[First Embodiment]
Hereinafter, a risk calculation system 100 according to a first embodiment of the present invention will be described with reference to the drawings.
The risk level calculation system 100 according to the present embodiment produces a product including a plurality of work areas in which a plurality of workers work when manufacturing one product such as a ship, an aircraft, and other large machine products. Built as part of the management system. In these products, when one product is produced, each of a plurality of workers sequentially performs a plurality of operations in a plurality of work areas. At that time, a new work is assigned to each worker when one work is completed. The completed work and the new work have different work contents and work environments (work requirements). Further, when work in a certain work area is completed, a new work may be performed in another work area.

In the risk calculation system 100 of the present embodiment, an administrator who manages a production system in which work requirements assigned to each worker are sequentially updated, and work areas in which each worker performs work is also sequentially updated can be obtained by a manager. This is a system that makes it possible to focus on a high-risk area when the area is monitored.
Hereinafter, each part of the risk calculation system 100 of the present embodiment will be described.

  As shown in FIG. 1, the risk calculation system 100 according to the present embodiment includes a control unit 10 (determination means), a storage unit 20, a display unit 30, and an input unit 40. The storage unit 20 includes a work management table 21 (work management means) and an area management table 22 (area management means). The control unit 10 includes a first calculation unit 11 and a second calculation unit 12.

First, the work management table 21 provided in the storage unit 20 will be described.
The work management table 21 is a table that manages a plurality of workers who work when producing a product and work requirements of work assigned to each of the plurality of workers in association with each other. As illustrated in FIG. 2, the work management table 21 manages a plurality of workers A to E in association with work requirements including a plurality of items assigned to each worker. Further, in order to calculate a work risk level to be described later, a reference value is assigned as a numerical value to each of the work requirements shown in FIG. Further, the portions indicated by circles (◯) in FIG. 2 indicate work requirements assigned to each worker.

As shown in FIG. 2, work requirements are classified into work contents, work personnel, work objects, work environments, and work patterns as types of work requirements.
The work content that is one of the types of work requirements is further classified into a work type and a work posture. As work types, in the example shown in FIG. 2, carbon gas welding, TIG welding, and others are illustrated as examples of performing welding work. Each of the workers A to E is assigned one of carbon gas welding, TIG welding, and others, and is indicated by a circle in FIG. The reference value for high-risk carbon gas welding is 3, and the reference value for TIG welding is 1. Other reference values are zero. The working posture is classified as an upward posture or a downward posture. The reference value for the high-risk upward posture is 1, and the reference value for the downward posture is 0.

  Workers who are one of the types of work requirements are further classified into necessary qualifications and years of experience. Necessary qualifications are classified into cases where in-house verification is required and cases where external verification is required. Since the conditions required for the external verification are stricter than the internal verification, the reference value when the internal verification is required is 1 with a high degree of risk, and the reference value when the external verification is required is 0. As the number of years of experience, the risk level tends to decrease as the number of years of experience increases, so the standard value of the risk level of 1 year or less is 3, the standard value of 2-5 years is 2, and 6 The reference value for -9 years is 1, and the reference value for 10 years or more is 0.

  Work objects that are one of the types of work requirements are classified according to the object weight. Since the danger tends to increase as the weight of the object to be worked increases, the reference value when the target weight is 21 kg or more is 2, the reference value is 1 when the object weight is 6 to 20 kg, and 5 kg or less. In this case, the reference value is 0.

  The work environment which is one of the types of work requirements is further classified into a work space and a ventilation state. The work space is classified into a closed space and an open space. The closed space is highly dangerous because it is separated from other spaces. For this reason, the reference value of the risk level of the closed space is 1, and the reference value of the risk level of the open space is 0. The ventilation state is classified as poor and good. When the ventilation state is poor, the risk level is high, so the reference value is 1. When the ventilation state is good, the risk level is 0.

  Work styles that are one of the types of work requirements are further classified into working hours and work contracts. The working hours are classified into night work and day work. The standard value for the risk of night work is as high as 3, and the standard value for the risk of work during the day is low as 0. Service contracts are classified into dispatch contracts, contract contracts, and regular employees. Since regular employees have a high level of proficiency in their work, the risk standard value is low, 0, the contract contract standard value is 2, and the dispatch contract standard value is 3, which increases.

