Abstract

Spare part is one of the common precaution used by a company to ensure the availability of their machine in an optimum level. By optimizing the spares inventory, the power plant company can reach the optimum level of availability and indirectly will increase the reliability of the plant. Any lack of spares can lead to company losses in form of maintenance cost, operation loss and material loss. In addition, the lack of spare also can increase the mean time to repair and lead to the production stoppages. However, if the number of spares are more than the requirement, company will bear some losses as the spares will not be in used and may lead to the obsolete items. Besides that, if the spare was protected by an insurance and being kept in the inventory, it may lead to the waste of money and inventory space that can be used in another purpose such as preventive and predictive maintenance. Thus, the company needs to analyse the failure and the stock movement to optimize the spare and increase the reliability of the plant. There are some analysis that can be used to optimize the number of the spare such as Pareto analysis, Failure Trend analysis and Movement analysis. To conduct this analysis, engineer and technician must be aware and monitor the movement of the spare to get a significant data that can be used in the analysis. Therefore, the analysis can be more accurate and the optimised list of spare can be issued by the company. All the steps to optimizing spares was covered in this paper.
