In this paper, a M–H method-based decision support system (MHDSS) which could evaluate survivability and aid real-time decision in shipboard flooding accident is presented. It relies on certain reasoning logic to select available counter-flooding tanks (CFTs) combination to provide swift and effective decision-making support for shipboard personnel on warship. In order to achieve an optimal response to a flooding accident, the M–H method firstly confirms the feasible region of CFTs, within the region to generate the scheme accurately according to established model in MHDSS. To evaluate the feasible scheme acquired, tilt angle is established as the decision criterion. During the process of searching for the feasible scheme, the method generates a scheme of single tank operation for one iterative process, and the final output is composed of all the scheme of single tank operation by means of linear superposition until terminating condition is encountered. The developed system, which offers remarkable advantage over the originally investigated ones, mainly focuses on real-time decision aid for damage control in case of emergency. The computational results validate the effectiveness of the M–H method, as well as the proposed criterion is applicable to evaluate the scheme. ► The M–H method relies on certain reasoning logic to select available CFTs combination. ► The M–H method firstly confirms the feasible region of CFTs, then generate the scheme accurately. ► The method generates a scheme of single tank operation for one iterative process. ► The final output is composed of all the scheme of single tank operation by linear superposition.