  The work requirements of the work management table 21 shown in FIG. 2 and the setting of the reference value of each work requirement are input via the input unit 40 by the administrator. The control unit 10 controls the display unit 30 to display a setting screen and accept settings from the input unit 40 when setting work requirements and reference values for each work requirement. The control unit 10 controls the storage unit 20 to reflect the setting received from the input unit 40 in the work management table 21.

  In addition, assignment of work requirements to the workers A to E in the work management table 21 shown in FIG. 2 is also input by the administrator via the input unit 40. When assigning work requirements, the control unit 10 controls the display unit 30 to display an input screen and accept input from the input unit 40. The control unit 10 controls the storage unit 20 to reflect the work requirement assignment received from the input unit 40 in the work management table 21. The work requirement is assigned to the worker when the work of each worker is completed.

  The work management table 21 shown in FIG. 2 shows a state before the worker D finishes the work, and the work management table 21 shown in FIG. 3 shows a state after the worker D finishes the work. As is clear from a comparison between FIG. 2 and FIG. 3, the work type of the worker D is changed from “others” to “carbon gas welding”. In addition, the work posture of the worker D is changed from “downward” to “upward”. In addition, the work target of the worker D is changed from “6 to 20 kg” to “21 kg or more”. Further, the ventilation state of the work environment of the worker D is changed from “good” to “bad”.

Next, the area management table 22 provided in the storage unit 20 will be described.
The area management table 22 is a table for managing a work area and a worker performing in the work area in association with each other for each of a plurality of work areas in which a plurality of workers perform work. As shown in FIG. 4, workers A to E are assigned to the three work areas X, Y, and Z. Circles (◯) shown in FIG. 4 indicate workers assigned to each work area.

  The area management table 22 shown in FIG. 4A shows a state before the worker D finishes the work, and the area management table 22 shown in FIG. 4B shows the state after the worker D finishes the work. Show. As apparent from the comparison between FIG. 4A and FIG. 4B, the work area of the worker D is changed from “work area Y” to “work area Z”.

  Next, calculation processing executed by the first calculation unit 11 and the second calculation unit 12 of the control unit 10 will be described. Here, the control part 10 implement | achieves the process which the 1st calculation part 11 and the 2nd calculation part 12 perform by running the control program memorize | stored in ROM etc. FIG. For example, the first calculation unit 11 and the second calculation unit 12 are incorporated in the control unit 10 as application program modules included in the control program.

  The first calculator 11 calculates the risk level of the work performed by each worker A to E based on the work requirements managed by the work management table 21. In the case of the work management table 21 shown in FIG. 2, the first calculation unit 11 adds the reference values corresponding to the work requirements of each worker, and calculates the total value as the risk level. For example, in the case of the worker A, the reference value 1 (reference value corresponding to “carbon gas welding”), the reference value 1 (reference value corresponding to “in-house certification”), and the reference value 2 (“year of experience”) Corresponding reference value) and reference value 2 (reference value corresponding to “21 Kg or more”) are added to calculate the risk of worker A as 6. Similarly, the first calculation unit 11 sets the danger level of the worker B to 9, the danger level of the worker C, 16, the danger level of the worker D, and the danger level of the worker E to 5, respectively. calculate.

  Further, in the case of the work management table 21 shown in FIG. 3, the first calculation unit 11 sets the danger level of the worker A to 6, the danger level of the worker B, 9 and the danger level of the worker C to 16. The risk level of the worker D is calculated as 15, and the risk level of the worker E is calculated as 5, respectively. In the work management table 21 shown in FIG. 3, since the work requirement of the worker D is newly assigned, the danger level of the worker D is changed from 9 to 15.

  The second calculation unit 12 determines each work based on the work risk level of each worker calculated by the first calculation unit 11 and the work area managed by the area management table 22 when each worker performs work. Calculate the area risk of the area. Specifically, the second calculation unit 12 calculates, for each work area, a value obtained by summing the danger levels of the workers assigned to the work area as the area risk level of the work area.

