ABSTRACT In order to improve the emergency handling ability of Marine rescue in the Arctic, this paper proposes to use TOPSIS (Technique for order preference by similarity to ideal solution) and the Weighted scoring method, respectively, to identify the dispatching rank of Marine rescue forces. By comparing the two methods of dispatch sorting result, the better method is identified. Firstly, according to the environmental characteristics of the Arctic, the evaluation indexes of the dispatching rescue force is selected, and the weight coefficient of the evaluation indexes is determined comprehensively by the AHP (Analytic hierarchy process) and the Entropy weight method; Then, a typical accident situation in the Arctic Sea is set up, and the Weighted scoring method and TOPSIS are used to rank maritime rescue forces stationed in Murmansk respectively. Finally, taking the rank results obtained by the Weighted scoring method as a reference, the rank results obtained by TOPSIS are compared with it. It is concluded that the rescue forces dispatch rank obtained by TOPSIS is more reasonable, which shows that TOPSIS can effectively be used to identify the selection of rescue forces and provide valuable advice to the Arctic Maritime authorities on their search and rescue operations in the Arctic Sea.
INTRODUCTION The accelerated melting of Arctic Sea ice is making Arctic shipping lanes more open and polar operations are growing rapidly (Rottem, 2013). In the Arctic region, the environment is cold and harsh, and maritime accidents on ships seriously affect the safety of people on board. Therefore, it is urgent to enhance effective and quick maritime rescue (James and David, 2019). In order to ensure safe operation of polar shipping, scientific research, resource development and other activities, we should improve the efficiency of rescue and support operations, and minimize the risk of accidents (Bercha, 2006). It is necessary to carry out research on polar rescue forces dispatch, so as to achieve the optimal rescue effect in the shortest time.
