摘要
船型经济论证是一项复杂的系统工程,涉及到多个指标和因素。针对多准则、多目标的船型经济论证决策问题,以灰色理论为基础,构建了基于灰色关联的船型决策经济论证方法和决策模型,并结合实际进行实证研究。实例计算分析结果表明,该方法在一定程度上考虑了船型方案各指标间的关联性,同时克服了船型决策过程中的主观臆断性,决策计算相对简单,方法与模型合理、实用。
Economic evaluation of the ship form is a complicated systematic project, which involves many indexes and factors. For the multi-criteria and multi-objective decision-making problem of economic evaluation of the ship form, a reasoning method and decision making model of economic evaluation of the ship form based on gray relational anal- ysis are set up. The verification of the model is carried out with practical cases. Calculation results of practical cases show that the method reflects the correlation of the all indexes of the ship form to certain extent; subjectivity in the process of decision making concerning the ship form is eliminated and the calculation for decision making is relatively simple, so the method and models are rational and practical.
