Abstract:As an important link in the complex system engineering project of open-pit mining, the quality of boundary determine the performance of the project to a large extent. However, the traditional design method cannot effectively measure the impact of uncertainties on the realm optimisation process. In this article, a coal price time series forecasting model that considers the amount of redundancy is proposed, which combines an improved sparrow search algorithm (ISSA) and a least squares support vector regression m… Show more
