(1) Find ALL the flows (bottom left) (you did last day) (2) find all the u;'s and v;'s (3) find the two remaining reduced costs (x,y) D1 D2 D3 supply 3 0 4 10 6 X S1 B IN 120 5 3 10 5 10 0 IN IB dB 120 U2 = e demand 80 70 90 V v1 = f v2=g V3 = h u a u1 = 0 S2 the values of the requested variables are (1) a is bis cis and dis (2) in the order you should find them shadow prices are: fis and gis then e is and finally h is (3) and thus the reduced costs are x is and y is
