Description

Technical Field

[0002] As the market competition faced by modern shipping companies is becoming increasingly fierce, whether they can provide the best crew configuration and high-quality transportation services according to the performance of the ship and the specific transportation mission requirements is an issue that shipping companies must seriously consider and urgently solve. At present, in most shipping companies, the allocation, scheduling and handover management of crews still adopt the traditional manual management mode. However, in the allocation, scheduling and management of crews in shipping companies, crew transfers are frequent, and the crew involves a lot of professional knowledge and many rigid and prescriptive requirements. It is precisely because of this feature of crew management that there are many drawbacks in the current crew scheduling management of various units. One of them is that all information is passed First, the information is obtained by manually checking the files, but due to the wide variety of crew files, frequent changes of crew certificates, and heavy query workload, managers often query crew information slowly and inaccurately; second, each crew deployment requires searching various files and materials of the crew, which wastes time and has high management costs, but unreasonable deployment still occurs; and, due to the diversity of ship operation status, if there is no crew handover based on the ship operation status, the crew may not be familiar with the ship's operation status in a short time after taking up their posts due to their business capabilities or other circumstances, which may cause the crew to put the ship in an unsafe state within a short time after the handover.

[0051] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] Embodiment 1: This embodiment includes a crew transfer method, as shown in the attached Figure 1 As shown, the method includes:

[0053] S1: The crew member to be handed over submits a handover request to the crew handover system;

[0054] Among them, during the handover process, the crew member to be handed over first puts forward a request to the crew handover system, and then the crew handover system performs subsequent steps according to the request put forward by the crew member to be handed over;

[0055] It is worth noting that in this step, the crew members to be handed over are the crew members who are about to take over their posts;

[0056] S2: The crew handover system responds to the handover demand proposed by the crew to be handed over, and obtains the crew information to be handed over, the position information to be handed over and the ship operation information;

[0057] Wherein, in this step, the information of the crew to be handed over is retrieved from the crew information database in the handover system or obtained by filling in the information by the crew to be handed over; the information of the crew to be handed over includes the age of the crew to be handed over, the service company information of the crew, the job certificate of the crew to be handed over, the performance of the job, the number of operating errors, etc.; wherein, the service company information of the crew is which ship service company the crew to be handed over comes from, and the job certificate of the crew to be handed over includes: seaman's certificate, certificate of competency, service book, MLC physical examination certificate, etc., the performance of the job is the performance of the crew to be handed over in the process of performing the job duties at the position to be handed over; the number of operating errors is the number of behaviors that affect the navigation safety of the ship obtained through inspections, etc. during the performance of the work of the crew to be handed over at the position to be handed over;

[0058] The position information to be handed over is obtained through the position information database of the handover system; the handover position information includes the captain, first mate, chief engineer, chief clerk, etc. The captain is fully responsible for driving and managing the ship. They are responsible for making navigation plans, commanding the ship to enter and leave the port, berthing, and acting as on-site commanders in emergencies; the first mate is a ship driver whose position is only lower than that of the captain. He is responsible for managing the overall work of the deck department under the leadership of the captain. They perform navigation duty, assist the captain in ensuring safe navigation, and are in charge of cargo loading and unloading and transportation and the maintenance of the deck department. When the captain is unable to perform his duties for some reason, he shall act as the captain; the chief engineer is responsible for the technical management and maintenance of the engine department to ensure the normal operation of the ship's machinery and equipment. They need to supervise and guide the engineers to inspect, repair and maintain the equipment; the purser usually leads the purser department, which is responsible for the crew's living services, material management and administrative affairs. They need to coordinate the crew's living needs and ensure the crew's comfort and health; the radio operator is responsible for the ship's communications, including radio communications, sending and receiving signals, etc., to ensure unimpeded information exchange between the ship and the shore or other ships; the electrician is responsible for the maintenance and management of the ship's electrical system, ensuring the normal operation and safe use of electrical equipment;

