Once pit shell candidates are created in a Lerch Grossman algorithm, the truly strategic planning begins with scenario analysis of multiple schedules representing different strategies. The pit shells for the interim stages have a greater impact on NPV than the stages in later years of the mine life; therefore, optimum interim pit shell ...
Production Scheduling of Open Pit Mines Using Particle ... Determining an optimum long term production schedule is an important part of the planning process of any open pit mine; however, the associated optimization problem is demanding and hard to deal with, as it involves large datasets and multiple hard and soft constraints which makes .
