基于熵权TOPSIS模型的海岸线登陆点评估
Evaluation of amphibious operation landing sites based on the Entropy-weighted TOPSIS Model
摘要
Abstract
The evaluation of landing sites is a critical component of maritime rescue,disaster emergency response,and material delivery operations,influenced by various factors such as coastline topography,seabed composition,and geographical and geological environments.Existing evaluation methods typically rely on a limited set of influencing factors(e.g.,coastline topography,seabed composition,vegetation cover)and qualitative manual rule-based approaches,which suffer from few-factor,experience-based limitations,failing to meet the needs for quick,safe,flexible,and cost-effective landings.To address these issues,this paper proposes an evaluation model based on the entropy-weighted Technique for Order Preference by Similarity to an Ideal Solution(TOPSIS),which comprehensively considers hydrological,coastal geographical,and geological attributes.First,an evaluation index system is established,encompassing four primary categories of indicators—maritime factors,transportation factors,geographical factors,and geological elements—along with their detailed sub-indicators.Then,weights are assigned to each factor using the entropy weighting method,and the TOPSIS model is used to calculate the relative closeness of each landing site to assess landing suitability.Finally,the evaluation results are filtered based on the landing width requirements of standard landing craft,producing the final landing evaluation map.A typical coastline is selected as a case study for analysis,and the results show that transportation and geological factors are critical indicators affecting landing site evaluations,which were often overlooked in previous studies.The entropy-weighted TOPSIS model identifies six safe,flexible,and economical landing points along the chosen coastline.关键词
