This article first presents several formulas of chance distributions for trapezoidal fuzzy random variables and their functions, then develops a new class of chance model (C-model for short) about data envelopment analysis (DEA) in fuzzy random environments, in which the inputs and outputs are...

The initial geometrical imperfections present in the thin plate structures play a vital role in determining the load carrying capacity, especially when they are subjected under axial compression. Moreover, it is impossible to manufacture thin plates without geometrical imperfections. Prediction...
