A comparative study of truck cycle time prediction …
Kefid · Purpose – The purpose of this paper is to compare the predictive capability of three methods of truck cycle time estimation in open‐pit mining: computer simulation, artificial neural networks (NNs), and multiple regressions (MRs). The aim is to determine the best method. The most common method currently used is computer simulation. Design/methodology/approach – …

Dump Truck Cycle Time Calculator to Help Make Decisions
Liming · Take this example: if a truck starts its first leg from Job Site A to Plant 1 and then to Job Site B, and each leg takes approximately 10 minutes, including loads and unloads, the total cycle time is 40 minutes. Every leg of a cycle time has a benchmark. On average, most legs, like loading at a quarry, run between 10-15 minutes.
