Abstract:

The flourishing development of the big data era has led to the prevalence of decision situation involving multi-source hybrid information. Random-aggregation-based evaluation theory provides an effective solution for decision problems in such situations. However, existing research on random-aggregation-based evaluation has only focused on the fundamental measurement, neglecting the tracking function for the dynamic development of alternatives. In statistics, the concept of an “index” plays a role in dynamically monitoring the changes of phenomena. Therefore, the main objective of this paper is to study the calculation of random-aggregation-based index.Specifically, it focuses on addressing the following issues: (i) How to normalize multidimensional hybrid information data? (ii) How to establish benchmarks based on random aggregation conclusions? (iii) How to calculate the value of random-aggregation-based index?Motivated by the aforementioned issues, the primary contributions of this paper include: (i) A hierarchical dimensionless normalization method is proposed for the base period and reporting period, separately, to achieve a smooth index update. (ii) An index compilation method is presented in terms of the superiority matrix, in which a new idea of “introduction of reference objects” is used to determine the benchmark and the index value is calculated using the increment of the superiority. (iii) The concept of “Difference Matrix” is proposed and its random aggregation is given algorithm from the perspective of coordinate projection, along with discussing the associated index compilation method. (iv) The mathematical test reveals that the proposed indices, similar to the other classical indices, has the properties of identity, commensurability, determination, and proportion.Finally, an example concerning the performance appraisal is analyzed and it is found that the proposed index can accurately track the relative performance among employees in uncertain complex environments. Compared with existing dynamic comprehensive methods, the proposed index can effectively reduce computational workload and minimize result bias.
