The Wonder Waste disposal company has 5 truckloads of nuclear waste and 5 truckloads of hazardous chemical wastes that must be moved from its current cleanup site to nuclear and chemical disposal facilities, respectively. The following table shows that many of the available roads are restricted for one or the other type of waste.

Road From To Nuclear OK Chemical OK Site NDisp Yes No Site CDisp Yes Yes Site Inter No Yes NDisp CDisp No Yes CDisp Inter Yes No Inter NDisp Yes Yes Also, Wonder Waste wants to distribute any risk by allowing no more than half the 10 total truckloads on any road. One particular road, the link from crossing Inter to the nuclear disposal facility, is especially well suited to hazardous transfer because it runs through very remote areas. Wonder Waste seeks a feasible shipping plan that maximizes the use of that road.
