Abstract

A storage unit (150) stores work schedule information (151) for which a work schedule of a worker has been set. A fatigue level calculation unit (110) calculates a movement fatigue level which arises from the movement state in which the worker moves to a work site, and a work fatigue level which arises from the content of the work performed by the worker, and calculates the sum of the movement fatigue level and the work fatigue level as a total fatigue level. A safety assessment unit (120) determines whether or not the total fatigue level exceeds a limit fatigue level. If the total fatigue level exceeds the limit fatigue level, then a load adjustment unit (130) adjusts the movement conditions or the work content such that the total fatigue level decreases to a level equal to or less than the limit fatigue level.

***Description of operation***
The work planning process S100 of the work planning apparatus 100 according to the present embodiment will be described with reference to FIG.

<Fatigue degree calculation processing: step S101 and step S102>
In the fatigue level calculation process, the fatigue level calculation unit 110 is based on the work schedule information 151 and is caused by the movement fatigue level T caused by the movement situation when the worker moves to the work site and the work content of the worker. The work fatigue level W is calculated. Then, the fatigue degree calculation unit 110 calculates the sum of the movement fatigue degree T and the work fatigue degree W as the total fatigue degree M. The movement status is represented by the movement distance 512, the equipment to be carried when moving, and the method of carrying the equipment.

In step S 101, the fatigue degree calculation unit 110 reads the work schedule information 151 from the storage unit 150. In the work schedule information 151, a series of works is preset as a work schedule for one worker on the day. When there are a plurality of work schedule information 151, the fatigue degree calculation unit 110 reads one work schedule information 151 from the storage unit 150.

In step S102, the fatigue degree calculation unit 110 calculates the total fatigue degree M which is the sum of the work fatigue degree W and the movement fatigue degree T of the worker for the work schedule information 151.
The fatigue level calculation unit 110 calculates the work fatigue level W by taking the sum of the values of the work fatigue levels determined for each work content 515. In the example of FIG. 2, the work fatigue degree of the work A is W1, the work fatigue degree of the work B is W2, and the work fatigue degree of the work C is W3. Therefore, the work fatigue level W=W1+W2+W3. When the fatigue level calculator 110 calculates the work fatigue level W, a coefficient determined by the physical condition of the worker on the day may be used. For example, a coefficient determined by the physical condition of the worker of the day is set in the today's fatigue level 533 column of the limit fatigue level information 153. The fatigue level calculation unit 110 calculates the final value of the work fatigue level W by multiplying the work fatigue level W by the coefficient in the today's fatigue level 533 column of the limit fatigue level information 153.

Further, the fatigue degree calculation unit 110 calculates the movement fatigue degree T based on the moving distance 512, the moving means 513, and the equipment 517 used. Specifically, the fatigue degree calculation unit 110 calculates the product of the movement distance 512, the movement means coefficient 514, the equipment weight coefficient 522, and the possession method coefficient 523 by using the coefficient information 152 to calculate the movement fatigue degree T. calculate.

First, the fatigue degree calculation unit 110 moves, for each equipment, the product of the movement distance 512, the movement means coefficient 514, the equipment weight coefficient 522, and the possession method coefficient 523 from the work schedule information 151 and the coefficient information 152 for each equipment. Calculated as fatigue level. Then, the fatigue degree calculating unit 110 calculates the movement fatigue degree T by adding all the movement fatigue degrees for each equipment.
Regarding the work schedule information 151 in FIG. 2, when the moving fatigue degree T is calculated using the coefficient information 152 in FIG.
Movement fatigue degree T=L1×T_car×(Ma×Ba_car+Mb×Bb_car)+L2×T_car×(Mc×Bc_car+Mb×Bb_car)

For example, when the worker carries the equipment a to the site 1 on foot with public transportation, the worker may walk from the work station to the nearest station of the work site, or from the nearest station of the site 1 to the site 1 of the work site. It is preferable to calculate separately from the nearest station to the nearest station of the site 1 as public transportation.

Then, the fatigue degree calculation unit 110 calculates the total fatigue degree M=work fatigue degree W+movement fatigue degree T as the total fatigue degree M.

<Safety Evaluation Processing: Step S103 and Step S104>
In the safety evaluation process, the safety evaluation unit 120 compares the limit fatigue level indicating the limit value of the fatigue level of the worker with the total fatigue level, and determines whether the total fatigue level exceeds the limit fatigue level. To do. The safety evaluation unit 120 uses the limit fatigue level information 153 to determine whether the total fatigue level exceeds the limit fatigue level.

