Description

Technical Field

[0001] Embodiments of the present invention relate to a work process planning system based on weather prediction data and a work process planning method based on weather prediction data.

Background Art

[0002] In construction work of facilities such as nuclear power plants, all weather conditions have a great impact on on-site work. For example, wind, snow, or rain may impede work safety. In some cases, sea transportation may be impossible due to wave height. Also, commuting may be restricted due to the risk of falling rocks on the commuting road. Furthermore, in summer, there is a possibility of heat stroke risk due to temperature and humidity. In addition, on the coast peculiar to nuclear power plants, rusting due to the amount of flying salt is a concern, so as a measure against salt damage, the temporary placement location of outdoor piping must be considered.

[0003] Currently, work managers formulate a process plan for on-site work while checking general weather forecasts and proceed with on-site work. When crane work or outdoor work cannot be carried out due to weather conditions, it becomes inevitable to review the work that is not affected by the weather, such as work in the workshop or indoor work.

[Figure 5] A flowchart illustrating the steps taken by the work process planning system using weather data, as shown in Figure 1. [Modes for carrying out the invention]

[0011] Hereinafter, embodiments for carrying out the present invention will be described based on the drawings. Figure 1 is a block diagram showing the configuration of a work process planning system using weather forecast data according to one embodiment. The work process planning system 10 using weather forecast data shown in Figure 1 predicts and determines whether or not on-site work can be carried out based on weather forecast data, obtains a predicted operating rate value, and modifies the pre-created work process based on the predicted operating rate value. It is composed of a weather forecast data acquisition unit 11, a process input unit 12, a determination calculation unit 13, a process modification unit 14, and a display unit 15.

[0012] The weather forecast data acquisition unit 11 acquires weather forecast data from a weather forecasting system (not shown) that predicts weather data such as rain, snow, wind, humidity, and temperature with high accuracy. This weather forecast data is, for example, forecast data for several weeks ahead, such as wind speed, rainfall, snowfall, wave height, temperature, humidity, weather warnings, and airborne salt content, and is displayed on the display unit 15.

[0013] The process input unit 12 inputs work processes that have been previously created in the process creation system 16.

[0014] The determination calculation unit 13 compares weather forecast data from the weather forecast data acquisition unit 11 with pre-set work non-performance conditions to determine whether, for example, on-site work can be performed several weeks in advance, and calculates, for example, a predicted operational rate for on-site work several weeks in advance. The aforementioned several weeks in advance is, in one example, two weeks in advance.

[0015] The above conditions for not performing work are days when the ground wind speed exceeds a specified value (e.g., 10 m / s), days when heavy rain exceeds a specified value (e.g., 50 mm), days when heavy snow exceeds a specified value (e.g., 25 cm), days when wave height exceeds a specified value (e.g., 1.5 m), days when the sea wind speed exceeds a specified value (e.g., 15 m / s), days when there is a high probability of weather warnings (heavy rain warnings, storm warnings, blizzard warnings, heavy snow warnings, high wave warnings, etc.), or days when the heat index (WBGT) is 25 degrees or higher (21 degrees or higher for those with a history of heatstroke) and there is a high risk of heatstroke. These conditions for not performing work reflect the following conditions stipulated for construction work of buildings, especially for the construction of nuclear power plants.

[0016] In other words, Article 522 of the Industrial Safety and Health Regulations states that, as a measure for "measures in case of inclement weather," "when working at a height of 2m or more, if there is a risk of danger to work due to strong winds, heavy rain, heavy snow, or lightning (including when a weather advisory or warning is issued and inclement weather is expected, with strong winds defined as an average wind speed of 10m / s per second or more over 10 minutes, heavy rain defined as a single rainfall of 50mm or more, and heavy snow defined as a single snowfall of 25cm or more), the primary contractor or general contractor shall decide to suspend work after consulting with the construction company." As another specific condition, if a construction vessel is anchored within the construction area and the wave and wind speed forecast values ​​within the construction area exceed 1.5m in wave height or 15m / s in wind speed within 48 hours, sea transport vessels will not be able to enter the port, and unloading work cannot be carried out. Furthermore, regarding risks during commuting, given the conditions of the access road to the nuclear power plant, if a weather warning (such as heavy rain, snow, or typhoon warning) is issued, there is a risk of commuting being impossible due to falling rocks or other incidents on the commute route, which could result in the worker being unable to commute. In addition, at work sites during the summer, measures to prevent heatstroke among workers stipulate that if the heat index (WBGT value) is 25 degrees Celsius or higher (21 degrees Celsius or higher for those with a history of heatstroke), and there is a high possibility of heatstroke occurring, the worker must wear a cooling vest or air-conditioned clothing.

