Description

The present invention relates to a working time calculation system and a working time calculation method.

In recent years, with the declining working-age population due to the declining birthrate and aging population, there is an urgent need to improve productivity in various work environments. In order to improve productivity, it is necessary to visualize the current state of worker productivity and identify factors that reduce productivity.

For example, even in the field of information system operation, the behavior of workers responsible for operation (hereinafter referred to as operators) can be monitored using sensors (e.g., acceleration sensors and biological information sensors) and incident management systems (e.g., Redmine, ServiceNow, etc.). By collecting and visualizing the data, it is possible to calculate the time required for the worker's work.

In Patent Document 1, the work device arrival time and the work device departure time of workers working in an office are measured, and by taking the difference between them, the time required for work excluding the leaving time is calculated, and the worker's productivity is calculated. A technique for visualizing sexuality is disclosed.

Patent Literature 2 discloses a method for measuring the position of a worker's hand using an ultrasonic sensor bracelet worn by a worker in a warehouse and an ultrasonic sensor provided on a product shelf. By using the method disclosed in Patent Literature 2, it is possible to collect the time and details of work (such as picking up a product from a shelf) without inputting work information by the worker himself/herself.

Patent Literature 3 introduces a case where a worker carries a sensor and collects and visualizes work details input by the worker in order to formulate measures to improve productivity.

However, in the method disclosed in Patent Document 1, although the operator's absence time is calculated, if the operator transitions between a plurality of work locations and the transition is related to work (for example, from the terminal that received the customer's inquiry, , move to another terminal to actually perform work, and then move to another terminal to communicate the work results to the customer after completing the work), it is determined that the time away from work is not related to the main work Therefore, there is a possibility that there will be a discrepancy between the work time of the operator, excluding the time spent away from work, and the time required for the actual work of the operator. Furthermore, in an environment where a worker can perform multiple tasks at the same time, interrupting work (the act of interrupting the work the worker was engaged in and starting another task) occurs. In Patent Document 1, the time required for work is calculated from the arrival time and departure time of the work equipment, but in an environment where interruption work occurs, the time when the worker does not perform the process related to the work is also measured as the time required for the work. As a result, there is a problem that there is a discrepancy between the time the worker actually worked and the measured required time.

In the method disclosed in Patent Document 2, an ultrasonic sensor is used to measure the position of the operator's hand. It is mainly caused by computer input devices (for example, keyboard and mouse), and there are few events where the hand position leaves the keyboard. Therefore, it is difficult to calculate the movement related to the actual work of the worker and the required time using the bracelet and the sensor.

In the method disclosed in Patent Document 3, the operator inputs the work content, but inputting the work content takes time and effort, and as a result, the time the operator spends on his main job is shortened, which in turn reduces productivity. There is Furthermore, since the operator forgets to input, there is a possibility that there will be a discrepancy between the operator's actual work content and required time and the measurement result.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to enable an operator to accurately grasp the time required for work and processes, and to make it possible to plan effective measures for shortening the time required for work and processes. . Another object of the present invention is to immediately evaluate the effect of shortening the required time after implementing the measures.

In order to solve the above problems, in a work process including a plurality of tasks, there is provided a work time calculation system that calculates the work time of an operator for each work, and acquires the current position of the operator and the stay time at the current position. a standard position storage unit for storing transition information of the standard work position in the work process of the operator and transition information of the standard stay time at the standard work position; Work time calculation for calculating the work time of an operator for each work in a work process based on the current position and the stay time, and the transition information of the standard work position and the transition information of the standard stay time stored in the standard position storage unit and a device.

In sequence 600 , operator current position measuring device 110 measures the current position of operator 101 based on the sensor data received from parent device 108 . Details of the sequence 600 will be described with reference to FIG.

In sequence 506 , the operator current position measurement device 110 transmits the name, current time, and current position of the operator 101 to the operator stay position transition database 120 . Transmission protocols include TCP (Transmission Control Protocol)/IP (Internet Protocol), for example.

<Flow chart of operator's current position measurement method>
Next, the flow of processing of sequence 600 described above will be described.
FIG. 12 is a flow chart of processing for measuring the current position of the operator 101 by the operator current position measuring device 110 in the sequence 600 .

In step S101, the operator current position measuring device 110 receives the sensor serial number 302 (see FIG. 5), repeater serial number 202 (see FIG. 4), radio wave intensity, x-axis acceleration, y-axis acceleration, The z-axis acceleration and the sensor data reception time are stored in the sensor information table 116 . As an example of the sensor data received here, the data shown in FIG. 3 can be considered. When the storage in the sensor information table 116 is completed, the process proceeds to step S102.

