| dc.description.abstract | Operation and Maintenance Cost Analysis is an engineering economics technique that can be utilized to better formulate maintenance strategy and minimize the O&M cost of projects. It also helps in foreseeing the cost implications of maintenance actions over the service life a product. Addis Ababa Light Rail Transit (AALRT) is constructed using a loan (475M) USD as per ERC report that must be paid in 23 years. The Ethiopian Railways Corporation (ERC) should determine the income, operation and maintenance cost (O&M) of AALRT line in order to pay the loan on time. Thus, by investigating and analysing O&M Costs and optimization of the maintenance strategy the investment can minimize the O&M cost of the Light Rail Transit. The main objective of this research is to develop a decision support tool to AALRT Management for maintenance program and strategic plan through operation and maintenance Cost Analysis. The developed models for O&M cost analysis of railway track infrastructure can be used by managers to make necessary maintenance and renewal decisions. Probabilistic and Analytical methods have been used to predict failure time of the railway track components and analyse the O&M costs of the super structure of the track components. This research determines the total O&M cost of the railway track super structure components in the operation and maintenance phase. It also identifies optimal maintenance and renewal (M&R) strategies for track super structure components. From the analysis, the total cost value for 25 years is 207,572,671Birr. It is observed from the analysis that as more load is applied in MGT, the more M&R costs will be expected. | en_US |
