OPTIMISATION OF STRATEGIC PLANNING FOR COPPER/NICKEL MINING AND METALLURGICAL COMPLEXES

OBJECTIVE OF THE MODEL
To enable Management to generate MAXIMUM NPV plans for COPPER/NICKEL MINING AND METALLURGICAL COMPLEXES

SUMMARY OF "COPPER 2003" PAPER Santiago Chile

The generic description of the holistic approach to strategic planning within a number of linked Cu/Ni integrated mining and metallurgical complexes, is based on an actual development that was undertaken for Anglo American Corporation of South Africa in the mid-nineties. Model results indicated clear strategies resulting in the more than doubling of the group NPV compared to the existing planning. Worth-while Southern African opportunities for pooling Cu/Ni resources, including the shutting down of production units and the expansion of others, were identified and after presentations to the Boards of the companies as well as to committees of some of the regional Governments, the strategic planning of the Companies were adjusted accordingly.

The approach offered by Linear, Mixed Integer, and Recursive Linear Programming techniques, is one of optimum solutions with associated techno-economic sensitivities, subject to the constraints applied. As such, this approach is considered to be the only method to exploit optimally all the resources at the disposal of a company, consequently, to empower that company to remain at the competitive edge of the industry in which it is involved.
