Reasoning by analogy contain broad sense and narrow sense. The broad sense analogy indicates generally the inference based on genus, which equal to what we now say inference (contain deduce, induce, analogy). The narrow sense analogy only points several typical inference form based on same genus that the ancients discussed in Mohist Argument: pi, mou, yuan, tui, which mostly equal to what we now say analogy.

推类有广义和狭义之分：广义推类泛指在类的基础上进行的推理，相当于我们现在所说的推理；狭义推类仅指《墨辩》中论及的譬、侔、援、推等几种典型的、以类同为依据的推理类型，大致相当于当今所说的类比推理。

Based on grey system theory and fuzzy theory, uncertain decision making problems and several relative articles were studied, then points out the advantage and shortage of them when dealing with grey fuzzy set were pointed out.