  As shown in FIG. 4A, before the worker D finishes the work, the worker A (risk level 6) and the worker B (risk level 9) are assigned to the work area X. Therefore, the second calculation unit 12 calculates the area risk level of the work area X as 15. Similarly, since the worker C (risk level 16) and the worker D (risk level 9) are assigned to the work area Y, the second calculation unit 12 calculates the area risk level of the work area Y as 25. . Similarly, since the worker E (hazard level 5) is assigned to the work area Z, the second calculation unit 12 calculates the area risk level of the work area Z as 5.

  As shown in FIG. 4B, after the worker D finishes the work, the worker A (risk level 6) and the worker B (risk level 9) are assigned to the work area X. Therefore, the second calculation unit 12 calculates the area risk level of the work area X as 15. Similarly, since the worker C (hazard level 16) is assigned to the work area Y, the second calculation unit 12 calculates the area risk level of the work area Y as 16. Similarly, since the worker D (risk level 15) and the worker E (risk level 5) are assigned to the work area Z, the second calculation unit 12 calculates the area risk level of the work area Z as 20. .

FIG. 5 is a diagram showing an example of the display screen of the display unit 30 shown in FIG. FIG. 5A shows the area risk level before the worker D finishes the work. FIG.5 (b) shows the area | region risk after the operator D complete | finishes work.
As described above, before the worker D finishes the work, the area risk of the work area X is 15, the area risk of the work area Y is 25, and the area risk of the work area Y is 5. It has become. Therefore, before the worker D finishes the work, the area risk of the work area Y is the highest among the three work areas. On the other hand, after the worker D finishes the work, the area risk of the work area X is 15, the area risk of the work area Y is 16, and the area risk of the work area Y is 20. . Therefore, after the worker D finishes the work, the area risk of the work area Z is the highest of the three work areas.

  In the example of the display screen shown in FIG. 5, the work area with the highest area risk is colored or marked so that the work area with the highest area risk can be distinguished from other work areas. In this way, the administrator assigns a new work requirement and work area to the worker D, and changes the area risk of the work area Y and the work area Z to the highest area risk. It is possible to appropriately identify the work area for which is calculated.

  6 is a diagram showing a modification of the display screen of the display unit shown in FIG. FIG. 6A shows a display screen of the display unit 30 before the worker D finishes the work. On the other hand, FIG.6 (b) shows the display screen of the display part 30 after the operator D complete | finishes work. In FIG. 6, reference numeral 601 corresponds to the work area X, reference numeral 602 corresponds to the work area Y, and reference numeral 603 corresponds to the work area Z. FIG. 6 shows a product such as a ship that is divided into a plurality of layers. In FIG. 6, each of the three hierarchies corresponds to three work areas, and the work area with the highest area risk among the three work areas is distinguished from other work areas so that it can be distinguished from other work areas. Are displayed in different colors. By displaying each level three-dimensionally on the display screen of the display unit 30, the administrator can intuitively recognize the risk level of each work area.

Next, the risk level calculation method executed by the control unit 10 of the present embodiment will be described with reference to the flowchart of FIG. The control unit 10 executes each process shown in FIG. 7 by executing a control program stored in a ROM or the like.
In step S701 (first calculation step), the first calculation unit 11 of the control unit 10 reads the work management table 21 illustrated in FIG. 2 from the storage unit 20, and calculates the work risk levels of the workers A to E, respectively.

In step S702 (second calculation step), the second calculation unit 12 of the control unit 10 calculates the work risk level of the workers A to E in step S701 and the area management table 22 shown in FIG. Based on the above, the area risk of each work area is calculated.
In step S703, the control unit 10 displays the display shown in FIG. 5A or FIG. 6A based on the work risk calculated by the first calculation unit 11 and the area risk calculated by the second calculation unit 12. The display unit 30 is controlled to display the screen.

  In step S704, the control unit 10 determines whether the work assigned to one of the workers via the input unit 40 has ended and a new work has been input. If YES, the process proceeds to step S705. If not, step S704 is executed again. When one of the workers A to E finishes the work defined by the work requirements, the administrator inputs via the input unit 40 that the work is finished.

