The Research On Security Resource Allocation Of Marine Fire On System Stability

With the sustained and rapid growth of marine economy, the risk of marine fire is increasing. Casualties, property damage caused by marine fire have caused worldwide concern. However, the characteristics of marine fire and the complexity of resource requirement put forward a higher requirement for the security resource allocation of marine fire. Under multiple constraints such as time and materials, how to allocate the security resource rationally is the key issue addressed by this paper.In the first part of this paper, the definition, characteristics, classification and grading of marine fire are described. The concept of "security resource of marine fire" is then put forward, considering it as a integration of safety defense resource and accident rescue resource. And thus innovatively constructs a security resource allocation system of marine fire comprising of prevention stage, self-adaption stage and external rescue stage. The second part is a systematic analysis of the system’s structure, Especially, the energy transfer process and the feedback process are analyzed in detail. Drawing system control theory, the third part uses mathematical language to explain the internal structure of the system, considering the system as a linear time-invariant feedback system. And then the transfer function and state space expression of the system are constructed, the performance of controllability, observability and stability are analyzed. According to the situation that a single stage’s resource cannot meet the demand, a security resource allocation model for marine fire is developed with the objective of completing the extinguishing task within the allotted time. The model solves the resource allocation by identifying the accident energy consumption of each stage. Finally, the solvability of the model is illustrated on a simulation experiment.
