Description

Technical Field

[0001] The present invention mainly relates to an apparatus, a method, and a program for managing the working hours of ship crew members.

Background Art

[0002] With the legislative purpose of fulfilling the need for workers to lead a life worthy of human beings, the Labor Standards Act sets minimum standards for working conditions. Specifically, working hours, wages, holidays, etc. are specifically defined.

[0003] In order to manage the working hours of workers, for example, a time recorder is introduced to record the arrival and departure times. According to the time recorder, the difference between the arrival time and the departure time is presumed to be the working hours.

[0004] In addition, various work management apparatuses that can accurately grasp the actual working hours by using a computer have been proposed. For example, Patent Document 1 discloses a system that manages the constrained time, which is the time when an employee is actually at the work site, based on the position information of the employee. Also, Patent Document 2 discloses a work management apparatus that estimates working hours from work logs generated by a computer used by an employee, calendar schedules, etc.

Summary of the Invention

Problems to be Solved by the Invention

[0006] Regarding the labor management of ship crew members, the revised Ship Crew Act implemented in April 2022 imposes an obligation on shipowners to establish a labor management system and appropriately operate the labor management system regarding the labor of crew members. As the background, it can be cited that the working environment of crew members is often severe and the working hours tend to be long.

[0007] However, in the case of ship crew members, it is not possible to evaluate the actual working hours only by managing the arrival and departure times. In particular, regarding the operation of ships, since there are binding hours and rest hours according to the roles of crew members, the working hours estimated from the arrival and departure times often differ from the actual working hours. Also, it is not easy to manage the actual working hours based on a computer system at the ship or port site.

[0008] Here, the inventors of the present invention have found the following points. Since the operation schedule of a ship is planned in advance, it is possible to grasp to a certain extent in advance the possibility of exceeding the working hours stipulated by law.

[0009] An object of the present invention is to realize an apparatus or the like that contributes to shipowners and domestic shipping operators to realize the operation of a ship that satisfies appropriate working conditions for crew members by grasping the working hours of ship crew members in advance.

Means for Solving the Problem

[0010] In order to solve the above problems, the labor management device (100, 200, 300) of the present invention includes an input unit (101) that inputs shipping information including departure place information indicating the departure place of the ship, first cargo handling start time information indicating the time when the operation of loading goods onto the ship at the departure place starts, first cargo handling end time information indicating the time when the loading operation ends, departure time information indicating the time when the ship leaves the departure place, and arrival place information indicating the arrival place of the ship; A period specifying unit (104) that obtains the navigation period of the ship based on the departure place information, the arrival place information, and the speed information indicating the speed of the ship, and obtains the cargo handling work period based on the first cargo handling start time information and the first cargo handling end time information; A labor hour calculation unit (105) that obtains the labor hours of each crew member related to the operation of the ship based on the navigation period and the cargo handling work period; A labor condition determination unit (106) that determines whether the labor hours satisfy a predetermined rule; And an output unit (103) that outputs the determination result of the labor condition determination unit.

Effect of the Invention

[0011] According to the labor management device and the like of the present invention, when establishing the operation schedule of a ship, it is possible to know whether the labor conditions of the crew are appropriate in light of laws and regulations, etc., so that it is possible to operate the ship under appropriate labor conditions.

Modes for Carrying Out the Invention

[0013] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0014] Note that the present invention means the invention described in the claims or the section of means for solving the problems, and is not limited to the following embodiments. Also, at least the words in parentheses mean the words described in the claims or the section of means for solving the problems, and are not limited to the following embodiments either.

[0015] The configurations and methods described in the dependent claims of the claims are arbitrary configurations and methods in the invention described in the independent claim of the claims. The configurations and methods of the embodiments corresponding to the configurations and methods described in the dependent claims, and the configurations and methods described only in the embodiments without being described in the claims are arbitrary configurations and methods in the present invention. Even the configurations and methods described in the embodiments when the scope of the claims is broader than the description of the embodiments are arbitrary configurations and methods in the present invention in the sense that they are examples of the configurations and methods of the present invention. In any case, by being described in the independent claim of the claims, they become the essential configurations and methods of the present invention.

[0016] The effects described in the embodiments are the effects in the case of having the configurations of the embodiments as examples of the present invention, and are not necessarily the effects of the present invention.