In step S705, the control unit 10 determines whether or not new work requirements and work areas have been input for the worker determined to have finished work in step S704. If YES, the process proceeds to step S706. If not, step S705 is executed again.
In step S705, the control unit 10 inputs to the display unit 30 in order to assign a new work and its work requirements to the worker who has finished the work (for example, the worker D) and a work area in which the new work is to be performed. Display the screen. The administrator performs input via the input unit 40 after this input screen is displayed.

In step S <b> 706, the control unit 10 updates the work management table 21 based on the work requirements for new work input via the input unit 40.
In step S <b> 707, the control unit 10 updates the area management table 22 based on the work area for performing a new work input via the input unit 40.
After step S707, the process shown in FIG. 7 is temporarily ended, and the process from step S701 is started again.

When the work of the worker D is completed, the work requirement shown in FIG. 3 is input as a new work and work requirement, and the work area Z is assigned as a new work area, the work management table 21 is as shown in FIG. To those shown in FIG. Similarly, the area management table 22 is updated from that shown in FIG. 4A to that shown in FIG.
And the display screen displayed on the display part 30 is updated by performing step S701-step S703 based on the updated work management table 21 and the area | region management table 22. FIG. For example, the display screen shown in FIG. 5 (a) or 6 (a) is updated to the display screen shown in FIG. 5 (b) or FIG. 6 (b) in response to the completion of the work of the worker D. The

Next, the operation and effect of the risk calculation system of the present embodiment described above will be described.
The risk level calculation system 100 according to the present embodiment includes a work management table 21 that manages workers A to E in association with work requirements assigned to each of the workers A to E, and workers A to E. For each of the work areas X, Y, and Z in which E performs work, an area management table 22 that manages the work area and a worker who performs work in the work area in association with each other is provided. Further, the risk level calculation system 100 includes a first calculation unit 11 that calculates the work risk level of the work performed by each worker based on the work requirements managed by the work management table 21, and each work by the area management table 22. A second calculation unit that calculates an area risk of each work area based on the worker managed in association with the area and the worker's work risk calculated by the first calculation unit; .

According to the risk calculation system 100 of the present embodiment, the risk of work performed by each worker is calculated based on the work requirements assigned to each of the workers A to E, and the calculated work of each worker is calculated. Based on the risk level and the work area managed by the area management table when each worker performs work, the area risk level of each work area is calculated.
In this way, it is possible to provide a risk calculation system 100 that can appropriately grasp which work area is dangerous according to the risk of the work requirement assigned to the worker. Can do.

In the risk calculation system 100 of the present embodiment, the control unit 10 determines whether or not the worker has finished the work assigned to the worker, and determines that the work has been finished. The table assigns a new work to the worker who has finished the work and updates the work requirements, and the area management table assigns the worker who has finished the work to one of the work areas A to E.

In this way, an administrator who manages a plurality of work areas can recognize a work area having the highest area risk level due to a difference in color from other work areas.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIGS.
The second embodiment is a modification of the first embodiment, and is the same as the first embodiment except for a case described below, and the description below is omitted.
In the second embodiment, when the first calculation unit 11 calculates the work risk level of each worker, the degree of similarity with the past disaster cases is taken into account, and the work is performed so that the value increases when the degree of similarity is high. The risk level is calculated. This will be specifically described below.

  Unlike the storage unit 20 of the risk calculation system 100 of the first embodiment described above, the storage unit 20 of the risk calculation system 200 of the present embodiment further includes a case management table 23. An example of the case management table 23 is shown in FIG. A case management table 23 shown in FIG. 9 is a table for managing work requirements corresponding to past disaster cases.

  As shown in FIG. 9, the case management table 23 is a table that stores work requirements in past disaster cases 1 to 3. The work requirements marked with a circle (◯) in FIG. 9 indicate the work requirements for the work performed in the disaster case. Therefore, it is considered that the work having a high similarity to the disaster cases 1 to 3 stored in the case management table 23 is a work having a relatively high possibility of reaching a disaster.

