%X The development of internetware is a process of component composition in internet environment, so the traditional reliability analysis technology can not be directly applied to internetware. This paper defined the model and physical model of internetware, and analyzed the measure methods about five type of component composition structure on the basis of formal definition of reliability. Put forward an approach of internetware optimization meeting the reliability expectation. In this approach, transformed complex internetware into serial composition structure, and proposed an improved ant colony algorithm to achieve the mapping of model and physical model of internetware. This algorithm employed the reliability expectation threshold of model and physical model to filter invalid branch, and selected better path based on the reliability expectation of internetware. Finally, the experiment proved that this method is feasible and effective to solve reliability optimization problem of internetware in open environment, and has better performance than traditional method.
