Research On Optimization Of Emergency Materials Reserve Depot Layout For Marine Major Perils

With the rapid growth of world marine economy, the risk of marine perils is increasing. Casualties, property damage and pollution of the environment caused by the marine perils have caused widespread concern around the world. Yet, the characteristics of marine perils and the complexity of rescue environment put forward a higher requirement for the prevention, control and rescue. Especially for marine major perils, how to reasonably layout the emergency materials reserve depot, so as to supply timely and effective resource to the accident spot after the accident and reduce accident losses is the key issue addressed by this paper.In the first part of this paper, the characteristics of marine perils, grading response procedure and the security of rescue resources are described, and thus construct a multi-layer emergency materials reserve depot layout network comprising of the accident layer, shore-based emergency materials reserve depot collecting layer and land-based emergency materials reserve depot supply layer. The second part is a systematic analysis of the problem of emergency materials reserve depot layout. Especially, from the aspects of waters risk distribution, emergency response time, emergency materials demand, emergency materials owned by ship, the influencing factors are analyzed in detail, and this is the fundamental to the modeling analysis of the following chapter. Finally the emergency materials reserve depot layout model is established based on the double programing, which reasonably locate and allocate between shore-based and land-based emergency materials reserve depots, also make the lowest cost of the rescue system. Then particle swarm optimization (pso) algorithm is introduced to solve the model, and a concrete example is set to verify the rationality and validity of the method.
