Abstract:
The research, Reliability Investigation for Increasing Safety in Iranian Railway Systems via TPM, aims to evaluate maintenance in Iranian Railway Systems, and its corresponding factors in impacting safety. As the title indicates, this study focuses on safety in Iranian railway systems, and thus provides a history of the rail industry, as well as its history in Iran. Additionally, four maintenance types: regular, preventative, corrective and critical are evaluated. This evaluation is done for each maintenance type based on a series of factors rated based on a questionnaire distributed amongst experts. 37 experts were surveyed consisting of rail industry employees, as well as university academics in related fields. To analyze the data gathered from the experts, SPSS and Super Decision Software were used for statistical and AHP analysis. The results indicated that the most significant factors impacting railway safety are regular maintenance and corrective maintenance, and by focusing more on these two categories, Iranian railway safety will improve