In step S<b>102 , the operator current position measurement device 110 extracts sensor data received at the same time from the sensor information table 116 . Examples of the implementation form of the extraction method include SQL. When the extraction of sensor data is completed, the process proceeds to step S103.

In step S103, the operator current position measuring device 110 refers to the sensor data received in step S102, and selects the sensor data having the same sensor serial number 302 with the highest radio wave intensity (for example, the radio wave intensity 404 in FIG. 6). Sensor data (for example, sensor data with a radio wave intensity of 350) is extracted. The magnitude of the radio wave intensity represents the proximity between the sensor 102 and the receiver (for example, the monitoring terminal 103, work terminal A 104, work terminal B 105, reporting terminal 106). Examples of the implementation form of the extraction method include SQL. After extracting the data with the highest radio wave intensity, the process proceeds to step S104.

In step S104, the operator current position measurement device 110 refers to the repeater position information table 114, and the repeater serial number 403 of the sensor data with the highest radio wave intensity extracted in step S103 (for example, the repeater serial number 403 is " 0010001") is associated with the position 203 (see FIG. 4) where the repeaters 107A to 107D are installed. This is because it is considered that the operator carrying the sensor 102 is staying at the position of the receiver (monitoring terminal 103, for example) that provides sensor data with high radio wave intensity. As an implementation form of the matching method, for example, SQL can be used. Either step S104 or step S105 may be performed first. When the correspondence between the repeater serial number 403 of the sensor data having the highest radio wave intensity and the positions where the repeaters 107A to 107D are installed is completed, the process proceeds to step S105.

In step S105, the operator current position measuring device 110 refers to the operator/sensor correspondence table 115, and the sensor serial number 402 of the sensor data with the highest radio wave intensity extracted in step S103 (for example, the sensor serial number 402 is "1010001"). , and the operator identifier 303 (for example, the operator identifier "Hitachi Taro" corresponding to the sensor serial number "1010001").As an implementation form of the method of associating, for example, SQL, etc. Which comes first, step S104 or step S105? After completing the correspondence between the sensor serial number and the operator identifier, the process proceeds to step S106.

In step S106, the operator current position measuring device 110 receives the sensor data 401 (see FIG. 6), the operator identifier 303 (see FIG. 5) extracted in step S105, and the repeaters 107A to 107D extracted in step S104. The installation position 203 (see FIG. 4) and the x-axis acceleration, y-axis acceleration, and z-axis acceleration of the sensor data acquired in step S103 are transmitted to the operator stay position transition database 120. FIG. Examples of implementations of protocols for transmission include TCP/IP. When the transmission is completed, the process proceeds to step S107.

In step S107, the operator current position measurement device 110 refers to the sensor information table 116 (FIG. 6), determines whether unprocessed sensor data exists at the same reception time, and processes according to the result. branch. If unprocessed sensor data exists, the process proceeds to step S103. If there is no unprocessed sensor data, the process proceeds to step S108.

In step S108, the operator current position measurement device 110 refers to the sensor information table 116 (FIG. 6) to determine whether or not unprocessed sensor data exists, and branches the processing according to the result. If there is unprocessed sensor data, the process proceeds to step S102, and if there is no unprocessed sensor data, the process ends.

In this embodiment, the method of measuring the current position of the operator 101 using the maximum value of the radio wave intensity of radio waves transmitted at regular time intervals between the sensor 102 and the receiver has been described. Other methods for measuring the current position of the operator 101 include, for example, a method in which a beacon installed at the current position of the operator 101 is used to measure the length of time the operator 101 stays at the work position, , a method of extracting sensor data whose radio wave intensity is equal to or greater than a certain threshold value, a method of measuring the current position of the operator 101 with a camera, and the like. Any of these schemes may be used in actual implementation.

At 22:00, he started staying at work terminal A104. Operator 101 continues monitoring work of system A, leaves work terminal A 104 at 12:32:00 on January 1, 2018, moves to reporting terminal 106, and moves to reporting terminal 106 at 12:33:00 on January 1, 2018. It is assumed that the stay at the reporting terminal 106 is started from . It is assumed that the operator 101 finished the monitoring work of the A system at 12:37:00 on January 1, 2018.

In the operator identifier 1401, the name of the operator 101 or the operator identifier is displayed in a pull-down list, and the analyst 170 selects the name of the operator whose required work time is to be calculated from the pull-down list. Although not shown in the drawing, the operator identifier 1401 may allow selection of a plurality of operators. In that case, the processing sequences 801 to 804 may be repeated for each of a plurality of selected operators, and a screen displaying the work required time of each operator 101 may be provided.