  Therefore, the first calculation unit 11 of the present embodiment refers to the case management table 23 when calculating the work risk levels of the workers A to E. Specifically, the first calculation unit 11 compares the work requirements of each worker illustrated in FIG. 2 with the disaster cases 1 to 3 stored in the case management table 23, and the past disaster cases 1 to 3 are compared. When the similarity is high, a predetermined value is further added to the work risk calculated as the sum of the reference values of the work requirements of each worker.

  When the degree of similarity is high, for example, the type of work, work posture, required qualification, years of experience, target weight, work space, ventilation status, working hours, work contract, shown as “Contents of work requirements” in FIG. The case where 8 or more items out of 9 items are in agreement. However, the condition of 8 items or more can be switched to a condition of 9 items or more or 7 items or more.

  In this embodiment, the 1st calculation part 11 shall judge that a similarity degree is high, when eight or more items of work requirements correspond. When the work requirements of the cases 1 to 3 in the case management table are compared with the work requirements of the workers A to E, and the number of items with the same work requirements (similarity in the present embodiment) is calculated, Become. In the present embodiment, the first calculation unit 11 determines that the similarity is high when the similarity is 8 or more. Therefore, the similarity of the work requirement of the worker A with respect to the case 1 is 8, so the similarity is Judged to be high. Similarly, the similarity of the work requirement of the worker B to the case 21 is 8, so that the similarity is determined to be high.

  The first calculation unit 11 of this embodiment further adds 6 (predetermined value) to the total value of the reference values calculated in the first embodiment as the work risk level of the worker who is determined to have high similarity. It shall be added. Although an example of the predetermined value is “6” here, other numerical values may be set. In the example shown in FIG. 5A, the risk level of the worker A is calculated as 6, and the risk level of the worker B is calculated as 9. In this embodiment, since 6 is added to each, the first calculation unit 11 calculates the danger level of the worker A as 12 and the danger level of the worker B as 15. In this case, the risk level of the work area X is 27 which is 12 plus 12 and is calculated to be higher than the work area Y.

As described above, the risk level calculation system 200 according to this embodiment includes the case management table 23 that manages work requirements corresponding to past disaster cases. Then, the first calculation unit 11 sets a predetermined value when the similarity between the work requirement assigned to any worker managed by the work management table 21 and the work requirement managed by the case management table 23 is high. The work risk level of the worker is calculated by addition.
In this way, when the work requirement assigned to one of the workers is highly similar to the work requirement corresponding to the past disaster case, the risk level of the work requirement is calculated to be high and appropriately It can be reflected as the danger level of the work area.

Other Embodiment
In the embodiment described above, the risk calculation system 100 includes a plurality of work areas in which a plurality of workers work when manufacturing one product such as a ship, an aircraft, and other large machine products. Although it was incorporated as a part of the product production management system, other modes may be used. For example, it may be incorporated as part of a production management system in a factory having a plurality of work areas.

  In the embodiment described above, various modifications can be made to the types of work requirements and the contents of work requirements shown in the work management table. For example, it is possible to apply not only welding work classification but also various work such as assembly work classification and transport work classification as work types. In addition, gender is added as a work requirement for the worker, and the work table may be such that the reference value for calculating the risk level for men is low and the reference value for calculating the risk level for women is high.

  In the above-described embodiment, the work management table 21 and the area management table 22 indicate the latest work requirement assignment and work area assignment at the current time, respectively, but may be in other forms. For example, work requirements and work area assignments at each future time may be stored in time series based on a production plan or the like. In this case, the 1st calculation part 11 and the 2nd calculation part 12 read the work management table 21 and the area | region management table 22 corresponding to the future time input from the administrator via the input part 40, respectively, and each work risk degree And the area risk is calculated.

  In this way, the administrator can identify the risk level of each work area at the future time by designating the future time. For example, when the administrator plans to go around the work area after 5 hours, the administrator can display the risk level of each work area after 5 hours on the display screen of the display unit 30 via the input unit 40. . Therefore, the administrator can plan in advance which work area should be visited in a case where the work area is visited after 5 hours.

  In the example of the display screen shown in FIG. 6 of the above-described embodiment, a work area consisting of a plurality of hierarchies is handled as one work area for each hierarchy, but other modes may be used. For example, each hierarchy may be divided into a plurality of areas, and each of the divided areas may be handled as a work area.
