ABSTRACT
As the development of photoelectric technology, a larger number of the high-tech photoelectric equipment was put into the market and paid more attention by customers. The function of the photoelectric equipment was much more integrated and complicated. In order to meet the requirement of customers in support, it’s necessary to bring the manufacturers’ technical service level and skill to keep the equipment in a steady, available condition. So, customers often had signed a contract with contractors in program warranty. Within the warranty, customers could perceive the potential failure mode in the photoelectric equipment and carry out the preventable work to decrease the possibility of the failure by the contractor. The work which could make the best use of the equipment age and reduce the cost of the maintenance task, had practical implications.
