shovels and dump trucks are among the most commonly-used equipment in the mining industry, and their performance is highly interdependent. In recent decades, equipment capacity has been increased, leading to cost reductions and production increases. However, this increase in capacity has brought both benefits and drawbacks. For example, when dump trucks or shovels are idle, there are opportunity costs in addition to operating costs. The Production Capability of a mine gives a good overview of the current state of the mine compared to a 100% utilization of the mine. High production and availability of mining equipment are critical due to their high opportunity costs. To determine the Production Capability at the Sarcheshmeh copper mine, data were collected on waiting times, delays during the operation, and loading cycles. After determining the distribution functions for the collected data, the mining operations were simulated in AnyLogic software, which allows the creation of various scenarios from different aspects. The simulation results show the effects of correct and ineffective management in a mine. Based on the eva‎luations and comparison of different scenarios, the inefficiency of the fleet management system at the Sarcheshmeh copper mine can be clearly seen. Long queues at the crusher represent one of the most critical bottlenecks in the mine in the simulation software. At the Sarcheshmeh copper mine, the most effective way to increase production is to increase fleet utilization through the use of fleet management systems (dispatching) which can lead to a 15% increase in production for 85% utilization. Choosing an appropriate dispatching strategy that fits the conditions of the mine can have a significant impact on improving utilization, reducing operating costs, increasing production, and properly managing a mine. Increasing utilization along with the purchase of new dump trucks and replacing them with worn-out fleets can increase mining production by 26% and bring the mine closer to the goal of extracting 185 million tons of ore and waste.
