针对传统决策方法在评价指标量化和权值确定时主观性较强、误差较大的问题,综合运用区间数学理论法、层次分析法和区间关联分析法,建立了软土路基处理方案优选的区间层次决策法。通过对某工程软基处理方案进行优选,计算各方案的隶属度,得出各方案的优劣次序。研究结果表明:与模糊相似优先比等方法计算结果进行对比,优选结果一致;区间层次决策法充分考虑了主观判断的不确定性,将评价指标值和权值区间化,大大提高了决策精度,为路基软基处理方案决策提供了一种新方法。
Aiming at the problems of traditional subjective decision making method such as strong subjectivity and large error in the evaluation index weighting and weight determination, the interval between mathematical methods, analytic hierarchy process (AHP) and interval correlation analysis Level Decision Method. Through the optimization of a project soft foundation treatment program, calculate the membership degree of each program, draw the order of advantages and disadvantages of each program. The results show that the results are consistent with the results of fuzzy similarity priority ratio, and the results of the optimization are consistent. The interval-level decision method fully considers the subjective judgment of uncertainty and interval between the evaluation index and weight, which greatly improves the decision precision, It provides a new method for decision-making of roadbed soft foundation treatment.