[0017] When there are a plurality of embodiments (including variations. The same shall apply hereinafter), the configurations disclosed in each embodiment are not limited to each embodiment alone, and can be combined across embodiments. For example, the configurations disclosed in one embodiment may be combined with other embodiments. Also, the configurations disclosed in each of the plurality of embodiments may be collected and combined.

[0018] The problems described in the problems to be solved by the invention are not known problems, but are discoveries made independently by the inventor, and are facts that affirm the inventiveness of the invention together with the configurations and methods of the present invention.

[0019] 1. Embodiment 1 (1) Configuration of Labor Management Device 100 First, with reference to FIG. 1, the configuration of the labor management device 100 of the present embodiment will be described. The labor management device 100 has an input unit 101, a control unit 102, and an output unit 103. The control unit 102 realizes the functions of a period specifying unit 104, a working hour calculation unit 105, and a labor condition determination unit 106.

[0020] In addition, the labor management device 100 can access databases of a ship master A, a distance table master B, a crew master C, and a labor condition master D. The contents of these databases will be described later. These databases may be provided inside the labor management device 100 or outside the labor management device 100, for example, in a server device. Each database is composed of an auxiliary storage device such as a hard disk, a CD-ROM, a BD-ROM, or a USB memory, but may also be composed of a main storage device consisting of a random access memory.

[0021] The input unit 101 inputs information necessary for a period specifying unit 104, which will be described later, to obtain a navigation period and a cargo handling work period. In the present embodiment, the departure place information indicating the departure place of the ship, the time indicating the time when the "loading work" of "goods" onto the ship at the departure place starts (corresponding to the "first cargo handling start time information"), the time indicating the time when the "loading work" ends (corresponding to the "first cargo handling end time information"), the departure time information indicating the time when the ship departs from the departure place, and the arrival place information indicating the arrival place of the ship are input as shipping information. The input may be performed by an operator operating the labor management device 100 using an input device such as a keyboard, or by reading a file in which the pre-created shipping information is recorded. Also, it does not prevent the input of information other than these. Here, "Indicating" includes not only the case of directly indicating the target information but also the case of indirectly indicating the target information. Examples of the former include port names or place names, times, and examples of the latter include latitude and longitude, port codes, and periods calculated from a reference time. "Goods" may be any of solids (including powders), liquids, and gases. For example, ores, cement, cargo, heavy oil, liquefied natural gas, chemicals, and various gases are also included in goods. Also, the container itself is included in goods. "Loading work" may include not only the actual loading work but also the preparatory work for loading and the post-processing work after loading. Also, the target of loading may be a person in addition to goods. The "time" may include year and month in addition to hour and minute. Further, it may include seconds.

[0022] In addition, the input unit 101 may further input the cargo handling start time information (corresponding to the "second cargo handling start time information") indicating the "time" to start the "loading and unloading operation" of the goods from the ship at the arrival location, and the cargo handling end time information (corresponding to the "second cargo handling end time information") indicating the "time" to end the "loading and unloading operation". Here, the "loading and unloading operation" may include, in addition to the actual loading and unloading operation, the preparatory work for loading and unloading and the post-processing work for loading and unloading. Also, the object of loading and unloading may be a person in addition to goods.

[0023] The period specifying unit 104 obtains the navigation period of the ship based on the departure location information, arrival location information, and speed information indicating the speed of the ship input by the input unit 101. Also, the period specifying start unit 104 obtains the cargo handling work period at the departure location based on the cargo handling start time information (corresponding to the "first cargo handling start time information") and the cargo handling end time information (corresponding to the "first cargo handling end time information") at the departure location. When the input unit 101 inputs the cargo handling start time information (corresponding to the "second cargo handling start time information") and the cargo handling end time information (corresponding to the "second cargo handling end time information") at the arrival location, the cargo handling work period at the arrival location is obtained based on these. In addition, the period specifying unit 104 may also obtain other periods. In this embodiment, the standby periods provided before and after the cargo handling work period are also obtained. Also, among the navigation periods, the berthing operation period, which is the period related to departure from and arrival at the quay, is also obtained.

[0024] Figure 2 is a specific example of the input screen for ship allocation information. How various calculations are performed and how they are displayed according to the information to be input will be described in chronological order. In Figure 2, the information to be input is indicated by a thick frame, and the information calculated and displayed based on the input information is indicated by a thin frame.

