Abstract: Task scheme evaluation refer to numerous factor in the complicated environment so it is difficult to be overall for evaluation index.The article recommended a kind of hiberarchy guideline system，which made evaluation index in an all-round way through thinning to develop criterion layer.In addition to the improvement of the FAHP，the level amount of index system was unrestricted and the corresponding calculation amount increased not big.And througth changing the formula of calculating index value in the arithmetic，the resolving power is improved and the credibility of optimum scheme is increased.

Key words: FAHP, scheme evaluation, scheme optimization, fuzzy consistent matrix
