【摘要】：為提高突發(fā)事件應(yīng)急決策的科學(xué)性,考慮決策主體知識的不完善性及決策的模糊性,綜合運用殘缺判斷矩陣、線性求和理論,建立多決策主體參與的應(yīng)急群決策方法。引入殘缺直覺模糊矩陣,且改進(jìn)補全矩陣;根據(jù)得分值排序法,加權(quán)求和所有方案,建立最大化得分值線性規(guī)劃模型,求得最優(yōu)決策者權(quán)重;利用直覺模糊加權(quán)幾何(IFWG)算子集結(jié)綜合直覺偏好值,計算得分函數(shù),并對各方案進(jìn)行排序擇優(yōu)。算例結(jié)果表明,該方法適用于屬性權(quán)重及專家權(quán)重未知的群決策,且減小了專家在決策過程中的不確定性和猶豫性對決策結(jié)果的影響,從而提高應(yīng)急決策的有效性。
[Abstract]:In order to improve the scientific nature of emergency decision-making, considering the imperfection of decision-making subject knowledge and the fuzziness of decision-making, the emergency group decision-making method with multi-decision-making subject participation is established by using incomplete judgment matrix and linear summation theory. The incomplete intuitionistic fuzzy matrix is introduced and the complement matrix is improved. according to the score ranking method, the weighted summation of all schemes is established, and the optimal weight of decision makers is obtained by establishing the maximized score linear programming model. The intuitionistic fuzzy weighted geometric (IFWG) operator is used to aggregate the comprehensive intuitionistic preference value, calculate the score function, and sort and select each scheme. The results of numerical examples show that the method is suitable for group decision with unknown attribute weight and expert weight, and reduces the influence of uncertainty and hesitation on decision results in the decision process, thus improving the effectiveness of emergency decision.
