Abstract:
Recently, the reduction of greenhouse gas emissions and environmental damage has become increasingly important. In this paper, a new mathematical model has been proposed for supplier selection and order allocation by considering the green routing problem. The proposed mathematical model is a multidimensional and multidimensional one that considers such assumptions as routing, storage, and product shortage. Moreover, for the evaluation of the efficiency of the proposed approach, it was implemented at IranKhodro Company and the obtained results indicated the applicability of the proposed approach

Abstract:
The purpose of the present research is the study of the effects of anisotropy of the layers of rock-soil on the fracture mode, failure pattern and failure mechanisms of layers. For this purpose, single-axis loading on the 36 samples, in a way that 9 samples with the angle of 0 degree that three of them were included 50 percents of rock and 50 percents of soil as one- layer, two-layer and three-layer and three layers of them were included 75 of rock and 20 percents of soil as a one-layer, two-layer and three-layer. In a way that was said 9 samples were at an angle of 30 degrees, and 9 samples had 60 degree angle and 9 samples had the 90 degrees. In general, in the present research the effect of Non-coplanar fracture was studied.
