Mining corporate portfolio optimization model with company’s operational performance level and international risk


The mineral industry has encountered severe price turbulence in the recent years. A new portfolio management strategy will help to actively deal with this turbulence, corporate mining organizations need to improve their decision-making processes associated with capital allocation to new proposed projects. The proposed approach will help mining corporates to improve their capital allocation strategies to new projects in such a way as to consider operational performance in the prioritization of business-related spending on capital projects. The problem is formulated as the minimization of the risk at the desired return under constraints of operational performance requirement of the project’s initiators product group. This optimization model is solved using MATLAB. The results show that, on top of the NPV criteria, the more you diversify the portfolio, the more you potentially increase the corporate portfolio return and the more you slightly increase the risk for correlated projects. These results also show that as the performance of the product group increases, the number of approved projects at the corporate level also increases.
