Systems Engineering - Theory & Practice 

TL;DR: A novel optimizing method based on the model of autonomous animats, and referred to the behavior of fish school, using the bottom-up development process to be a kind of efficient optimizing method.

TL;DR: On the basis of the arithmetic aggregation operator and hybrid aggregation operator, an approach to group decision making with interval-valued intuitionistic judgment matrices is given and some of their desirable properties are investigated in detail.

TL;DR: To improve the prediction abilities of machine learning methods, a support vector machine (SVM) on structural risk minimization was applied to customer churn prediction and it is found that the method enjoys the best accuracy rate, hit rate, covering rate, and lift coefficient, and therefore, provides an effective measurement for customers churn prediction.

TL;DR: In this paper, a simple calculating formula of background value is reestablished, which can be used to established GM (1, 1) medel of equidistance series and non-equidarity series, and the application range of GM(1, 1) model is extended.
