Research on Equipment Maintenance Time Management based on Risk Evaluation

Project time management is an important part of project management of returning to factory for maintenance. In this paper, planning evaluation technology (PERT) is used to manage the time of the project of warship weapon equipment maintenance, and the fuzzy comprehensive evaluation method (FIE) is used for the uncertain factor’s risk evaluation that affect the schedule of the project. It is applied to a certain grade repair example of a specific type of radar equipment, and a more scientific and reasonable project duration is obtained, which provides a reference for the project time management of the warship weapon equipment grade repair project.
