Cost-effective sulphur emission reduction under uncertainty

Article Abstract:

The problem of reducing SO2 emissions in Europe is formalized and a specialized solution methodology is developed which is applied to actual situations. By utilizing a mean-variance model, the non-deterministic problem with small data samples, was properly treated. The numerical method which used a quadratic version of an interior point method was found to be efficient and robust. Using this method, the computational methods such as symbolic Cholesky factorization of sparse matrices, splitting dense columns and minimum degree ordering were successfully implemented.
