Starting with the overall design of safe access control system,the article generalizes a kind of access control model into a general framemodel,and introduces its working principle,authorization policy,security authentication manage ment and basic function component of realization.

It extracts function component based on operation flow from requirement specification, maps and recomposes test scripts, generates test case with input data.

The functional structure framework of product quality information management is established,based on using cases modeling of unified modeling language(UML) and functional component bases technology.

To deal with the influencing factors such as production cost supported by networked collaborative manufacturing,product function component & process method,and task manufacturing cycle of mechanical product,from macro viewpoint,the issue of task granularity planning of product manu.

In order to solve such problems as low efficienc y, excessive repeated work, poor universality and interchangeability in the design of VI software, a new developing method of test functional component oriented to virtual test is put forward, namely a series of reusable virtual test oriented test functional components are developed via adopting mature component technology.