[0025] First, when there are multiple ships, enter the ship name. If the candidates for the ship name are known in advance, they can be registered in the pull-down menu and selected from the pull-down menu for input. In FIG. 2, the Tokuyama Maru is displayed as the ship name, together with the ship code 001 associated with the ship name.

[0026] When the ship name is entered, the labor management device 100 accesses the ship master A. FIG. 3 is a specific example of the database constituting the ship master A. The ship master A is composed of a ship code, ship name, ship type, average speed (knots / hour), and maximum load capacity (tons). The ship type is information indicating the use of the ship, and in FIG. 3, a cement carrier, a special tanker, and a cargo ship are given as examples. The labor management device 100 reads out the speed corresponding to the ship name input from the input unit 101 from the ship master A and displays it in the column of the average speed. In FIG. 2, 11 knots / hour is displayed as the average speed.

[0027] Second, enter the departure place of the ship. The departure place information and the arrival place information described later can also be registered in the pull-down menu and selected from the pull-down menu for input if the candidate places are known in advance. In FIG. 2, Tokuyama is entered as the departure place information.

[0028] Third, enter the departure date, the start time of the cargo handling at the departure place, and the end time of the cargo handling at the departure place. In FIG. 2, the departure date is August 2, 2023, the start time of the cargo handling is 8:00 on the same day, and the end time of the cargo handling is 14:00. The period specifying unit 104 of the labor management device 100 calculates and displays the cargo handling time (corresponding to the "cargo handling work period") at the departure place based on this information. In FIG. 2, 6 hours is displayed.

[0029] In the present embodiment, it is also possible to enter the standby time 1, which is the buffer time before the start time of the cargo handling, and the standby time 2, which is the buffer time after the end time of the cargo handling. The buffer time is set so as to cope with changes in the cargo handling work time due to the weather on the day and unexpected situations. In FIG. 2, 0.5 hours is entered for each, but a predetermined time may be automatically set.

[0030] Fourth, input the departure time. In FIG. 2, the departure time of 15:30 is input. When the departure time is input, the time from the time when the cargo handling is completed and the standby time has elapsed until the departure time is calculated as the waiting time and displayed. In FIG. 2, since the time when the standby time has elapsed is 14:30, 1 hour is displayed.

[0031] Fifth, input the destination of the ship. In FIG. 2, Uwajima is input as the destination information.

[0032] When the destination is input, the labor management device 100 accesses the distance table master B. FIG. 4 is a specific example of the database constituting the distance table master B. In the distance table master B, the departure place candidates and the destination place candidates are arranged in the horizontal direction and the vertical direction respectively, and the distance (nautical miles) between two points is recorded. The period specifying unit 104 of the labor management device 100 reads out the distance corresponding to the departure place and the destination input from the input unit 101 and displays it in the column of the navigation distance. In FIG. 2, 75 nautical miles is displayed as the navigation distance.

[0033] In this embodiment, the distance between the departure place and the destination is obtained using the distance table master B. Instead of this, the distance between the departure place and the destination may be obtained using the checkpoint master E used in Embodiment 2 and Embodiment 3. Details will be described in Embodiment 2.

[0034] The period specifying unit 104 of the labor management device 100 calculates and displays the navigation time based on the navigation distance and the average speed. In the case of FIG. 2, since the navigation distance is 75 nautical miles and the average speed is 11 knots / hour, 6.8 hours is displayed as the navigation time. Furthermore, the labor management device 100 calculates and displays the arrival time at the destination from the departure time and the navigation time. In FIG. 2, since the departure time is 15:30 and the navigation time is 6.8 hours, 22:18 is displayed as the arrival time.

[0035] Sixthly, input the cargo handling start time and the cargo handling end time at the arrival port. In Fig. 2, the cargo handling start time is input as 10:00 on August 3rd, and the cargo handling end time is input as 15:00. Based on this information, the period specifying unit 104 of the labor management device 100 calculates and displays the cargo handling time at the arrival port (corresponding to the "cargo handling work period"). In Fig. 2, 5 hours are displayed. Also, when the cargo handling start time is input, the time from the arrival time to the start point of the standby time before the cargo handling start time is calculated as the standby time and displayed. In Fig. 2, since the arrival time is 22:18 and the start point of the standby time is 9:30 the next day, 11.2 hours are displayed.

