Description

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

  In recent years, with the declining birthrate and aging population, the working-age population has decreased, and it is urgently necessary to improve productivity in various working environments. To improve productivity, it is necessary to visualize the current state of worker productivity and identify the factors that reduce productivity.

  For example, even at the operation site of an information system, the behavior of a worker (hereinafter, referred to as an operator) in charge of operation uses a sensor (for example, an acceleration sensor or a biological information sensor) and an incident management system (for example, Redmine or ServiceNow). By collecting and visualizing it, it is possible to calculate the time required for the worker's work.

  In Patent Document 1, the time required for a worker working in an office to reach a work device and the time the work device leaves the work device are measured, and the difference between those times is calculated to calculate the time required for the work excluding the time for leaving the work. A technique for visualizing the gender has been disclosed.

  Patent Literature 2 discloses a method of 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 contents at which work (such as taking out a product from a shelf) is performed without the worker himself / herself inputting work information.

  Patent Literature 3 introduces an example in which a worker carries a sensor to collect and visualize work content input by a worker in order to formulate a measure for improving productivity.

Japanese Patent Application No. 2008-189323 US2017278051 Japanese Patent Application No. 2006-222484

  However, in the method disclosed in Patent Literature 1, the leaving time of the operator is calculated, but when the operator transitions between a plurality of work places and the transition is related to the work (for example, from a terminal receiving a customer inquiry, In the case of moving to another terminal to actually perform the work and moving to another terminal to notify the customer of the work result after the work is completed, etc.), it is determined that the leaving time is not related to the main business Therefore, there is a possibility that a difference occurs between the operation time of the operator excluding the leaving time and the time required for the actual operation of the operator. Further, in an environment where a worker himself / herself can perform a plurality of works at the same time, an interruption work (an act of interrupting the work that the worker was engaged in and starting another work) occurs. In Patent Literature 1, the required time of the work is calculated from the arrival time and the departure time of the work equipment. However, in an environment where an interrupting work occurs, the time during which the worker does not perform a process related to the work is also measured as the required time of the work. As a result, there is a problem that a difference occurs between the time actually worked by the worker and the measured required time.

  In the method disclosed in Patent Literature 2, the position of an operator's hand is measured using an ultrasonic sensor. However, in an environment such as an office in charge of operation of an information system, the movement of a worker's hand related to the operation is This is mainly due to the input devices of the computer (for example, a keyboard and a mouse), and the event that the position of the hand leaves the keyboard is rare. Therefore, it is difficult to calculate the operation related to the actual work of the worker and the required time using the bracelet and the sensor.

  In the method disclosed in Patent Literature 3, the operator inputs the work content, but the input of the work content is troublesome, and the time required for the operator to work in the main business is shortened, resulting in a decrease in productivity. There is. Further, since the operator forgets to input, there is a possibility that a difference occurs between the actual work content of the operator and the required time and the measurement result.

  Therefore, an object of the present invention is to grasp the exact time required for an operation and a process of an operator, and to be able to use it for planning an effective measure for shortening the time required for the operation and the process. . It is another object of the present invention to be able to immediately evaluate the effect of reducing the required time after implementing a measure.

  In order to solve the above-mentioned problem, in a work process including a plurality of works, a work time calculation system for calculating the work time of an operator in each work, the system acquires an operator's current position and a stay time at the current position A current position measuring device, a standard position storage unit for storing transition information of a standard work position in a work process of an operator, and transition information of a standard stay time at the standard work position, and a current position measurement device obtained by the current position measuring device. Work time calculation for calculating the work time of the operator in each work in the 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.

  ADVANTAGE OF THE INVENTION According to this invention, the exact time required for an operation | work and process of an operator can be grasped | ascertained, and it can be used for planning of an effective measure for shortening the time required for an operation | work and process. Furthermore, the effect of shortening the required time can be immediately evaluated after implementing the measures.

FIG. 11 shows a process in which the parent device 108 receives sensor data transmitted between the sensor 102 and the relay device 107A or 107B, and transmits a radio wave received by the parent device 108 to the operator current position measuring device. 10 shows a flow of processing assuming that the operator current position measuring device 110 determines the current position of the operator 101 based on the sensor data transmitted to the base unit 108 and received from the master unit 108 and stores the current position of the operator 101 in the operator staying position transition database 120. .

  As shown in FIG. 11, in the sequences 501 and 502, the sensor 102 includes information on the x-axis acceleration, the y-axis acceleration, the z-axis acceleration of the sensor 102, and the serial number of the sensor 102 in the repeater 107 A or 107 B. Transmit radio waves. The radio wave is transmitted by, for example, Zigbee, BLE (Bluetooth (registered trademark) Low Energy), or Wi-Fi protocol. An example of the sensor data transmitted here is data obtained by removing the serial numbers of the repeaters 107A, 107B, 107C, and 107D from the sensor data 1501 shown in FIG.

