船舶主尺度技术经济分析的模糊数学规划方法

Application of Fuzzy Mathematical Programming for Techno-economical Analysis of Ship's Main Dimensions

本文运用模糊数学的理论和方法建立了运输船舶主尺度技术经济分析的模糊优化模型，对经典数学规划中分明的约束边界作了模糊化处理，以便反映客观世界普遍存在的模糊性．通过秦皇岛港一温州电厂航线煤运船舶主尺度模糊优化的实例计算结果表明，该方法是进一步提高运输船舶主尺度优化设计质量的新途径．

In this paper a fuzzy mathematical programming model for techno-economical analysis of ship's main dimensions is developed on the basis of the fuzzy sets theory. With the adoption of the membership functions of oblique linear type and peak type, the crisp boundary in the classic model is converted into fuzzy constraints, which is practically valuable for ship designers. The main dimensions of a collier along the route between Port Qinhuangdao and Wenzhou Power Station are optimized by using this method. The results obtained show that this method presents a new approach to the optimal design of ship's particulars.
