摘要

The basis of any successful materials transport system relies on sound knowledge of the key features of the system - haul trucks and shovels in the case of surface mining - and efficient operation and implementation of these features. Methods for estimating productivity and costs, and the dependent equipment selection process need to be increasingly reliable. Optimality is the desired result in any haulage system, however due to the stochastic nature of surface mining materials transport systems, rarely is the desired outcome achieved to the full extent. This work uses Ptolemy II which is an open-source software framework supporting the construction of actor-oriented systems with heterogeneous modeling capabilities. The design of a simulation system, targeting ways to build on and improve a hypothetical surface mine haulage system with variable travelling distances, was achieved within Ptolemy II. Using a discrete event simulation model, a discrete heterogeneous fleet was represented, its behavior simulated and the resulting performance indicators measured, finally allowing an effective fleet optimization to be conducted. The study confirms the suitability of using Ptolemy II as a viable option for producing simulation studies within a mining context.
