“…Among these formulations, it is possible to find reserve, slope, mining capacity, processing capacity, and stockpiling constraints (Lamghari et al, 2014a;Lamghari and Dimitrakopoulos, 2016). The features include metal uncertainty (Lamghari Dimitrakopoulos, and Ferland, 2014b), geometallurgical modelling (Navarra, Grammatikopoulos, and Waters, 2018a), supply uncertainty (Goodfellow and Dimitrakopoulos, 2016;Senecal and Dimitrakopoulos, 2020), the actions of mineral concentrators (Navarra et al, 2017), prevention of excessive movement of mining equipment between benches (Gholamnejad, Lotfian, and Kasmaeeyazdi, 2020), and commodity price uncertainty (Rimélé, Dimitrakopoulos, and Gamache, 2020). Montiel and Dimitrakopoulos (2015) have extended their focus beyond a single mine and consider the production planning of a 'mining complex'.…”
