【正文】 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 indepth knowledge and research in theAll people involved in the system, carried out by people planning, feasibility studies, evaluation of decisionmaking, design and management, and therefore, can not ignore the objective world of things in the human brain, one by one to reflect the uncertainty of ambiguity, it is an objective 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 and general is an accurate value can not be describedTherefore, the arrangement can not ignore or avoid the construction of the fuzziness existing in the process, but should be objective and deal with ambiguity of this objective, understand the rules for people planning, demonstration, evaluation and decision, design and management to provide a scientific basis and methods As the construction layout of the content involved in more programs fuzzy factors exist, the traditional construction arrangement he considered the existence of ambiguity, but in decisionmaking process has fuzzy information precision, not a real fuzzy optimizationTherefore, the program should focus on optimization of fuzzy factors into account, the ambiguity should be reflected in the decisionmaking on the index, index weightsFor quantitative indicators, mainly the amount and cost of the project issues, its value can be found in engineering materials and design documents to determine by calculation, the results are the values of the parameters and experienceAs every engineer39。s understanding of things is not the same experience in a certain range of parameter changes, the results also in a certain rangeFor qualitative indicators, according to experts, engineering experience, through expert scoring method, set the value of statistics to determineSuch subjective factors, the knowledge structure and decisionmaking preferences play a major roleBut in practice, due to the plexity of objective things and the people39。s thinking on the use of fuzzy concept, to describe with precision the number bees very difficult, but with some, left and the like get fuzzy concept to describe the more reasonableDetermine the weights of evaluation indexes, there are many
