  Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the invention according to the claims. In addition, not all the combinations of features described in the embodiments are essential for the solving means of the invention.

  FIG. 1 schematically shows an example of a communication environment of the work management apparatus 100. The work management apparatus 100 according to the present embodiment manages work performed by the worker 30 who performs work on the work target device 400. The work target device 400 may be any device, for example, a communication device that configures a wireless network such as a mobile phone network. The work may be any work, for example, a communication device setting work and a repair work.

  The work management apparatus 100 includes a procedure storage unit 102 that stores work procedure data indicating a work procedure for the work target device 400. The work management apparatus 100 transmits the work procedure data stored in the procedure storage unit 102 to, for example, the information terminal 300 used by the worker 30. The worker 30 may proceed with the work while browsing the work procedure indicated by the work procedure data displayed by the information terminal 300. The information terminal 300 is, for example, a PC (Personal Computer), a tablet terminal, a mobile phone such as a smartphone, and a wearable terminal.

  The work management apparatus 100 and the information terminal 300 may communicate via the network 10. The network 10 may include at least one of a dedicated network such as an in-house LAN, the Internet, and a telephone network. The work target device 400 may also be connected to the network 10 by communication. The work target device 400 may not be connected to the network 10 by communication.

  FIG. 2 schematically shows an example of work procedure data 200. In the work procedure data 200, process names, work contents, set work times, restoration process contents, and restoration process times of a plurality of work processes may be registered. FIG. 2 exemplifies a case where the data format of the work procedure data 200 is a table format. The work procedure data 200 includes a process name column 202, a work content column 204, a set work time column 206, and a recovery process content column 208. And a recovery processing time column 210. Note that the data format of the work procedure data 200 may be another data format.

  The process name is a name for identifying a work process. The work content may be a text indicating the work content of the work process.

  The set work time may be an average time required to carry out the work in the work process. The set work time is set by, for example, a creator who generates work procedure data. For example, the creator determines the set work time by experimentally performing the work process. Further, the generator may determine the set work time based on statistical data of the time required when the work process is performed at the actual work site.

  The content of the recovery process may be text indicating the content of the recovery process for returning the work target device 400 to the state before the start of the work step after the work process is performed on the work target device 400. The recovery processing time may be an average time required for the recovery processing. The recovery processing time is registered by, for example, a creator who generates work procedure data. The creator determines the restoration processing time by, for example, performing the restoration process experimentally. Further, the generator may determine the recovery processing time based on statistical data of the time required when the recovery processing is performed at the actual work site.

  A completion deadline may be set for the work on the work target device 400. For example, when the work target device 400 is a communication device configuring a wireless network, the start time is set at midnight when the usage amount of the wireless network is reduced in order to reduce the influence on the wireless network user, and the usage amount increases. The completion deadline is set early in the morning.

  Here, when the work is not completed by the completion deadline because each work process takes more time than expected or a failure occurs in the middle of the work process, the work target device 400 before the work is started by the completion deadline. It may be desirable to return to the state. For example, when adding a new function by stopping the operation of the wireless network, even if the new function is not added than when the operation of the wireless network cannot be resumed even after the completion deadline, It may be desirable to be able to resume operation of the wireless network before the completion deadline.

  Conventionally, whether the work is continued in the middle of the work on the work target device 400 or the work for returning the work target device 400 to a state before the work is started (sometimes referred to as a switch-back work) is started. Judgment was often made based on the experience, but it was difficult to judge accurately. Therefore, the work management apparatus 100 according to the present embodiment calculates the switch-back time required for returning the work target device 400 to the state before the work starts based on the work progress information and work procedure data for the work target device 400. Derived and provided to the worker 30. Thereby, accurate determination by the worker 30 can be supported.

  For example, the work management apparatus 100 may derive the switchback time by summing up the recovery processing times registered for the work processes that have been completed among the plurality of work processes. The case where the work indicated by the work procedure data 200 in FIG. 2 is performed will be described as an example. For example, when the process up to step c is completed, the work management apparatus 100 sets the return time as 10 minutes or 30 minutes. And 60 minutes obtained by adding 20 minutes. Then, the work management apparatus 100 provides the worker 30 with the derived switch-back time of 60 minutes. Thereby, accurate determination by the worker 30 can be supported.

