Automatic formation of short-term plan based on the long-term plan on open-pit mine using O-1 integer programming
Abstract：To solve the confliction between long-term and short-term production plan on open-pit mine, established a 0- 1 integer programming model of short-term plans by time period applying with space-time development, and a new con- cept of ＂super combo blocks＂ was proposed and the progress logic of short-term plan was dealt with. It implemented the design of long-term plan, dividing blocks from strip benches and dynamic displaying by secondary development using the TCL language on the Surpac software platform. The short-term plan could be automatically optimized by call- ing LindoAPI mathematical software under Visual C ＋ ＋ environment. It solved the problem that the short-term plan cannot be drawn out from automatic optimization based on long-term plan, but the program running time could be mi- nutes or few hours. The reliability and efficiency of the method is proved in the work field.
