Productivity Estimation to Diagnosis Support in Bauxite ...

Abstract: This paper proposes a methodology to estimates the productivity and support the diagnosis in an open-pit mine using fuzzy logic. The variables used in the estimation process are: loading queues, dumping queues, relocation time and cycle time. After the estimation, a detailed analysis of the unproductive hours is applied in order to identify which fuzzy rules are active.