  FIG. 3 schematically shows an example of the functional configuration of the work management apparatus 100. The work management apparatus 100 includes a procedure storage unit 102, a procedure transmission unit 104, a procedure acquisition unit 106, a progress acquisition unit 110, a history storage unit 120, a return time derivation unit 130, a return time output unit 132, a warning unit 134, and a distribution. An acquisition unit 140, a distribution output unit 142, a return procedure generation unit 150, and a return procedure output unit 152 are provided. In addition, it is not essential that the work management apparatus 100 includes all of these configurations.

  The procedure storage unit 102 stores a plurality of work procedure data. The procedure transmission unit 104 transmits work procedure data stored in the procedure storage unit 102. For example, the procedure transmission unit 104 transmits the work procedure data selected by the worker 30 among the plurality of work procedure data stored in the procedure storage unit 102 to the information terminal 300.

  Selection by the worker 30 may be performed via the information terminal 300. For example, the work management apparatus 100 displays a list of a plurality of work procedure data stored in the procedure storage unit 102 on the information terminal 300, and the procedure transmission unit 104 receives the work procedure data selected by the worker 30 from the list. Transmits to the information terminal 300.

  The procedure acquisition unit 106 acquires work procedure data from the procedure storage unit 102. The procedure acquisition unit 106 may acquire the same work procedure data as the work procedure data transmitted to the information terminal 300 by the procedure transmission unit 104.

  The progress acquisition unit 110 acquires work progress information on the work target device 400 by the worker 30. The progress acquisition unit 110 acquires the start time for each of a plurality of work processes included in the work procedure data acquired by the procedure acquisition unit 106, for example. Further, the progress acquisition unit 110 acquires an end time for each of a plurality of work processes included in the work procedure data acquired by the procedure acquisition unit 106, for example.

  The progress acquisition unit 110 may receive at least one of a start time of each of the plurality of work processes and an end time of each of the plurality of work processes from the information terminal 300. For example, the information terminal 300 transmits at least one of a start time and an end time in accordance with an instruction from the worker 30. For example, when starting each of a plurality of work processes, the worker 30 may input to the information terminal 300 that the work process is started. In addition, for example, the worker 30 may input information indicating that the work process has been completed to the information terminal 300 when each of the plurality of work processes is completed.

  The progress acquisition unit 110 may acquire progress information including information indicating a completed work process among a plurality of work processes included in the work procedure data acquired by the procedure acquisition unit 106. Further, the progress acquisition unit 110 may acquire progress information including the elapsed time from the start of the work indicated by the work procedure data. In addition, the progress acquisition unit 110 may acquire progress information including an elapsed time from the start of the currently implemented work process.

  The history storage unit 120 stores a work history. The history storage unit 120 may store a process work time indicating a time from the work start to the work end for each of a plurality of work processes indicated by the work procedure data acquired by the procedure acquisition unit 106. The process work time may be the time from the start time of one work process to the start time of the next work process. The process work time may be a time from the end time of the work process immediately before one work process to the end time of the one work process.

  The area specifying unit 120 may store work success / failure information indicating whether the work has succeeded or failed for each of the plurality of work processes. Further, the history storage unit 120 may store text indicating the content of work actually performed by the worker 30 for each of the plurality of work processes. Text indicating the content of work actually performed by the worker 30 is input by the worker 30 via the information terminal 300, for example.

  Further, the history storage unit 120 stores the timing at which the switchback operation is started and the time required to complete the switchback operation in association with each other when the switchover operation is performed by the operator 30. It's okay. In addition, the history storage unit 120 may store text indicating the contents of the recovery processing of each of the plurality of work processes. The text indicating the content of the recovery process is input by the operator 30 via the information terminal 300, for example.

