摘　　要：以何种尺度来测量人们在进行预测与决策时心理测度上的模糊性 ,是预测是否可靠乃至决策能否成功的关键。为此 ,提出离散型模糊数这一尺度及其在预测与决策问题中的算法 ,并通过实例验证了该方法的有效性。In prediction and decision problems, there are many relevant uncertain factors affecting on the psychological judgements of decision-makers. It′s the key to adopt a suitable implement to express the fuzziness of this psychological measure. The discrete fuzzy number and its algorithms proposed here can appropriately express the uncertainty and fuzziness of prediction and decision under fuzzy environment. Its feasibility and validity are shown by examples.
