Description

This application relates to an information processing device and a real-time work time management system.

Conventional work time management equipment calculates the difference between the time required for a task and a predetermined standard work time, and notifies the person in charge of the task by issuing a warning (see, for example, Patent Document 1).

JP 2014-016798 A (page 14, Figure 1)

The technology shown in Patent Document 1 requires that a predetermined standard work time be set before work begins. In order to set a predetermined standard work time, the standard work time needs to be measured in advance, which requires a dedicated measurer to measure the standard work time, and there are problems with the need to measure the standard work time multiple times, which requires time-consuming advance preparation. There are also problems with the lack of a mechanism for providing feedback on the worker's work time, and although an alarm can be issued if the standard work time is exceeded, there is no mechanism for immediate correction.

This application discloses technology to solve the problems described above, and aims to provide an information processing device that can automatically set appropriate standard work hours by saving the actual work hours of workers, and can send a work delay notification to the person in charge of work if a worker is working beyond the specified work hours, and can also manage work hours in real time even when work is in progress.

The information processing device disclosed in the present application comprises:
An information processing device for managing work hours obtained through an information input/output/display device that inputs/outputs and displays information,
an actual work time acquisition unit that calculates work time based on work information including work content information and worker information of the work acquired via the information input/output and display device, and acquires and stores the work time as actual work time;
a task-specific actual work time recording unit that records the actual work time for each task based on the actual work time acquired by the actual work time acquisition unit;
an individual actual work time recording unit that records the actual work time for each worker based on the actual work time acquired by the actual work time acquisition unit;
a standard work time calculation unit that calculates a standard work time including an average value and a standard deviation of all data of the actual work time based on the actual work time acquired by the actual work time acquisition unit, and calculates standard work times at a stage when the entire work is completed and at a stage during the work when part of the work is completed ;
an evaluation unit that calculates the actual work time acquired by the actual work time acquisition unit based on the standard work time calculated by the standard work time calculation unit and evaluates the calculation result;
an output unit that outputs a calculation result including warning information to be output when a preset threshold value is exceeded, which is evaluated by the evaluation unit, to the information input/output/display unit;
The present invention is characterized by comprising:

According to the information processing device disclosed in this application, the actual work time values obtained in the past are stored in a database, and the optimal standard work time is automatically set. If a worker is working beyond the standard work time, a work delay notification is sent to the person in charge of the work, making it possible to manage work in real time to reduce wasted work time even when the work is in progress.

Embodiment 1.
A real-time operation time management system according to a first embodiment will be described below with reference to FIG.
FIG. 1 is a block diagram showing a real-time work time management facility 100 that manages work time in real time for non-standardized work (hereinafter referred to as non-standardized work) such as in periodic inspections of nuclear power plants or thermal power plants, or standardized work (hereinafter referred to as standardized work) on a factory line.

In FIG. 1, the real-time work time management equipment 100 is composed of an information input/output/display 1, which is a portable device such as a tablet terminal that a worker or a work manager can use to work in a nearby location, and an information processing device 2 having a means for recording the work time of the worker when work start information and work completion information are input to the information input/output/display 1, a means for notifying the worker or the work manager that wasted time has occurred, and a means for recording the actual work time input to the information input/output/display 1 (hereinafter also referred to as actual work time; it is derived based on the work start information, work completion information, and wasted time input by the worker).

Here, the information input/output/display unit 1 is an apparatus equipped with a function for selecting a worker or work content and inputting information relating to the start and completion of work, such as the start time and completion time of the work, for each worker, and a function for displaying the occurrence of wasted time in work, and is a device equipped with a portable function that can be carried around by a worker or a work manager, etc.
In addition, as shown in Fig. 1, a plurality of the information input/output display devices 1 are usually connected to the outside of one information processing device 2. This is because the support device needs to be shared and used by a number of workers.

The information processing device 2 includes an actual work time acquisition unit 3 that calculates and acquires actual work time from the information on the start of the work of the worker and the information on the completion of the work obtained through the information input/output and display device 1, a standard work time calculation unit 4 that calculates the standard actual work time of the worker from the acquired actual work time, an evaluation unit 5 that evaluates various actual work times based on the calculated standard work time and the acquired individual actual work times, a task-specific actual work time recording unit 6 that records the above actual work time for each task, an individual actual work time recording unit 7 that records the actual work time for each worker, and an output unit 8 that outputs processed information to the outside. It is a device that has functions such as recording and calculating the information input/output using the information input/output and display device 1 and outputting an alarm, and is one of the main elements that constitute the real-time work time management facility 100. Each unit that constitutes this information processing device 2 is equipped with a database that records and stores related data of each unit (not shown).

