摘要
根据Saaty的一致性正互反判断矩阵,提出了一种含参数β的正互反判断矩阵元素与优先权重新的逻辑关系。基于这种新的逻辑关系,提出一种求取优先权重的方法。指出当β取不同的值时,相应的优先权重也会不同,参数β代表决策者的偏好。通过算例说明了此种方法的合理性、科学性。
According to the consistent definition proposed by Saaty, a new logical relation between elements and priorities is proposed. Based on the proposed logical relation, a simple pragmatic method with a parameter β is developed to derive priorities, and some important conclusions are obtained. By taking different values of parameter β, the corresponding priorities will be different, which indicates that parameter β represents the preference of decision makers. Finally, numerical example is exam- ined to illustrate the developed method is feasible
