Abstract: Reliability activities are throughout the life cycle of products. Based on the ideas of reliability engineering and analysis of reliability testing of notebook，a new plan of reliability testing of notebook is put forward. In the plan, the testing is designed from the field experiments, and the factor of testing is recorded by certain sensors. The test platform is built from the test items and the test requirements. The test platform has the flexible structure and intelligent control function. The test work requires the management of reliability which is aimed to form the test specification.

Abstract: This paper chose multi-index to provide a comprehensive evaluation model to evaluate the use reliability of CNC machine tools as a single assessment indicator is biased. As the number of evaluation factors is huge and it is difficult to get the exact values, a fuzzy theory is applied. Reliability mathematical model and maintainability mathematical model were established based on failure data selected from filed test and calculated the estimation values of reliability indexes. Subsequently, a fuzzy comprehensive evaluation mathematical model of CNC machine tools was constructed which combined fuzzy with comprehensive evaluation theory. Using this model could evaluate reliability level of CNC machine tools accurately and integrative.
