Research on the Comprehensive Evaluation of Environmental Comfort in Deep-Sea Confined Space Based on Entropy Weight Method

Abstract

AbstractIn order to provide a reference for improving the environment of deep-sea confined space and improving the comfort of the space environment, this study constructs a deep-sea confined space from four aspects: heat and ventilation environment, light environment, sound and vibration environment and comprehensive design according to the characteristics of deep-sea confined space environment. The environmental comfort evaluation index system has established a comprehensive index evaluation method, including index standardization, index weight determination based on entropy weight method, index comprehensive calculation and classification. A questionnaire survey was used to investigate and comprehensively evaluate the environmental comfort of a deep-sea confined space manipulation area (Area A), a residential area (Area B) and a dining area (Area C). The environmental comfort evaluation index system of deep-sea confined spaces is constructed from twelve dimensions, including temperature, ventilation, odor, humidity, noise, vibration, swing, lighting, color matching, space design, human factor design, and floor comfort. The research results put forward corresponding improvement suggestions for the environmental comfort of a certain deep-sea confined space manipulation area (Area A), living (B area) and dining area (C area).KeywordsEntropy weight methodConfined spaceEnvironmental comfortComprehensive evaluation
