The step of comparing the skill condition information and work load of the factory equipment with the work ability of the configured workers 10 ( S202 ): the management server 4 uses the collected configuration information to compare the factory equipment 3A, 3B, 3C, The 3D work site information or the work load information calculated from the work content is compared with the work capability of the assigned operator 10 .

For example, as shown in FIG. 7 , in the comparison process, it is determined that the workability information 74 created by the workers 10 that are actually arranged is relative to the necessary workability information set in each of the plant equipments 3A, 3B, 3C, and 3D. 72 is consistent or insufficient.

This workability information 74 may be, for example, the number of people information, or may be information stored in the workability section 66 of the work management database 5 . Here, as a means of easily visualizing the comparison result, the required work ability information 72 and the work ability information 74 are represented by icons or the like representing the worker 10 .

The comparison between the other necessary workability information 72 and the workability information 74 can also be represented by, for example, calculated numerical information or the like.

Workability determination step (S203): After the management server 4 calculates the work load and workability for each plant equipment 3A, 3B, 3C, and 3D, it compares these and generates information 72 showing the necessary workability and A screen and the like of the comparison result of the work ability information 74 .

For example, as shown in FIG. 7 , in the comparison processing, the workability information 74 is insufficient with respect to the required workability information 72 in the “A factory” and the “D factory”.

Moreover, "B factory" and "C factory" each have more work capacity than necessary work capacity information 72, and excess work capacity information 76 is displayed.

As the determination of the workability, the management server 4 determines that the workmanship is performed by the factory management servers 6A, 6B, 6C, and 6D when the workability is sufficient for the work load (“Yes” in S203 ). A configuration process of 10 is suitable.

Work state monitoring step ( S204 ): When the management server 4 has determined that the operator 10 placement process is appropriate, the management server 4 continues to monitor the work state or until the next work capability determination.

The step of confirming the unallocated workers 10 of other factory equipment (S205): When the management server 4 is not sufficient in the work capacity relative to the work load (“No” in S203), the management server 4 determines that the factory management server 6A is used. , 6B, 6C, and 6D are not suitable for the placement process of the workers 10, and it is confirmed that the workers 10 that are not placed in the other plant equipment 3A, 3B, 3C, and 3D are not configured. For example, as shown in FIG. 7 , the unassigned workers 10 are displayed as excess work capacity information 76 .

Skill condition determination step (S206): The management server 4 determines whether the unassigned workers 10 are extracted from the worker databases 14A, 14B, 14C, and 14D, and whether they meet the requirements set in the insufficient factory equipment 3A, 3B, The necessary skills for 3C and 3D work.

Step of instructing the arrangement of the worker 10 ( S207 ): For example, when the unallocated worker 10 has the necessary skills (“Yes” in S206 ), the management server 4 transmits the information through the factory where the worker 10 is registered. The management servers 6A, 6B, 6C, and 6D output configuration instructions to the operator 10 . As a result, as shown in FIG. 7 , in the tightening management system 70, the icon of the excess workability information 76 displays the necessary workability information 72 of the plant equipment 3A, 3B, 3C, and 3D of the moving destination by an arrow or the like. and display transfer information.

The step of instructing the replacement of the operator 10 (S208): In addition, when the management server 4 performs the judgment process of whether the operator 10 that has been read out and not allocated has the necessary skill conditions, if the operator 10 does not have the skills required by the work place. ("No" in S206), other unallocated workers 10 are extracted and a replacement instruction is output.

[third embodiment] FIG. 10 shows an example of the tightening management processing procedure in the third embodiment. The step shown in FIG. 10 is just an example, and the technology of the present disclosure is not limited to the technology of this step. In this tightening management process step, S is a part of the steps, and the number attached to S is an example of the sequence.

In the tightening management process, for example, whether or not the tightening process is performed according to the step information is monitored, and if there is a delay in the step, etc., it is presumed that the lack of work ability is caused by the improper arrangement of the workers 10, and The adjustment process of the operator 10 is performed.

