船舶动力系统能耗控制合理性评价对降低航运能源消耗具有重要意义。本文以10万吨级散货船柴油机动力系统为研究对象，针对传统能耗评价算法主观权重占比过高、动态工况适配性差的缺陷，设计改进型模糊综合评价算法，通过层次分析法与熵权法构建主客观融合权重，结合船舶动态工况特征优化自适应梯形隶属度函数，实现能耗指标合理性的精准量化。基于28组实际营运数据开展实例分析，结果表明，本文算法有效提升了动态工况下的评价精准度与稳定性，明确了不同工况下能耗指标的合理性差异及核心优化环节，研究成果可以为商用船舶动力系统能耗优化提供量化依据与技术支撑。
The rationality evaluation of energy consumption control for ship power systems is of great significance for reducing energy consumption in the shipping industry. Taking the diesel engine power system of a 100,000 DWT bulk carrier as the research object, this paper designs an improved fuzzy comprehensive evaluation method to address the shortcomings of excessive subjective weight proportion and poor adaptability to dynamic operating conditions in traditional energy consumption evaluation algorithms. Specifically, subjective-objective combined weights are constructed via the analytic hierarchy process (AHP) and entropy weight method, and the adaptive trapezoidal membership function is optimized by integrating the characteristics of ship dynamic operating conditions, thus realizing the accurate quantification of the rationality of energy consumption indicators. Case analysis is carried out based on 28 sets of actual operation data. The results show that the proposed algorithm effectively improves the evaluation accuracy and stability under dynamic operating conditions, clarifies the rationality differences of energy consumption indicators under different operating conditions and identifies the core optimization links. The research results provide quantitative basis and technical support for the energy consumption optimization of commercial ship power systems.
