Wherein the computer device may configure the start and end time ratios of each reliability work item within a phase (e.g., a discussion phase, a project phase, an engineering development and finalization phase, a production and use phase, etc.) in the reliability work item matrix and then calculate the start and end times of the reliability work item based on the start and end time ratios. For example, the actual start time calculation formula for the reliability work item Ti within phase Pj may be: sti= Ptj (EPi-SPI), the actual end time can be calculated as: eti= Ptj ×epi, where Ptj can represent the duration of the phase Pj.

Further, the computer device may automatically generate an initial work plan package in batch according to the configured reliability work item matrix, where the initial work plan package may include a reliability work plan of each product level and each stage of the equipment to be analyzed, where the work plan is a carrier of a work task, and when the work plan passes through approval, implementation of the work task may be started.
