针对准则值为直觉三角模糊数,准则间相互关联的多准则决策问题,提出基于Choquet积分的决策方法.该方法首先利用偏好函数定义方案在各准则下的优序关系,若模糊测度已知,则直接利用Choquet积分进行求解;若准则集上的模糊测度未知,则利用部分决策信息和最小方差法建立二次规划模型,求解模糊测度,再利用Choquet积分进行决策.最后通过实例表明了该方法的有效性和可行性.
Aiming at the multi-criteria decision making problems in which the guideline values are intuitionistic triangular fuzzy numbers and the rules are interdependent, a decision-making method based on Choquet integral is proposed. Firstly, the preference function is used to define the optimal order relation under each criterion. If the fuzzy measure is known, The Choquet integral is used to solve the problem directly. If the fuzzy measure on the criterion set is unknown, the quadratic programming model is established by using the partial decision information and the least variance method, the fuzzy measure is solved and the Choquet integral is used to make the decision. Finally, Effectiveness and feasibility
