In order to maximize the efficiency of large-scale instruments and solve the problems caused by the large number of instruments,limited warehouse,early instrument production,and multiple multi-channel collection box-type instruments in the harbor and waterway industry,a set of 7S management mode with harbor and waterway professional characteristics,which can promote the sharing of large-scale instrument resources and stimulate instrument efficiency,has been gradually established after 5 years of continuous exploration and 3 years of application practice.This mode emphasizes that the management of large-scale instruments should be carried out step by step.First,the standardized management of instruments should be realized,the instrument information base should be established,then the intelligent and innovative management should be carried out,and the existing advanced experimental technology should be adopted,large-scale instruments to achieve open sharing,upgrading and secondary development.Practice has proved that the management mode has greatly improved the efficiency of instrument use,facilitated the use of teachers and students,and played a demonstrative and leading role throughout the whole school.