[0036] In this embodiment, the standby time 1 and the standby time 2 may be input at the arrival time in the same way as at the departure time. In Fig. 2, 0.5 hours are input for each, but the predetermined time may be automatically set.

[0037] In Fig. 2, the information is input in the order from the first to the sixth, but the input order is arbitrary.

[0038] Based on the navigation period and the cargo handling work period obtained by the period specifying unit 104, the labor time calculation unit 105 obtains the labor time of each "crew member" related to the "operation" of the ship. More specifically, the labor time calculation unit 105 obtains the labor time based on the "role" of each crew member. Here, "Operation" includes not only the operation of the ship, but also the preparations and post-processing necessary for the operation, and the preparations and post-processing necessary to achieve the purpose of the operation. "Crew member" includes not only those involved in the operation of the ship, but also those involved in the operations necessary to achieve the purpose of the ship's operation. "Role" includes, for example, positions associated with roles such as the captain, chief engineer, navigator, and engineer.

[0039] In this embodiment, the working hours calculation unit 105 accesses the crew master C and reads out the information of the crew corresponding to the ship name. FIG. 5 is a specific example of the database constituting the crew master C. The crew master C is composed of a crew code, a role (position), a working period, and the ship name in charge.

[0040] The crew code is a code assigned to each crew member and is used to identify an individual. The role (position) is a qualification in the operation of a ship. The working period is the period during which each role (position) is engaged in work and is linked to the role (position). In FIG. 5, for example, the first-class navigator has the standby period and the navigation period as the working periods. The deck officer, seaman, engineer officer, and first-class engineer have the standby period, the cargo handling period, and the navigation period as the working periods. The captain has the standby period, the berthing and unberthing operation period, and the period of navigating in narrow waters as the working periods. The berthing and unberthing operation period is the period related to leaving and approaching the shore, and can be determined, for example, as 30 minutes after departure and 30 minutes before arrival during the navigation period. Note that these allocations are not limited to the allocations in FIG. 5 and can be arbitrarily determined. In addition, those who perform onshore duties without boarding the ship may also be included in the crew master C as "crew members" of the present invention and managed.

[0041] In the example of FIG. 2, the working hours calculation unit 105 reads out the crew code and role of the crew in charge of the Tokuyama Maru. Specifically, it reads out the information of the captain (01), first-class navigator (11), deck officer (21), seaman (31), engineer officer (41), and first-class engineer (51) from the crew master C.

[0042] FIG. 6 shows the calculation and display states of the period specifying unit 104 and the working hours calculation unit 105. In the upper part of FIG. 6, the navigation period, cargo handling period, and standby period specified by the period specifying unit 104 are displayed on a time-axis scale. In FIG. 6, the cargo handling period at the destination is omitted, but this may also be displayed together. Furthermore, the subsequent navigation may also be displayed together.

[0043] In the middle part of FIG. 6, for each crew member read out by the working hours calculation unit 105, the working periods corresponding to the roles of the respective crew members are displayed. For example, for the captain (01), the standby period and the berthing and unberthing operation periods are assigned as the working periods. For the first-class navigator (11), the standby period and the navigation period are assigned. For the deck chief (21), deckhands (31), engineer-in-charge (41), and first-class engineer (51), the standby period, the cargo handling operation period, and the navigation period are assigned. However, in the example of FIG. 6, the first half of the cargo handling operation period is assigned to the deck chief (21) and deckhands (31), and the second half is assigned to the engineer-in-charge (41) and first-class engineer (51). Also, in the example of FIG. 6, the first half of the navigation period is assigned to the deck chief (21) and first-class engineer (51), and the second half is assigned to deckhands (31) and engineer-in-charge (41). These allocation methods may be determined according to predetermined rules based on the number of people required for the work in each period. For example, taking into account the length of the working period of each crew member, the number of people required for the work, the balance of the roles (positions) and years of experience of the crew members assigned simultaneously, and the working hours in previous and subsequent different voyages, etc., the working hours of each crew member can be evenly allocated so that they are as equal as possible.

[0044] The working conditions determination unit 106 determines whether the working hours of each crew member obtained by the working hours calculation unit 105 satisfy predetermined working conditions (corresponding to the "predetermined rules"). In the present embodiment, the working conditions determination unit 106 accesses the working conditions master D to read out the working conditions, and determines whether the working hours of each crew member satisfy the working conditions.

