MapInfo 有没有和ArcGIS Network Analyst类似的功能？

在用MapInfo 7.8，想做一个图显示根据路网的Service Area，和下面的图一样

The green points represent warehouses in various cities, and the polygons represent their market areas, which are divided into three rings. The surrounding green polygons can be reached by trucks within two hours; orange, within four hours; and red, within six hours.

这个图是在ArcGIS上面用Network Analyst功能实现的，就想知道MapInfo有没有类似的功能，能做一个这样的图。
