Abstract: To evaluate the Antarctic research station network efficiency under different site layouts, an optimized network efficiency evaluation method was proposed based on local properties. The relative importance of points and edges was evaluated, based on Analytic Hierarchy Process (AHP) and Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS), to represent the local properties of the network. The relative importance was substituted in the modified network efficiency model to obtain the operational efficiency of the network. This method was used to analyze the operational efficiency of China’s, the United States’ and Australia’s Antarctic research station networks. This method is suitable for efficiency evaluations of different networks, which can provide a reference for site selection or overall layout adjustments of new Antarctic research stations in the future.

Key words: network efficiency, local properties, Antarctic research station, Analytic Hierarchy Process, Technique for Order Preference by Similarity to an Ideal Solution
