Research Of Ship Cabin Layout Design Considering Regional Compound Environment

The improvement of ship 's habitability makes people more aware of the importance of cabin environment.However the current research focuses on the influence of single cabin environment or an environmental factor on the comfort.There has been a lack of integrated research of regional compound environment.Different cabin layout schemes will correspond to different environmental values,and the environmental factors shall be taken into account in the design stage,which is expected to minimize the negative impact between different cabin environments,and obtain a better comprehensive performance layout scheme to improve the living comfort.At the same time,excellent basic environment can theoretically reduce the workload of outfitting and the cost of dressing board so as to improve economic performance.Because there are many factors in the compound environment and the influence principles are complex,it is difficult to directly take the environment function as one of the objectives of the cabin layout.Therefore this paper proposes a research method combining the intelligent cabin layout with the regional compound environment evaluation.Firstly,on the basis of the living area cabins as the research object,the mathematical model is established.Then it takes the adjacent requirements of the cabin and the personnel circulation performance as the solving objects,and uses the NSGA-? algorithm for calculation to obtain feasible arrangement schemes.Next it analyzes the characteristics of cabin environmental factors,summarizes the influence principle and mathematical expressions to provide theoretical support for the calculation of environmental values.Because there are many fuzziness in the evaluation process of cabin environment,the traditional mathematical method doesn't work,the fuzzy comprehensive evaluation method is chosen to quantify and mathematize the fuzzy problem.In order to ensure the scientific nature and objectivity of the evaluation results,the determination of membership functions and weights is essential.This paper analyzes the specification requirement and the experimental data,and according to the regularity of changes in environmental factors comfort establishes the membership function by assigned method,and uses yaahp software to calculate the cabin environment factor weight.On the basis of this,the initial value of the cabin environment is constructed,the corresponding environmental value of each scheme is calculated,the final evaluation result is obtained according to the evaluation procedure,and the optimal scheme is analyzed.The research of this paper proves that the intelligent cabin layout design and environment comprehensive evaluation can form a complete cabin layout design method.According to this method,a good layout scheme of function-related,personnel circulation and comprehensive environment can be obtained in the design stage,which provides a new idea for the study of the cabin layout design in ship living area.
