These results are important because they show that the proposed approach generates effi cient dispatch decisions for trucks operating in a real environment, reducing operating costs, increasing production and making the mine more competitive. Psychomotor learning incorporates physical activity with learning. It should be noted that Cycle time only covers the time taken to manufacture the product and excludes the time it takes to procure raw materials and the post-processing time like delivery etc. This way, you can constantly track how long youre spending to ensure youre not exceeding your average cycle time. According to the literature, material transportation represents 50 per cent of the operating costs for an open pit mine. The most common method currently used is computer simulation.

The only difference in the hauler cycle time for a given route derives from the difference in fixed time to fill the hauler, loader vs. excavator. Calculating cycle times helps you determine how long it takes you to deliver value to your customer. The investigation on road conditions was focused on the effects of rolling resistance, grade resistance and road widths from the road between bench 540 in pit 103 to the Zinc oxide medium grade stockpile. Cycle time calculator helps calculate the average time it takes to complete the production of a unit. All thanks to hardworking dinosaur sous chefs! Therefore, the times in the 1st column are all of their start times. The paper clearly indicates that computer simulation methods used in predicting truck cycle times in openpit mining underestimate and overestimate the results for short and long hauls, respectively. Lets get started! Cycle Time is the actual production time. It appears that both NN and regression models are superior in their predictive abilities compared to computer simulations.