Then, the worker and the work content are selected in the information input/output/display device 1, and the start information of the work for each worker, the completion information of the work, and other information are input. The actual work time obtained as a result is recorded and acquired in the actual work time acquisition unit 3. The actual work time acquired by the actual work time acquisition unit 3 is stored in the task-specific actual work time recording unit 6, in which the actual work time is recorded for each work (separated by the work content), and in the individual actual work time recording unit 7, in which the actual work time is recorded for each worker. The actual work time stored in the task-specific actual work time recording unit 6 is sent to the standard work time calculation unit 4. Based on the stored actual work times, the standard work time calculation unit 4 obtains the distribution of the actual work times of each work to be managed and the overall work, and calculates the average value, and based on this, automatically sets the standard work time for each work and the overall work. The actual work time is calculated based on the start time of the work included in the start information of the work, the completion time of the work included in the completion information of the work, and the rest time of the worker included in other information.

The actual work time acquired by the actual work time acquisition unit 3 and the standard work time created by the standard work time calculation unit 4 are sent to the evaluation unit 5. The evaluation unit 5 compares the actual work time acquired by the actual work time acquisition unit 3 with the standard work time calculated by the standard work time calculation unit 4, and if a preset threshold is exceeded, it passes warning information to the output unit 8. The output unit 8 outputs the information as warning information to the information input/output/display unit 1, thereby notifying the work manager who possesses the information input/output/display unit 1, thereby achieving real-time management of wasted time. Here, the standard work time includes not only the standard work time at the stage when the entire work is completed, but also the standard work time at a stage in the middle of the work when some of the work is completed.

In addition, by utilizing the actual work time accumulated in the individual actual work time recording unit 7, it is possible to check the progress of the actual work time of an unskilled worker (hereinafter also referred to as an unskilled worker) who is unfamiliar with a given task, or to calculate the difference in work time between the unskilled worker and a skilled worker (hereinafter also referred to as a skilled worker) in the evaluation unit 5 and display it on the information input/output/display unit 1 via the output unit 8. This function makes it possible to use the real-time work time management equipment 100 according to the first embodiment as a training facility or a training facility for unskilled workers who are unfamiliar with the task. Each component will be explained in more detail below using figures.

Figure 2 shows the details of the task-specific actual work time recording section 6. This figure shows the details of the task-specific actual work time recording section 6 when there are a total of five types of tasks. The actual work time for task A 61 to task E 65 are each recorded and saved separately.

The standard work time calculation unit 4 has at least two types of data, as shown in Fig. 3 (Fig. 3A, Fig. 3B). That is, it has data calculated from the standard work time for each task, as shown in Fig. 3A, and data on the distribution of actual work times calculated from all acquired data (data on all acquired actual work times), as shown in Fig. 3B. Here, the point where the value of the horizontal axis σ (here σ indicates standard deviation; more details will be described later) is zero is the average value of all the data, and the actual work time that is this average value (the average value) corresponds to the standard work time. Note that this standard work time can be changed at any time by adding data.

First, the contents of Fig. 3A showing data on calculated standard work times for each task will be described. As shown in Fig. 3A, it is assumed that the task consists of five tasks, task A to task E, according to the task procedure.
Here, task A information 41 stores data on the standard work time TS1 for the first task A. Task B information 42 stores data on the standard work time TS2 for the second task B. Task C information 43 stores data on the standard work time TS3 for the third task C. Task D information 44 stores data on the standard work time TS4 for the fourth task D. Task E information 45 stores data on the standard work time TS5 for the fifth task E.

Next, the contents of FIG. 3B will be described. FIG. 3B shows the distribution of real work time, in other words, the distribution of proficiency. This FIG. 3B is a diagram for explaining the distribution of workers into skilled workers, ordinary workers, and unskilled workers based on a normal distribution (a distribution with a mean value of zero (shown on the horizontal axis), a variance of σ ² , in other words, a standard deviation of σ) for real work time, assuming that the real work time is normally distributed. That is, based on the total time of the real work time from the work A information 41 to the work E information 45, a worker whose real work time belongs to a region with less work time (the region shown by the hatched region Sf in FIG. 3B, i.e., a region where σ is 1 or more) is defined as a skilled worker, a worker whose real work time belongs to a region with more work time (the region shown by the hatched region Su in FIG. 3B, i.e., a region where σ is -1 or less) is defined as an unskilled worker, and a worker whose real work time belongs to the other region, i.e., a region where σ is greater than -1 and less than 1 is defined as an ordinary worker (similar below).