For example, as shown in FIG. 10 , the tightening management process includes the following steps: a step of acquiring the arrangement information of the worker 10 from each factory equipment ( S301 ); The step of step information (S302); the step of obtaining the operation report from each plant equipment (S303); the step of judging the time point of judging the operation status (S304); the step of judging the agreement between the operation status and the step information (S305); The step of priority ( S306 ); the step of adjustment processing by the operator 10 ( S307 ); the step of notifying the operator 10 of instruction information ( S308 ).

The step of obtaining the configuration information of the operator 10 from each factory equipment ( S301 ): The tightening management system 70 instructs the management server 4 to collect the configuration information of the operator 10 from the factory management servers 6A, 6B, 6C, and 6D.

The step of reading the step information of each factory equipment from the step information database (DB) 104 (S302): the management server 4 accesses the step information database 104, and reads the information about the factory equipment 3A, 3B, 3C, Step information of the tightening operation set for each operation in 3D.

The step of acquiring the work report from each factory equipment ( S303 ): the management server 4 acquires and reads the information including each factory equipment 3A, 3B, The configuration information of the 3C, 3D operator 10 or the operation report of the operation status.

The step of determining the time point for determining the operation status ( S304 ): The management server 4 uses, for example, a timer (not shown) and determines whether it is based on time information or time information such as the elapsed time since the previous monitoring process Judgment time point of the work status by the tightening management process. The management server 4 may also set the operator information or factory equipment information read from each of the factory management servers 6A, 6B, 6C, and 6D in the step information database 104 .

The step of determining the consistency between the operation status and the step information ( S305 ): The management server 4 compares the step information stored in the step information database 104 with the operation report read from each factory management server 6 to determine The current progress status of each work site or the fastening work of the plant facilities 3A, 3B, 3C, and 3D.

The management server 4 uses, for example, the operation time or operation status information contained in the step information database 104 to perform the determination process. The management server 4 returns to S303 and continues monitoring processing such as job acquisition when the operation status matches the step information or is within a predetermined range such as a predetermined error (Yes in S305).

In addition, when the operation status does not match the step information (NO in S305 ), the management server 4 judges that the arrangement of the operator 10 is not appropriate, and transfers to the relocation process of the operator 10 .

The step of judging the priority of the steps ( S306 ): The management server 4 performs adjustment processing by the operator 10 , and recognizes the occurrence of delays or interruptions of the operation steps as the insufficiency of the operation ability. Furthermore, the management server 4 reads the step information database 104, for example, and extracts the priority of the inappropriate arrangement of the operator 10.

This priority is an example of information set in accordance with, for example, the importance of the functional configuration of the factory equipment 3A, 3B, 3C, and 3D, the order of work steps of the tightening operation, and the like. That is, the priority is, for example, a configuration in which a higher value is set for an operation or an operation that must be assembled, maintained, and inspected first, and the processing is performed with priority. Conversely, the priority may be set to a lower value for the program in the latter half of the tightening management process, for example.

Then, the management server 4 compares the priority of the work place where a delay occurs in the work step with the priority of the work place where the operator 10 having the necessary skill information for the work place is arranged.

Step of the adjustment processing by the operator 10 ( S307 ): In this tightening management processing, for example, it is necessary to move from the other factory equipment 3A, 3B, 3C, 3D of lower priority to the work place where the work steps have been delayed The operator 10 of the skill information can adjust the work ability. At this time, in the work of other plant equipments 3A, 3B, 3C, and 3D with low priority, for example, the tightening management process may be interrupted, or the workability may be reduced due to the shortage of the workers 10 .

The step of notifying the operator 10 of the instruction information ( S308 ): the management server 4 will directly, or via the factory management server 6A to which the operator 10 belongs or has logged in, according to the skill information and the priority information of the workplace. The operator 10 selected in , 6B, 6C, and 6D notifies the terminal device 12 of the operator 10 of instruction information including movement or work content and setting information for the fastening tool.