[0045] FIG. 7 is a specific example of the database constituting the working conditions master D. The working conditions master D is composed of an identification number (ID), a classification of working conditions, the working conditions, and a message output when the working conditions are not satisfied. The working conditions are, for example, the working conditions defined by the Seafarers Act that are stored in advance.

[0046] In FIG. 6, for example, when the working hours of the first-class navigator (11) exceed 8 hours a day, the labor condition determination unit 106 determines that the working hours of the first-class navigator (11) do not meet the labor conditions, and instructs the output unit 103 to output the determination result. Specifically, the labor condition determination unit 106 reads the message with ID (01) from the labor condition master D, and the output unit 103 points to the working period that does not meet the labor conditions on the screen of FIG. 6 and displays a message "The working hours per day exceed 8 hours."

[0047] When the message is displayed, the determination by the labor condition determination unit 106 is performed again with the conditions changed. For example, through the input unit 101, modifications such as inserting breaks to divide the working period, changing the order of shift work, increasing the number of people, changing the start time of the cargo handling time, etc. can be made, and the determination by the labor condition determination unit 106 can be executed again. By repeating until the message no longer appears, an operation schedule for the ship that meets the labor conditions can be established.

[0048] The output unit 103 outputs the determination result of the labor condition determination unit 106. The output unit 103 may output information other than the determination result. For example, it may output the navigation period and cargo handling work period obtained by the period specifying unit 104, and the working hours of each crew member obtained by the working hour calculation unit 105. The example in FIG. 6 is an example of outputting all of these. The output destination of the output unit 103 may be a display or a speaker, or the determination result may be recorded in a file and stored in a storage unit (not shown).

[0049] (2) Operations of the labor management device 100 Next, with reference to FIG. 8, the operations of the labor management device 100 will be described. FIG. 8 shows not only the labor management method executed by the labor management device 100 but also the processing procedures of the labor management program executable by the labor management device 100. And these processes are not limited to the order shown in FIG. 8. That is, the order may be changed as long as there are no restrictions such as using the result of the previous step in a certain step. The same applies to other embodiments.

[0050] From the input unit 100 of the labor management device 100, shipping information including the departure place information indicating the departure place of the ship, the cargo handling start time information indicating the time to start the operation of loading goods onto the ship at the departure place, the cargo handling end time information indicating the time to end the loading operation, the departure time information indicating the time when the ship leaves the departure place, and the arrival place information indicating the arrival place of the ship is input (S101). The period specifying unit 104 obtains the navigation period of the ship based on the departure place information, arrival place information, and speed information indicating the speed of the ship input in S101, and obtains the cargo handling work period based on the cargo handling start time information and the cargo handling end time information (S102). The labor time calculation unit 105 obtains the labor time of each crew member related to the operation of the ship based on the navigation period and the cargo handling work period obtained in S102 (S103). The labor condition determination unit 106 determines whether the labor time satisfies the predetermined labor conditions (S104). The output unit 103 outputs the determination result of the determination performed in S104 (S105).

[0051] (3) Parentheses As described above, according to the present embodiment, since the labor time of each crew member is obtained based on the shipping information and it is determined whether the labor time satisfies the labor conditions, it is possible to know whether the labor conditions of the crew members are appropriate in light of laws and regulations when establishing the operation schedule of the ship. In addition, the operation of the ship includes at least the navigation period and the cargo handling work period, and since the navigation period and the cargo handling work period are extracted from the shipping information, it is possible to obtain the accurate labor time of each crew member in light of the role of each crew member.

[0052] 2. Embodiment 2 (1) Configuration of the labor management device 200 In Embodiment 1, the working hours of each crew member were determined based on the ship allocation information, and it was determined whether each working hour satisfied the working conditions. However, based on the ship allocation information, a detailed route can be obtained, and a warning can be given for the operation of the ship based on the risk factors in the route and the port. Furthermore, by checking such risk factors, the working period of each crew member can also be adjusted. In this embodiment, the labor management device 200 based on these will be described.

[0053] First, with reference to FIG. 9, the configuration of the labor management device 200 of this embodiment will be described. The same figure numbers are assigned to the functional blocks and databases common to FIG. 1, and the description of Embodiment 1 is cited. The labor management device 200 includes an input unit 101, a control unit 102, and an output unit 103. The control unit 102 realizes the functions of a period specifying unit 104, a working hour calculation unit 105, a working condition determination unit 106, a route calculation unit 107, a risk factor acquisition unit 108, and a risk / warning information generation unit 109.

