Ergonomic evaluation of DSV cockpit console based on comprehensive decision making method

Abstract

In order to guarantee the effectiveness of operation, ergonomic evaluation of deep-sea submersible vehicle (DSV) cockpit console has been widely researched and developed. However, due to the characteristics of information integration on the console, and the way of information interaction becomes more and more complicated currently. The existing evaluation method mostly based on partial attributes result in unilateral issue. Considering that ergonomic evaluation processes of DSV cockpit console involves multiple decisions for multifarious attributes under vague conditions, we established an evaluation system with an improved Delphi method based on experts’ opinions and introduce a comprehensive ergonomic evaluation model by using the two-tuple weighted averaging operator (T-WA) and extended Vlsekriterijumska Optimizacijia I Kompromisno Resenje(VIKOR). Finally, an illustrated example on DSV cockpit console evaluation was performed, and the evaluation result was compared with other four typical evaluation method, it indicates the effectiveness and feasibility of the proposed method.