In step S103, the safety evaluation unit 120 acquires the limit fatigue level LM of the worker from the limit fatigue level information 153. Then, the safety evaluation section 120 compares the total fatigue level M with the limit fatigue level LM.
If the total fatigue level M exceeds the limit fatigue level LM in step S104, the safety evaluation unit 120 turns on the adjustment necessity flag of the work schedule information 151, and proceeds to step S105. In step S104, when the total fatigue level M does not exceed the limit fatigue level LM, the safety evaluation section 120 turns off the adjustment necessity flag 519 of the work schedule information 151 or does nothing, and proceeds to step S107. ..

<Load adjustment processing: step S105 and step S106>
In the load adjusting process, the load adjusting unit 130 adjusts the movement status or the work content so that the total fatigue degree M does not exceed the limit fatigue degree LM when the total fatigue degree M exceeds the limit fatigue degree LM. .. The load adjusting unit 130 recalculates the total fatigue level M for the work schedule information 151 after adjusting the movement status or the work content. Then, the load adjusting unit 130 turns off the adjustment necessity flag 519 when the total fatigue degree M after the recalculation does not exceed the limit fatigue degree LM.

In step S105, the load adjusting unit 130 determines whether the moving means or the work content can be adjusted. If the means of transportation or the work content can be adjusted, the process proceeds to step S106. If it is impossible to adjust the moving means or the work content, the process proceeds to step S107.
In step S106, the load adjusting unit 130 adjusts the moving unit 513 or the work content 515. Here, the load adjusting unit 130 adjusts the moving means in the moving situation. Adjustment of the moving means 513 or the work content 515 will be described with reference to FIG.
In step S107, the load adjustment unit 130 determines whether the processing has been completed for all work schedule information 151. When the processing is completed for all work schedule information 151, the process proceeds to step S108. If there is unprocessed work schedule information 151, the load adjusting unit 130 returns to step S101 and processes the next work schedule information 151.

The operation of the load adjustment process according to the present embodiment will be described with reference to FIG.
In step S201, the load adjusting unit 130 adjusts the moving means and determines whether the adjusting of the moving means is completed. Specifically, the load adjusting unit 130 determines whether there is a service vehicle available in the work base. If there is a service vehicle that can be used, the load adjusting unit 130 secures the service vehicle as a transportation means, and proceeds to step S203. Specifically, the load adjustment unit 130 refers to the vehicle usage status 154 stored in the storage unit 150, and confirms the presence or absence of a service vehicle. In the vehicle usage status 154, available service vehicles and usage status of the service vehicles are set for each work site. If no service vehicle is available, the process proceeds to step S202.

In step S202, the load adjusting unit 130 adjusts the work content and determines whether the work content adjustment is completed. Specifically, the load adjusting unit 130 extracts, from the work schedule information 151, work contents for which a check is not set for the support necessity 518 of the day. Then, the load adjusting unit 130 resets the work content for which the check is not set for the support necessity 518 of the current day after the next day. When the work resetting is completed, the process proceeds to step S203. If the work cannot be reset, the process proceeds to step S107.

In step S203, the load adjusting unit 130 recalculates the total fatigue level of the work schedule information 151. That is, when the service vehicle can be secured in step S201, or when the work resetting is completed, the load adjusting unit 130 recalculates the total fatigue level in the work schedule information 151.
In step S204, when the total fatigue level M exceeds the limit fatigue level LM, the load adjusting unit 130 keeps the adjustment necessity flag 519 of the work schedule information 151 on, and proceeds to step S107. When the total fatigue level M does not exceed the limit fatigue level LM, the load adjusting unit 130 proceeds to step S205.
In step S204, the load adjusting unit 130 turns off the adjustment necessity flag 519 of the work schedule information 151, and proceeds to step S107.

Next, returning to FIG. 5, the description will be continued.
In step S108, the load adjustment unit 130 adjusts the entire work schedule information 151. The load adjustment unit 130 extracts from the storage unit 150 the work schedule information 151 with the adjustment necessity flag 519 turned on. With respect to the work schedule information 151 with the adjustment necessity flag 519 being on, the load adjusting unit 130 allocates some of the works included in the work content to another worker having a sufficient degree of fatigue. That is, if there is a worker whose total fatigue level exceeds the limit fatigue level even if a service vehicle is secured or unnecessary work is reset, some of the work included in the work content of the day is Assign to other workers who can afford fatigue. When the total fatigue level of some workers exceeds the limit fatigue level, the load adjusting unit 130 allocates the work so that the variation of the work loads of all the workers belonging to the work base becomes small.

