South Africa is a major mining country that hosts some of the world's largest mining companies and has a comparative advantage in terms of significant mineral resource endowments. In 2011 its in situ mineral resources were estimated to be worth about

The gold mining industry is a major contributor to the economy of Ghana. However, this contribution has been declining over the past decade. This decline coupled with the importance of the industry to the country's economy necessitated the need to analyse the performance of companies within the industry. Therefore, a cost performance analysis of …

This paper presents a simple Microsoft Excel® algorithm for constructing the curves. It also demonstrates how the constructed industry curves were used to analyse the …

Particle Swarm Optimization, etc. Among these algorithms, Evolutionary Algorithms are the most widely used meta-heuristics. In construction industry, a need for the optimization process was discussed in the traditional time-cost trade-off problem by (Kelley & Walker 1959). They assumed a linear relation between time and cost of an activity and