[0054] In addition, the labor management device 200 can access databases such as a ship master A, a crew member master C, a working condition master D, and a checkpoint master E as databases. That is, the labor management device 200 of this embodiment has a checkpoint master E instead of the distance table master B of Embodiment 1.

[0055] The input unit 101 inputs information necessary for the route calculation unit 107 described later for obtaining a route and the period specifying unit 104 for obtaining a navigation period and a cargo handling work period. The information to be input is basically the same as that in Embodiment 1.

[0056] Based on the departure place information and arrival place information input from the input unit 101, the route calculation unit 107 obtains the route of the ship. The route is indicated by, for example, a departure place, an arrival place, and a checkpoint that is a waypoint between the departure place and the arrival place. In this embodiment, the route calculation unit 107 accesses the checkpoint master E to read the departure place, the arrival place, and the checkpoints between the departure place and the arrival place.

[0057] FIG. 10 is a specific example of a database constituting the checkpoint master E. The checkpoint master E is a table consisting of the name of the checkpoint, the latitude and longitude of the checkpoint. Since the checkpoint master E has information on the latitude and longitude of the checkpoint, the distance between checkpoints can be obtained. Also, adjacent checkpoints can be searched. In the present embodiment, it is assumed that the checkpoint master E registers information on ports in addition to checkpoints.

[0058] Which checkpoint to pass through among the checkpoints existing between the departure point and the arrival point can be set by an arbitrary rule. For example, when moving so that the distance from the departure point to the arrival point is the shortest, among the combinations connecting the departure point and the arrival point, the combination with the shortest distance may be selected. Alternatively, more appropriate routes may be selected according to the situation using other conditions. For example, in winter, since the sea is often rough on the Sea of Japan side, a route with a shorter distance of sailing on the Sea of Japan side may be selected. Specifically, for example, when selecting a route from Osaka to Akita, although the distance is shorter when passing through the Kanmon Strait than when passing through the Tsugaru Strait, the former has a longer distance of sailing on the Sea of Japan side than the latter. Therefore, in winter, a route passing through the Tsugaru Strait may be selected.

[0059] Figure 11 shows the operation and display states of the route calculation unit 107. In the upper left of Figure 11, there is an area for inputting the departure and arrival locations. In Figure 11, for example, it is assumed that the cargo is cement and the Tokuyama Maru is a dedicated ship for cement transportation. That is, it is assumed that cement is loaded at Tokuyama, unloaded at Uwajima, the empty ship is sent back to Tokuyama, cement is loaded again at Tokuyama, unloaded at Mizushima, and the empty ship is sent back to Tokuyama. In this way, the ship allocation information can input the ship allocation information corresponding not only to a single voyage but also to multiple voyages. Hereinafter, only the voyage between Tokuyama and Uwajima among these will be taken up and explained.

[0060] When the ship allocation information is input from the input unit 101, the route calculation unit 107 obtains the distance between each checkpoint from the departure location to the arrival location using the latitude and longitude information read from the checkpoint master E, and also obtains the distance from the departure location to the arrival location. For example, in the upper right of Figure 11, the names of the departure location, the checkpoints passed through, and the arrival location are displayed together with the distance between checkpoints and the cumulative distance from the departure location. Further, on the lower side of Figure 11, the departure location, the checkpoints passed through, and the arrival location are mapped and displayed on the map. Note that the checkpoints passed through may be configured to be changeable while viewing the route on the map. Also, the passing time of each checkpoint may be calculated and displayed.

[0061] Then, the route calculation unit 107 outputs the obtained distance between checkpoints and the integrated distance to the period specifying unit 104, and the period specifying unit 104 obtains the voyage period mainly using the cumulative distance. In this way, by using the checkpoint master E, a more accurate distance considering the checkpoints can be obtained.

