A conditional adaptation can be provided by a rule engine invoking rules at appropriate situations, based on a user model.
一个可以依据用户模型在适当情况下调用规则的规则引擎就可以实现这样的条件适应。

The WS-BPEL representation of the process (Figure 2), is similar to the business model in that there are steps which are wired together, along with conditional branching logic.
