Decision Support for Bus Operations under Uncertainty: a Fuzzy Expert System Approach

摘要

This paper presents a novel approach to handle uncertainty in the daily operation of urban bus tran- sit systems using a straightforward framework. A fuzzy expert system is developed to properly for- mulate the current bus operation problem in Taiwan. To facilitate the construction of the fuzzy knowledge base and to allow feasible action alternatives of multiple action types to be generated for multiple abnormal conditions on multiple bus routes, the system is composed of three decision sup- port modules: demand, supply, and decision. The demand module determines the extra trip require- ment to cope with multiple abnormal conditions.
