Research And Analysis Of Yunnan Tietong Comprehensive Operation And Maintenance Work Order Management System

There are many workform systems in Yunnan Tietong, and each independent operation. It needs to log in different systems for processing, the use of cumbersome, low efficiency, and not easy to unify the analysis.
