This paper addresses the integrated production scheduling and preventive maintenance programming problem (IPSPMP) in an open-pit iron ore mine, located in the state of Minas Gerais, Brazil. This problem consists of determining the quantities produced of each product, as well as the preventive maintenance schedule. In other words, it can be seen as a …

The cyclic nature of underground mining production activities has been identified as fundamental to the management of schedule constraints through application of the concept of natural commencement of the next activity following completion of a prior activity in the production cycle (Nehring and Topal, 2007; Nehring et al., 2010b). This is a ...

Queuing of rakes at the TLOs is an important factor in the local scheduling decisions considered when looking at the rail silo. For the iron ore scheduling problem, two elements of the deployed algorithm that are particularly important include (i) the demand-driven nature of the algorithm, and (ii) the technique of disruption propagation.

The Iron Ore Mining Industry Around 98% of iron ore is used to make steel and goes di-rectly to primary steel plants (MII 2006). It has been argued that iron ore is more integral to the global economy than any other commodity, except perhaps oil (FT 2009a). The trade in iron ore makes it the second-largest commodity market by value after crude oil.