[0059] The ship operation information is obtained through the ship navigation control system, and the ship operation information includes the ship's speed, heading, whether it deviates from the track, navigation area, etc.;

[0060] S3: The crew handover system evaluates the performance level of the crew to be handed over according to the information of the crew to be handed over, the position information to be handed over and the ship operation information;

[0061] When conducting crew handover work, this embodiment evaluates the performance level of the crew to be handed over by considering the crew information, the position information to be handed over and the ship operation information. According to the different level evaluation results, different operating permissions and performance monitoring methods are released to the crew to be handed over. For crew members with high performance levels, higher operating permissions are released, and for crew members with low performance levels, lower operating permissions are released, so as to keep the crew members within the safety range as much as possible. In addition, different performance monitoring methods are set for crew members of different performance levels, so as to realize differentiated crew monitoring management and improve the targeted monitoring.

[0062] Among them, Figure 2 As shown, the S3 is specifically:

[0063] S3.1: Determine whether to enter the first performance level assessment model or the second performance level assessment model according to the navigation area of ​​the ship and whether it deviates from the waterway;

[0064] Among them, through the review of historical accidents of ships, it is found that accidents are prone to occur during the handover of crew members, especially the handover of crew members in important positions. The reason is that after the intense duty process, the crew members are more or less relaxed and eager to hand over the shift. The crew members who take over are not familiar with the various operating conditions of the ship. If their own ability or knowledge reserves are insufficient, it is easy to fail to discover dangerous factors in time or make wrong decisions. If the ship is operating on the set route, this situation generally does not lead to dangerous situations. If the ship is not on the set route due to wind and waves, it is easy to cause ship safety accidents.

[0065] Therefore, in this step, whether to enter the first performance level assessment model or the second performance level assessment model is determined according to whether the navigation area of ​​the ship is in a dangerous area or deviates from the waterway;

[0066] Specifically, S3.1 is as follows: if the navigation area of ​​the ship is in a dangerous area or the ship deviates from the waterway, enter S3.2; otherwise, enter S3.3;

[0067] S3.2: Use the first performance level assessment model to assess the performance level of the crew members to be handed over;

[0068] The first performance level assessment model is a BP neural network model, wherein the input of the BP neural network model is the information of the crew to be handed over and the information of the position to be handed over, and the output of the BP neural network model is the performance level of the crew to be handed over;

[0069] Furthermore, the BP neural network model includes an input layer, an output layer and a preset number of hidden layers;

[0070] In this embodiment, in order to improve the speed of job performance evaluation as much as possible, the BP neural network model is composed of three layers, that is, the hidden layer is a single-layer structure; Figure 3 The structural diagram of the BP neural network model with three layers is shown in the attached figure. Figure 3 As shown, the crew information to be handed over and the post information to be handed over are transmitted to the input layer, and the input layer transmits the information of the input layer to the hidden layer. After the hidden layer is processed, it is transmitted to the output layer, and the actual output is compared with the expected output in the output layer, and the square error E(w) of the expected output is calculated. If the square error does not meet the model design requirements, the back propagation process is entered. The back propagation process is to apportion the square error to the neurons of the hidden layer, so as to obtain the error signal of the neurons of the hidden layer, and correct the weights of the neurons of the hidden layer according to the error signal, so as to reduce the square error as much as possible; the BP neural network model realizes the accurate calculation of the performance level by repeating the above process;

[0071] Through this step, by inputting the information of the crew members to be handed over and the information of the positions to be handed over into the BP neural network model, on the one hand, with the help of the powerful feature combing and computing capabilities of the BP neural network model, a more accurate performance level assessment result can be obtained; on the other hand, by inputting the information of the crew members to be handed over and the information of the positions to be handed over into the model, the model calculates and matches these two kinds of information, which provides an accurate solution for the calculation of performance level in crew handover.

