Availability for repairable redundancy system with the restriction of spare parts

摘要

The availability for repairable redundancy system with the restriction of spare parts is researched. In order to solve this problem, first, the elementary theory of availability is expatiated. Then the calculation model is constructed, which has consider the unit' connection style and the restriction of spare parts. Basing on the analyzing mentioned above, the method of how to calculate the availability is given. Experiments show that the model works well and this result establishes good base for further research in relative problems.
