Hi Xiaoyu,

Hope you liked my design, I'm just looking for some feedback on <a href="http://www.designcrowd.com/design.aspx?designId=207773">designId=207773</a>

I was away for a couple of days. Now seeing all your designs. Some of them I really like. 

@George, "agents" in this context can be seen as "software with intelligence", who act as representative/assistance of real-world object - aircraft, airlines, airport authority, ground handling service provider. Agents can interact with each other much faster than human being. And with increased interaction,  they can negotiate better plans/schedules. 

@Chris, Your artistic sketch is something i am looking for. The background color is not one of my favorite tho. If you have time, i would appreciate you can submit a full version. Thanks.

Best regards,

Xiaoyu