  In sequences 503 and 504, the repeater 107A or the repeater 107B determines the serial number of the sensor 102, the serial number of the repeater 107A or the repeater 107B, the radio wave intensity, the x-axis acceleration, and the y-axis based on the radio wave received from the sensor 102. A radio wave including information on acceleration and z-axis acceleration is transmitted to base unit 108. The radio wave is transmitted by, for example, Zigbee, BLE, or Wi-Fi protocol. As an example of the sensor data transmitted here, the sensor data 1501 shown in FIG. 3 can be considered.

  In sequence 505, base unit 108 determines the serial number of sensor 102, the serial number of repeater 107A or repeater 107B, the radio wave intensity, the x-axis acceleration, and the y-axis acceleration based on the radio wave received from repeater 107A or repeater 107B. , And z-axis acceleration information to the operator current position measuring device 110. The parent device 108 and the operator current position measuring device 110 may be implemented on the same computer. The communication method between the parent device 108 and the operator current position measuring device 110 is, for example, serial communication.

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

  In a sequence 506, the operator current position measuring apparatus 110 transmits the name, current time, and current position of the operator 101 to the operator stay position transition database 120. The transmission protocol includes, for example, a Transmission Control Protocol (TCP) / Internet Protocol (IP).

<Flowchart of operator's current position measurement method>
Next, the flow of the process of the above-described sequence 600 will be described.
FIG. 12 is a flowchart of a process in which the operator current position measuring device 110 measures the current position of the operator 101 in the sequence 600.

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

  In step S102, the operator's current position measuring device 110 extracts sensor data received at the same time from the sensor information table 116. As an implementation form of the extraction method, for example, SQL or the like is cited. When the extraction of the sensor data is completed, the process proceeds to step S103.

  In step S103, the operator's current position measuring device 110 refers to the sensor data received in step S102, and selects a higher signal strength (for example, the signal strength 404 in FIG. 6) from the sensor data of the same sensor serial number 302. Sensor data (for example, sensor data with a radio field intensity of 350) is extracted. The magnitude of the radio wave intensity indicates the proximity of the sensor 102 and the receiver (for example, the monitoring terminal 103, the work terminal A104, the work terminal B105, and the report terminal 106). As an implementation form of the extraction method, for example, SQL or the like is given. When the data having the highest radio field intensity is extracted, the process proceeds to step S104.

  In step S104, the operator current position measuring apparatus 110 refers to the repeater position information table 114 and refers to the repeater serial number 403 of the sensor data having the highest radio field intensity extracted in step S103 (for example, if the repeater serial number 403 is " 0010001 ") and 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 (for example, the monitoring terminal 103) that becomes the sensor data having the strong radio wave intensity. As an implementation form of the associating method, for example, SQL or the like is cited. Either step S104 or step S105 may be performed first. When the association between the repeater serial number 403 of the sensor data having the highest radio field 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 apparatus 110 refers to the operator / sensor correspondence table 115, and detects the sensor serial number 402 of the sensor data having the highest radio field intensity extracted in step S103 (for example, the sensor serial number 402 is "1010001". (For example, the operator identifier “Taro Hitachi” corresponding to the sensor serial number “1010001”), for example, as an implementation form of the method such as SQL, etc. Which of the steps S104 and S105 is the first. When the association between the sensor serial number and the operator identifier is completed, the process proceeds to step S106.

  In step S106, the operator current position measuring apparatus 110 determines the time 401 (see FIG. 6) at which the sensor data was received, the operator identifier 303 extracted in step S105 (see FIG. 5), and the repeaters 107A to 107D extracted in step S104. The installed 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. An example of the implementation form of the protocol to be transmitted is TCP / IP. When the transmission is completed, the process proceeds to step S107.

  In step S107, the operator current position measuring device 110 refers to the sensor information table 116 (FIG. 6), determines whether or not unprocessed sensor data exists at the same reception time, and performs processing according to the result. Branch. If there is unprocessed sensor data, the process proceeds to step S103. If there is no unprocessed sensor data, the process proceeds to step S108.

