Trust Model is an efficient way of resolving the trust problems in open networks in which trust evaluation is a key issue to be addressed in trust management. According to the design rules of trust models, the problem of the lack of dynamic adapt ability in trust evaluating, the lack of effective aggregation of trust and the lack of considerations to incentive mechanisms and so on, this paper introduced the bonus-penalty factor which shows how reliable is the direct trust of the recommend entities to the subject and evaluation reliability of the recommend entities which is used to decide whether the access object would adopt the recommendation of the recommend entities during the calculation of the recommend trust. The measurement of integrated trust solves the weight problem between direct trust and recommendatory trust by introducing balanced weight factor. Finally, we present designs of bonus-penalty function and balanced weight factor and simulations by Matlab software.
