Abstract: BDI is one of the models in Agent Systems. Currently, most of BDI agents` researches are focused on the ability for agents to dynamically select plans to achieve a goal. There are fewer discussions on Intention Scheduling, the order in which the selected plans are executed. Agents must adapt to dynamical and unpredictable changes. Without a proper scheduling scheme, an agent may repeat unnecessary works, waste valuable resource or even fail the users` expect altogether. In this study, we present an effective intention-scheduling scheme in BDI reasoning process, to make BDI agents more efficient and suitable for execution.
