination reminder information J8, the control unit 325 determines whether or not the authority level of the worker OP is the highest, based on the operator authority information J51. (Step e4). If it is determined that the authority level is the highest, the process proceeds to step e5, and if it is determined that the authority level is not the highest, the process proceeds to step e7. In the examples shown in FIGS. 19 to 21, it is determined that the worker OPE has the highest authority level in the mobile terminal device 32E, and the worker OPB, OPC has the highest authority level in the other mobile terminal devices 32B and 32C. It is determined that it is not a rank.

At step e5, in the portable terminal device 32E, the operator designation information J9 is input to the input unit 324 by the input operation of the worker OPE. When the worker designation information J9 is input to the input unit 324, the terminal-side communication unit 321 transmits the worker designation information J9 to the information management device 31 (step e6).

When the determination notification information J10 from the information management device 31 is received by the terminal-side communication unit 321 after the notification of the worker determination reminder information J8 (step e7), the notification unit 322 notifies the determination notification information J10 ( Step e8). Thereby, each worker OPB, OPC, OPE carrying the target terminal device 32B, 32C, 32E can confirm the worker OP who carries out the work requested to be carried out.

In the information management device 31, when the work permission/inhibition information J6 is received from the target terminal devices 32B, 32C, 32E via the second communication unit 312, the work possible person notification process is started (step f1). First, the work possible person determination unit 3142 identifies the target terminal devices 32B, 32C, 32E from among the plurality of mobile terminal devices 32, which are the transmission sources of the work availability information J6 and have been notified of the work request information J2. (Step f2). Then, the work possible worker determination unit 3142 determines whether or not there is a worker OP who can perform the work requested to be performed, based on the work availability information J6 (step f3).

It is assumed that the determination result of the workable person determination unit 3142 indicates that there is a worker OP who can perform the work required to be performed. In this case, the information generation unit 3143 generates the workable person determination information J7 indicating the determination result (step f4). Then, the second communication unit 312 transmits the generated work available person determination information J7 to each of the focused terminal devices 32B, 32C, 32E (step f5).

On the other hand, it is assumed that the determination result of the work possible worker determination unit 3142 indicates that there is no worker OP who can perform the work requested to be performed. In this case, the information generation unit 3143 generates the worker determination reminder information J8 (step f6). Then, the second communication unit 312 transmits the generated worker determination reminder information J8 to each of the focused terminal devices 32B, 32C, 32E (step f7).

When the worker designation information J9 from the portable terminal device 32E is received after the worker determination reminder information J8 is transmitted (step f8), the information generation unit 3143 generates the determination notification information J10. Then, the second communication unit 312 transmits the generated determination notification information J10 to each of the target terminal devices 32B, 32C, 32E (step f9). In the noted terminal devices 32B, 32C, 32E that have received this decision notification information J10, each worker OPB, OPC, OPE can confirm the worker OP who carries out the work requested to be performed.
