| Abstract |
Many years ago, railway track degradation was a very interesting topic for several organizations to conduct research seriously for the purposes of safety and high level of reliability in infrastructure. Degradation factor was the main point of this study, so fuzzy multi attribute decision making method (FMADM) was used to analyze railway track defect and degradation to select rehabilitation plan on schedule. Related research and literature was reviewed, and questionnaire was designed for asking opinions of the experts working for the state railway of Thailand (SRT) including related party in selecting the rehabilitation plan. The findings reveled that defect and degradation can lead to a high risk of derailment influenced by usability aspect. Defect code can be classified into 4 types according to the international union of railways (UIC) using the pairwise comparison method. Each type is different in the starting point and extension direction of railway track crack with contingency index below 0.01. The experts specified the severity of code 200: transverse break defect without apparent origin level of severity is the most with relative weight of 0.396 followed by code 135: star-cracking of fishbolt holes with relative weight of 0.275 and the least severity is. Code 1321: horizontal. cracking at web-head with relative weight of 0.142. The analysis result based on FMADM indicated that the experts considered that railway track structure replacement plan was better than railway track rehabilitation plan with importance weight of 0.620 and 0.380, respectively.