Here, an example of the load adjusting process by the load adjusting unit 130 will be described.
(1) The load adjusting unit 130 calculates, for each worker who belongs to the work base, the total fatigue level of a plurality of transportation means such as a service vehicle or public transportation. Here, the load adjusting unit 130 selects a moving means that minimizes the total fatigue level of each worker. When the number of service vehicles in the work base becomes smaller than the number of workers who have selected the service vehicle, the load adjusting unit 130 allocates the service vehicles in order from the worker having the largest total fatigue level when the service vehicle is not selected. ..
(2) According to the above procedure, there are cases where the total fatigue level exceeds the limit fatigue level, but some workers cannot use the service vehicle. In this case, the load adjusting unit 130 adjusts the work content of the worker. When adjusting the work content, the failure risk of the target device in the work to be performed on the day may be used. The failure risk is calculated from the failure occurrence probability of the device and the degree of influence when the device fails. The device failure occurrence probability is calculated using the device health condition determined from the data acquired by the sensor attached to the device or the past failure history. The degree of influence when the device fails is calculated from data such as the degree of prevalence of the influence when the device fails. The load adjustment unit 130 may use the failure risk to determine whether or not the work needs to be handled on the day. That is, a threshold value is provided for determination.
By using this failure risk, a check may be set in the field of the necessity/non-necessity 518 of the day of the work schedule information 151. The load adjusting unit 130 resets the work that does not need to be handled on the day after the next day.
(3) If the total fatigue level exceeds the limit fatigue level even after performing the above procedure, the load adjusting unit 130 performs some of the work included in the work content of the current day and other work with a sufficient fatigue level. Assign to staff.
(4) When some workers have a total fatigue level exceeding the limit fatigue level, the load adjusting unit 130 allocates the work so that the variation in the work load of all the workers belonging to the work site is reduced.

In the present embodiment, the load adjusting unit 130 adjusts the moving means as the adjustment of the moving situation. However, the equipment or the method of carrying the equipment may be adjusted to adjust the movement status.

<Work addition processing: step S109 and step S110>
When the total fatigue level does not exceed the limit fatigue level, the work adding section 140 adds new work to the work schedule information 151 within a range in which the total fatigue level does not exceed the limit fatigue level.

In step S109, the work adding unit 140 determines whether or not there is work schedule information 151 with a margin of fatigue. If there is work schedule information 151 with a margin of fatigue, in step S110, the work addition unit 140 adds a work to the work content of the day within a range in which the total fatigue does not exceed the limit fatigue.

When the safety evaluation unit 120 determines that the total fatigue level is smaller than the limit fatigue level, the work addition unit 140 is a work scheduled to be performed on and after the next day within a range in which the total fatigue level does not exceed the limit fatigue level. Add from the contents to the work contents of the day.
At this time, the work adding unit 140 uses the failure risk of the device to give priority to the work targeting the device. The device failure risk is calculated using the device failure occurrence probability and the degree of influence when the device fails. The work addition unit 140 adds to the work content of the day in order from the work item with the highest priority, in the range in which the total fatigue level does not exceed the limit fatigue level.

A specific example of the work addition process according to the present embodiment will be described with reference to FIG. 7.
When the total fatigue level of the works A, B, and C on the day is 16, while the limit fatigue level of the worker is 20, there is a margin of 4 in the fatigue level. At this time, with respect to the works D, E, and F scheduled to be performed on and after the next day, the failure probability of the device is multiplied by the influence degree to calculate the device failure risk. Then, work D, work E, and work F are in order from the highest priority. Since the fatigue allowance is 4, the work D and the work E are added. Further, after the work is given a priority, it may be added only to the work in which the risk of failure of the device exceeds a threshold value (referred to as a corresponding threshold value). As described above, by limiting the work to be added by the required threshold, it is possible to prevent the work from being added when the risk of failure of all devices is low.

In step S111, the schedule transmission unit 160 transmits the work schedule information 151 to the worker terminal. When the load adjusting unit 130 cannot adjust the schedule, the schedule transmitting unit 160 may add information indicating the fact to the work schedule information 151 and transmit the work schedule information 151 to the worker terminal.