[0017] The determination calculation unit 13 compares weather forecast data for several weeks (for example, two weeks) ahead with the conditions for not performing work. If the conditions for not performing work are met, it determines that, for example, on-site work for several weeks ahead is impossible. If the conditions for not performing work are not met, it determines that, for example, on-site work for several weeks ahead is possible. Based on this determination, the determination calculation unit 13 calculates, for example, a predicted utilization rate for on-site work several weeks ahead, on a weekly basis, using the number of actual working days excluding Saturdays, Sundays, and public holidays as the denominator and the number of days that do not meet the conditions for not performing work as the numerator.

[0018] Figure 2 shows the predicted operation rate value A several weeks ahead based on the predicted data of rainfall, snowfall, and wind speed, and the predicted operation rate value B several weeks ahead based on the predicted data of wave height. Figure 3 shows the predicted operation rate value C several weeks ahead based on the predicted data of the occurrence of weather warnings. Further, the determination calculation unit 13 calculates, for example on a weekly basis, the predicted operation rate (not shown) of on-site work several weeks ahead based on the heat index, with the number of days when the daily heat index α shown in Figure 4 exceeds the specified value as the numerator and the above-mentioned actual working days as the denominator. The above-mentioned predicted operation rate values A, B, C... are displayed on the display unit 15.

[0019] The process modification unit 14 reviews the process width and work content of the work process input by the process input unit 12 based on the weather prediction data from the weather prediction data acquisition unit 11 and the predicted operation rate values A, B, C... from the determination calculation unit 13, and modifies the work process. The review of the work content is, for example, when it is predicted that outdoor work cannot be carried out due to weather prediction data, to change it to work in a workplace not affected by the weather or indoor work. Also, when a process delay risk occurs due to the review of the process width, the process modification unit 14 notifies the work manager directly or via the display unit 15 to that effect.

[0020] The display unit 15 displays the work process modified by the process modification unit 14, and as described above, also displays the weather prediction data acquired by the weather prediction data acquisition unit 11 and the predicted operation rate values A, B, C... calculated by the determination calculation unit 13. Further, in the display unit 15, the process delay risk output by the process modification unit 14 may also be displayed.

[0021] The operation of the work process planning system 10 based on the weather prediction data configured as above will be described using Figure 5. The weather prediction data acquisition unit 11 acquires weather prediction data several weeks ahead, for example, from a weather prediction system not shown (S1). The weather prediction data acquired by this weather prediction data acquisition unit 11 is displayed on the display unit 15 (S2).

[0022] Next, the determination calculation unit 13 predicts and determines, for example, whether or not on-site work can be carried out several weeks in advance, based on the weather forecast data acquired in step S1, and further calculates, for example, predicted operating rate values ​​A, B, C... for on-site work several weeks in advance (S3). The predicted operating rate values ​​A, B, C... calculated by the determination calculation unit 13 are displayed in the display unit 15 (S4).

[0023] Next, the process modification unit 14 modifies the work process created by the process creation system 16 and entered by the process input unit 12 based on weather forecast data from the weather forecast data acquisition unit 11 and, for example, the operating rate forecast value for several weeks ahead from the judgment calculation unit 13 (S5). The modified work process and the process delay risk resulting from the modification are displayed on the display unit 15 (S6). After that, the work manager has the on-site work carried out based on the modified work process displayed on the display unit 15.

[0024] As described above, this embodiment provides the following effects (1) to (3). (1) According to the work process planning system 10 using weather forecast data, the determination calculation unit 13 uses weather forecast data acquired by the weather forecast data acquisition unit 11, for example, several weeks in advance, to predict and determine whether or not on-site work can be carried out, for example, several weeks in advance, and determines, for example, predicted operating rate values ​​A, B, C, ... for on-site work several weeks in advance, and the process modification unit 14 modifies the pre-created work process based on the predicted operating rate values ​​A, B, C, ... and the weather forecast data. As a result, work process modifications due to weather can be carried out with high accuracy and with reduced workload for work managers. Accordingly, on-site work safety can be appropriately managed.

[0025] (2) The process modification unit 14 directly or via the display unit 15 notifies the work manager of the risk of process delay caused by the modification of the work process. As a result, the work manager can confirm in advance that a process delay may occur due to the modified work process, thereby preventing disruption to on-site work management.

[0026] (3) The display unit 15 displays not only the revised work process, but also the weather forecast data and operating rate forecast values ​​A, B, C, etc. that formed the basis for the revision. Therefore, the work manager can confirm the revision of the work process, and at the same time, can also confirm the weather forecast data and operating rate forecast values ​​A, B, C, etc. that influenced the revision of the work process.

These embodiments can be implemented in various other forms, and various omissions, substitutions, modifications, and combinations can be made without departing from the spirit of the invention.
