machine - implemented methods , systems , processing devices and machine - readable media are provided for simulating a mill reline , which involve collecting mill relining data and processing the relining data as simulation parameters using a mill relining model . the relining data generally include variables treated as discrete time / frequency distributions . simulated events for the mill reline may be generated based on the relining data . additional relining data relating to a specific existing site may be included as simulation parameters . the simulation may be used in determining an optimal work flow for carrying out the mill reline at a specific existing site , e . g ., where time to carry out the mill reline is minimized . the simulation may also be employed for benchmarking . the additional relining data may be provided in video format , and analysis of the video format data may be undertaken , e . g ., by an operator for refining and / or verifying the additional relining data , prior to utilizing the additional relining data as simulation parameters in the simulation model . the mill relining data may also include additional parameters , such as the size and quantity of the liners , the reline planning process and relining crew proficiency , the relining equipment and plant design surrounding the mill being relined , and the like .
