Hi there,
I am looking for a solution method to solve a linear programming
problem having the form:
Minimize c'x + d'y + e'z ( ' denotes transpose )
x,y,z
P1
subject to Ax + By + Cz <= b
x >=0 , y >=0, z >= 0
where x, y, and z are vectors of design variables of dimensions
nx, ny, and nz, respectively, and c, d, and e the corresponding
cost vectors. Since nx, ny, nz, and the number of
inequality constraints are large, I'm interested in a solution method
which decomposes problem P1 into small subproblems for
x, y, and z separately. However, they are interrelated through a master
problem.
Does anyone run into this kind of problems or have any ideas about such
solution technique?
Thanks in advance.