The individual actual work time recording unit 7 has data on individual actual work times divided into at least three types. That is, as shown in FIG. 4, data on the work time 71 of the unskilled worker, data on the work time 72 of the ordinary worker, and data on the work time 73 of the skilled worker.

Furthermore, FIG. 5 is another example of the task-specific real work time recording section, and shows the details of the composite real work time recording section 9, which combines the data of FIG. 2 and FIG. 4 and has data in which the real work time for each task is further classified according to the skill level of the worker. The information processing device 2 may have the composite real work time recording section 9 shown in FIG. 5 instead of the task-specific real work time recording section 6. In FIG. 5, the real work times for each of a plurality of tasks, i.e., the real work time for task A 91, the real work time for task B 92, the real work time for task C 93, the real work time for task D 94, and the real work time for task E 95, have data stored separately as sub-classification items of each data, for example, the work time for unskilled workers 911, the work time for ordinary workers 912, and the work time for skilled workers 913, which are shown as sub-classification items of the real work time for task A in the figure. Note that here too, the skill level of the worker is determined according to the skill level standard determined based on the total real work time data described in FIG. 3.

Next, the operation of the real-time work time management equipment 100 that manages wasted time in real time according to the first embodiment will be described with reference to the flowcharts shown in Figs. 6 to 8. Here, Fig. 6 is a flowchart for explaining the operation of detecting wasteful work and warning the person in charge of work, and the operation of resetting the standard work time related to this operation, and Fig. 7 is a flowchart for explaining the operation of analyzing the target work, finding waste, and improving the actual work time.

First, the flow chart shown in FIG. 6 will be described in the order of operations.
First, in step ST1, by operating the information input/output/display device 1 (inputting the start and end of work), the actual work time acquisition unit 3 acquires the actual work time, and the standard work time calculation unit 4 creates a standard work time for the entire work.

Next, in step ST2, the evaluation unit 5 compares the standard work time and the actual work time obtained above to determine whether they are greater than a preset threshold (step ST3). If they exceed this threshold, the process proceeds to step ST4, which will be described below, and if the actual work time is equal to or less than the standard work time threshold, the process proceeds to step ST5.

Here, the threshold value may be, for example, the actual work time corresponding to σ=-1 in FIG. 3B. Although the above description assumes a standard time for the entire work, the present invention is not limited to this, and may also be applied to the progress of the work. That is, the evaluation unit 5 may calculate the sum of TS1 and TS2, which are values at the completion stage up to work B described in FIG. 3A as the above-mentioned standard work time (not the stage at which the entire work is completed, but the stage at which the work is in progress, for example, the stage at which both work A and work B are completed), and compare this value with the actual work time at the completion stage up to work B. In this case, the threshold value may be set to the actual work time corresponding to σ _B =-1 based on the distribution of the actual work time at the completion stage up to work B and the standard deviation (here, σ _B ) obtained from this distribution.

Next, in step ST4, a warning, i.e., a work delay notice is displayed on the information input/output/display 1 such as the mobile device of the work supervisor, to notify the work supervisor that wasted time is occurring. Note that this work delay notice can be sent when the entire work is completed, or even before the entire work is completed, if the actual work time equivalent to the above-mentioned σ _B = -1 is exceeded, a warning (work delay notice) can be displayed on the information input/output/display 1 to notify the work supervisor that wasted time is occurring.

In addition, in step ST5, if the actual work time is equal to or less than the threshold value of the standard work time, the standard work time is reset based on the actual work time previously acquired and the actual work time currently acquired.

Next, the flow chart shown in FIG. 7 will be described below in the order of operations.
First, in step ST6, the actual working time of a skilled worker is acquired in the skilled worker's working time 73 of the individual actual working time recording unit 7, which records the actual working time for each worker, by operating the information input/output and display unit 1 (inputting the start of work or the end of work, etc.). If the worker is a skilled worker, the information input/output and display unit 1b is used, if the worker is neither skilled nor unskilled (ordinary worker), the information input/output and display unit 1c is used, and if the worker is unskilled, the information input/output and display unit 1d is used. In addition, if the person in charge of work is responsible, the information input/output and display unit 1a is used (see FIG. 1).