  Based on the work procedure data acquired by the procedure acquisition unit 106 and the progress information acquired by the progress acquisition unit 110, the switchback time deriving unit 130 performs switchback required to return the work target device 400 to the state before the start of work. Deriving time. The switchback time deriving unit 130 may derive the switchback time according to the completed work process among the plurality of work processes. For example, the switchback time deriving unit 130 derives the switchback time by summing up the restoration processing times registered for the completed work processes. The switchback time deriving unit 130 may derive the switchback time by summing up the set work times registered for the completed work process.

  Further, the switchback time deriving unit 130 may derive the switchback time based on the work history stored in the history storage unit 120. For example, the return time deriving unit 130 derives the return time based on each process work time of the plurality of work processes. As a specific example, the setting work time corresponding to the process a is 20 minutes, the recovery processing time is 10 minutes, the process work time is 20 minutes, the setting work time corresponding to the process b is 40 minutes, and the recovery processing time is 30 minutes. The case where the process work time is 60 minutes will be described.

  The switchback time deriving unit 130 multiplies the recovery processing time of the process a by 1 which is the ratio of the process working time of the process a to the setting work time of the process a, By multiplying the ratio 3/2 by the recovery processing time of step b and adding it, 55 minutes may be derived as the switch-back time at the stage where the steps up to step b have been completed. As described above, the return time deriving unit 130 derives the time to be added as the return time by multiplying the restoration processing time by the coefficient corresponding to the ratio of the process work time corresponding to the set work time for each work process. You can do it. Here, the case where the ratio of the process work time corresponding to the set work time is directly adopted as a coefficient has been described as an example, but the present invention is not limited thereto. Other values may be used as long as the ratio of the process work time corresponding to the set work time is larger.

  Further, the return time deriving unit 130 is a ratio of the time obtained by adding the process work time of the process a and the process work time of the process b to the time obtained by adding the set work time of the process a and the set work time of the process b. Is multiplied by the time obtained by adding the restoration processing time of the process a and the restoration processing time of the process b, so that 53 minutes may be derived as the switch-back time at the stage where the process b is completed. As described above, the return time deriving unit 130 adds the recovery process time corresponding to the completed work process among the plurality of work processes, and the ratio of the total process work time to the total set work time. The switchback time may be derived by multiplying by a coefficient corresponding to. Here, the case where the ratio of the total process work time corresponding to the total set work time is directly adopted as a coefficient has been described as an example, but the present invention is not limited thereto. Other values may be used as long as the ratio of the total process work time corresponding to the total set work time is larger.

  The switchback time deriving unit 130 may derive a switchback time when a failure occurs during one of the plurality of work processes. The switchback time deriving unit 130 may derive the switchback time when a failure occurs by adding up the recovery process times associated with the completed work processes among the plurality of work processes.

  Further, the return time deriving unit 130 sums the recovery process time associated with the completed work process among the plurality of work processes and the recovery process time associated with the work process in progress. The switch back time may be derived. Further, the switchback time deriving unit 130 sums the elapsed time since the start of the work process in progress and the recovery process time associated with the completed work process among the plurality of work processes. The switch back time may be derived.

  Further, the switchback time deriving unit 130 associates the ratio of the elapsed time from the start of the work process with respect to the set work time associated with the work process being performed, with the work process being performed. The switchback time may be derived by summing the time multiplied by the recovery processing time and the recovery processing time associated with the completed work process among the plurality of work processes.

  The switchback time output unit 132 outputs the switchback time derived by the switchback time deriving unit 130. For example, the return time output unit 132 outputs the derived return time to the information terminal 300 and causes the information terminal 300 to display it.

  When the switchback time deriving unit 130 derives the switchback time at the stage where one of the plurality of work processes is completed, by causing the information terminal 300 to output the switchback time, At the stage where the one work process is completed, the time required to complete the switchback work can be grasped. As a result, it is possible to assist the operator 30 in determining whether to continue the work or shift to the switch-back work.

  Further, when the switchback time deriving unit 130 derives a switchback time when a failure occurs during the execution of one of the plurality of work processes, the switchback time is output to the information terminal 300. Thus, the operator 30 can be made aware of the switchback time when a failure occurs. Thereby, the operator 30 can be made aware of the expected time required to eliminate the failure.