In the work time calculation period column 1402, the analyst 170 designates the start time and end time of the period for calculating the breakdown of the work time of the operator 101 in a free form.

You may display an error message such as

The result screen 162 includes a search condition column 1411 , work required time 1412 , work breakdown column 1413 , and a return button 1414 .

The search condition column 1411 displays to the analyst the operator name and the working time calculation period that the analyst 701 has input.

The required work time 1412 displays the work performed by the specific operator 101 during the work time calculation period and the actual required time.

The work breakdown column 1413 displays the time when the specific operator 101 stayed at the work position during the work time calculation period, the name of the work he was engaged in at the work position, the work position, and the stay time at the work position.

When the operator 101 presses the return button 1414 after confirming the result screen 162 , the screen transitions to the condition input screen 161 .

Next, as shown in FIG. 14, in sequence 801, the analyst 170 inputs an operator identifier 1401 and a work time calculation period 1402 through the condition input screen 161 (see FIG. 16) in the analyst terminal 160. FIG. The operator identifier 1401 is based on the operator identifier 303 of the operator/sensor correspondence table 115 . If the operator identifier 1401 input in sequence 801 does not correspond to any of the operator identifiers 303 in the operator/sensor correspondence table 115, the analyst terminal 160 may return an error to the analyst 170. FIG.

A sequence 802 inputs an operator identifier 1401 and a work time calculation period 1402 to the work required time calculation device 140 from the condition input screen 161 (see FIG. 16) of the analyst terminal 160 . As an implementation form of the data to be transmitted, for example, JSON (Javascript (registered trademark) Object Notation) is conceivable.

In sequence 900 , the work required time calculation device 140 calculates the work breakdown and work time required for the operator 101 based on the operator identifier 1401 and the work time calculation period 1402 received from the analyst terminal 160 . Details of the sequence 900 will be described with reference to FIG.

In sequence 803 , the work required time calculation device 140 transmits the details of the operator's work and the work required time calculated in sequence 900 to the analyst terminal 160 together with the operator identifier. JSON, for example, is conceivable as an implementation form of the data to be transmitted.

In sequence 804, the required work time calculation device 140 displays the search condition 1411, work details 1413, and required work time 1412 on the result screen 162 of the analyst terminal 160 (see FIG. 16).

<Breakdown of operator's work, method of calculating work required time>
FIG. 15 shows an example of a procedure in which the required work time calculation device 140 calculates the work breakdown 1413 and the required work time 1412 of the operator 101 in the sequence 900 .

In step S201, the required work time calculation unit 141 of the required work time calculation device 140 accesses the operator stay position transition database 120, inputs the operator identifier, the analysis start time, and the analysis end time, and from the position table 121, the analysis period The work position 1002 of the operator 101 in the data, and the stay start time 1003 and stay end time 1004 at each work position are extracted. Examples of the implementation form of the extraction method include SQL. For example, in the example shown in FIG. 13, the required work time calculation unit 141 determines that the stay start time of the operator identifier "Hitachi Taro" is "January 1, 2018 12:00" from the position table 121 shown in FIG. 12:40:00 on January 1, 2018, which is a record from '12:00:00 on January 1, 2018' to 'January 1, 2018' "monitoring terminal" between "day 12:05:00" and "work terminal" between "January 1, 2018 12:06:0" Terminal B", between "12:17:00 on January 1, 2018" and "12:21:00 on January 1, 2018", "reporting terminal", "12:00 on January 1, 2018" 22:00" to "January 1, 2018 12:32:0", "Work terminal A", "January 1, 2018 12:33:0" to "January 1, 2018 'reporting terminal' is extracted during 12:40:00 on the day. After the extraction is completed, the process proceeds to step S202.

In step S202, the required work time calculation unit 141 accesses the incident information management device 130 or the incident database 131, inputs the operator identifier, the analysis start time, and the analysis end time. Extract the names of incidents that occurred within the analysis period. Examples of the implementation form of the extraction method include SQL. For example, in the example shown in FIG. 13, the required work time calculation unit 141 refers to the incident table 132 shown in FIG. 0 seconds” to “January 1, 2018, 12:40:00”, “A system monitoring” and “B system monitoring” are extracted. When the extraction in the incident database 131 is completed, the process proceeds to step S203.

In step S203, the required work time calculation unit 141 accesses the required time calculation database 142, inputs the operator identifier and the incident name extracted in step S202, and calculates the standard position 1203 and standard order 1204 of the standard work position transition table 143. , the standard staying time 1205 is obtained. For example, in the example shown in FIG. 13, the required work time calculation device 140 refers to the standard work position transition table 143 shown in FIG. '1', 'monitoring terminal', '3 minutes', related to 'A system monitoring', which is a work performed between '0:00:00' and 'January 1, 2018, 12:40:00'; '2' 'Work Terminal A' '10 minutes', '3' 'Reporting Terminal' '4 minutes' information and '1' 'Monitoring Terminal' '2 minutes' and '2' related to 'B System Monitoring' , ``work terminal B'', ``10 minutes'', ``3'', ``reporting terminal'', and ``4 minutes''. Once the standard position 1203, standard order 1204, and standard staying time 1205 have been obtained, the process proceeds to step S204.

In step S204, the required work time calculation unit 141 selects the work position 1002 (see FIG. 7) of the operator 101 extracted in step S201 and the standard position 1203 obtained in step S203 in order of the standard order 1204 obtained in step S203. compare. For example, in the example shown in FIG. 13, the work required time calculation unit 141 calculates the "monitoring terminal" which is the work position 1002 of the operator 101 extracted in step S201, and the "A system monitoring" corresponding to the standard order "1". and "monitoring terminal" of "B system monitoring". Then, the process proceeds to step S205.

In step S205, the conditions are branched depending on whether or not there are a plurality of works extracted in step S201 and the work position 1002 compared in step S204 overlaps with a plurality of standard positions 1203. FIG. If the work position 1002 overlaps with the standard positions 1203 of a plurality of works, the process proceeds to step S206. For example, in the example shown in FIG. 13, the work required time calculation unit 141 calculates the "monitoring terminal" which is the work position 1002 of the operator 101 extracted in step S201, and the "A system monitoring" corresponding to the standard order "1". and the "monitoring terminal" of "B system monitoring" are compared.

In step S<b>206 , the required work time calculation unit 141 proportionally divides the stay time at the work position 1002 in the position table 121 into the work times for each of a plurality of overlapping tasks, and outputs the result to the required work time breakdown table 151 . For example, in the example shown in FIG. 13, the "monitoring terminal" which is the work position 1002 of the operator 101 extracted in step S201, and the "monitoring terminal" and "B Since the "monitoring terminal" of the "system monitoring" is duplicated, the staying time of the "monitoring terminal", which is the work position 1002 of the operator 101, is changed from "January 1, 2018 12:00:00" to "2018 The five minutes until 12:05:00 on January 1st will be apportioned as working hours for "A system monitoring" and "B system monitoring".

The method of apportionment may be specified by the analyst 170 . Also, the method of apportionment may be a system that can be changed by the analyst 170 . For example, if the method of apportionment is defined as "ratio of standard stay time of multiple tasks", in the example shown in FIG. In order to divide the 5 minutes of "12:05:00" into the ratio of "3 minutes" for "A system monitoring" and "2 minutes" for "B system monitoring", "A system monitoring" is set to "2018 January 12:00:00 on January 1st" to "12:03:00 on January 1st, 2018", and "B system monitoring" from "12:03:00 on January 1st, 2018" to "2018 12:05:00 on January 1st". When the apportionment is completed, the process proceeds to step S207.

<How to change the apportionment method>
Here, the apportionment method storage unit 144 (see FIG. 1) defines the apportionment method for working hours, and the apportionment method can be changed as appropriate. The apportionment method is changed by the analyst 170 from the apportionment method change screen 163 of the analyst terminal 160 .

FIG. 17 is a diagram illustrating an example of the apportionment method change screen 163 of the analyst terminal 160. As shown in FIG.
FIG. 18 is a diagram illustrating the flow of changing the apportionment method by the apportionment method storage unit 144. As shown in FIG.

As shown in FIG. 17 , the apportionment method storage unit 144 displays an apportionment method change screen 163 on the analyst terminal 160 . On the apportionment method change screen 163, for example, a URL specifying the apportionment method (URL having a program specifying the apportionment method) can be input from "Specify Git repository". After the analyst 170 inputs the URL specifying the apportionment method, the apportionment method change button 1702 is selected to obtain the program specifying the apportionment method from the URL, and by executing this program, the apportionment method can be changed. Changes can be made. Also, on the apportionment method change screen 163, for example, it is possible to input the PATH and name of the folder in which the program defining the apportionment method is stored from "code registration". Analyst 170 selects apportionment method change button 1702 after inputting PATH and name from code registration, thereby acquiring a program defining apportionment method from a predetermined folder, and executing this program to change apportionment method. changes can be made.

As shown in FIG. 18, in sequence 1801, the analyst 170 inputs the location of the source code of the program implementing the apportionment method from the apportionment method change screen 163 of the analyst terminal 160 described above.

In sequence 1802, the apportionment method storage unit 144 refers to the location of the source code of the program input by the analyst 170 and acquires the source code.

In sequence 1803, the apportionment method storage unit 144 registers the source code acquired in step S1802.

In sequence 1804 , the apportionment method storage unit 144 transmits a registration completion message to the apportionment method change screen 163 .

In sequence 1805 , the apportionment method change screen 163 displays a registration completion message to the analyst 170 .

As described above, the user such as the analyst 170 can appropriately change the apportionment method in accordance with the status of the information system, so apportionment can be performed appropriately.

Returning to FIG. 15, in step S207, the required work time calculation device 140 branches the condition depending on whether the comparison between the work position 1002 of the position table 121 and the standard position 1203 of the standard work position transition table 143 is completed. If not completed, the process returns to step S204. For example, in the example shown in FIG. 13, the comparison between the work position 1002 of the operator 101 extracted in step S201 and the standard position 1203 has not been completed, so the process returns to step S204.

For example, in the case shown in FIG. 13, the required work time calculation device 140 returns to step S204, and corresponds to "work terminal B", which is the work position of the operator 101 extracted in step S201, and standard order "2". "Work terminal A" in "A system monitoring" and "Work terminal B" in "B system monitoring" are compared. Then, the process proceeds to step S205.

In step S205, the work required time calculation device 140 extracts "work terminal B", which is the work position of the operator 101 extracted in step S201, and "work terminal A" of "A system monitoring" corresponding to the standard order "2". and "work terminal B" of "B system monitoring" are compared, and since there is no duplication, the process proceeds to step S208.

In step S<b>208 , the required work time calculation device 140 inputs the stay time at the work position extracted in step S<b>201 to the required work time breakdown table 151 of the required work time database 150 as the time required for the work. For example, in the example shown in FIG. 13, the staying time of “work terminal B” from “January 1, 2018 12:06:00” to “January 1, 2018 12:16:00” is , as the required time of "B system monitoring", "12:06:00 on January 1, 2018", "12:16:00 on January 1, 2018" and the difference of 10 minutes, It is input to the work required time breakdown table 151 as the required time for "B system monitoring". When the input is completed, the process proceeds to step S208.

Hereinafter, in the example shown in FIG. 13, the comparison between the work position 1002 and the standard position 1203 is repeated, and when the comparison ends in step S207, the required work time calculation device 140 ends the processing.

<How to update the standard work position update table>

On the standard work position transition table update period designation screen 1901, it is possible to select whether the standard work position transition table 143 is to be updated automatically or manually. When automatic update is selected, the automatic update cycle can be set by inputting an update cycle (for example, 3 months). Also, when manual update is selected, the time for manual update can be set by inputting the start time and end time. As a result, the contents of the standard work position transition table 143 (for example, the standard stay time 1205) can be appropriately updated according to the work proficiency level of the operator 101, and the work time can be calculated more accurately. can be done.

In the standard work position transition table registration screen 1902, new work can be added when new work occurs. For the work name, enter the newly generated work (for example, B system housekeeping). For the operator identifier, enter the identifier of the operator who performs the work (for example, Hanako Hitachi). The order of the work, the work position, and the work position stay time are entered in the position stay time field. Furthermore, by adding a line, it is possible to add work.

By selecting the standard work position transition table update start button 1903, the standard work position transition table 143 is updated with the contents set in the standard work position transition table update period designation screen 1901 and the standard work position transition table registration screen 1902 described above. can be updated.

Next, as shown in FIG. 20, in sequence 2001, the analyst 170 selects the update period or update cycle of the standard work position transition table 143 from the update screen 164 of the standard work position transition table of the analyst terminal 160, or the new work , operator identifier, standard work position, standard sequence, work position cleaning time.

Then, in sequences 2002 and 2003, the standard work position transition table update unit 145 updates the input standard work position transition table 143 update period or update cycle, or new work, operator identifier, standard work position, standard order, work position. Register update information such as detergent time.

In sequence 2004 , the standard work position transition table update unit 145 sends an update completion message to the standard work position transition table update screen 164 .

In sequence 2005, an update completion message is displayed on the update screen 164 of the standard work position transition table.

According to the work time calculation system 1 according to the present embodiment, based on information on the standard work position for each work of the operator 101 shown in FIG. By calculating the time required for the work compared with the transition of the work position, it is possible to accurately calculate the actual time required for the work even in an environment where work is interrupted.
