On the basis of knowing the maintenace items and basic maintenance technological process of thermal pewer equipments in power plants

taking the realization of planned arrangement in maintenance as the purpose

a maintenance management framwork

in which corresponding automatic ajustment can be made according to the variation of actual progress schedule in the project

has been put forward

and the key algorithms in management process of the progress schedule being thoroughly analysed and studied.Finally

taking Visual C++6.0 as basic development means

and comprehensively using design methods

such as data-base

and systematic fundamental class bank etc.

a maintenance management system of the steam turbine has been developed.
