A multi-dimensional forward selection method for firms’ credit sale

In this paper, we propose a framework of the selection method for firms’ credit sale, including the concepts of multiple credit sale dimension, a credit sale space, imperfect identical credit sale status and εε-identical credit sale status. In addition, a forward selection model is established for credit sale of retail traders by optimization techniques. Finally, an example is illustrated to show the analytical potential of the proposed method in a real-life application.