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

  In the present embodiment, a method has been described in which the current position of the operator 101 is measured using the maximum value of the radio wave intensity of radio waves transmitted at fixed time intervals between the sensor 102 and the receiver. Other methods for measuring the current position of the operator 101 include, for example, a method of measuring the stay time of the work position of the operator 101 using a beacon installed at the current position of the operator 101, and a method of measuring the stay time of the operator 101 between the sensor 102 and the receiver. For example, a method of extracting sensor data in which the radio wave intensity of the radio wave is equal to or more than a predetermined threshold, a method of measuring the current position of the operator 101 with a camera, and the like are considered. In an actual implementation, any of these methods may be used.

<Process flow when there is interrupt work>
FIG. 13 shows an example of the transition of the position when a specific operator performs an interruption work in the present embodiment. Hereinafter, in the present embodiment, processing will be described based on the example of FIG. In the present embodiment, the specific operator 101 (for example, Hitachi Taro) started monitoring the A system at 12: 00: 00: 00 on January 1, 2018, and started staying at the monitoring terminal 103. The operator 101 continued the work at the monitoring terminal 103, but the work of monitoring the B system was interrupted at 12:03:01 on January 1, 2018, so the work of monitoring the B system was interrupted by the work of monitoring the A system. Has started. The operator 101 suspends the monitoring work of the A system and continues the monitoring work of the B system, leaves the monitoring terminal 103 at 12:05:01 on January 1, 2018, moves to the work terminal B105, and At 12:06:01 on January 1, stay at the work terminal B105 was started. The operator 101 continues the work at the work terminal B105, leaves the work terminal B at 12: 16: 00: 00 on January 1, 2018, moves to the report terminal 106, and moves to the report terminal 106 at 12: 17: 00: 00 on January 1, 2018. At the reporting terminal 106. The operator 101 ends the monitoring work of the system B at 12: 21: 00: 00 on January 1, 2018, and moves to the work terminal A104 to return to the monitoring work of the system A. At 22 minutes and 0 seconds, stay at the work terminal A104 was started. The operator 101 continues the monitoring work of the A system, leaves the work terminal A 104 at Jan. 1, 2018 at 12:32. It is assumed that the stay at the reporting terminal 106 has been started. It is assumed that the operator 101 has completed the monitoring work of the system A at 12: 37: 0 on January 1, 2018.

<Work required time calculation method>
FIG. 14 shows the current position of the operator 101, the staying time at the current position, the work content, and the standard required time of the work content in the work required time calculation device 140 so that the analyst can know the required work time of the operator 101 in this embodiment. FIG. 5 is a schematic diagram illustrating an outline of an operation for calculating a required work time by utilizing the information of FIG. FIG. 14 shows a flow of a process in which the required work time calculation device 140 calculates the required work time of the operator 101 based on the data input to the analyzer terminal 160 by the analyst 170 and outputs the calculated work required time to the analyzer terminal 160.
FIG. 16 is a diagram illustrating an example of the condition input screen 161 and the result screen 162.

First, in FIG. 16, the condition input screen 161 includes an operator identifier 1401, a work time calculation period field 1402, and a work required time calculation start button 1403.
In the operator identifier 1401, the name of the operator 101 or the operator identifier is displayed in a pull-down manner, and the analyst 170 selects an operator name for calculating the workplace time from the pull-down list. Although not shown in the drawing, a plurality of operators may be selectable by the operator identifier 1401. In this case, a processing screen for displaying the required time of each operator 101 may be provided by repeating the processing sequences 801 to 804 for each of the selected plurality of operators.

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

  The work required time calculation start button 1403 is pressed after the analyst 170 inputs the operator name or identifier in the operator identifier 1401 and the start time and end time of the period for calculating the breakdown of the work time in the work time calculation period field 1402. Then, a request for calculating the work time breakdown is transmitted to the work required time calculation device 140. When the operator presses the required work time calculation start button 1403 in a state where either the start time or the end time of the period for calculating the breakdown of the operator name and the work time is insufficient, "the data for calculation is insufficient. An error message such as "" may be displayed.

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

  The search condition column 1411 displays the operator name and the work time calculation period input by the analyst 701 to the analyst.

  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 at which the specific operator 101 stayed at the work position during the work time calculation period, the name of the work performed at the work position, the work position, and the stay time at the work position.

  When the operator 101 confirms the result screen 162 and presses the return button 1414, the screen transits to the condition input screen 161.

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

  In the sequence 802, the operator identifier 1401 and the work time calculation period 1402 are input to the work required time calculation device 140 from the condition input screen 161 (see FIG. 16) of the analyzer terminal 160. As an implementation form of the data to be transmitted, for example, JSON (JavaScript (registered trademark) Object Notation) can be considered.

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

  In a sequence 803, the required work time calculation device 140 transmits the details of the work of the operator and the required work time calculated in the sequence 900 to the analyzer terminal 160 together with the operator identifier. As an implementation form of the data to be transmitted, for example, JSON can be considered.

