Dynamic models of coal-fueled power plants have previously been reported in the literature. Oko and Wang (2014) developed a gPROMS dynamic model for a 500 MW subcritical power plant and validated it at full load and three off-design conditions. However, the study did not consider optimization and equipment health under flexible operations.
Development of quarterly mine plans is time-consuming and requires consideration for many operational constraints and competing objectives. With lengthy turnaround times for updating quarterly plans, there is often limited opportunity to adjust quarterly plan details at the execution end of the planning process. Consequently, weekly and short timeframe plans may …
The application of mathematical optimization of production schedules can be traced back to the early works of Williams et al.
