The process of truck shovel assignment for optimization of the transport systems in open pit mining is performed using software models and algorithms. With the aid of the software and hardware mechanisms, great steps can be taken in intelligent assignment and control of truck shovel systems. In this paper, open pit mining transport system has been modeled based on TSP modeling. Using genetic algorithms, the optimized travelling path for trucks has been obtained. The software has the capability of compound modeling...

The truck and shovel transportation system is the most important part of the open pit mining operation because a considerable amount of the total mining costs is related to it. Reducing the transportation cost has a great impact on reduction of the total cost. One method to reduce the cost per ton in transportation systems is the optimization of the truck–shovel assignment. In this paper, software has been developed for optimal assignment of N trucks to M shovels with different grades of the minerals, based on m...

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 ...