[0062] The risk factor acquisition unit 108 "acquires" the risk factors for the ship based on the route obtained by the route calculation unit 107. Examples of risk factors include at least one of tide, lunar age, flow velocity or direction of tidal current, and distinction between flood tide and ebb tide. Such information can be obtained, for example, from the database of the Japan Meteorological Agency. That is, information on the route obtained by the route calculation unit 107, such as the location of checkpoints and ports, is specified, and the tide, etc. at that location can be acquired. Other risk factors include weather, precipitation and snowfall amounts, temperature, humidity, sunrise time and sunset time, and other events that affect the operation of the ship, etc. Also, as another example of risk factors, the risk factors possessed by the route itself obtained by the route calculation unit 107 may be acquired. For example, there are reefs, shoals, narrow waterways such as straits, etc. If such information is registered in the checkpoint master E as the accompanying information of the checkpoint, it may be acquired from the checkpoint master E. Here, "acquire" includes not only the case of acquiring information indicating risk factors from outside the labor management device, but also the case of acquiring by performing calculations inside the labor management device.

[0063] Figure 12 shows the state of displaying the risk factors acquired by the risk factor acquisition unit 108. The risk factors are displayed corresponding to the display in Figure 2. Specifically, the risk factor acquisition unit 108 acquires and displays the tide and lunar age at the departure and arrival locations, the flow velocity and direction of the tidal current at each checkpoint, and the distinction between flood tide and ebb tide.

[0064] For example, in Figure 12, the tide at each time zone in Tokuyama, which is the departure location, is displayed numerically and graphically. And the time zones when the ship is berthed in Tokuyama are highlighted with thick frames. Thereby, it is possible to confirm the ebb and flow of the tide during the berthed time zones. For example, if the tide level has dropped below the reference value at the time of departure, the departure time can be adjusted forward or backward to avoid danger. The same display is also made in Uwajima, which is the arrival location.

[0065] In addition, in FIG. 12, the flow direction and velocity of the tidal current at each checkpoint, as well as the distinction between flood tide and ebb tide, are displayed. For example, at 0:00, the flow direction is 0° and the velocity is 1.6 knots. Also, the velocity is displayed as a graph to enhance visibility, and the distinction between flood tide and ebb tide is shown by changing the color of the graph. And the time zone when passing through each checkpoint is highlighted with a thick frame. Furthermore, the direction of the ship's progress is shown. Thereby, the flow direction and velocity of the tidal current when passing through the checkpoint can be confirmed, and the dangers during navigation can be confirmed in advance. In FIG. 12, the information on the flow direction and velocity of the tidal current and the distinction between flood tide and ebb tide is currently displayed only when the checkpoint is a narrow channel, but it may also be displayed at other checkpoints.

[0066] Based on the risk factors acquired by the risk factor acquisition unit 108, the risk / warning information generation unit 109 generates risk / warning information for the ship's navigation and instructs the output unit 103 to output the risk / warning information. Specifically, for each risk factor, when it exceeds or falls below a predetermined limit value, risk / warning information is generated. For example, when sailing from the departure port or to the arrival port, or through shoals or narrow channels, when it falls below a predetermined limit value, a message prompting attention is generated and displayed.

[0067] For example, in FIG. 12, when the reference tide level is 230 cm, the color of the graph for the time period below 230 cm may be changed for display, or a message such as "Tide Caution: Below 230 cm" may be displayed. Also, in FIG. 12, when the flow velocity or direction in a narrow channel exceeds a predetermined speed or is in a predetermined direction, a message such as "Caution: Flow Velocity and Direction" may be displayed. Furthermore, the color of the graph indicating a value deviating from the reference may be changed for display.

[0068] The output unit 103 outputs the danger / warning information generated by the danger / warning information generation unit 109. The output unit 103 may output information other than the danger / warning information. For example, it may output the route obtained by the route calculation unit 107 or the danger factors obtained by the danger factor acquisition unit 108. The examples in FIGS. 11 and 12 are examples of outputting these.

[0069] (2) Parentheses As described above, according to this embodiment, since the danger factors for the ship are acquired based on the ship allocation information and the danger / warning information for the ship's navigation is generated based on these danger factors, when making a ship operation schedule, it is possible to confirm whether the working hours meet the working conditions, and at the same time, confirm the danger / warning information regarding the ship's navigation. Furthermore, since the selection of crew members etc. can be carried out based on the danger / warning information, the risk of accidents can be further reduced.

[0070] 3. Embodiment 3 (1) Configuration of the labor management device 300 In Embodiment 2, by obtaining a route based on the ship allocation information and acquiring the danger factors on the route, it was possible to grasp in advance the danger of the ship's operation. However, when this danger factor affects the working hours of each crew member, the configuration of Embodiment 1 can be used to obtain the working hours reflecting the danger factor and determine whether the working conditions are met. Hereinafter, the labor management device 300 of this embodiment will be described.

