Abstract

NPN (negative-positive-neutral) calculi, a family of three mathematical structures are introduced for qualitative reasoning. NPN crisp logic extends the usual 4-valued model (+, -, 0, ?) to a 6-valued model (1, 0, +1, (-1, 0), (0, +1), (-1, +1)) and adds one more level of specification to the usual model. NPN fuzzy logic extends the NPN model to the space ( For all (x,y) mod x, y epsilon (-1, 1) and x>

NPN微积分:由三个严格q -代数组成的一族

NPN(负-正-中性)微积分，一个由三种数学结构组成的家族被引入定性推理。NPN清晰逻辑将通常的4值模型(+，-，0，?)扩展为6值模型(1,0，+1，(-1,0)，(0，+1)，(-1，+1))，并在通常的模型上增加了一个规格级别。NPN模糊逻辑将NPN模型扩展到空间(For all (x,y) mod x,y epsilon(- 1,1)和x>
