The objective of this paper is to explore and create a sourcing model for the wind turbine companies. To establish the model, the existing system to be studied carefully.This study was carried out in one of the wind turbine company in southern part of India. The problem statement is the company is under continuous loss.Jhe main reasons for the loss is due to delay in execution of projects, higher inventory, government policies, etc.Out of this main reason the inventory has been taken by me for the study. The entire system supply chain system has been studied carefully and find out the root cause of the problem. Root cause of the problem is basically the changes in production schedules. Different methodology has been discussed and finally the Make to order concept/tool has been introduced. The inventory level has come down drastically .Also Pull system is introduced for the procurement of higher value components. These systems are not used in this wind turbine company earlier, so the real benefit of inventory reduction is established. This shows the methodology of make to order and pull system really benefitting such kind of industry. This system can be taken as a base for sourcing model and further improvement can be studied in the further research. The constraints of the system are all the receipt of material is considered as quality cleared, and the delivery as per the schedule .no delay in supply is considered. This research can further establish by considering these constraints.
