The Human-machine Environment Evaluation System Of Ship Living Cabin

Design of living cabin is an important part in ship cabin desigin. A well-designed scheme is of great importance to improve the inhabitancy of cabin. Design evaluation is the main way to determine whether living cabin is good or not, however, since many factors affect the scheme chosen and they are hazy and incertitude, it is difficult to evaluate precisely. Therefore evaluation of traditional scheme is always subjective intuitionistic without a numeric standard. In this paper an assessment model has been achieved with numeric standard for the assessment, which gave an efficient way for the evaluating.From the aspect of design factors, the character of living cabin has been analyzed and the delaminated indices of living cabin compostive assessment system have been put forward.By analyzing and comparing some multi-criteria decision method, a synthetic evaluation method is put forward. This method combines TOPSIS with grey relation prejection method and gives the evaluation results by accounting synthetic relational projection which is based on dealing with qualitative indices by fuzzy whitenization.According to previous theories, evaluation software has been developed which is based on Microsoft Visual Studio 6.0 platform. And the above theories and method are well tested by applying the proposed software to the comprehensive evaluation research on the double room in a passenger ship, and achieved the quantified results.The evaluation indices of living cabin were founded; an efficient decision-making model was carried out, an applied software was exploited. What all these supplied references to the evaluation of the habitability in living cabin.
