区间灰色语言变量在包装企业创新能力评价中的应用研究

Research on Interval Grey Linguistic Variable and Its Application in Evaluation of Innovation Ability of Packaging Enterprises

借助区间灰色语言描述包装企业创新能力评价问题中的不确定信息,通过Power算子分析准则间存在关联的多准则群决策问题,并在此基础上构建包装企业创新能力评价模型。首先,结合区间灰色语言变量与Power算子的概念,提出区间灰色语言Power混合加权平均算子等一系列算子。然后,构建评价值为区间灰色语言变量的多准则群决策模型。最后,以纸包装企业科技创新能力评价为例说明其可行性和有用性。

By using the interval grey language to describe the uncertain information in the evaluation of packaging enterprise’innovation ability,based on the analysis of the multi-criteria group decision-making issue considering the interrelationship of individual criterion through the Power operator,an evaluation model of the packaging enterprise’s innovation ability was built.Firstly,by combining the concepts of interval grey linguistic variables and Power operator,a series of operators such as interval grey linguistic power hybrid averaging operator was proposed.Then,a multi-criteria group decision-making model with the criterion values taking the form of interval grey linguistic variables was constructed.Finally,an illustrative example of the evaluation of paper packaging enterprise’technological innovation capability was used to demonstrate the feasibility and usefulness of the proposed method.
