Assessment of Large Vessel Support Capability Based on Comprehensive Weighting Model

As a typical representative of complex electromechanical systems, only through the timely and effective equipment support activities can large vessel play its proper mission capabilities and ensure the successful completion of diversified missions. With the changing types and requirements of the large vessel to complete the missions, the difficulty of assessing the large vessel support capability also increases significantly. In this paper, a three-level assessment indicator system for the large vessel support capability is established based on the influencing factors of the equipment support, and the main indicators and their sub-indicators are selected according to the four aspects of the support capability: use and management, support command, redeployment support and technology support. Then, based on the assessment indicator system of the large vessel support capability, a weighting method for the assessment indicators is proposed combined with AHP and entropy method. A subjective weight model of the indicators is established based on AHP, and an objective weight model of the indicator is established based on entropy method. A comprehensive weight model is established based on the subjective and objective weights for assessing the large vessel support capability. Finally, taking a certain type vessel as an example, the results of the numerical analysis show that the assessment indicator system of the large vessel support capability and the weighting method are effective and feasible, and the conclusions of the assessment and analysis can provide an engineering decision-making basis for improving the large vessel support capability.