[0071] First, the configuration of the labor management device 300 of this embodiment will be described with reference to FIG. 13. The same figure numbers are assigned to the functional blocks and databases common to FIGS. 1 and 9, and the descriptions of Embodiments 1 and 2 are cited. The labor management device 300 includes an input unit 101, a control unit 102, and an output unit 103. The control unit 102 realizes the functions of a period specifying unit 104, a working hour calculation unit 105, a working condition determination unit 106, a route calculation unit 107, a danger factor acquisition unit 108, a danger / warning information generation unit 109, and a human limit period specifying unit 110.

[0072] The route calculation unit 107 outputs the obtained route to the human deadline specifying unit 110.

[0073] The risk factor acquisition unit 108 outputs, to the human deadline specifying unit 110, among the acquired risk factors, the risk factors that affect the working hours of the crew. For example, when passing through a narrow channel, if there is a rule that the captain must instruct the operation of the ship, the risk factor acquisition unit 108 outputs information on the narrow channel existing on the route to the human deadline specifying unit 110. This rule can be registered as accompanying information of the checkpoint in the checkpoint master E, for example, and can be read from the checkpoint master E and used.

[0074] The human deadline specifying unit 110 obtains a human deadline, which is a period during which human restrictions occur on the operation of the ship, based on the route obtained by the route calculation unit 107 and the risk factors obtained by the risk factor acquisition unit 108. In the present embodiment, based on the positions of the entrance and exit of the narrow channel existing on the route obtained by the route calculation unit 107, the time when the ship enters the narrow channel and the time when the ship passes through the narrow channel are obtained, and the period specified by these times is set as the human deadline. Then, the human deadline specifying unit 110 outputs the human deadline to the working hour calculation unit 105.

[0075] The working hour calculation unit 105 obtains the working hours of each crew member related to the operation of the ship based on the navigation period and the cargo handling operation period obtained by the period specifying unit 104, in addition to the human deadline.

[0076] FIG. 14 shows the calculation and display states of the period specifying unit 104 and the working hour calculation unit 105. In the middle of FIG. 14, for each crew member read by the working hour calculation unit 105, a period corresponding to the role of each crew member is displayed. Here, when passing through a narrow channel, the captain must directly instruct the operation of the ship. Therefore, for the captain (01), in addition to the standby period and the berthing operation period, the narrow channel passing period is assigned as the working period.

[0077] As another example of the human restricted period, in the case of an area with many shallows or reefs, when the tidal current exceeds a predetermined level, when the wind speed exceeds a predetermined level, etc. can be cited. Also, as a human restriction during such a human restricted period, for example, a rule that the captain is present during ship operation or a rule that a crew member with a certain number of years of experience operates the ship may be applied. These rules can be set arbitrarily.

[0078] (2) Parentheses According to this embodiment, since the human restricted period in which human restrictions occur on the operation of the ship is obtained based on the route and risk factors and reflected in the working hours according to the role of each crew member, the working hours of each crew member associated with the operation of the ship can be obtained more accurately.

[0079] 4. Other Embodiments Embodiments 1 to 3 mainly target cargo ships for transporting goods, but may also target passenger ships for transporting people. That is, the objects of loading onto the ship and unloading from the ship may be people instead of goods. In this case, "loading operation" is read as "boarding guidance", "unloading operation" is read as "disembarkation guidance", "cargo handling start time information" is read as "boarding start time information" or "disembarkation start time information", "cargo handling end time information" is read as "boarding end time information" or "disembarkation end time information", and "cargo handling operation period" is read as "boarding guidance period".

The terminal device 20 performs input from the user and output to the screen etc. using, for example, a browser.

[0082] Alternatively, the labor management device 100 etc. may be realized as the terminal device 20 as shown in Fig. 15(b). That is, the labor management device 100 etc., which is the terminal device 20, performs predetermined calculations etc. based on the input from the user's terminal device 20, and outputs the results of the calculations etc. to the screen etc. of the terminal device 20. The results of the calculations etc. may be saved in the server device 10. Each of the masters A to E may be provided in the terminal device 20, but each of the masters A to E may be saved in the server device 10 and read out as appropriate when necessary. Note that the terminal device 20 can be realized by, for example, downloading and saving the labor management program of the present invention from the server device 10 and executing it.

[0083] 6.