  The warning unit 134 issues a warning based on the result of comparing the time when the switchback time derived by the switchback time deriving unit 130 is added to the current time and the switchback time limit. The switchback deadline is, for example, a work completion deadline. Further, the switch-back time limit may be a time limit different from the work completion time limit. For example, in a situation where the work must be completed by 5 o'clock but can be done by 6 o'clock if reverting, the deadline for reversion may be 6 o'clock.

  The warning unit 134 warns, for example, when the time obtained by adding the switchback time to the current time exceeds the time that goes back a predetermined time from the switchback time limit. Further, the warning unit 134 may warn when the time obtained by adding the switchback time to the current time exceeds the switchback deadline.

  The warning unit 134 may issue a warning by transmitting warning data to the information terminal 300. The information terminal 300 that has received the warning data transmitted by the warning unit 134 may output a warning to the worker 30. Thereby, it is possible to make the worker 30 know whether or not there is a margin for completing the switch back operation by the switch back deadline.

  The distribution acquisition unit 140 acquires distribution data of switchback time. The distribution data of the switchback time indicates a distribution of time required for the plurality of workers 30 to complete the switchback work when the switchback work is executed at the same timing in the same work procedure data. . The distribution acquisition unit 140 may acquire from the history storage unit 120 the time required for the plurality of workers 30 to complete the switchback operation.

  The distribution output unit 142 outputs the distribution data acquired by the distribution acquisition unit 140. The distribution output unit 142 may transmit the distribution data acquired by the distribution acquisition unit 140 to the information terminal 300. The information terminal 300 that has received the distribution data may display and output the received distribution data.

  Based on the work procedure data acquired by the procedure acquisition unit 106 and the progress information acquired by the progress acquisition unit 110, the switch-back procedure generation unit 150 generates switch-back procedure data indicating a procedure for switching back the work. The switchback procedure generation unit 150 may generate the switchback procedure data by combining the recovery process contents associated with the completed work process among the plurality of work processes indicated by the work procedure data. The failback procedure generation unit 150 combines only the restoration process contents associated with the work process in which work success / failure information indicating that the work is successful is registered among the plurality of work processes indicated by the work procedure data. Switchback procedure data may be generated.

  Further, the switchback procedure generation unit 150 may generate switchback procedure data based on the work history stored in the history storage unit 120. For example, the switch-back procedure generation unit 150 stores the text indicating the content of the work actually performed by the worker 30 stored in association with the completed work process among the plurality of work processes indicated by the work procedure data. By obtaining from the storage unit 120 and combining them, switch-back procedure data is generated.

  The switchback procedure output unit 152 outputs the switchback procedure data generated by the switchback procedure generation unit 150. The switchback procedure output unit 152 may transmit switchback procedure data to the information terminal 300. The information terminal 300 may display and output the received switch-back procedure data. As a result, the operator 30 can assist the switchback operation.

  FIG. 4 schematically shows a display example by the information terminal 300. FIG. 4 illustrates a display screen 220 displayed on the information terminal 300 according to control by the work management apparatus 100.

  The display screen 220 includes a progress display area 222, a switchback display area 232, and a distribution data display area 242. The progress display area 222 displays the progress status of a plurality of work processes indicated by the work procedure data.

  The progress display area 222 includes a process name column 224, a progress column 226, and a process work time column 228. The process name column 224 shows process names of a plurality of work processes. The progress column 226 indicates the progress status of each work process. Here, a case where “completed” is indicated in the work process in which the work is completed and “uncompleted” is indicated in the work process in which the work is not completed is illustrated. The process work time column 228 indicates the process work time of the work process.

  The switchback display area 232 includes a current time column 233, a completion deadline time column 234, a switchback completion expected time column 236, and a switchback time column 238. The current time column 233 indicates the current time. The completion deadline time column 234 indicates the completion deadline of the work registered in the work procedure data. The expected return completion time column 236 indicates the expected return completion time derived by the return time deriving unit 130. Here, an example of the expected completion time of switchback at the stage where the process a, the process b, and the process c are completed is illustrated. The switchback time column 238 shows the switchback time derived by the switchback time deriving unit 130.

