A sequential linear programming approach to solve mixed integer programming problems (Q1117139)

The authors consider the problem of the optimal operation of pumps in a large water supply system under time-of-use electricity rates. They formulate the problem as one of mixed integer programming and propose an iterative solution scheme that consists of a sequential application of the linear programming solution technique. The scheme was successfully applied to the Inglewood Water Supply System. But the authors note that the algorithm does not work so well in the case of academic problems.
