Consider the following problem with two locations and three machines. Suppose that the costs of transporting a unit load from location j to location r are given in the following table:

To location A B From A 6 location B 9 The average numbers of trips required from machine i to machine k per hour are To machine 1 2 3 1 0 3 1 From 2 0 0 3 machine 3 0 4 0 Relocation costs are ignored. Write out the complete quadratic assignment formulation for this location problem.