[0072] Among them, the performance levels are divided into three levels: high, medium and low;

[0073] S3.3: Use the second performance level assessment model to assess the performance level of the crew members to be handed over;

[0074] Wherein, the second performance level assessment model is a performance level assessment model based on a weighting method;

[0075] Among them, the S3.3 is specifically:

[0076] S3.3.1: Set performance level risk assessment indicators;

[0077] Among them, the performance level risk assessment indicators include: age of the crew to be handed over, information on the crew's service company, performance, number of operational errors; seaman's certificate, certificate of competency, service book, MLC medical certificate;

[0078] S3.3.2: Assign importance weight values ​​to the indicators;

[0079] In this embodiment, the evaluation indicators are scored by experts, and then the scores are normalized to obtain the important weight values ​​of each indicator;

[0080] S3.3.3: Assign values ​​to the risk assessment indicators of the crew members to be handed over;

[0081] The value assignment process for the age of the crew member to be handed over a1 is as follows: if the age of the crew member to be handed over is more than 10 years, 10 points are assigned; if the age of the crew member to be handed over is less than or equal to 10 years, 8 points are assigned;

[0082] The service company information a2 of the crew member is assigned a value as follows: if the service company information of the crew member is a Class I service company, 10 points are assigned; if the service company information of the crew member is not a Class I service company, 6 points are assigned;

[0083] The performance a3 is assigned a value as follows: if the crew has no poor performance record in the past year, 10 points are assigned; if the crew has a poor performance record in the past year, 0 points are assigned;

[0084] The number of operation errors a4 is assigned a value as follows: if the number of operation errors of the crew member in the past year is greater than 2 times, 3 points are assigned; if the number of operation errors of the crew member in the past year is less than or equal to 2 times, 10 points are assigned.

[0085] The seaman's certificate, competency certificate, service book, and MLC medical certificate a5 are assigned values ​​as follows: if the seaman has 4 of the above certificates, 10 points are assigned; if the seaman has 3 of the above certificates, 8 points are assigned; if the seaman has 2 of the above certificates, 2 points are assigned;

[0086] S3.3.4: Calculate the performance risk assessment score F of the crew member to be handed over according to the risk assessment index value and the importance weight value assigned to the index;

[0087] Among them, the calculation formula of S3.3.4 is:

[0088]

[0089] in, They are respectively the age of the crew member to be handed over, the service company information of the crew member, the job performance, the number of operational errors, and the importance weight of the certificate;

[0090] S3.3.5: Determine the performance risk assessment level of the crew member to be handed over according to the performance risk assessment score F of the crew member to be handed over;

[0091] Among them, the S3.3.5 is specifically:

[0092] ;

[0093] In this step, since the ship is in a relatively safe state in the instantaneous state of the handover, a relatively simple risk assessment model is used to assess the performance risk of the crew to be handed over in order to save computing resources and improve the assessment speed.

[0094] S4: granting different operation permissions to the crew members to be handed over according to their risk levels of performing their duties.

[0095] Among them, the crew members with low performance risk level are granted high operation authority; the crew members with medium performance risk level are granted medium operation authority; the crew members with high performance risk level are granted low operation authority;

[0096] In this step, it is worth emphasizing that when a crew member with low operating authority is granted key operations, confirmation by a superior administrator is required. The key operations are operations that affect the safety of the ship's operation.

[0097] S5: assigning different supervision procedures to the crew members to be handed over according to their performance risk levels;

[0098] Among them, the exemption from supervision procedure is adopted for the crew members with high job risk level; the video supervision procedure is adopted for the crew members with medium job risk level; and the video supervision procedure and irregular on-site supervision procedure are adopted for the crew members with low job risk level.

[0099] Among them, during the handover process, the responsibilities and division of labor of the handover personnel should be clearly defined to ensure that the handover process is carried out in an orderly manner;

[0100] In addition, the handover content includes handover materials: ship certificates, navigation logs, engine logs, cargo records, equipment maintenance records, crew lists, etc.; after the handover, the system will hand over pending tasks, notification messages, positions, roles, and responsibilities.

[0101] Embodiment 2: This embodiment includes a crew handover system, which adopts a crew handover method of embodiment 1, and the system includes:
