| 摘 要： | 灰色系统理论为系统分析和模拟提出了一系列新的概念、思路和方法，为系统的研究开辟了一条新途径。本文首先阐述了灰色系统理论的主要特色接着探讨以绝对值关联度为基础的现行关联度分析的存在问题及原因，提出用变化率关联度代替绝对值关联度，以克服其缺陷。算例表明这样处理使关联分析概念更明确、计算更简单、结论更合理。最后讨论了灰色模型的适用条件，指出其局限性。

| Abstract: | The grey system theory puts forward a serf ies of new concept, idea and method for the system analysis and simulation and opens up a new way for the investigation on system. In this paper the relational analysis and grey model in the grey system theory are discussed. The existed problems in the present relational analysis method based on the absolutevalue relational grade are investigated. In order to solve those problems the change-rate relational grade is recommended to replace the absolute -value relational grade. The calculation example shows that it makes concept more precise, calculation more simple and conclusion more reasonable for the relational analysis. The applicational conditions of the grey model are discussed in more detail and its limitations are also pointed out. |
