Is it standard maxflow problem?
May be it is 4-types of products flow?

AC  without times using.
LP problem for 4-component flow
with help of simplex method(my smpmeth is above struct{__int64 intpart;__int64 num;__int64 denum;char sign;};)
By the way, very good question:
why maxflow algo doesn't work.

Maxflow algo doesn't work because it uses ways like M-1-2-3-Y or M-4-5-6-Y, that are not available.
