| 摘要： | The treatment of the spatial dimension in assessing infrastructure condition, modeling its deterioration, and, consequently, maintenance decision making is achieved through the development of a spatial distress model that provides the necessary structure for such a treatment. The relationship of the spatial model developed to the temporal deterioration modeling literature is presented. The spatial model developed recognizes two deterioration mechanisms: the "environmental" mechanism, which describes deterioration as a consequence of causal factors and exhibits both macroscopic and microscopic scales, and the "interactive" mechanism, which describes deterioration as a result of distress at a location influencing the deterioration of neighboring locations and exhibits a microscopic scale. The results of the application of the model for the identification of uniformly behaving regions appropriate for condition assessment emphasize the importance of the explicit recognition of the spatial dimension within the infrastructure management process. |
