We consider the multiple time period short-term production scheduling problem for a network of multiple open-pit mines and ports. Ore produced at each mine, in each period, is transported by rail to a set of ports and blended into products for shipping. Each port forms these blends to a specification, as stipulated in contracts with downstream customers. This problem belongs to a class of multi...

Mine geological disaster is a complex non-linear system. The traditional prediction model has the disadvantages of low accuracy and poor reliability. In order to solve this problem, open-pit mine slope displacement taken as research object. Based on new algorithm extreme learning machine (ELM), intelligent sparrow search (SSA) are introduced determine weights thresholds input layer hidden ELM. ...
