A timetabling problem is formulated as a large integer linear programming problem in 0-1 variables. A solution method based on Lagrangean relaxation coupled with subgradient optimization is presented.

Abstract: This paper considers a dynamic spectrum allocation (DSA) for efficient distribution of the spectrum resource by allocating the spectrum to be responsive to demand variations. In this DSA ...

Abstract: This paper investigates the load transfer function of the distribution automation project to be implemented in Taipower distribution system. During the summer peak season, the main ...
