Abstract:In order to find out the "Interval attributes" that affect the implementation of large-scale instrument sharing service in the process of large-scale instrument sharing service, this paper analyzes large-scale instrument ownership based on the shared service record data of Yunnan large-scale scientific instrument open sharing management platform, using such indicators as connection degree, connection weight and service frequency of complex network. The attributes matrix of service object of large-scale instrument sharing organization is obtained by interval demand, directional service demand and external service demand of the organization. Based on the attributes matrix of service objects, the demand components of instrument sharing services provided by large-scale instrument sharing service organizations with different functions of market demand, education, scientific research and public service are analyzed quantitatively, and the different interval attributes of instrument owners are obtained. This result can provides basis and reference for formulating the sharing management system and performance evaluation indicators for large-scale scientific instruments.