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

<Breakdown of operator's work and calculation of required work time>
FIG. 15 shows an example of a procedure in which the required work time calculation device 140 calculates a work breakdown 1413 and a 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 an operator identifier, an analysis start time, and an analysis end time. The work position 1002 of the operator 101, the stay start time 1003 and the stay end time 1004 at each work position are extracted. As an implementation form of the extraction method, for example, SQL or the like is cited. For example, in the example illustrated in FIG. 13, the work required time calculation unit 141 determines from the position table 121 illustrated in FIG. 7 that the stay start time of the operator identifier “Taro Hitachi” is “12:00 on January 1, 2018”. From “minutes 0 seconds” to the end time of stay “12: 40: 00: 00 on January 1, 2018”, from “12: 00: 00: 00 on January 1, 2018” to “January 1, 2018” "Monitoring terminal" during the day 12: 5: 0 "and" Working "between" January 1, 2018 12: 6: 0 "and" January 1, 2018 12: 16: 0 " “Terminal B”, “Reporting terminal” between “Jan. 1, 2018 12: 17: 0” and “Jan. 1, 2018 12: 21: 0”, “Jan. 1, 2018 12:00” Between "22:02" and "12: 32: 00: 00 on January 1, 2018", "work terminal A", "2018 To extract the "report terminal" between January 1, from 12 o'clock 33 minutes 0 seconds "of" January 1, 12 hours 40 minutes 0 seconds 2018 ". When 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 apparatus 130 or the incident database 131, inputs an operator identifier, an analysis start time, and an analysis end time, and the operator 101, which exists in the incident table 132, Extract the names of the incidents performed during the analysis period. As an implementation form of the extraction method, for example, SQL or the like is cited. For example, in the example illustrated in FIG. 13, the work required time calculation unit 141 refers to the incident table 132 illustrated in FIG. 8, and indicates that the operator identifier “Hitachi Taro” is “12:00 on January 1, 2018. “A system monitoring” and “B system monitoring”, which are operations performed between “0 second” and “12: 40: 00: 00 on January 1, 2018”, 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 enters the standard position 1203, the standard order 1204 of the standard work position transition table 143. , The standard stay time 1205 is acquired. For example, in the example shown in FIG. 13, the work required 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 was performed between "hours 0 minutes 0 seconds" and "12: 40: 00: 00 on January 1, 2018" Information of “2” “work terminal A” “10 minutes”, “3” “report terminal” “4 minutes”, and “1” “monitoring terminal” “2 minutes” and “2” related to “B system monitoring” Information such as “work terminal B” “10 minutes”, “3” “report terminal” “4 minutes” is extracted. After acquiring the standard position 1203, the standard order 1204, and the standard stay time 1205, the process proceeds to step S204.

  In step S204, the required work time calculation unit 141 determines, in the order of the standard order 1204 acquired in step S203, the work position 1002 (see FIG. 7) of the operator 101 extracted in step S201 and the standard position 1203 acquired in step S203. Compare. For example, in the example illustrated in FIG. 13, the required work time calculation unit 141 includes 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”. Of "monitoring terminal" of "monitoring terminal" and "monitoring terminal" of "B system monitoring" are compared. Then, the process proceeds to step S205.

  In step S205, the condition is branched depending on whether a plurality of works extracted in step S201 exist and the work position 1002 to be compared in step S204 overlaps with a plurality of standard positions 1203. 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 illustrated in FIG. 13, the required work time calculation unit 141 includes 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”. Is compared with the "monitoring terminal" of "B system monitoring". Since the "monitoring terminal" is duplicated, the process proceeds to step S206.

  In step S206, the required work time calculator 141 apportions the stay time of the work position 1002 in the position table 121 to the work times of a plurality of overlapping works and outputs the work time breakdown table 151. For example, in the example illustrated in FIG. 13, the “monitoring terminal” that is the work position 1002 of the operator 101 extracted in step S201, and the “monitoring terminal” and “B” of “A system monitoring” corresponding to the standard order “1” Since the “monitoring terminal” of “system monitoring” overlaps, the stay time of the “monitoring terminal”, which is the working position 1002 of the operator 101, is “12:00, January 1, 2018 12:00:00” to “2018”. The five minutes until 12:05:02 on January 1 are apportioned as work times for "A system monitoring" and "B system monitoring".

