Abstract
Description
Technical Field
[0001] This invention relates to ship design technology, and more particularly to a method for evaluating the layout of ship work compartments based on ergonomic analysis. Background Technology
[0002] Link analysis uses "links" to represent human-machine relationships. Links encompass various types of human behavior, including observation, walking, receiving instructions, communication, and operating equipment. There are two types of links: corresponding links and successive links. Links that can be completed through direct interaction between personnel and personnel / equipment during a task are called corresponding links. Links that require multiple consecutive actions to complete during a task are called successive links. Considering the layout of shipboard workrooms, visual links, auditory links, and operational links are corresponding links, while walking links are successive links.
[0003] The traditional link analysis method involves the following steps: First, the existing work processes and personnel requirements need to be organized, clarifying information such as equipment types, quantities, job positions, and responsibilities within the compartment. Second, a link analysis diagram is drawn based on the task background and requirements, using different line types to represent link types. Then, a survey and evaluation are conducted on the usage frequency and importance of each link to determine scores for each item and calculate the score for each link. Finally, the analysis results are used to rank the links, prioritizing high-value links that meet human factors engineering requirements. Designers then complete the compartment layout design based on actual constraints.
[0004] However, traditional link analysis methods can only guide the design of cabin layouts and cannot be used for comparative analysis and quantitative evaluation of multiple cabin layout schemes. Therefore, it is urgent to build a quantitative evaluation method for the layout of ship working cabins by combining link analysis methods with ergonomic evaluation technology.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0019] like Figure 1 As shown, a method for evaluating the layout of ship work compartments based on ergonomic analysis includes the following steps: 1) Conduct a task requirements analysis to clarify the relationships between cabin equipment, positions, and personnel; The compilation of task requirements provides a basis for the assessment of the layout of ship work compartments; the compilation of task requirements transforms scattered information related to compartments (such as drawings, lists, and compilation tables) into structured data that can be used for assessment. include: 1.1) Obtain the equipment type and quantity, as well as the corresponding personnel responsible for operation; Based on the design drawings and equipment list, the equipment in the ship's work compartments is sorted out from the perspective of human-machine ergonomics to obtain the equipment types and quantities; Then, a preliminary analysis was conducted based on the frequency and importance of equipment use, and the corresponding operators for the cabin equipment were identified. 1.2) Obtain the relationships between cabin positions and personnel collaboration; Based on the design drawings and staffing schedule, the positions in the ship's work compartments are sorted out from the perspective of human-machine ergonomics, and the personnel deployment mode, personnel job responsibilities, personnel position, and communication needs and relationships between personnel are organized. 2) Construction of the link chain model; 2.1) Draw a link analysis diagram; For each work compartment, a link analysis diagram is drawn based on the results compiled in accordance with the task requirements.

The visual chain response value ranged from 1 to 4. See Table 3. Table 3 Visual Link Response Value Comparison Table
[0024] Whether something is within the field of view is determined using the following methods: Draw a diagram on the blueprint based on the relative positions of the personnel and the display equipment. Draw rays at 35° angles to the left and right of the personnel's working direction to obtain the personnel's field of vision with a vertices angle of 70°. If the center point of the display equipment screen is within the field of vision, then the visual chain is determined to be within the field of vision.