  For example, the return time deriving unit 130 derives the return time using a history when the same work procedure data as the work procedure data being executed is executed. For example, the return time deriving unit 130 calculates the average time of the return times in the history in which the same work procedure data as the executed work procedure data is executed and the return operation is performed at the stage where the process c is completed. Derived as the current switchback time. When the same work procedure data as the work procedure data being executed is performed and there are 10 history records of the switch-back operation at the stage when step c is completed, the switch-back time deriving unit 130 determines whether the current switch-over time deriving unit 130 As the return time, the average of the 10 switchback times is derived.

  Further, the switchback time deriving unit 130 may derive the switchback time using a history when work procedure data different from the work procedure data being performed is performed. For example, the switchback time deriving unit 130 specifies work procedure data subsequent to the process a, the process b, and the process c, although the work procedure data is different from the work procedure data that is being implemented. Then, the switchback time deriving unit 130 derives the average switchback time in the history of the switchback operation performed at the stage where the specified work procedure data is performed and the process c is completed as the current switchback time. You can do it. In addition, the return time deriving unit 130 further uses the history data in which the same work procedure data as the work procedure data being executed is performed and the switch back operation is performed at the stage where the process c is completed. The return time may be derived.

  Moreover, although the case where the switchback time at the stage where the process c is completed is displayed is taken as an example here, the present invention is not limited to this. The return time deriving unit 130 may derive the return time at the stage where each process is completed for each of the process a, the process b, the process c, the process d, the process e, and the process f. The unit 132 may cause the information terminal 300 to display the switchback time at the stage where each process is completed. The switchback time output unit 132 displays the switchback time at the stage where each process is completed, for example, adjacent to the process work time column 228 in the progress display area 222.

  When the information terminal 300 displays the switchback display area 232 shown in FIG. 4, the worker 30 takes about 60 minutes when the switchback operation is started from now, and when the switchover operation takes 60 minutes. Thus, it can be easily grasped that the time at which the switch back operation is completed is 4:50.

  The distribution data display area 242 displays distribution data received from the distribution output unit 142. The distribution data display area 242 includes a distribution graph 244 and a warning line 246. The distribution graph 244 may indicate a distribution of time required for a plurality of workers 30 to complete the switch back work when the switch back work is executed at the same timing in the same work procedure data. The horizontal axis indicates the switchback time, and the vertical axis indicates the distribution of the switchback time indicating the number of people. In the example illustrated in FIG. 4, the work procedure data that is the same as the work procedure data that has been performed is performed, and 60 in the history in which the switch-back operation is performed at the timing when the process c is completed. It shows that the number of people required was 10.

  The warning line 246 indicates a threshold value for switching back when the predicted switching back completion time exceeds the completion deadline time. When the information terminal 300 displays the distribution data display area 242 shown in FIG. 4, the worker 30 switches back within the completion deadline when the worker who is relatively slow starts the switch back operation from now. There is a high possibility that the work cannot be completed, but if the work is not relatively slow, it is possible to grasp the situation that the switch-back work can be completed by the completion deadline time by starting the switch-back work from now .

  FIG. 5 schematically shows an example of the recovery process history data 250 stored in the history storage unit 120. In the recovery process history data 250, a process name, a recovery process history, a recovery process time, and an evaluation of each of a plurality of work processes may be registered.

  FIG. 5 illustrates a case where the data format of the recovery process history data 250 is a table format. The recovery process history data 250 includes a process name column 252, a recovery process history column 254, a recovery processing time column 256, and a recovery evaluation. It has a column 258. Note that the data format of the recovery processing history data 250 may be another data format.

  A process name is registered in the process name column 252. In the recovery process history column 254, text indicating the content of the recovery process is registered. In the recovery processing time column 256, the time required for the recovery processing is registered. In the restoration evaluation column 258, an evaluation for the contents of the restoration process is registered. The evaluation on the content of the restoration process may be input by the worker 30 and an evaluator who evaluates the work content of the worker 30.

  When a plurality of restoration processing histories corresponding to one work process are stored in the history storage unit 120, the restoration procedure generation unit 150 selects restoration processing with a higher evaluation and generates restoration procedure data. It's okay.

  FIG. 6 schematically shows an example of the flow of processing by the work management apparatus 100. The process illustrated in FIG. 2 is started when the work indicated by the work procedure data is started after the procedure acquisition unit 106 obtains the work procedure data. Each process illustrated in FIG. 6 is executed mainly by a control unit included in the work management apparatus 100.

  In step 602 (step may be abbreviated as S), the return time deriving unit 130 starts measuring the elapsed time. In step S604, it is determined whether one of the plurality of work processes indicated by the work procedure data has been completed. If it is determined that the process has not been completed, the process proceeds to S606. If it is determined that the process has been completed, the process proceeds to S612.

  In S606, it is determined whether a failure has occurred. The work management apparatus 100 may determine whether a failure has occurred in accordance with an input from the worker 30. The work management apparatus 100 may determine that a failure has occurred when data indicating that a failure has occurred is received from the work target device 400. If it is determined that a failure has occurred, the process proceeds to S608. If it is determined that a failure has not occurred, the process returns to S604.

  In S608, the return time deriving unit 130 derives the return time. The switchback time deriving unit 130 may derive the switchback time according to the completed work process among the plurality of work processes. Further, the switchback time deriving unit 130 may calculate the switchback time according to the completed work process among the plurality of work processes and the work process that was being performed when the failure occurred. In S610, the switchback time output unit 132 outputs the switchback time derived in S608 to the information terminal 300. Then, the process ends.

  In S612, the switchback time deriving unit 130 derives the switchback time. The switchback time deriving unit 130 may derive the switchback time according to the completed work process among the plurality of work processes. In S614, the switchback time output unit 132 outputs the switchback time derived in S612 to the information terminal 300.

  In S616, the warning unit 134 determines whether a warning is necessary. If it is determined in S616 that a warning is required, the process proceeds to S618, and if it is determined that a warning is not required, the process proceeds to S620. In S618, the warning unit 134 issues a warning.

  In S620, the distribution acquisition unit 140 acquires distribution data. In S622, the distribution data acquired in S620 is output to the information terminal 300.

  In S624, it is determined whether the work is completed. The work management apparatus 100 may determine that the work has been completed when all of the plurality of work processes indicated by the work procedure data have been completed. If it is determined in S624 that the work has not been completed, the process returns to S604, and it is determined in S604 whether or not the next work process is completed. If it is determined in S624 that the work has been completed, the process ends.

  In addition, although the case where the switch-back time is derived and output every time the process is finished is described as an example here, the present invention is not limited thereto. The work management apparatus 100 may periodically derive and output the switchback time. When the switchback time deriving unit 130 derives the switchback time before the work process is completed, the switchback time deriving unit 130 derives the switchback time according to the completed work process among the plurality of work processes and the work process being performed. You can do it.

  In the above description, each unit of the work management apparatus 100 may be realized by hardware or may be realized by software. Further, it may be realized by a combination of hardware and software. Further, the computer may function as the work management apparatus 100 by executing the program. The program may be installed in a computer constituting at least a part of the work management apparatus 100 from a computer-readable medium or a storage device connected to a network.

  A program that is installed in a computer and causes the computer to function as the work management apparatus 100 according to the present embodiment works on a CPU or the like to cause the computer to function as each unit of the work management apparatus 100. Information processing described in these programs functions as a specific means in which software and hardware resources of the work management apparatus 100 cooperate with each other by being read by a computer.

  As mentioned above, although this invention was demonstrated using embodiment, the technical scope of this invention is not limited to the range as described in the said embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be added to the above-described embodiment. It is apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention.

  The order of execution of each process such as operations, procedures, steps, and stages in the apparatus, system, program, and method shown in the claims, the description, and the drawings is particularly “before” or “prior to”. It should be noted that it can be realized in any order unless the output of the previous process is used in the subsequent process. Regarding the operation flow in the claims, the description, and the drawings, even if it is described using “first,” “next,” etc. for convenience, it means that it is essential to carry out in this order. It is not a thing.