  The apportioning method may be specified by the analyst 170. Further, the apportioning method may be a system that can be changed by the analyst 170. For example, if the apportioning method is defined as “the ratio of the standard stay time of a plurality of works”, in the example shown in FIG. 13, “January 1, 2018 12:00:00” to “January 1, 2018” In order to divide the five minutes of day 12:05:02 into the ratio of “3 minutes” of “A system monitoring” and “2 minutes” of “B system monitoring”, “A system monitoring” "Monday 12: 00: 00: 00" to "January 1, 2018 12: 3: 0", and "System B monitoring" from "January 1, 2018 12: 03: 0" to "2018 "12:05:02 on January 1". When the apportionment is completed, the process proceeds to step S207.

<How to change the apportionment method>
Here, the apportioning method storage section 144 (see FIG. 1) defines the apportioning method of the work time, and can appropriately change the apportioning method. The change of the apportionment method is performed 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 apportioning method change screen 163 of the analyzer terminal 160.
FIG. 18 is a diagram for explaining the flow of changing the apportioning method by the apportioning method storage unit 144.

  As shown in FIG. 17, the apportioning method storage unit 144 displays the apportioning method change screen 163 on the analyzer terminal 160. In the apportionment method change screen 163, for example, a URL that specifies the apportionment method (URL where a program that specifies the apportionment method) can be input from “Git repository specification”. After the analyst 170 inputs the URL defining the distribution method, the user selects a distribution method change button 1702 to obtain a program defining the distribution method from the URL, and execute this program to execute the distribution method. Changes can be made. Further, on the apportioning method change screen 163, for example, a PATH and a name (Name) of a folder in which a program specifying the apportioning method is stored can be input from “Code Registration”. After the analyst 170 inputs the PATH and the name from the code registration and selects the apportioning method change button 1702, a program that defines the apportioning method is obtained from a predetermined folder, and this program is executed to execute the apportioning 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 distribution method from the distribution method change screen 163 of the analyzer terminal 160 described above.

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

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

  In sequence 1804, apportioning method storage section 144 transmits a registration completion message to apportioning method change screen 163.

  In sequence 1805, a registration completion message is displayed to analyst 170 on apportioning method change screen 163.

  As described above, the user such as the analyst 170 can appropriately change the apportioning method according to the status of the information system, so that apportionment can be performed appropriately.

  Returning to FIG. 15, in step S207, the required work time calculation device 140 branches the condition based 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 has been completed. If not completed, the process returns to step S204. For example, in the example shown in FIG. 13, since the comparison between the work position 1002 of the operator 101 extracted in step S201 and the standard position 1203 has not been completed, the process returns to step S204.

  For example, in the case shown in FIG. 13, the work required 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 the standard order “2”. A comparison is made between “work terminal A” of “A system monitoring” and “work terminal B” of “B system monitoring”. Then, the process proceeds to step S205.

  In step S205, the required work time calculation device 140 determines “work terminal B”, which is the work position of the operator 101 extracted in step S201, and “work terminal A” in “A system monitoring” corresponding to the standard order “2”. And “work terminal B” of “B system monitoring”. Since there is no overlap, the process proceeds to step S208.

  In step S208, the required work time calculation device 140 inputs the stay time of the work position extracted in step S201 as the required time of the work into the required work time table 151 of the required work time database 150. For example, in the example shown in FIG. 13, the stay time of “work terminal B” from “January 1, 2018 12: 6: 0” to “January 1, 2018 12: 16: 0” is , Assuming the time required for “B system monitoring”, “January 1, 2018 12: 6: 0”, “January 1, 2018 12: 16: 0”, and the difference of 10 minutes, The required time of “B system monitoring” is input to the required work time breakdown table 151. 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 is completed in step S207, the work required time calculation device 140 ends the processing.

<How to update the standard work position update table>
In the above-described embodiment, the standard work position transition table 143 (for example, the standard stay time 1205) may be updated based on the proficiency of the work of the operator 101. In the work time calculation system 1 according to the embodiment, the standard work position transition table update unit 145 (see FIG. 1) updates the standard work position transition table 143. Next, a method of updating the standard work position transition table 143 by the standard work position transition table update unit 145 will be described.

FIG. 19 is a diagram illustrating an update screen 164 of the standard work position transition table 143.
FIG. 20 is a diagram illustrating a method of updating the standard work position transition table 143 by the standard work position transition table update unit 145.

  As shown in FIG. 19, the standard work position transition table update screen 164 includes a standard work position transition table update period designation screen 1901 and a standard work position transition table registration screen 1902.

  On the standard work position transition table update period designation screen 1901, it is possible to select whether to update the standard work position transition table 143 automatically or manually. When the automatic update is selected, the automatic update cycle can be set by inputting the update cycle (for example, three months).
