considering a thermal power generation plant large number of spares and materials need to be readily available during an outage project of a power generation plant. However, it is not cost-effective to keep stock of high-valued spares and those made from exotic materials. Thus, the unavailability of some spares sometimes occurs and that delays the progress of the outage. At times, it is uncertain when the procured materials might be delivered and that could imply a delay of the project. Create a list of spare parts and materials needed for the outage project. Based on the inventory management models which are: EOQ, JIT, and ABC inventory analysis, develop a systematic approach towards the ordering of the spare parts, separate high valued from low valued materials and ensuring that the parts are available for the outage project.
