Non-additive grey relational model: case study on evaluation of flexible pavement

In the real world, most attributes in system have inter-dependent characteristics in some degree and cannot be evaluated by the conventional additive measure. To solve this problem, one non-additive measure method, fuzzy integral, is introduced in the paper to prepare the dependent attributes in advance and give them independence before the grey relational analysis is conducted. The intention is to improve the accuracy and performance of conventional analyses. A non-additive grey relational model is established based on the conventional grey relational analysis. To reveal the feasibility of this model, a case study was conducted to study the effects of distress parameters on the flexible pavement in Taiwan. From the practical application, the rationality of this model can be shown.
