There are two methods fixed and real-time assignment for improving the performance of transportation through truck- shovel system in open pit mines. The real-time assignment (RTA) method is a better manner for optimization process of transportation system in open pit mines, especially in the complex transportation systems. The most significant objective of the RTA method is, introducing a transportation system which cause to increasing production per time and decreasing cost per ton. In this study, a software base...

In this paper a combined (hybrid) model of fix and flexible with its software were presented. In the model, initially the trucks assignment operation using the fix approach was done and in the end of trucks operation cycle in the flexible method, trucks dispatching method was started. Results of fix assignment method implementation in each transportation scheduling period were used in the mentioned software and finally the fitness and most suitable shovel and truck combined system for the real-time assignment was ...
