Abstract

The annual maintenance project is an important measure to further advance the maintenance reform of ship equipment in a certain direction. It is a powerful grasp of strengthening the control of the equipment technology status of the ship. At present, the progress control of the annual maintenance project is still in the traditional management and control mode, and the maintenance cycle is longer. In order to improve the traditional schedule control method, this article introduced the uncertain factor coefficient, process location coefficient, time elasticity coefficient, and resource utilization on the basis of key chain technology theory, and obtained the calculation method of the project buffer. A model control model of annual maintenance projects based on key chain technology is constructed. This provides a certain basis for the subsequent annual maintenance work.
