System Integration Method Based on a Public-Private Hybrid Deployment Model: Strategic Simulation Modelling of Red Sea Civilian Maritime Security Forces

The purpose of this study is to construct and validate a strategic simulation modelling framework for civil maritime security forces in the Red Sea region, in response to the dual challenges of multiple threats to international shipping and insufficient official escort resources.Based on the theory of Public-Private Mixed Deployment Model (PPM), this paper combines the System Modeling Language (SysML) and process optimisation algorithms to construct a modular security task chain, a response path logic diagram and a simulation iteration flowchart, and forms a multi-dimensional decision support system covering area assessment, response efficiency analysis and cost control.Comparative experiments are conducted through three scenarios (official independent escort, civilian coordinated intervention, and modular deployment in the Red Sea), and the results show that the "modular + coordinated response" model is better than the traditional deployment in terms of improving threat coverage, response speed and mission resilience.Further analyses also point to the tactical complementarity of civilian security forces in specific regions (e.g., the Gulf of Guinea).It is concluded that civilian forces can be an important extension of national convoy operations, subject to regulatory compliance and technical support.The study provides a systematic modelling approach and policy reference for future maritime security deployments in the Gulf of Aden-Red Sea-Suez corridor, as well as a new simulation paradigm for the collaboration of multiple actors in the global shipping security governance system.