Next, in step ST7, the actual work time of the unskilled worker is obtained in the unskilled worker work time 71 in the individual actual work time recording unit 7 by operating the information input/output/display unit 1 (such as inputting the start of work or the end of work).

Next, in step ST8, the actual work time of the skilled worker and the actual work time of the unskilled worker are displayed by operating the information input/output display 1 (such as inputting the start of work or the end of work), and the difference between these values is calculated.

Next, in step ST9, the difference between the actual work time of the skilled worker and the actual work time of the unskilled worker is compared with a predetermined value, and if this difference is greater than the predetermined value, the process proceeds to step ST9, which will be described below. If the difference in the actual work time is equal to or less than the predetermined value, the process returns to the operation described above as step ST5.

Here, the predetermined difference in actual work time can be, for example, the difference when the actual work time of an unskilled worker is twice the actual work time of an experienced worker, that is, the value at which the difference becomes the actual work time of an experienced worker.

Finally, in step ST10, the next operation is executed when the difference between the actual work time of the skilled worker and the actual work time of the unskilled worker is large. The operation is to analyze the work time of the unskilled worker and find elements (waste) that can reduce the work time, thereby correcting the work time.

Next, using the flowchart shown in Figure 8 and the block diagram showing the configuration of the real-time work time management equipment 100a shown in Figure 9, we will specifically explain a method for analyzing the work time of unskilled workers and improving wasted work time.

First, in step ST11, the actual work time of a skilled worker is compared with the actual work time of an unskilled worker, and an unskilled worker is identified if the difference in actual work time is greater than a predetermined value.

Next, in step ST12, for the identified unskilled worker, the actual work times 61 to 65 for each of the five types of work (work A to work E) are obtained using the data in the work-specific actual work time recording unit 6.

Next, in step ST13, the standard operation time calculation unit 4 is used to calculate all of the operation time differences ΔT1 to ΔT5 between the actual operation times 61 to 65 for each of the five types of operations confirmed above and the standard operation times TS1 to TS5 calculated for each operation.

Next, in step ST14, the values of the work time differences ΔT1 to ΔT5 calculated in step ST13 above are compared to find work content whose value is greater than the pre-given work time difference ΔTg, and the work manager is notified of the work content and its corresponding work time difference value via the information input/output/display 1a of the work manager. The following describes the operation of this real-time work time management equipment when only ΔT1 is greater than ΔTg.

Next, in step ST15, the work manager selects and displays training video data for work A from the video database provided in the information processing device 2a of the real-time work time management equipment 100a on the information input/output/display device 1d held by the identified unskilled worker as shown in Figure 9, and instructs the unskilled worker to perform the entire work again while watching the video data.
Finally, in step ST16, the identified unskilled worker uses the information processing device 2 to import the corresponding video data into his/her own information input/output/display 1d (unskilled worker's information input/output/display 1d), and performs task A while watching this video data, and then performs tasks B to E in order.

The relevant video data is, for example, a video of task A performed by an expert, and by performing task A while watching this, the identified unskilled person is expected to complete task A in the same amount of time as if the expert had performed it. In this case, ΔT1<ΔTg is naturally satisfied. In other words, since it can be said that the information processing device also has a function for training unskilled people, it can be seen that the information processing device can be used for teaching or training unskilled people by further providing video data of the work content for each task performed by an expert.
In particular, when the work in question is non-routine work such as regular inspections of nuclear power plants or thermal power plants, the majority of workers are likely to be inexperienced, and since inexperienced workers have few opportunities to actually experience the work, this is useful for training when not engaged in actual work.

As described above, according to the real-time work time management equipment 100 of the first embodiment, by using the information processing device 2 to utilize the actual work time obtained from past data, the wasted time during the work currently being performed can be reported to the work manager, thereby making it possible to manage the wasted time occurring during work in real time, regardless of whether the person performing the work is an expert or an unskilled person.
In addition, because the system can automatically compare actual work time obtained from past data with current work time and report the result, there is no need for a person to measure to detect whether or not there is waste in the work. This reduces the labor required to determine whether or not there is wasted time during work, regardless of whether the person performing the work is an expert or an unskilled person.
