    ---
    A logistics specialist for Wiethoff Inc. must distribute cases of parts from 3 factories to 3 assembly plants. The monthly supplies and demands, along with the per-case transportation costs are:

    Destination Assembly Plant
    1 2 3 Supply
    Source A 5 9 16 200
    Factory B 1 2 6 400
    C 2 8 7 200
    Demand 120 620 60

    Hints:
    LP for the above model is
    Decision variables:
    xa1 be the quantity shipped from factory A to assembly plant 1. Similarly we have
    xa2, xa3, xb1, xb2, xb3, xc1, xc2, and xc3

    Objective function:
    Min: 5 xa1+ 9xa2+ 16xa3+1 xb1+2xb2+6xb3+2xc1+8xc2+7xc3
    As it is the case of balanced transportation problem, constraints are
    Supply availability
    xa1+ xa2+xa3=200
    xb1+xb2+xb3=400
    xc1+xc2+xc3=200

    Demand requirements
    xa1+ xb1+ ...
