Application of Supply Chain Tools In Power Plant- A Case of Rayalaseema Thermal Power Plant

Inventories are considered to be one of the important weapons of supply chain to improve the efficiency of any manufacturing unit. Continuous availability of inventories are the prime requirement for uninterrupted working .To effectively manage inventory levels, it is essential to consider the appropriate reorder points as well as the optimized ordering quantity. The proposed system uses the Genetic algorithm to find the optimized ordering quantity at proper reorder point , by considering the power plant live data as a practical case study. The proposed approach is implemented in Matlab  platform version 7.10 Key words.

Spare Parts Management of Aging Capital Products

Spare parts are critical for operations of capital products such as aircraft, refineries, trucks, etc/, which require maintenance regularly. Original Equipment Manufacturers (OEMs) bear the responsibility of undisrupted maintenance service and spare parts flow for their capital products. Due to various factors OEMs lose their spare parts suppliers occasionally and these losses threaten the reliability of their maintenance service and capital products. In this thesis, we consider supply risk in management of spare parts inventory. The thesis consists of two parts: First we develop advance indicators for future supply problems of spare parts and suggest a model utilizing those indicators for inventory control of spare parts. Our results indicate that OEMs can save significantly by utilizing those indicators together with our model in their daily business. Second, we consider secondary markets and their effects on spare parts supply chains of OEMs. Secondary markets are chap supply sources for spare parts needs of OEMs. Therefore effective usage of them yield significant cost savings and boost service rate of OEMs. Furthermore, secondary markets are sources of competition since low prices on those markets attract some customers of OEMs. These two factors are considered from the perspective of spare parts inventory control. In the second part, we conclude that for OEMs it is beneficial to use secondary markets as a supply source as long as they adjust their selling prices accordingly
