ABSTRACT
The main object of this paper is to analyze the reliability of the complex mechanical system on the base of the Lambda-Tau (L-T) methodology and fuzzy math. In order to quantify the uncertain of the system reliability more close, this paper utilizes the improved artificial bee colony algorithm to optimize the L-T methodology. The obstacle of the complex structure will be conquered with the help of the petri nets approach. An example of a satellite antenna’ drive system is taken account to demonstrate this method. The system reliability model of the drive system is built by the petri net and the reliability behavior is analyzed with the IABCBLT proposed in this paper. At last, the results obtained from GABLT, PSOBLT and traditional ABCBLT are compared and it can be conducted that that the method proposed by this paper could get more precise results in uncertain mathematic.
