Abstract—This is the case-study of an automobile Industry in India. The prices of Critical Spare Parts (CSP) are range from tens to hundreds of thousand rupees. As the equipment’s operate, some critical spare parts need to be replaced due to wear and tear. If appropriate amount of critical spare parts are not prepared, machines may not be able to function, thus resulting in a waste of resources. However, estimation of the critical spare parts consumption is a complicated subject (Billinton and Ahllen, 1983). This investigation focuses on forecasting the critical spare parts and evaluating the prediction performance of different forecasting methods. Exponential smoothed model, Least Square method and moving average method (MA) are used to perform CSP demand prediction, so as to effectively predict the required number of CSP which can be provide as a reference of spare parts control. This investigation is verified by comparing the predicted demand and actual demand of critical spare parts in semiconductor factories

Index Terms—Critical spare parts, Exponential smoothed model, Least square method, Moving Average method (MA)
