Mixed Integer Model In the mixed integer formulation, presented in Table VII, the variables which indicate the facilities to be built, X,, remain zero-one integers as before, whereas the variables Yi; now represent the amount of power to be transmitted from each plant alternative to each load center, and are no longer zero-one integers but continuous variables. In other words, instead of simply indicating whether or not any power is transmitted from plant alternative i to load center j, Y in the mixed integer ij formulation represents exactly how much power is assigned to each plantload center link in the system. The other mathematical symbols are defined in the same way as in Section 2.3 and Appendix A. A solution of the mixed integer formulation using the implicit enumeration technique would supply answers to much larger problems than those solved by the zero-one integer model previously described. Work on this type of computer algorithm is the next developmental step in this field. |
