2、stics that people value in identifying these indicators fuzzy constraints are difficult to give exact values, while decision-making process has been one of psychological, subjective will and the work experience and other aspects influence decision-making process and therefore there is certainly ambi

3、guity 1, Water Resources and Hydropower Engineering Construction Layout Factors Construction advantages and disadvantages of the general layout scheme, involving many factors, from different angles to evaluate the evaluation factors generally have two categories, qualitative factors, and quantitativ

4、e factors of a classQualitative factors are mainly: 1Favorable production, easy to administer, facilitate the degree of life; 2During the construction process, the degree of co-ordination; 3The principal impact of construction and operation; 4Meet the security, fire, flood prevention, environmental

5、protection requirements; 5Temporary Works and the combination of permanent works and so onIndicators are mainly quantitative factors; 1Site preparation earthwork quantity and cost; 2. The extent of use of earth excavation; 3Temporary works of construction work quantity and cost; 4Workload and a vari

7、re prediction aboutTherefore, both qualitative factors, and the quantitative factors, there is uncertaintyWe know that the uncertainty of two different forms; one is uncertain whether the incident occurred in 11 random, the event itself the state of uncertainty 11 ambiguityRandomness is an external

8、cause in general uncertain, but ambiguity is an inherent uncertainty of the structureFrom the information point of view, the randomness involves only the amount of information, while the ambiguity is related to the meaning of informationWe can say that ambiguity is more profound than the randomness,

9、 the uncertainty more generally, especially in the subjective understanding of areas of role ambiguity is much more important than the role of randomnessRandom people for a lot of research has been carried out, achieved fruitful results; while ambiguity was ongoing and in-depth knowledge and researc

11、 difference intermediate division caused by the transition of a kind of uncertaintyConstruction Layout Design is no exception, in the arrangement of construction there are a large number of objective fuzzy factorsFor example, the construction of facilities, coordination between the levels of good an
