synthetic ratio

It makes use of fuzzy sets for describing uncertain characteristic parameters, multilevel fuzzy synthetic decision and the principle of maximum membership function for determining task priority level, an algorithm which makes multilevel decision model dynamically for decreasing invalidation ratio of judging task priority level.
