Heuristic algorithm for planning problem of fishing port sheltered from typhoon

The rational planning of fishing port sheltered from typhoon plays an important role in reducing fishery loss from typhoon.The mathematic model of fishing port planning in the southeastern coastal region is built.The complexity of the model is analyzed.Following the principle of "Fishing vessles should shelter from typhoon in the nearest fishing port",the paper puts forward a heuristic algorithm,which firstly considers the shortest time to return fishing port.The actual data of fishing ports and vessels in the southeast region are utilized in calculation and the survey data are used to envaluate computing result of heuristic algorithm.The result shows that the heuristic algorithm carries accepable accuracy.
