OPTIMIZATION OF WARRANTY PERIOD AND PRODUCT RELIABILITY FOR AUTOMOTIVE PART SUPPLIER : Warranty claim is one of the major cost factors for automotive part manufacturers who consider to improving their competitiveness in quality, cost and delivery. Key indicator to measure the product performance in actual usage condition is the product reliability .The purposes and results of this research were; 1) To study the optimization of product reliability which is the opportunity for automotive part supplier to take action to improve quality level or supplier can sell extended warranty to requesting customers. Weibull ++ Nevada chart format is recommended method for this research. This method can yield various benefits such as minimize warranty reserve cost, minimize risk of reserve shortfall (hamper customer service and hence deteriorate customer satisfaction) by using real warranty data and forecast the number of potential product claims. 2) To study the optimization of warranty period in contract between automotive part supplier and OEM for applied the appropriate warranty period for calculating warranty reserve budget. Typically, automotive part makers face a greater risk than car makers as they need to maintain quality of products longer. The result was shown the optimum warranty reserve period is 65 months and extended warranty has been calculated and possible to extend warranty period by adding12 or 24 months by set selling price in market at least 26% or 31%, respectively, higher than normal price. 3) To propose a methodology for analyzing warr
