Abstract

The invention relates to a fault mode-based establishment method for a maintenance support simulation system for an equipment basic level. The establishment method comprises the following steps of: S1, establishing a fault simulation model for a basic level support object; S2, establishing a state simulation flow for the basic level support object; S3, establishing a maintenance activity simulation flow for the basic level; S4, establishing a support resource service simulation flow; S5, simulating and outputting a supportability index evaluation result. The method is capable of realizing a simulation evaluation on various supportability indexes, and solving the problems of divorce between the prior art and an actual development process for equipment, and low index evaluation credibility.

Description

technical field [0001] The invention relates to a method for building a maintenance support simulation system, in particular to a method for building a maintenance support simulation system at the basic level of equipment based on failure modes. Background technique [0002] In the process of equipment development, it is necessary to simultaneously carry out support design work, develop a support system, and evaluate relevant indicators through test verification methods. Establishing a maintenance support simulation system to simulate various uncertain factors in the process of equipment maintenance support through computer models has become an important means for early verification and evaluation of support design, especially grass-roots maintenance support design. In the existing maintenance support simulation system, more attention is paid to the description of the simulation process by using various generalized mathematical models such as Petri networks, which is out of ...
