110 Ellaia et al.4. Results and Concluding RemarksThe current trend in global optimization research is the combination of techniques obtainedfrom diverse penalty function methods, in order to develop more reduced gradientmethod. The RPRGA follows the above concept, by trying nonlinear programming problemof model formulation.In Morocco, the ONEP has spent in 2003 about 290 millions of DH as bill of energy tosatisfy needs of people to drinking water,this cost is always getting higher. To limit theeffect of this increasing on water production, many projects of optimization waere donefor example used commercial programs LINGO see Ref. [2] these solutions are takeninitial value in Fortran code of RPRGA for numerical applications in order to give theresults more optimal see Ref. [4].5. References[1] A.
